Pls help!! if f(x) = 2x^2-4x and g(x)=5-2x, evaluate f(x) - g(x) for x=5

1 answer:

7 0

Answer is C=35

How? Plug 5 into all the x's and solve for both g(x) and f(x) then finish off by subtracting f(x) from g(x).

Emily, Frances, and Bill each carried a 10-pound bag of soil into the backyard. After putting the soil in the first flower bed,

Art [367]

Step-by-step explanation:

emily: 10(5/8) = 6 1/4 or 6.25 pounds left

10- 6.25 = 3.75 used

Frances : 10(2/5) = 4 pounds left

10-4 = 6 pounds used

Bills : 10(2/5) = 4 pounds left

10-4 = 6 pounds used

add them together

15.75 or 15 3/4 pounds of soil in the first flower bed

I need step by step help with: 3x^1/3 + 2x^2/3 =5

Luba_88 [7]

If you write $y=x^{1/3}$ , you'll notice this is really just a quadratic equation that can be factorized:

$2x^{2/3}+3x^{1/3}-5=0\iff 2y^2+3y-5=0\iff (2y+5)(y-1)=0\iff(2x^{1/3}+5)(x^{1/3}-1)=0$

So you have

$2x^{1/3}+5=0\implies 2x^{1/3}=-5\implies x^{1/3}=-\dfrac52\implies x=-\dfrac{125}8$

and

$x^{1/3}-1=0\implies x^{1/3}=1\implies x=1$
