Please help me with this problem:)
krok68 [10]

Answer:

(2,1)

Step-by-step explanation:

3x+y = 7

-2x +y = -3

Solve the second equation for y by adding 2x to each side

-2x+2x +y = -3+2x

y = -3 +2x

Substitute into the first equation

3x+ (-3+2x) = 7

Combine like terms

5x -3 = 7

Add 3 to each side

5x-3+3 = 7+3

5x = 10

Divide by 5

5x/5 = 10/5

x=2

Now we need to solve for y

y = -3 +2x

y = -3 +2(2)

y = -3+4

y =1

The residual for Raisin Bran is 8.556. How many grams of sugar does Raisin Bran actually have per cup
nordsb [41]

Answer:

Note: <em>The full question is attached as picture below</em>

a. Slope of 0.536 means that when there is an increase in carbohydrate content, there will be sn increase in 0.536 grams of sugar content.

b. Coefficient of Determination, R^(2) = 0.544^(2) = 0.295936 = 0.296. Percent of variation = 29.6

c. For carbohydrate content of 29 grams,

Predicted amount of sugar per cup for Raisin Bran = -5.10 + 0.536*29 = 10.444 gram

d. Residual value= Actual value - Predicted value

8.556 = Actual sugar content - 10.444

Actual sugar content = 8.556 +10.444

Actual sugar content = 19

So, the Raisin Bran actually have 19 grams of sugar per cup.

dem82 [27]
(x² + 4x - 45)/(x² + 10x + 9) 
<span>
Numerator = N = x² + 4x - 45 </span>
= x² + 9x - 5x - 45 
= (x² + 9x) - (5x + 45) 
= x(x + 9) - 5(x + 9) 
= (x + 9)(x - 5) 
<span>
Denominator = D = x² + 10x + 9 </span>
= x² + x + 9x + 9 
= (x² + x) + (9x + 9)
