Answer:
x = -23
x = -33
Step-by-step explanation:
-10(x+5) + 9x = -73
-10x - 50 + 9x = -73
x - 50 = - 73
x = -73 + 50
x = -23
-5(x + 8) + 2x = 59
-5x - 40 + 2x = 59
-3x - 40 = 59
-3x = 59 + 40
-3x = 99
x = 99/-3
x = -33
Answer:
D
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
here (h, k ) = (3, - 2 ) , then
y = a(x - 3)² - 2
to find a substitute the point (4, 3 ) into the equation
3 = a(4 - 3)² - 2 ( add 2 to both sides )
5 = a × 1² = a
the coefficient of the squared expression is 5
