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

The grocery store had 4lb bag of oranges for 4.80$ and a 6lb bag for 6.18$ . What is the difference of the 4lb bag of oranges and the 6lb bag of oranges
Answers
Answer:
$1.38
Step-by-step explanation:
The grocery store had 4lb bag of oranges for 4.80$ and a 6lb bag for 6.18$ . What is the difference of the 4lb bag of oranges and the 6lb bag of oranges
The cost difference is calculated as:
Cost of 6lbs of oranges - Cost of 4lbs of oranges
Cost of 6lbs of oranges = $6.18
Cost of 4lbs of oranges = $4.80
Hence,
= $6.18 - $4.80
= $1.38
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.

w = -19
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
-2w = 38
-2w/-2 = 38/-2

Answers
Answer:
11y + 20
Step-by-step explanation:
Given that:
Distance south = 5y miles
East = (2y + 10) miles
Final = (4y + 8) miles
Total cycle in terms of y
Take the sum of the distances :
5y + 2y + 10 + 4y + 8
11y + 20

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 pointsReflection 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

What is the value of n?

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.
