The product of nine and a number is added to 6, the result is 24. What is the number?

Gina takes classes at both Westside Community College and Pinewood Community College. At Westside, class fees are $98 per credit

Kipish [7]

Answer: second option.

Step-by-step explanation:

Let be "w" the credit hours at Westside Gina is taking.

You know that class fees are $98 per credit hour at Westside, then the expression for the dollar amount she paid for her class fees at Westside is:

$98w$

Since she is taking a combined total of 13 credit hours at the two schools, the credit hours at Pinewood Gina is taking can be represented by this expression:

$13-w$

You know that class fees are $115 per credit hour at Pinewood, then the dollar amount she paid for her class fees at Pinewood can be expressed as:

$115(13-w)$

Therefore, the expression for the combined total dollar amount she paid for her class fees is:

$total\ paid=98w+115(13-w)\\\\total\ paid= -17w + 1495$

What is the standard form equation of the line shown below? Graph of a line going through negative 2, 3 and 1, negative 3

V125BC [204]

Answer:

3. 2x + y = −1

Step-by-step explanation:

To find the equation of the line, we write it first in the slope-intercept form:

$y=mx+q$

where

m is the slope

q is the y-intercept

From the graph, we see that the line crosses the y-axis at y = -1, so the y-intercept is -1:

$q=-1$

Now we have to find the slope, by calculating the rate of change of the line through 2 points:

$m=\frac{y_2-y_1}{x_2-x_1}$

Taking the two points at (-2,3) and (1,-3), we find:

$m=\frac{-3-3}{1-(-2)}=\frac{-6}{3}=-2$

So the equation of the line is

$y=-2x-1$

Now we have to re-arrange it in the standard form, so in the form

$ax+bx=c$

where a, b and c are integer numbers.

To do that, we simply add +2x on both sides of the equation of the line in the slope-intercept form, and we get:

$y+2x=-1$

So, option 3).

Use the slope-intercept form to Graph y=-1/8x+2

noname [10]

Step-by-step explanation:

This is a straight line equation. We only need two points to draw a straight line.

Choose two different numbers, put them into the equation instead of x, and calculate the value of y.

$y=-\dfrac{1}{8}x+2$

for x = 8

$y=-\dfrac{1}{8}\cdot8+2=-\dfrac{8}{8}+2=-1+2=1$

for x = -8

$y==-\dfrac{1}{8}\cdot(-8)+2=\dfrac{8}{8}+2=1+2=3$

Mark the points in the coordinate system and draw a straight line through the given points.
