Use the work shown below to write the equation for a line that passes through the points (−5, 0) and (−1, −8).
Dennis_Churaev [7]

Answer:

M = -2

b = -10

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

m = (-8 -0)/(-1- -5)

   = (-8-0)/(-1+5)

    = -8/4

    = -2

We now want to find the y intercept

y = mx+b is the slope intercept form of the equation

y = -2x+b

Using the point (-5,0)

0 = -2(-5) +b

0 = 10+b

Subtract 10 from each side

-10 = 10-10+b

-10 =b

The y intercept is -10

y= -2x-10

There are 9 teachers and 5 aides at the Hills Elementary School. What is the ratio of teachers to all adults?​
nexus9112 [7]

Answer:

C. \frac{9}{14} , 9:14 , or 9 to 14

Step-by-step explanation:

With there being 9 teachers and 5 aides, the total number of adults is 14, leaving a fraction of \frac{9}{14} , 9 teachers and 14 adults. Checking to simplify, there are no shared values by 9 and 14, so it is in it's simplest form.

How to solve 4x-c=k solve for x
Tresset [83]

Answer:

x = \frac{k + c}{4}

Step-by-step explanation:

<em><u>Given:</u></em>

4x - c = k

<em><u>Solve for:</u></em>

x

<em><u>Solution:</u></em>

(1) Let's move all of components that do not contain x (our target) to the right side (notice the change of sign of c from negative to positive):

4x = k + c

(2) Let's divide both sides of equation by 4:

\frac{4x}{4}  = \frac{k + c}{4}

(3) Now, we simplify the left side:

x = \frac{k + c}{4}

This is the solution.

Hope this helps!

Use the FOIL method to evaluate the expression
In-s [12.5K]
So u multiply each term in the first parentheses by each term in the second parentheses.

√5 √5 + 6√5-3√5 - 3x6
Now you multiply the numbers which will get u:
5+6√5 - 3√5 - 18
Then subtract:
-13 +3√5 that’s your answer
