(-5,7) and (2,5) <br> find the slope of the line passing through the given points

svp [43]

Answer: -2/7

Step-by-step explanation:

To find the slope, you use the formula $m=\frac{y_2-y_1}{x_2-x_1}$ .

$m=\frac{5-7}{2-(-5)} =\frac{-2}{7}=-\frac{2}{7}$

Now, we know the slope is -2/7.

2(3x - 4) = 2x + 12

6x - 8 = 2x + 12

4x = 20

x = 5

AB = 3(5) - 4 = 11

AC = 2(5) + 12 = 22

BC = 7(5) - 2 = 35 - 2 = 33

AC:BC = 22:33 = 2:3

Explain how you would get the answer please

kompoz [17]

To find the intersection points, you take x^2 - 4x + 9 = -2x + 17

This gives x^2 - 2x - 8 = 0,

which factorises to (x - 4)(x + 2) = 0, giving the solutions x = 4 or x = -2

From the graph, we can see that x is positive, meaning x = 4, so a = 4.

Substituting x = 4 into y = -2x + 17, we get y = -2(4) + 17 = 9, so b = 9.

a + b = 4 + 9 = 13. The answer is B.

wolverine [178]

Answer:

15 3/4

Yes

Step-by-step explanation:

Given that :

8 boxes = 16 1/4 cups

Required cup of concentrated juice per day = 2 1/4 cups

Total cups that will be required for the entire 7 days :

Number of cups per day * number of days

2 1/4 * 7

= 15 3/4 cups

Since 8 boxes = 16 1/4 ; then 8 boxes will be enough
