Answer:

{ x = -13, y = -4

Step-by-step explanation using elimination:

Solve the following system:

{x - 3 y = -1 | (equation 1)

{x - 2 y = -5 | (equation 2)

Subtract equation 1 from equation 2:

{x - 3 y = -1 | (equation 1)

{0 x+y = -4 | (equation 2)

Add 3 × (equation 2) to equation 1:

{x+0 y = -13 | (equation 1)

{0 x+y = -4 | (equation 2)

Collect results:

Answer: {x = -13 , y = -4

If the mean weight of 4 backfield members on the football team is 222 lb and the mean weight of the 7 other players is 198 lb, w

hoa [83]

To find the Mean or Average you have to add up all numbers it is asking for which in case are 222 and 198.

so you will add 222+198

That will equal 420

Then you will divide with the amount added together which is 2

420/2=210

so the mean of the 11 people is 210 or 210lbs

#1 Find the slope given the points (3,-20) and (5,8) *

Artyom0805 [142]

Hey there :)

To find the slope with two points we will need to use the equation $\frac{y^2-y^1}{x^2-x^1}$

$x^1$ $x^2$ $y^1$ $y^2$

( 3 , -20 ) ( 5 , 8 )

Here is what the equation should look like when replaced with the numbers (it will be a fraction) :

$\frac{8 - (-20)}{5 - 3}$

We know that two negatives cancel out and make a positive, so the numerator would actually be 8 + 20.

Solve the fraction and we get $\frac{28}{2}$

28 divided by 2 is 14. The slope is 14.
