Answer: -2/3

Step-by-step explanation:

If you want to find the slope of something, the quick way is to use \frac{rise}{run}.

In this situation, the “rise” (change in y axis) is -2 because it’s going down and the “run” (change in x axis) is 3. Therefore, it’s -2/3.

The formula to find slope is:

\frac{y_{2}-y_{1}}{x_{2}-x_{1} }

(I think, if I memorized it correctly)

Answer:

Step-by-step explanation:

Tito wants to buy some peanut butter to donate as much as possible.

There some brands are given with their price.

we will calculate the price of per ounce peanut butter of each brand.

A. Nutty : 12 ounces for $2.19

cost per ounce =

                        = $0.1825 ≈ $0.18 per ounce

B. Grandma's : 18 ounces for $2.79

cost per ounce =

                        = $0.155 ≈ $0.16 per ounce

C. Bee's : 0.28 ounces for $4.69

cost per ounce =

                        = $16.75 per ounce

D. Save-A-Lot : 40 ounces for $6.60

cost per ounce =

                        = $0.165 ≈ $0.17 per ounce

The lowest price is $0.16 per ounce. So he should buy Grandma's peanut butter.

Answer:

Angle BCA = 70

Angle CAB = 20

Step-by-step explanation:

Not sure what angle you meant, so I'll give you all of them <3

Angle BCA = 70 degrees, because If two angles form a line, they add up to 180.  (110+x=180, x = 70)

Angle CAB = 20 degrees, because there are 180 degrees in a triangle, so 90+70+x=180, x = 20

Hope it helps <3
