We know that the original width was 5, and that after the enlargement the width is 45. To calculate the scale factor we divide the final width between the original one, then:
Therefore the scale factor is 9.
Answer:
(The solution is (4, -11).
Step-by-stp explanation:
Let f(x) = g(x) = y:
y = 3x − 23
y = -4.5x + 7 Subtract the second equation from the first to eliminate y:
0 = 7.5x - 30
7.5x = 30
x = 4
Plug this into the first equation:
y = 3(4) - 23
y = -11.
Answer:
z = 8
x = 5
Step-by-step explanation:
Because it is a parrallelogram 3z - 4 and 2z + 4 is congruent if you make it an equation and equal each other (3z - 4 = 2z + 4) It will be 8
They are also equal to each other so you will do the same thing
4x - 6 = x + 9
x = 5
Answer:
s = 116°, q and t are 64°
Step-by-step explanation:
isoceles so r and s are the same and q and t are the same. therefore q and t are 180-116 = 64
