Evaluate each expression.

Step-by-step explanation:

1) a) 3 - 4*5² = 3 - 4 * 25

                    = 3 - 100

                    = -97

c) (2 -8)² - 2*(-3) = (-6)² - 2*(-3)

                         = 36 - 2*(-3)

                         = 36 + 6

                         = 42

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
