Which is an equation of the line that passes through the points (-6,-8) and (4,-4)

natita [175]

Answer:

y= $\frac{2}{5}$ x-6.5

Step-by-step explanation:

$\frac{(-8)-(-4)}{(-6)-4} \\$ = $\frac{-4}{-10}$ = $\frac{2}{5\\}$

y=mx+b

-8 = ( $\frac{2}{5}$ ) (-6) +b

-8 = - $\frac{12}{8}$ +b

b= -6.5

Zoey made 6 1/2 cups of trail mix for a camping trip. She wants to divide the trail mix into 3/4 cup of servings. Twelve people

AlekseyPX

Answer:

Step-by-step explanation:

Given that:

Total number of cups of trail mix available for camping trip = $6\frac{1}{2}$

Amount of one serving contains = $\frac{3}{4}$ cups

Number of people at the trip = 12

To find:

Whether each person will be able to get the servings?

Solution:

Here, we can find the total number of servings by dividing the total number of cups of trail mix with the amount of one serving.

First of all, let us convert the mixed fraction into fractional number.

$6\dfrac{1}{2} = \dfrac{6\times 2+1}{2} = \dfrac{13}{2}$

Therefore, total number of servings available as per the given quantities:

$\dfrac{\frac{13}2}{\frac{3}4}\\\Rightarrow \dfrac{13\times 4}{2\times 3} \\\Rightarrow \dfrac{26}{3}\\\Rightarrow \approx 8$

So, With this type of servings Zoey will be able to serve only 8 people.

Therefore, there is not enough servings.

I think they just want you to follow the graph like F goes on -3,2 and then when you do it you rotate it 90 degrees. And then just do the other ones yk?

Please help this is the last question and determines wether I pass or not

givi [52]

Hopefully I’m not too late, but here’s how I solved it. Basically, replace F with 68. Subtract 32 from both sides so your equation becomes 9/5C=36. Divide both sides by 9/5 so C is left but itself (C=36/1.8). The answer should come out to 20. If you want to check my answer, plug 20 into the equation. Multiply 20x9/5 which equals 36. Add 36 and 32 together to get 68. Hope this helps
