Hello :
<span>f(x)=x²+4x-5
</span><span>The axis of symmetry for a function in the form f(x)=x^2+4x-5 is x=-2 :
</span>f(x) = (x+2)² + b
f(x) x²+4x+4+b= x² +4x-5
4+b= -5
b = -9
the vertex is : (2 , -9)
Greetings! Hope this helps!

Answer:
Answer=B
(f+g)(x)=-3x-5
Step-by-step explanation:
f(x)=x+8.
g(x)=-4x-3.
(f+g)(x) means f(x)+g(x),So
(x+8)+(-4x-3)
(add all same terms together)
=(x+(-4x))+(8+(-3))
=-3x+5
so,
(f+g)(x)=-3x+5
The total amount of paint needed is 15 quart and it cost $41.25.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
0.0015 quart of paint to cover 1 square inch.
Let the area of the rectangle be 10000 in², hence:
Amount of paint = 0.0015 quart per in² * 1000 in² = 15 quart
Cost of paint = $2.75 per quart * 15 quart = $41.25
The total amount of paint needed is 15 quart and it cost $41.25.
