STEP 1: Multiply second equation by -3.
After multiplying we have the following system:
3x+4y−3x+3y=8=−36
STEP 2: add the two equations together to eliminate x from the system.
7y=−28
STEP 3: find y
<u>y=−4</u>
<u></u>
STEP 4: substitute the value for y into the original equation to solve for x.
3x+4(−4)=8
<u>x=8</u>
Answer:
Part 1 and 2:
A. Forearm (in) Foot (in)
Sarah 10 9
Sam 11. 10
Emma 8 7
Mom 10 9
Dad 11 10
B. M=9-7 over 8-10 the answer is 2 over 2.
C. For every forearm the foot is one inch smaller.
Part 3:
A. 0.860(17)+3.302
B. Y=17.922. They are slightly different. Keren’s has a greater rate. I think the values are different because they have different origins.
C. Yes, because it is an important part for rate of change. Yes it is a function because there can’t be any exponents greater than 1, and its not a straight line if you plug it in.
Step-by-step explanation:
This is just an example dont you the names
$360.00*.28= 100.80
<span>Or do a portion </span>
<span>28%/100%=100.8/x </span>
<span>Then cross multiply </span>
<span>10080=28x </span>
<span>x=360</span>
Answer:
d = 11
Step-by-step explanation:
10 - d = -34 - 5d
10 (- d + d) = -34 (- 5d + d)
10 = -34 - 4d
10 + 34 = (-34 + 34) - 4d
44 = 4d
44/4 = 4d/4
d = 11
The midpoint of (x1,y1) and (x2,y2) is
just average them
(4,1) and (-2,4)
the midpoint is
(1,-1.5)
