A. 10

B. 42

C. 14

D. 350

Which is a solution of the equation y=4x+3?

A. (5,17)

B. (17,5)

C. (4,19)

D. (4,16)

What is the simplified form of the expression 7[63: (5^2-2^2) - 1]?

7[63: (5^2-2^2) - 1]

= 7[63: (25-4) - 1]

= 7[63: (21) - 1]

= 7[3-1]

= 7 (2)

= 14

answer is C. 14

Which is a solution of the equation y=4x+3?

answer is

C. (4,19)

y=4x + 3

19 = 4 (4) + 3

19 = 16 + 3

19 = 19

The second one is C. you plug in the first number for x and the second number for y. its saying 19 = 4 (4) + 3. and 19 = 16 + 3 is 19 = 19 so C is the answer.
