Write an equation for a line that is parallel to the graph of 14x-7y=8 that passing through the point at (-2,5)

1 answer:

6 0

Parallel means they have the same slope
find the slope
14x - 7y = 8
subtract 14x from both sides
-7y = -14x + 8
divide both sides by -7
y = 2x -8/7

y = mx + b
m is slope
b is y-intercept

We found that the slope is 2
y = 2x + b
to find the y-intercept, plug in the given point
5 = 2(-2) + b
5 = -4 + b
add 4 to both sides
9 = b

The equation
y = 2x + 9

Rewrite to standard form
subtract 9 from both sides
y - 9 = 2x
subtract y from both sides
and rotate the equation
2x - y = -9

Hope this helps

It takes 0.5 gallon of cream to make 1 pound of butter. How much cream would you need to make 2.5 pounds of butter?

Natasha_Volkova [10]

1.25 gallons

so we know 0.5 gallons makes 1 pound, and we know that there are at least 2 pounds of butter made.

so we know that there is 1 full gallon of cream used.

however, there is also .5 pounds of butter, so we need to find out the other half.

to do this, we need to split the .5 gallons of cream in half, making 0.25

then, we add 1 + 0.25 gallons to equal 1.25 gallons of cream needed to make 2.5 pounds of butter

Express 48 as a fraction of 60.

Virty [35]

Hello @14mullinsalf,

How are you doing? So, automatically, we put the fraction $\frac{48}{60}$

After that, you may want to simplify the answer.
Find the GCD (or HCF) of numerator and denominator
GCD of 48 and 60 is 12

Divide both the numerator and denominator by the GCD
 $\frac{48/12}{60/12}$

Your answer is $\frac{4}{5}$

I hope I helped, and contact me if you need further assistance.

Thank you,
Darian D.
