If x increased by the product of 8 and y is 76, and 8x increased by the product of 8 and y is 104, what are the values of x and y?

x = 4, y = 9

Step-by-step explanation:

(1)   x + 8y =  76

(2) 8x + 8y = 104

             7x = 28     Subtracted (1) from (2)

(3)            x =  4      Divided each side by 7

      4 + 8y = 76      Substituted (3) into (1)

            8y = 72      Subtracted 32 from each side

              y =   9     Divided each side by 8

The solution is x = 4, y = 9

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
