Answer:
1. b 2. b
Step-by-step explanation:
1. In the graph it shows a negative slope so we can immediately eliminate a and c since they have a positive slope as shown in the equation. Then the initial value is the y coordinate when x is 0. In the graph you can see that when x is 0 y is 18 so the equation would be h= -3+18
2. In the problem it says that Jennifer is paid $2,200 as a base salary. This means that this is her initial value. Then you can see that she gets paid 300 extra for every car she sales. This is the rate of change. The equation will be y=300x+2,200
fyi 300 goes first because it is the rate of change and those always go first.
hope this helps! :)

Find the Greatest Common Factor and Least Common Multiple for 20 and 8. GCF is LCM
Answer:
GCF= 4 LCM=40
Step-by-step explanation:
Factors of 8:1,2,4,8
Factors of 20:1,2,4,5,10,20
Greatest common factor is 4 because it is the highest factor in both sets.
Multiples of 8:8,16,24,32,40,48,56,64,72,80...etc
Multiples of 20:20,40,60,80,100,120,140...etc
Lowest common multiple is 40 because it is the lowest multiple in both sets.

What is the measure of ZA degrees?
Answer:
Since this is an isosceles triangle, the angles opposite to the equal sides will also be equal
Therefore,
angle ABC = angle ACB
We are given that angle ACB is 30 degrees
Hence, angle ABC = 30 degrees
We know that according to the angle sum property, the sum of all interior angles of a triangle is 180 degrees
So, angle ABC + angle ACB + angle CAB = 180 degrees
replacing the variables with values we already know
30 + 30 + angle CAB = 180
angle CAB = 180 - 60
angle CAB = 120 degrees
Hence the measure of angle A is 120 degrees
Please find angles s and k
Answer:
s-64 and k-116

Phone company 1 offers a plan that costs 35.99 and includes unlimited texting, phone company 2 offers a plan that costs 19.99 and charges 0.25 per text
For what number of texts does the 2nd phone company plan cost more than the 1st phone company
Write and solve an inequality that models this situation. define your variables.
Answer:
at 65 texts , co 2 costs more
19.99 + .25x > 35.99
x= number of texts
Step-by-step explanation:
19.99 + .25x = 35.99
x= number of texts
.25x= 35.99-19.99
.25x=16
x=16÷.25

The equation y =0.7x represents the distance Henry hikes in miles over time in hours. The graph
represents the rate that Cark hikes. Determine which hiker is faster. Complete the explanation
Henry’s unit rate is ___ miles per hour. Clark’s unit rate is 1.5 miles per hour . So, ____ is faster.
Answer:
Henry’s unit rate is 0.7 miles per hour. Clark’s unit rate is 1.5 miles per hour . So, Ckark is faster.
Step-by-step explanation:
Distance covered by Henry is represented by y = 0.7x, where x = time (hrs), and y = distance (miles).
Distance covered in 1 hour by Henry would be:
y = 0.7(1) = 0.7 miles per hour
Distance covered by Clark in 1 hour = 1.5 miles per hour
Ckark covers more miles per hour than Henry covers in one hour, therefore, Ckark is faster.

A unit rate of 4 deliveries per hour.
What is the rate?Rate is the special ratio in which two different terms are in different units. a number, amount, or degree measured in relation to another object. a payment or charge that is calculated depending on another sum. more specifically: the premium per insurance unit. transitive verb rate.
Given that 16 deliveries are done in 4 hours. from that we can drive no. of deliveries in one hour. let's assume deliveries in one hour is x
For, x per hour = 16/4
x per hour is 4
Therefore the appropriate value for the unit rate of 4 deliveries per hour.

C. 9
D. 10
Answer:
7
Step-by-step explanation:
You have to but the numbers in order than you cross each of the ends until you get the middle number/median
Answer: 9
Step-by-step explanation:
The median in math is basicly the middle of the list. First, put the list in order from least to greatest. Then, find the middle. If there is no middle, add the two numbers in the middle. Add them together, and divide the sum by two. The quotient is the median.
In this case, there is a middle. The middle is nine. Nine is the median.

Raul and Ivan each make a number pattern, as described.
• Raul's pattern: start with 15, add 2
• Ivan's pattern: start with 11, add 3
What number in Raul's pattern and in Ivan's pattern is the same in a pair of corresponding terms?
(A) 17
(b) 21
(C) 23
(D) 26
23
26
Answer:
Option C. 23
Step-by-step explanation:
To know the correct answer to the question given above, let us determine the sequence of Raul and Ivan. This is illustrated below:
From the question given above,
Raul's pattern: start with 15, add 2
Ivan's pattern: start with 11, add 3
For Raul:
Raul's pattern: start with 15, add 2
1st term = 15
2nd term = 15 + 2 = 17
3rd term = 17 + 2 = 19
4th term = 19 + 2 = 21
5th term = 21 + 2 = 23
6th term = 23 + 2 = 25
For Ivan:
Ivan's pattern: start with 11, add 3
1st term = 11
2nd term = 11 + 3 = 14
3rd term = 14 + 3 = 17
4th term = 17 + 3 = 20
5th term = 20 + 3 = 23
6th term = 23 + 3 = 26
Summary
Term >>>>> Raul >>>>>> Ivan
1 >>>>>>>>> 15 >>>>>>>> 11
2 >>>>>>>>> 17 >>>>>>>> 14
3 >>>>>>>>> 19 >>>>>>>> 17
4 >>>>>>>>> 21 >>>>>>>> 20
5 >>>>>>>>> 23 >>>>>>>> 23
6 >>>>>>>>> 25 >>>>>>>> 26
From the calculations made above, we can see that in the 5th term, both Raul and Ivan has the same number as 23.

Write the equation of the line with the given point and slope.
(-5, -3); slope = -3/5
A line in point slope form is y = mx + b
m = the slope
b = y-intercept
So far our line looks like: y = -3/5x + b
Let's plug -5 into x and -3 into y to solve for b
-3 = -3/5(-5) + b
Let's multiply -5 by -3/5
-3 = 3 + b
Subtract 3 from both sides.
-6 = b
Our line is: y = -3/5x - 6
