Slope = -4, passing through (7, 4)

Answers

I am guessing you want the equation, so here we go.
the equation of a line is:
y = mx + c
To find c, plug in the given
y = 4
x = 7
m = -4

4 = -4(7) + c
4 = - 28 + c
take -28 to the other side
4 = -28 + c
+28 +28
32 = c

equation of this line:
y = -4x + 32

Mrs. Bergstedt teaches six classes. In her first period class she has 19 students, her third period she has 13 students, her fourth period 19 students, her fifth period 9 students, her sixth period 14 students, and her seventh period 15 students. What is her average class size, to the nearest tenth

Answers

19 + 13 + 19 + 9 + 14 + 15

19 + 13 = 32
32 + 19 = 51
51 + 9 = 60
60 + 14 = 74
74 + 15 = 89

89 / 6 (the number of classes she has)
= 14.8

Which is the graph of y = |3x| - 2?

Answers

Answer: the third graph

Step-by-step explanation:

Ok so one way to do this is by plugging in points which is long but easiest. So since it’s the absolute value, whenever it passes the y- axis to the negative side, it will go up. So we know it’s either the third or last. The y intercept is -2, and the graph with that is the third.

Answer:

The third option.

Step-by-step explanation:

The formula for a volume of a cylinder is V= pi r squared h/3. solve the equation for h, or height. PLZ help ASAP

Answers

Answer:

h=3V/πr²

Step-by-step explanation:

V= πr²h/3
πr²h=3V
h=3V/πr²

Answer:

3V / (pi r^2) = h

Step-by-step explanation:

V= pi r squared h/3

Multiply each side by 3

3V = pi r^2 h /3 * 3

3V = pi r^2 h

Divide each side by pi r^2

3V / (pi r^2) = pi r^2 h /( pi r^2)

3V / (pi r^2) = h
