Answer:y=15/4
Step-by-step explanation:
start with general form y = kx. substitute in the pair of values you know for x and y.
75/8 = k(5) multiply both sides by 1/5 to solve for k, getting
15/8 = k
So your equation is y = (15/8)x substitute 2 for x to find your new y.
y = (15/8)2
y = 15/4
The difference between the two cities are that each temp is different their 14c away because their is a minus on the eight
255 is the answer because 143+86=229, 229+23 is 255
Answer:
x = ±3
Step-by-step explanation:
Step 1: Write equation
7x² = 63
Step 2: Solve for <em>x</em>
- Divide both sides by 7: x² = 9
- Square root both sides: x = ±3
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
7(3)² = 63
7(9) = 63
63 = 63
7(-3)² = 63
7(9) = 63
63 = 63
