I'll focus on problem 19 and problem 22

============================================================

Problem 19

Answers:

x = 87x+15 = 102

-------------------------------

Explanation:

The horizontal lines are parallel. Note the arrow markers along the interior portion of the lines. These similar markers tell us how the lines pair up to be parallel to one another.

Since the horizontal lines are parallel, this means the angles in question are congruent. They are corresponding angles.

x+15 = 102

x = 102-15

x = 87

Which leads to

x+15 = 87+15 = 102

============================================================

Problem 22

Answer: y = 27

-------------------------------

Explanation:

We have a pair of alternate exterior angles. They are congruent due to the parallel lines.

Let's solve for y.

7y-55 = 3y+53

7y - 3y = 53+55

4y = 108

y = 108/4

y = 27

Answers

Answer:

x+6 y+3

Step-by-step explanation:

The translation shows a horizontal shift to the left by 6 units and vertical shift up by 3 units

Reflection of coordinate points

Reflection of any coordinates are mirror images of each other.

The reflection rule of the coordinate over the x-axis is given as:

(x, y) -> (x , -y)

Using the coordinate (-1, 2) on the image on the left and (5, 1) for the coordinate on the right.

Reflecting (-1, 2) over the x-axis is (-1,-2). In order to determine the translation used from (-1, -2) to (5, 1)

(-1+x, -2+y) = (5, 1)

-1 + x = 5

x = 6

-2 + y = 1
y =3

The translation shows a horizontal shift to the left by 6 units and vertical shift up by 3 units

Step-by-step explanation:

Move the 6w to the left and 7 to the right.

4w-6w=31+7

Combine like terms

-2w=38

Divide by negative 2.

w=-19

4w - 6w = 31 + 7
-2w = 38
-2w/-2 = 38/-2

Which of the following equations represent exponential growth functions? Choose all that apply.
a) f (x)=4^x
b) f (x)=(1/4)^-x
c) f (x)=(2/3)^x
d) f (x)= (2.3)^x
e) f (x)=(.8)^x

Answers

Option:-

a) f(x) = 4^x is applicable

b) f(x) ={ (1/4)^-x = 4^x }is applicable

c.) f(x) = (2/3)^x is not applicable

d.) f(x) = (2.3)^x is applicable

e.) f(x) = (.8)^x is not applicable

Options (a), (b) and (d) are exponential growth functions.

What is Exponential function?

An exponential decay is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier which is less than 1.

By the Exponential decay form,

An exponential decay is in the form: y = abˣ

(a) f (x)=4ˣ is applicable as 4>1

(b) f (x)=(1/4)⁻ˣ is applicable as (1/4)-1=4>1

(c)  f (x)=(2/3)ˣ is not applicable because 2/3<1

d) f (x)= (2.3)ˣ is applicable as 2.3>1

e) f (x)=(.8)ˣ is not applicable, 0.8<1.

So options (a), (b) and (d) are applicable for exponential growth functions.

Angles in straight line add to 180 degrees
180-142=38
180-133=47
180-38-47=95
180-95=85 degrees
B

Answer:

B. 85 degrees

Step-by-step explanation:

To find the top angle inside the tringle, do 180-133 = 47. To find the angle on the left, do 180 - 142 = 38. Do 180 - 47 + 38 = 95 to find the final angle. Then do 180-95 = 85 to find the angle wanted. This is all about using lines, because the angles on both sides of the line must add to 180 if one of the lines they lie on is the same. Hope this makes sense.
