You need to multiply 75. 222 = 16650
So the answer is C
For Part A: You would put a dot on -8 on your line graph, and also put a dot on 13 as well. This is representing the temperatures of White Plains, NY.
For part B: The answer would be 21 degrees warmer.
Hope this helps!
Find two points and draw a line through them
y = 1/2(2) + 5
y = 1 + 5, 6
One point is (2,6)
y = 1/2(0) + 5
y = 5
Second point is (0,5)
I inserted a graph on desmos for example
Answer:
Heather sent 28, Pablo sent 19, and Shen sent 76.
Step-by-step explanation:
This will be your equation
123 = H (Heather) + P (Pablo) + S (Shen)
This is the extra stuff
P + 9 = H
4P = S
Substitute so there is only P then use that to solve for the rest
123 = P + 9 + P + 4P
Then solve
123 = 6P + 9
123 - 9 = 6P + 9 - 9
114 = 6P
19 = P
Then substitute for the extra equations
19 (P) + 9 = 28 (H)
19 (P) * 4 = 76
