Answer:
x = 1
y = -3
Step-by-step explanation:
if y = x - 4
then reorganise the first equation
4 (x - 4) = 9x -21
4x - 16 = 9x - 21
5 = 5x
x = 1
It wouldn’t be any of those- because its in point-slope form ( y-y1=m(x-x1) ) the slope is -2/3, then the -5 (y) turns to +5 because there’s 2 negatives- since the x is positive it stays subtraction
The Correct equation would be y+5=-2/3(x-4)
Hope that helps :)
Answer:
v = 1
Step-by-step explanation:
-6(7v - 5) - 3 = 3(v - 6)
distribute -6 into 7v - 5
-42v + 30 - 3 = 3(v - 6)
distribute 3 into v - 6
-42v + 30 - 3 = 3v - 18
add 30 and -3 together
-42v + 27 = 3v - 18
subtract 3v from both sides
-45v + 27 = -18
subtract 27 from both sides
-45v = -45
divide by -45 on both sides
v = 1
2(L * W) + 2(L * H) + 2(W * H) = surface area
