Help me with this math problem, I need someone to guide me through it I don’t understand what I’m supposed to do first
natita [175]

Answer:

see below

Step-by-step explanation:

The parent function is x^2 which is a parabola at vertex (0,0)

g(x) = ( x+3) ^2

y = f(x + C) C > 0 moves it left  

So the parabola is shifted to the left 3 units

h(x) = -( x+3) ^2

y = −f(x)  

Reflects it about x-axis

Means flip it about the x axis

What is the missing step in solving the inequality 5 – 8x < 2x + 3? Add 2x to both sides of the inequality. Subtract 8x from
kvasek [131]

Answer:

⇒ Add 8x to both sides of the inequality

⇒ x>1/5

Step-by-step explanation:

First, you subtract by 5 from both sides of equation.

5-8x-5<2x+3-5

Solve.

-8x<2x-2

Then subtract by 2x from both sides of equation.

-8x-2x<2x-2-2x

Solve.

-10x<-2

Multiply by -1 from both sides of equation.

(-10x)(-1)>(-2)(-1)

Solve.

10x>2

Divide by 10 from both sides of equation.

10x/10>2/10

Solve to find the answer.

2/10=10/2=5 2/2=1=1/5

x>1/5 is final answer.

Hope this helps!

Any one that knows this please help thanks!
yulyashka [42]

Replace the x with 9, and the y with 1.

(x · y²)/-5 becomes (9 · 1²)/-5

1² is just 1, so you're doing 9 × 1 (which is = 9) over -5.

Therefore, your final answer is -9/5.
