Write an equation in slope intercept form for the line with slope negative three fourths and y intercept of negative one

Stells [14]

The slope intercept form is $y=-\frac{-3x}{4}-1$ .

Solution:

Given data: slope = $-\frac{3}{4}$ and y-intercept = –1

y-intercept means (x, y) = (0, –1)

Equation of a line for slope intercept form: $y-y_1=m(x-x_1)$

Here, $x_1=0, y_1=-1$ and $m=-\frac{3}{4}$ .

⇒ $y-(-1)=\frac{-3}{4} (x-0)$

⇒ $y+1=\frac{-3}{4} (x)$

Do cross multiplication.

⇒ $4(y+1)=-3x$

⇒ $4y+4=-3x$

⇒ $4y=-3x-4$

Divide both sides of the equation by 4.

⇒ $y=-\frac{-3x}{4}-\frac{4}{4}$

⇒ $y=-\frac{-3x}{4}-1$

Hence the slope intercept form is $y=-\frac{-3x}{4}-1$ .

What is the surface area of a cylinder with the given dimensions?

pogonyaev

Answer:

The surface area of a cylinder with the given dimensions is 571.48 $cm^2$ .

Step-by-step explanation:

To find the surface area, you need to use the formula $2\pi r^2 + h * 2\pi r$ where $r$ represents the radius and $h$ represents the height. In this problem, the expression would be $7^2 * 3.14 * 2 + 3.14*14*6$ = $49 * 6.28 + 3.14 * 84$ = $307.72+263.76$ = 571.48 $cm^2$ .

Find f(x) and g(x) so that the function can be described as y = f(g(x)).

GenaCL600 [577]

You could make this super easy by letting g(x) = $x^{2} +2$ and f(x) = $\frac{9}{x}$ and then the composition would be to take g(x) and put it into the x in f(x) to give you your $\frac{9}{ x^{2} +2}$

Answer:

Step-by-step explanation:

E=9x-38

F=2x+40

9x+2x+2=90

11x=90-2

11x=88

x=88/11=8

F=2*8+40

16+40

=56
