what variable are we to find?
Answer:
what??
Step-by-step explanation:
Answer:
x = 11
Step-by-step explanation:
Slope(m) is given by:
m = change in y ÷ change in x
3/4 = (4 - 1) ÷ (x - 7)
= 
Cross multiplying gives:
3x - 21 = 12
3x = 33 , x = 33/3 = 11
Answer:
7,13,37,55,103
Step-by-step explanation:
y = 5 + 2x^2
if x =1
y = 5 + 2(1)^2
1^2 = 1
2 x 1 = 2
y=5 + 2 or y = 7
you substatute each one in for x to solve for y
<u>7x + 3 = 9x - 7</u>
Subtract 7x from each side: + 3 = 2x - 7
Add 7 to each side: 10 = 2x
Divide each side by 2 : <em>5 = x </em>
