10/4= 2.5
5/2.5= 2
2 would be your first answer
32x2.5= 80
80 would be your second answer
Hope this helped
Answer:
The top one is (3x−2)(x+5)
the bottom one is (3x−2)(3x+2)
Step-by-step explanation:
Answer:
The system has one solution.
Step-by-step explanation:
To find the number of solutions of the system, we equal both equations for y.
If we have ax = b, in which both a and b are different of 0, we have one solution.
If both a and b are 0, we have infinite solutions.
If a is 0 and b is not, there are no solutions.
y=6/7x-8 and y=7/9x+10/9
So





Both a and b are different of 0, so the system has one solution.
Answer:
Step-by-step explanation:
Multiply the three dimensions
12 x 6 x 8 = 576 cm^3
F(x) = -3x + 7
y = -3x + 7
x = -3y + 7
-3y + 7 = x
-3y = x - 7
y = -1/3x + 7/3
f^-1(x) = -1/3x + 7/3
