Solve for y. Then find the values of y that correspond
julsineya [31]

7.

y + 8x = -2

f(x) = y = -8x - 2

f(0)=-2, f(1)=-10, f(2)=-18, f(-2)=14

8.

12x + 3y = 15

3y = -12x + 15

f(x) = y = -4x + 5

f(-1)=9, f(0)=5, f(1)=1

9.

y - 3x = 9

f(x) = y = 3x + 9

f(-2)=3, f(0)=9, f(2)=15

10.

0.4y + 2x = 1.2

4y + 20x = 12

4y = -20x + 12

f(x) = y = -5x + 3

f(-3) = 18, f(0)=3

Simone claims that the slope of the line through (-2, 7) and (3, 0) is the same as the slope of the line through (2, 1) and (12,
JulijaS [17]

Answer:

Simone is correct

Step-by-step explanation:

Given

Line 1:

(x_1,y_1) = (-2, 7)

(x_2,y_2) = (3, 0)

Line 2:

(x_1,y_1) = (2, 1)

(x_2,y_2) =(12, -13)

Required

Is Simone correct?

Slope (m) is calculated using:

m = \frac{y_2 - y_1}{x_2 - x_1}

For Line 1

m = \frac{0 - 7}{3 - (-2)}

m = \frac{0 - 7}{3 +2}

m = \frac{-7}{5}

m = -\frac{7}{5}

For Line 2:

m = \frac{-13 - 1}{12 -2}

m = \frac{-14}{10}

Divide by 2/2

m = \frac{-14/2}{10/2}

m = \frac{-7}{5}

m = -\frac{7}{5}

By comparison, both lines have the same slope.

Hence, Simone is correct

"More than 60% of the students scored below the mean on the last test." Can this statement be true? Why or why not?
Lelu [443]
The mean is the average of a set of numbers.

So if the remaining 40% of students score 100 points, and the 60% score like 50 points, then the mean would still be 70 points because of the 40% of students that scored super high.

So yes, it can be true.

Answer:

-94%, -0.925, -9/10, -8/9

Step-by-step explanation:

-94% = -0.94

-8/9 = -0.89

-9/10 = -0.90

Since the values are negative the order is opposite then if they were all positive.
