Answer:
x = 12
Step-by-step explanation:
their the same length so plug em equal to each other
x+5 = 2x-7
add 7 to both side to get x+12 = 2x
subtract x from both side to get x = 12
Answer:
Option A.
Step-by-step explanation:
we have

Simplify the right side of the equation
we know that

so
The expression is

therefore
x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 2 times a
Formula: A = pi(r)^2
1/4(2)^2pi
1/4 * 4 pi = just pi
The area would be 3.14
9514 1404 393
Answer:
1. proportional, 6
2. not proportional
Step-by-step explanation:
<u>Table 1</u>
Each y-value is 6 times the corresponding x-value, so the variables are proportional, and y = 6 times x.
<u>Table 2</u>
The ratios of y to x are 2, 4, 8, so are not the same. The values are not proportional.
Slope = (9-3)/(5-2) = 6/3 = 2
