Answer:

x = 2, y = -2

Step-by-step explanation:

This means that $-3x + 4 = 4x - 10$

Now, you just have to solve the equation

$-3x + 4 = 4x - 10\\\\$

add 3x to both sides

$4 = 7x - 10$

add 10 to both sides

$14 = 7x$

divide both sides by 7

$x = 2$

Substitute this into the equation $y = -3x + 4$

$y = -3(2) +4\\y = -6 + 4$

$y = -2\\$

I just need a quick answer please help me?

Feliz [49]

Answer:

x = 2.

y = 6.

Step-by-step explanation:

Consider the triangle on the left.

Because there are 2 equal angles at the vertex on the bottom right:

3/9 = x/(8 - x)

1/3 = x / (8 - x)

3x = 8 - x

4x = 8

x = 2 (answer).

Similarly, for the second triangle:

3/y = 2/4

3/y = 1/2

y = 6

(answer).

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

nordsb [41]

Answer:

Note: The full question is attached as picture below

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.
