Solve the system. y = x^2 - 10x + 15 and y = -10

netineya [11]

Answer:

x=5, y=-10

Step-by-step explanation:

y = x²-10x+15 --- eqn 1

y = -10 --- eqn 2

Sub eqn 2 into eqn 1:

x²-10x+15 = -10

x²-10x+15+10 = 0

x²-10x+25 = 0

(x-5)² = 0

x-5 = 0

x = 5

HELP ME PLEAASSEEEEEE

luda_lava [24]

Answer:

see explanation

Step-by-step explanation:

(i)

to find h(g(x)) , substitute x = g(x) into h(x) , that is

h(g(x))

= h(2x - 3)

= 4(2x - 3)

= 8x - 12

(ii)

given

h(g(x)) = $\frac{1}{2}$ g(x) , then

8x - 12 = $\frac{1}{2}$ (2x - 3) ← multiply both sides by 2 to clear the fraction

16x - 24 = 2x - 3 ( subtract 2x from both sides )

14x - 24 = - 3 ( add 24 to both sides )

14x = 21 ( divide both sides by 14 )

x = $\frac{21}{14}$ = $\frac{3}{2}$ = 1.5
