If f(x)=2x-1+3 and g(x)=5x-9, what is (f-g)(x)?

dangina [55]

Answer:

$\large\boxed{(f-g)(x)=-3x+11}$

Step-by-step explanation:

$(f-g)(x)=f(x)-g(x)\\\\f(x)=2x-1+3=2x+2\\g(x)=5x-9\\\\\text{Substitute:}\\\\(f-g)(x)=(2x+2)-(5x-9)\\\\=2x+2-5x-(-9)\\\\=2x+2-5x+9\qquad\text{combine like terms}\\\\=(2x-5x)+(2+9)\\\\=-3x+11$

The expression 8x2 − 64x + 720 is used to approximate a small town's population in thousands from 1998 to 2018, where x represen

mezya [45]

Answer:

$8(x-4)^{2}+592$

Step-by-step explanation:

we have

The expression $8x^{2} -64x+720$

This is a vertical parabola open upward

The vertex is a minimum

Convert the expression in vertex form

Factor the leading coefficient

$8(x^{2} -8x)+720$

Complete the square

$8(x^{2} -8x+16)+720-128$

$8(x^{2} -8x+16)+592$

Rewrite as perfect squares

$8(x-4)^{2}+592$

The vertex is the point (4,592)

That means -----> 4 years since 1998 the population has a minimum

Hey I need help solving this it's a test that will affect my grades, the question is in the picture.

Naddik [55]

Answer:

Step-by-step explanation:

Sole the power at the bottom, it gives .25

Multiple the whole fraction by 8 to make the denominator match 2

should be 8/2 + 1/2

They are the same denominator so you can add them to make 9/2

Divide it up/simple it up to make 4 and a half, or 4 1/2
