Answer:

y=\frac{1}{3}+\frac{13}{3}

Step-by-step explanation:

We want to write the equation of a line that passes through (5, 6) and (-1, 4).

First, let's find our slope. We can use the slope formula:

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

Let's let (5, 6) be (x₁, y₁) and let's let (-1, 4) be (x₂, y₂). So, our slope is:

m=\frac{4-6}{-1-5}

Subtract:

m=-2/-6

Reduce:

m=1/3

So, our slope is 1/3.

Now, we can use the point-slope form, which is:

y-y_1=m(x-x_1)

For consistency, let's let (5, 6) be (x₁, y₁). We will also substitute 1/3 for m. So:

y-6=\frac{1}{3}(x-5)

Distribute:

y-6=\frac{1}{3}x-\frac{5}{3}

Add 6 to both sides:

y=\frac{1}{3}x-\frac{5}{3}+\frac{18}{3}

Add:

y=\frac{1}{3}+\frac{13}{3}

And we're done!

How do you solve 7(7a-9)>84
timama [110]

7(7a-9)>84

first multiple out to get rid of the parentheses

49a - 63 > 84

add 63 to both sides

49a > 147

Divide by 49 and flip the sign because when you divide a inequality you have to flip the sign

a < 3

A van travels 150 miles on 6 gallons of gas. How many gallons will it need to travel 325 miles?
shtirl [24]
<h3>Answer:  C) 13 gallons</h3>

============================================================

Work Shown:

(150 miles)/(6 gallons) = (325 miles)/(x gallons)

150/6 = 325/x

150*x = 6*325 .... see note below

150x = 1950

x = 1950/150 .... divide both sides by 150

x = 13 gallons is the final answer

-----------

Note: in this step, I cross multiplied. The general template for cross multiplication is that we go from A/B = C/D to A*D = B*C. As the name implies, the "cross" refers to the "X" shape that forms when you multiply the terms.
