Answer:

Step-by-step explanation:

624 students

Since they’re only 3 parts more girls then boys and the number equals 144, you just have to divide 144 by 3. You’ll get 48

Multiply 5 and 8 by 48 to get 240 and 384 and add to get 624 which is the answer

<h3>Answer:  8</h3>

Reason:

Replace p with 2 and evaluate.

p^3 = 2^3 = 2*2*2 = 8

Think of a cube that is 2 units along each side. It's volume is 2*2*2 = 8 cubic units. Repeated multiplication can be shortened to using exponents.

Another example: 7^4 = 7*7*7*7

Please help me! I’ll name you brainiest!!!
Kamila [148]

Answer:

80

Step-by-step explanation:

first, put in (5x-4) for the x in g(x).

g(f(x))=(5x-4)^2 -1

now, FOIL and simplify.

25x^2-40x+16-1

25x^2-40x+15

now, plug in -1 for x.

25(-1)^2-40(-1)+15

25+40+15

10. Rotate the figure shown 180° clockwise. Record the coordinates of the 3 points<br> image.
inna [77]

Answer:

J' = (6,7)

K' = (6,2)

L'=(3,7)

Step-by-step explanation:

From the attachment, we have:

J = (-6,-7)

K = (-6,-2)

L = (-3,-7)

Rotation: 180 degrees clockwise

Required

Find J', K' and L'

When a point (x, y)is rotated 180 degree clockwise, the resulting point is: (-x, -y)

So, we have:

J' = (6,7)

K' = (6,2)

L'=(3,7)

What is an equation of the line that passes through the point
Keith_Richards [23]

Answer:

5x - 4y = 32

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

5x - 4y = 36 ( subtract 5x from both sides )

- 4y = - 5x + 36 ( divide all terms by - 4 )

y = \frac{5}{4} x - 9 ← in slope- intercept form

with slope m = \frac{5}{4}

Parallel lines have equal slopes, thus

y = \frac{5}{4} x + c ← is the partial equation

To find c substitute (8, 2) into the partial equation

2 = 10 + c ⇒ c = 2 - 10 = - 8

y = \frac{5}{4} x - 8 ← in slope- intercept form

Multiply through by 4

4y = 5x - 32 ( subtract 4y from both sides )

0 = 5x - 4y - 32 ( add 32 to both sides )

32 = 5x - 4y, that is

5x - 4y = 32 ← in standard form
