Answer:

Y= 15 or (0,15) that is the answer, hope it's not to late

Answer:

x=3

Step-by-step explanation:

By isolating the variable y in the left side of the linear equation, we will get:

y = 4x - 10

Here we have a linear equation and we want to solve this for y, to do this, we need to isolate the variable y in one of the sides of the equation.

The linear equation is:

5y + 10 - x = 4y + 3x

Moving all the terms with y to the left side and the others to the right side, we get:

5y - 4y = 3x - 10 + x

If we simplify this we get:

y = 4x - 10

This is the linear equation solved for y.

Standard deviation is a statistic that measures the dispersion of a data set relative to its mean and is calculated as the square root of the variance. The standard deviation is calculated as the square root of the variance by determining the deviation of each data point from the mean.

If the data points are farther from the mean, there is more variance within the data set; therefore, the wider the data is spread, the larger the standard deviation.

Yes, Giselle's statement is always true, she can draw a congruent triangle with the help of two sides and one angle, this rule of congruence is called the SAS property of congruency.

Giselle can create the precise triangle if Bianca gives her two sides and one angle.

Both triangles will now be congruent by SAS (side angle side) congruency.

Giselle's claim will always be accurate according to the congruency theorem.

The acronym "SAS" stands for side, angle, and side, and it makes it apparent that if any two sides and one angle of two triangles are the same, then those triangles are said to be congruent with one another.

For instance, if the triangle ABC has dimensions of 2 cm by 3 cm by 6 cm and the triangle PQR has dimensions of 4 cm by 3 cm by 6 cm and has an angle of 75 degrees, both of these triangles will be regarded as congruent triangles by the SAS theorem.

Simply put, two triangles are said to be congruent if their two sides and one angle are similar to those of another triangle.

The equation of a line is 2x + 5y = 8.

The given equation is :

y = 5/2x + 4

Here we have to find the equation of a line perpendicular to the given line passing through the point (-1,2).

The slope of a line is 5/2.i.e., [tex]m_{1}[/tex] = 5/2

To find the slope of a line perpendicular to the line we have a formula:

[tex]m_{1}[/tex]×[tex]m_{2}[/tex] = -1

[tex]m_{2}[/tex] = -1 /[tex]m_{1}[/tex]

[tex]m_{2}[/tex]= -1 × 2/5

     =-2/5

The equation of a line is:

y = mx + c

The slope is -2/5 and the point is (-1,2)

c = y-intercept

So by putting the value we have:

2 = -2/5 × (-1) + c

c = 8/5

y   = -2/5x + 8/55

y = -2x + 82x + 5y = 8

Therefore the equation of a line is 2x + 5y = 8.

The unit rate of the given parts are :

1)  37.037 index cards

2) 25.64 index cards

An item's unit rate is its price for one of it. This is expressed as a ratio with a one as the denominator. For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second. Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate.

The denominator of a unit rate is always 1. Therefore, divide the denominator by the numerator so that the denominator equals one in order to determine the unit rate. The unit rate is 50km/5.5 hours = 9.09 km/hour, for instance, if 50km are traveled in 5.5 hours.

1 ) $4.05 for 150 index cards

Thus for $1 we will get = 37.037 index cards

2) $1.17 for 30 index cards

Thus for $1 we will get = 25.64 index cards

Step-by-step explanation:

Create 5 additional columns on the given table for x², x³, x⁴, xy, and x²y.

Calculate the values and add the sum of each column.

(See attachment 1).

Use the matrix equation for determining the parabolic curve, entering the sums from attachment 1:

[tex]\displaystyle a \sum x{_i}^4+b \sum x{_i}^3+c \sum x{_i}^2=\sum x{_i}^2y_i[/tex]

[tex]\implies 74446.015625a+6046.90625b+520.25c=248662.875[/tex]

[tex]\displaystyle a \sum x{_i}^3+b \sum x{_i}^2+c \sum x{_i}=\sum x{_i}y_i[/tex]

[tex]\implies 6046.90625a+520.25b+48.5c=22987.5[/tex]

[tex]\displaystyle a \sum x{_i}^2+b \sum x{_i}+c n_i=\sum y_i[/tex]

[tex]\implies 520.25a+48.5b+5c=2313[/tex]

Solve for a, b and c using a calculator:

Insert these values (rounding to 3 decimal places) into the quadratic formula [tex]y=ax^2+bx+c[/tex] :

[tex]\large\boxed{y=-14.380x^2+299.970x-950.851}[/tex]

To find the profit (y) for a selling price of 16.75, substitute x = 16.75 into the found quadratic equation:

[tex]\implies y=-14.380(16.75)^2+299.970(16.75)-950.851[/tex]

[tex]\implies y=39.157...[/tex]

Therefore, the profit is $39 to the nearest dollar.

Note: Attachment 2 is the two-variable regression analysis as calculated by an online graphing calculator, proving that the y-value is 39 (nearest whole number) when x=16.75.

The tail length of an alligator whose body length is 4.2 feet will be 3 feet.

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. Mathematically, direct proportionality is represented by a straight line and it equation is of the form -

y = kx

k = y/x

where [k] is the constant

Given is an alligator's tail length [T] varies directly as its body length [B]. An alligator with a body length of 2.8 feet has a tail length of 2 feet.

We can write as -

tail length [T]  [tex]\alpha[/tex]  body length [B].

Therefore -

T/B = K    [Constant]

We can write -

T₁/B₁ = T₂/B₂

2/2.8 = T₂/4.2

T₂ = (2 x 4.2)/2.8

T₂ = 3 ft

Therefore, the tail length of an alligator whose body length is 4.2 feet will be 3 feet.

The total surface area of the cylinder in question is 428.93 m².

How are the parameters of a cylinder determined?
A cylinder is a three-dimensional solid with a parallel circular base and top. The overall height of the cylinder is the perpendicular distance between the top and base.
The area with just curved surfaces, leaving the circular top and base, is referred to as the curved surface area.
Total Surface Area is the combined area of the bases and the curved surface.
Mathematically, curved surface area = 2πrh, where r = radius, h = height of cylinder;
Total surface area = 2πrh + 2πr², where r = radius, h = height of cylinder.

Given, the curved surface area of the cylinder = 352 m²
Height of the cylinder = h = 16 m
Using the formula established above, we have 2πrh = 352 --(i)
Substituting other values in (i), we get 2*3.14*r*16 = 352 ⇒ r = 3.50 m
Again, total surface area of cylinder = 2πrh + 2πr²
Substituting all values, we get TSA = (2*3.14*3.50*16) + (2*3.14*3.50²)
= 428.93 m²
Thus, the total surface area of the cylinder in question is 428.93 m².

The required transformation of the function is 1 unit left and 5 unit down.

Given that,
To determine the transformation of the parent function y=|x|. y=|x-1|-5.

The graph is a demonstration of curves which gives the relationship between the x and y-axis.

Here,
The function y=|x| is an absolute function,
when we add 1 unit left and 5 unit down to the function, the function arises as y=|x-1|-5. It implies the transformation of function as -1 on the x-axis and -5 units on the y-axis.

Thus, the required transformation of the function is 1 unit left and 5 unit down.
