Step-by-step explanation:

I do not fully understand your question yet

assuming this is what you asked

f(x) = 3x-1 and g(x) = x² +1

f o g(7) = f( g(7)) = f( 7² +1) = f( 50) = 3*50 -1 = 149

(f o g) (7) = f(g(x))(7) = f( x²+1)(7) = ( 3x²+3-1) (7) = (3x²+2)(7) ...

4x - 12 = 16) 4x -12 + 12 = 16 + 12) 4x = 28) 4x/4 =28/4) x = 7

Answer:

x=7

Step-by-step explanation:

You multiply the 2 with what is inside of the parenthesis so 3x-12

x+3x-12=16

then you add x +3x =4x

4x-12=16

then you add 12 to both sides

4x=28

then you divide by 4 on both sides

x=7

Answer:

do u mean the degree? if u do then it would be 60

Step-by-step explanation:

Answer: 25pi/3 square units

=============================================================

Explanation:

If that point is the center, then we have two pizza slices that sweep out 60 degrees of a central angle.

The full circle has pi*r^2 = pi*5^2 = 25pi square units of area

We only want 60/360 = 1/6 of that for each slice, so 2*(1/6) = 1/3 of the full circle area is shown by the shaded region

(1/3)*(full circle area) = (1/3)*25pi = 25pi/3 square units is the shaded area

Answer:

85 degrees

Step-by-step explanation:

since all angles in a parallelogram add up to 360 degrees, and we know that angles M and P are equal, we can double their measures to get 190 degrees. This leaves 170 degrees left to split evenly between angles L and N, making each one 85 degrees.

Find the Width of the Rectangular Prism.

Answers

Answer:

w = V/12 IN X= 840in then 840÷12 = 70in

A rectangular prism has 70in width having volume 840in³, length is 2in, and height 6in.

What is a rectangular prism?

A rectangular prism or a cuboid is a three-dimensional closed figure which has volume along with surface area.

The volume of a cuboid is the product of its length, width, and height.

V = (l×w×h).

The total surface area of a cuboid is 2( lw + wh + wl) and the lateral surface area is 2(l + w)×h.

Given, A rectangular prism has a volume 840 in³, its length is 2 in and its height is 6in.

Assuming width to be w in.

∴ (l×w×h) = volume.

(2×w×6) = 840.

12w = 840.

w = 70 in.

Louise buys 1 pack of pencils and 1 box of crayons for her son for $3.39. Elaine buys 7 packs of pencils and 8 boxes of crayons for her students for $25.88.

Answers

Answer:

Step-by-step explanation:

p+c=3.39, p=3.39-c

7p+8c=25.88, using p=3.39-c in this equation gives you

7(3.39-c)+8c=25.88

23.73-7c+8c=25.88

23.73+c=25.88

c=2.15, since p=3.39-c

p=3.39-2.15

p=1.24

So pencils cost $1.24 and crayons cost $2.15
