Answer:
239
Step-by-step explanation:
Write the equation. Fill in the given values, and solve for the unknown,
z = k√x
717 = k√9
k = 717/3 = 239
The constant of proportionality is 239.
Answer:
Both graphs have a “y-intercept” at (0,0), so i believe the answer would be they don’t have y intercepts
Step-by-step explanation:
Answer:
A = 7 x 9.3
A = 65.1 yd²
Step-by-step explanation:
<em>(I am assuming that either 7 or 9.3 refers to the height. It is unclear.)</em>
A = bh
Answer:
Step-by-step explanation:
Both equations have -7y. You can eliminate them by subtracting one equation from the other:
Multiply equation 1 by -1, then add it to equation 2:
-2x + 7y = 74
3x - 7y = -83
———————
x = -9
2x - 7y = -74
2(-9) - 7y = -74
-7y = -56
Y = 8
(x,y) = (-9, 8)
