Hello here is a solution :
<span>h(g(f(x))) ?
</span>g(f(x))= g(2x+5)=(2x+5)²=(2x)²+2(2x)(5)+5² = 4x²+20x+25
h(g(f(x)))(x) = h(4x²+20x+25) = -2(4x²+20x+25)
h(g(f(x)))(x) = -8x²-40x-50
Answer:
50%
Step-by-step explanation:
10+4+2+4=20
10/20=0.5
Answer:
38
Step-by-step explanation:
30 = X-8
+8 +8
38=x
The correct choice is the first one
X=2y-6
Let's solve for y.
<span>x=<span><span>2y</span>−6
</span></span>Step 1: Flip the equation.
<span><span><span>2y</span>−6</span>=x
</span>Step 2: Add 6 to both sides.
<span><span><span><span>2y</span>−6</span>+6</span>=<span>x+6
</span></span><span><span>2y</span>=<span>x+6
</span></span>Step 3: Divide both sides by 2.
<span><span><span>2y/</span>2</span>=<span><span>x+6/</span>2
</span></span><span>y=<span><span><span>12</span>x</span>+3
</span></span>Answer: y=12x+3
