____________________________________________________

Plug in 3 to x:

f(x) = 3³ - 7

Solve:

f(x) = 3³ - 7

f(x) = 3 · 3 · 3 - 7

f(x) = 9 · 3 - 7

f(x) = 27 - 7

f(x) = 20

What is the slope-intercept form for<br> y – 6 = 3 ( x− 1/3 )

Leviafan [203]

Answer:

y=3x+5

Step-by-step explanation:

This is th eanswer because slope intercept form is always y=mx+b.

So, if you simplify the right side of the equation, you then get

y-6=3x-1, I got that because 3 multiplied by -1/3, you get -1.

Then you add 6 to both sides to isolate y by itself. So, now you have

y=3x+5.

Hope this is helpful

In ΔQRS, the measure of ∠S=90°, the measure of ∠Q=83°, and RS = 7 feet. Find the length of SQ to the nearest tenth of a foot.

Simora [160]

Answer:

x ~0.9

Step-by-step explanation:

To solve for (x) in the given right triangle, use the trigonometric ratios, which are the following,

$sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}$

Each of the sides of a triangle is named with respect to the given angle. In this problem, one is given the side opposite to the given angle, and the side adjacent to it. Use the ratio of tangent (tan) to solve for the unknown side.

$tan(83)=\frac{7}{x}$

Manipulate the equation so that it is solved for (x),

$x=\frac{7}{tan(83)}$

x ~ 0.859

What is the sum of the factors of the trinomial x^2-6x+5

andrezito [222]

Its a binomial

$\\ \sf\longmapsto x^2-6x+5=0$

a=1
b=-6
c=5

If zeros be alpha and beta

$\\ \sf\longmapsto \alpha+\beta=\dfrac{-b}{a}$

$\\ \sf\longmapsto \alpha+\beta=\dfrac{-(-6)}{1}$

$\\ \sf\longmapsto \alpha+\beta=6$
