Answer:

29

Step-by-step explanation:

okay so we are going to substitute 10 where the x variable is in this problem

2x + 9​

like this:

2(10) + 9​

and then we do order of operations by multiplying 2 by 10 then adding 9:

2x + 9 =

2(10) + 9 =

20 + 9 = ​​

Answer:

D.

b = 175; which is the initial # of pages to start

Step-by-step explanation:

you can find the slope to find b or y-intercept (x=0) for equation

y=mx+b

to find m = (y2-y1)/(x2-x1)

(x1,y1) = (9, 100)

(x2, y2) = (15, 50)

m = (50-100) / (15-9) = -50/6 = -25/3

let use point (15, 50)

y=mx+b

50 = -25/3*x + b

50 = (-25/3)*(15) + b

50 = -125 + b

b = 175; which is the initial # of pages to start

Answer:

7/6

Step-by-step explanation:

in order for it to perpendicular then its need to be the negative reciprocal of it, so you flip the sign making it positive and do the opposite of the slope like for ex if it was 1/2 it would have been 2

176/2pi = 28.0

3.89 - hundredths place but not so sure because if you round you get 3.90 so either D or C

Answer:

Step-by-step explanationthe answer is 19 because your trying to find 180 and your timing that 3 by what ever gets you the extra of 180 so you do 19 ×3 equaling 57 and then you add in that 123 and it all equals 180

The value of x is 19°.

A linear pair of angles are formed when two lines intersect each other at a single point.

Given a pair of angles which are on a straight line and so, making a linear pair,

123°+3x=180°

3x = 57°

x = 19°

Hence, x = 19°

Answer:

B

Step-by-step explanation:

The factor of the cubic expression 4x³ + 10x² – 6x will be 2x, (x + 3), and (2x – 1). Then the correct option is B.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The expression is given below.

⇒ 4x³ + 10x² – 6x

The degree of the expression is 3. Then the expression is a cubic expression. Then simplify the expression, then we have

⇒ 4x³ + 10x² – 6x

⇒ 2x(2x² + 5x – 3)

⇒ 2x(2x² + 6x – x – 3)

⇒ 2x[2x(x + 3) – 1(x + 3)]

⇒ 2x(2x – 1)(x + 3)

The factor of the cubic expression 4x³ + 10x² – 6x will be 2x, (x + 3), and (2x – 1). Then the correct option is B.

Answer:

yes they are congruent by sas

Step-by-step explanation:

Side angel side shows that's the 2 given segments bisect one another. The two angles are on opposite sides as well making it sas.

Answer:

We know that opposite angle are congruent.

[tex]10x + 10 = 11x + 3 \\ \\ 10x - 11x = - 7 \\ - x = - 7 \\ x = 7[/tex]

So, We found out that x = 7,

So, Putting x = 7 in 10x+10

[tex]10 \times 7 + 10 \\ \\ = 70 + 10 \\ \\ = 80[/tex]

So, The measure of angle 10x+10 is 80.

The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is [tex]\frac{dy}{dx}[/tex] or:

[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

Example:

Let's say you're give this table:

x: 1, 2

y: 1, 2

Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1

Do the same for x

Now plug the values taken in the slope formula and you get:

[tex]\frac{2 - 1}{2 - 1}[/tex]

[tex]\frac{1}{1} = 1[/tex]

Therefore the slope is 1.

Answer:

Rise/run

Rise over run.

Step-by-step explanation:

To find the slope pick two perfect spots on the line when the coordinates are not decimals.

Then, take those  two points and figure out the distance. You will use rise/run.

so rise is how much you either go up or down and run is how much you either go right or left. so how much you'll go up or down? how much will you move right or left?

Lets say you have to go up 5 and then left 7 to get to the coordinate.

That's your slope! you went up so it's positive and you went left so it's negative. Rise over run : rise 5 left 7 so, 5 and -7 which is 5/-7 and that's your slope!

Answer:

10

Step-by-step explanation:

So because AC is intersected at the middle, or the midpoint, being E, you can say that both sides of AC; AE and EC, are equal to each other. You can make 4x-3=3x-1 and combine like terms to get X on one side by itself. First, you want to subtract 3x from both sides to move the x from left side and only have it on the right. You should x-3=-1. Then, you want to remove the -3 from the left side and bring it to the right to have x by itself. To cancel the -3 on the left side you have to add 3 on both sides. You should have x=2. Now that you have x, you can plug it into both AE and EC, then add them together. You should have 5 for AE and 5 for EC, and adding them up makes 10. Hope I could help :)

Step-by-step explanation:

the only possible resulting function after dilation is y = 5x. Option D is correct

Given a coordinate point (x, y), if the coordinate is dilated by a factor of "k", the resulting coordinate point will be at (kx, ky).

Note that both coordinates were multiplied by the factor "k"

Given the expression y = x, for this expression to show a dilation, we can multiply the input variable by an integer.

From the given option, we can see that the only possible resulting function after dilation is y = 5x

Answer:

1. The value of the variable, y is 11

2. (B) QRS is congruent to segment (E) ΔWXY by the hypotenuse leg congruency criteria

Step-by-step explanation:

1. The lengths of the sides of the given triangles ABC are  AB = 14, BC = 27, AC = 19, and ∡A = 32°

The lengths of the sides of the given triangle FGH, FG = 14, GH = 19, FH = 2y + 5, ∡G = 32°

From the given parameters, we have;

Segment AB (AB = 14) is congruent to segment FG (FG = 14)

Segment AC (AC = 19) is congruent to segment GH (GH = 19)

Angle ∡A (∡A = 32°) is congruent to angle ∡G (∡G = 32°)

∴ ΔBAC is congruent to ΔFGH by the Side-Angle-Side rule of congruency

Therefore, segment BC is congruent to segment FH by Congruent Parts of Congruent Triangle are Congruent, CPCTC

Segment BC = Segment FH by definition of congruency

∴ 27 = 2·y + 5

2·y + 5 = 27

2·y = 27 - 5 = 22

y = 22/2 = 11

y = 11

The value of the variable, y = 11

2. For option A. the vertices of triangle ABC are A(-7, 4), B(-4, 1), C(-2, 5)

The length of the sides are;

The length of side AB = √((-4 - (-7))² + (1 - 4)²) = 3·√2

The length of side BC = √((-4 - (-2))² + (1 - 5)²) = √20

The length of side AC = √((-2 - (-7))² + (5 - 4)²) = √26

For option B. the vertices of triangle QRS are Q(3, -4), R(3, -1), S(7, -1)

The length of the sides are;

The length of side QR = √((3 - 3)² + ((-4) - (-1))²) = 3

The length of side RS = √((7 - 3)² + (-1 - (-1))²) = 4

The length of side QS = √((3 - 7)² + ((-4) - (-1))²) = 5

For option C. the vertices of triangle DEF are D(-2, 6), E(1, 3), F(3, 7)

The length of the sides are;

The length of side DE = √(((-2) - 1)² + (6 - 3)²) = 3·√2

The length of side EF = √((3 - 1)² + (7 - 3)²) = √20

The length of side DF = √((3 - (-2))² + (7 - 6)²) = √26

For option D. the vertices of triangle TUV are T(-6, -5), U(-6, 1), V(4, 1)

The length of the sides are;

The length of side TU = √(((-6) - (-6))² + ((-5) - 1)²) = 6

The length of side UV = √(((-6) - 4)² + (1 - 1)²) = 10

The length of side TV = √(((-6) - 4)² + ((-5) - 1)²) = 2·√34

For option E. the vertices of triangle WXY are W(-6, 4), X(-6, 1), Y(-2, 1)

The length of the sides are;

The length of side WX = √(((-6) - (-6))² + (4 - 1)²) = 3

The length of side XY = √(((-6) - (-2))² + (1 - 1)²) = 4

The length of side WY = √(((-6) - (-2))² + (4 - 1)²) = 5

Therefore;

Segment QR of ΔQRS is congruent to segment WX of ΔWXY

Segment RS of ΔQRS is congruent to segment XY of ΔWXY

Segment QS of ΔQRS is congruent to segment WY of ΔWXY

Whereby QS and WY are the hypotenuse side of ΔQRS and ΔWXY respectively, because QS = WY = 5 = √([tex]\overline {QR} ^2[/tex] + [tex]\overline {RS} ^2[/tex]) = (√(3² + 4²)

and also RS = XY, by the definition of congruency, we have;

QRS is congruent to segment ΔWXY by the hypotenuse leg congruency criteria

The equation that represents the parabola is 20(y + 5) = (x - 1)² ⇒ b

Step-by-step explanation:

The form of the equation of the parabola is (x - h)² = 4p(y - k), where

Let us use the form above to solve the question

∵ The vertex of the parabola is (1, -5)

→ That mean (h, k) is (1, -5)

∴ h = 1 and k = -5

∵ Its focus is at (1, 0)

→ That means (h, k + p) is (1, 0)

∴ k + p = 0

→ Substitute the value of k

∴ -5 + p = 0

→ Add 5 to both sides

∵ -5 + 5 + p = 0 + 5

∴ p = 5

→ Substitute the values of h, k, p in the form above

∵ (x - 1)² = 4(5)(y - -5)

→ Remember that (-)(-) = (+)

∴ (x - 1)² = 20(y + 5)

→ Switch the two sides

∴ 20(y + 5) = (x - 1)²

∴ The equation that represents the parabola is 20(y + 5) = (x - 1)²

Answer: b. 20(y+5) = (x-1)^2
