Use elimination to solve the system below: 4x – 3y = 22 2x – y = 10

Answer:

Y = -2,  X = 4

Step-by-step explanation:

When you first use the elimination method, you would multiply 2x-y = 10 by -2 so that you could get the 4x to be eliminated.

4x-3y = 22

(2x-y = 10)-2 = -4x + 2y = -20

When you add those 2 together you are left with -y = 2, which you divide by negative to get y = -2. Then you substitute -2 for y to solve for x. I substituted the bottom equation

2x - (-2) = 10

2x +2 = 10

2x = 8

Divide both sides by 2 to get x = 4.

Answer:

Strong Negative

Step-by-step explanation:

We already know that the answer is between c and d because the correlation coefficient negative.

We just have to figure out whether it is strong or weak.

In general, anything between -.7 and -1 is considered to have a strong correlation. -.8 is in between -.7 and -1 therefore the correlation is best described as strong negative.

Find the value of x.<br> A) 55<br> B) 60<br> C) 70<br> D) 125
Anna11 [10]

Answer:

x = 70°

Step-by-step explanation:

The given triangle has 2 equal sides and is therefore isosceles.

The base angles are equal, both 55°

To find x subtract the sum of the 2 angles from 180

x = 180° - (55 + 55)° = 180° - 110° = 70°
