∠4 and ∠10 are a pair of alternate interior angles.
∠8 and ∠13 are a pair of co-interior angles.
∠3 and ∠4 are a pair of linear angles.
What are corresponding angles?
When two parallel lines are intersected by another line, comparable angles are the angles that are created in matching corners or corresponding corners with the transversal (i.e. the transversal).
What are alternate interior angles?
When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines. At two different locations, the transversal passes through the two lines that are coplanar. These angles indicate whether or not the two provided lines are parallel to one another. When a transversal intersects two parallel lines, the angles that are created inside are equal to the alternate pairings of that transversal. Alternate interior angles are what they are termed.
What are alternate exterior angles?
The pair of angles on the outside of the two parallel lines but on the other side of the transversal are known as alternate exterior angles.
What are linear pair of angles?
When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°. These are also referred to as additional angles.
Following the above literature,
∠1 and ∠5 are a pair of corresponding angles since angles are created in matching corners or corresponding corners with the transversal.
∠15 and ∠7 are corresponding angles since angles are created in matching corners or corresponding corners with the transversal.
∠4 and ∠10 are a pair of alternate interior angles.
∠8 and ∠13 are a pair of co-interior angles.
∠3 and ∠4 are a pair of linear angles since pair's total angles are always equal to 180°.

A line passes through the point (−10, 4) and has a slope of 3/2. Write an equation in slope-intercept form for this line.
The equation of the line in slope intercept form is y = 3/2x + 19
What are linear equations?Linear equations are equations that have constant average rates of change.
Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the equation of the line?The given parameters are
Slope, m = 3/2
Points, (x1, y1) = (-10, 4)
A linear equation is represented as
y = slope * x + y-intercept
i.e.
y = m(x - x1) + y1
So, we have
y = 3/2(x + 10) + 4
Expand
y = 3/2x + 15 + 4
Evaluate the like terms
y = 3/2x + 19
Hence. the linear equation is y = 3/2x + 19

Find the points on
y = x³ + 6x² - 15x + 1 at which the
gradient is zero.
Answer:
(-5, 101) or (1, -7)
Step-by-step explanation:
The gradient of a function is zero when its first differential is zero
Taking first derivative of y = x³ + 6x² - 15x + 1
we get
[tex]\dfrac{dy}{dx} = \dfrac{d}{dx}(x^3+6x^2-15x\:+\:1)[/tex]
[tex]= \dfrac{d}{dx}(x^3)+ \dfrac{d}{dx}(6x^2) - \dfrac{d}{dx}(15x)\:+\: \dfrac{d}{dx}(1)\\\\[/tex]
[tex]= 3x^2 + 2(6x) - 15 + 0\\\\\\= 3x^2 + 12x - 15x\\[/tex]
Set this first differential to 0, find the solution set for x
[tex]3x^2 + 12x - 15x =0[/tex]
This is a quadratic equation which will have 2 solutions for x.
First divide throughout by 3
[tex]= > x^2 + 4x - 5 = 0[/tex]
Factor the term:
[tex]= > x^2 + 4x - 5 = 0\\\\== > (x -1)(x + 5) = 0\\== > x - 1 =0 \text { or } x + 5 =0\\\\[/tex]
This means x = 1 or x = -5 is the solution set
To find the y value corresponding to these values of x, plug in each of these x values in the original equation and solve for y
Plug in x = 1 into equation x³ + 6x² - 15x + 1
=> 1³ + 6(1)² - 15(1) + 1
=> 1 + 6 - 15 + 1
=> -7
So one point is (1, -7)
Looking at the choices we can eliminate the first and last choices
Looking at choices 2 and 3 we see that only one of them has x = -5 which is the other solution value. This is the second choice
So the correct answer is second choice
(-5, 101) or (1, -7)
Note we did not have to go through the pain of computing y for x = -5

What is 1+1? Express in number form.
The number form of (1 + 1) will be (1 + 1) only.
What is number form?When a person who experiences number forms thinks of numbers, a mental map of the numbers automatically and unconsciously appears. Numbers are translated into specific spatial locations, and this translation may vary from person to person. In his book The Visions of Sane Persons, Sir Francis Galton first described and named number forms (Galton 1881a). They have been classified as a type of synesthesia in later studies (Seron, Pesenti, and Nol 1992; Sagiv et al. 2006).So, 1 + 1 in number form:

Theo is saving $8 per week for a vacation he is taking. He started off with some money in savings, but less than $8. At the end of his weeks savings, he had a total of $52. How much money did theo start of with?
To find the money at start let us use an equation
Since he puts $8 per week
Then his rate is 8
Since he has a total of $52 after some weeks
We must find the nearest number to 52 in table 8
Since 6 * 8 = 48 the nearest number to 52 in table 8
Then he did that for 6 weeks
52 = 8(6) + x
Let us find x
52 = 48 + x
Subtract 48 from both sides
52 - 48 = 48 - 48 + x
4 = x
He started with $4

Figure NN is the result of a transformation on Figure MM. Which transformation would accomplish this?
The transformation that is used is a translation of 3 units upwards.
Numerous different coordinate systems can be used to describe geometrical figures.
The connection between several systems is defined by coordinate transformations, which offer formulas for the coordinates in one system in terms of the coordinates in another system. For example, if the polar axis on a plane is the positive x axis and the origins of the Cartesian coordinates (x, y) and the polar coordinates (r), respectively, are the same. The transformation of the coordinates from the polar to the Cartesian coordinate system is x = r cos α and y = r sin α.From the diagram of the graph we can see that the transformation that is used is translation of 3 units upwards.

Write an equation of the line passing through (4,-2) that is parallel to the line -3x minus 4y =5
Answer:
Step-by-step explanation:
y=4x3
Answer:
Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.
First, rearrange -3x - 4y = 5 into y = mx + c form.
-3x - 4y = 5
-4y = 3x + 5
y = -3/4x - 5/4
Since parallel lines have the same gradient, equation of line is y = -3/4x + c.
Substitute (4,-2) into the equation to find c.
-2 = -3/4(4) + c
c = 1
Hence, equation of line is y = -3/4x + 1.
For a normal distribution, it is known that the mean is zero and the standard deviation is 1. Be sure to draw and label a normal distribution for each problem. Find the probability that a z score is between -1.15 and 1.98.
To find the probability between two z-scores on a normal distribution, we can use a z-score table.
A z-score table gives the probability of a data less than the corresponding z-score, like in the picture:
So, if we want the probability between 1.98 and -1.15, we need to do the following:
[tex]P(-1.15However, usually z-score tables go only from z = 0 and above, so we need a way to consult the negative z.Since the normal distribution in symmetric around z = 0, we have that:
[tex]P(z<-1.15)=P(z>1.15)[/tex]And since the whole distribution give a 100% probability, or an area of 1, we have that:
[tex]\begin{gathered} P(z<1.15)+P(z>1.15)=1 \\ P(z>1.15)=1-P\mleft(z<1.15\mright) \end{gathered}[/tex]So, in the end, we have:
[tex]\begin{gathered} P(-1.151.15) \\ P(-1.15So, we can consult the values for the probabilities of z < 1.98 and z < 1.15 on the z-score table:[tex]\begin{gathered} P(z<1.98)\approx0.9761 \\ P(z<1.15)\approx0.8749 \end{gathered}[/tex]So, the total probability is:

The sum of the measures of the second and third angles is three times the measure of the first angle. The third angle is 21 more than the second. Let x,y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.
The measure of all the three angles of a triangle will be 45°, 57° and 78° respectively.
What is Triangle?
A triangle is a three sided polygon , which has three vertices and three angles, whose sum is equal to 180 degree.
Given that;
The sum of measures of the angles of a triangle is 180.
The sum of the measures of the second and third angles is three times the measure of the first angle.
The third angle is 21 more than the second.
Now,
Let the measures of all the three angles are x , y and z.
Since, The sum of measures of the angles of a triangle is 180.
So, we can formulate;
x + y + z = 180° .... (i)
The sum of the measures of the second and third angles is three times the measure of the first angle.
So, we can formulate;
y + z = 3x ... (ii)
The third angle is 21 more than the second.
So, we can formulate;
z = 21 + y ... (iii)
Substitute value of z in equation (ii);
y + 21 + y = 3x
3x = 2y + 21
x = 2/3 y + 7
So, We can substitute x = 2/3y + 7 , y = y and z = 21 + y in equation (i), we get;
x + y + z = 180°
2/3 y + 7 + y + 21 + y = 180
2/3y + 2y + 28 = 180
8/3 y = 180 - 28
8/3 y = 152
y = 152 × 3 / 8
y = 57°
Hence, x = 2/3y + 7
x = 2/3 × 57 + 7
x = 2 × 19 + 7
x = 45°
And, z = 21 + y
z = 21 + 57
z = 78°
Thus, The measure of all the three angles of a triangle will be 45°, 57° and 78° respectively.
