evaluate f(6) when f(x) = 2x + 4

Answer:

y = (19 - x) / -9

Step-by-step explanation:

Subtract x from both sides.

-9y = 19 - x

Divide both sides by -9

y = (19 - x) / -9

Answer:

g (f(2)) = 3

Step-by-step explanation:

f (x) = x2 – 4

g(x) = x + 3

g (f (2)) =?

Find f(2) first

f (x) = x2 – 4

f (2) = 2^2- 4

= 0

Now put this in your g(x)

g(x) = x + 3

g (f(2)) = (f(2)) + 3

And u alredy know f(2) =0, so just put it in

g (f(2)) = 0 + 3

=3

Answer:

x = 3, PQ = 6 , PR = 12

Step-by-step explanation:

Given Q is the midpoint of PR , then

PQ = QR = 2x

PR = PQ + QR , that is

8x - 12 = 2x + 2x

8x - 12 = 4x ( subtract 4x from both sides )

4x - 12 = 0 ( add 12 to both sides )

4x = 12 ( divide both sides by 4 )

x = 3

Then

PQ = 2x = 2 × 3 = 6

PR = 8x - 12 = 8(3) - 12 = 24 - 12 = 12

The 1st graph shows a radical expression, where:

to find the inverse, replace f(x) with y, switch the x and the y, then solve for y

The only graph showing exponential growth is the 2nd graph (note how at 1 it's 1, at 2 it's 4, at 3 it will be 9, etc.)

Answer:

distance between (3,7) and (-6,-4) is [tex]\sqrt{202}[/tex]

Step-by-step explanation:

3rd point = (3, -4)

from (3,7) to (3, -4) is 11 units

from (-6,-4) to (3, -4) is 9 unites

hypothenuse

a^2 + b^2 = c^2

(11)^2 + (9)^2 = c^2

121 + 81 = c^2

c^2 = 202

c = [tex]\sqrt{202}[/tex]

x = -15

Step-by-step explanation:

1) Four times sum of a number and 10

4(x + 10)

2) is equal to 100 added to 8 times the number

4(x+10) = 8x + 100

x + 10 = 2x + 25

-15 = x

Answer:

36°

Step-by-step explanation:

a° = b°

2x+26 = 3x+21

x=5

thus a = 2(5)+26 = 36°

Answer:

12 or 10 blocks of clay

Step-by-step explanation:

If this is correct please give me brainliest.

Hyla needs 30 blocks of clay to cover the bottom of the box with a 2-centimeter-tall layer of clay.

Area is a measure of the size of a two-dimensional surface or region. It is the amount of space inside a shape, usually measured in square units, such as square meters or square feet.

The area is an important concept in geometry and is used in many fields, including physics, engineering, and architecture, among others.

The solution to this question is:

The area of the bottom of the box is:

24 cm x 20 cm = 480 cm^2

Since the layer of clay needs to be 2 cm tall, the volume of clay needed to cover the bottom of the box is:

480 cm^2 x 2 cm = 960 cm^3

Each block of clay has a volume of:

4 cm x 4 cm x 2 cm = 32 cm^3

So, to find how many blocks of clay Hyla needs, we can divide the volume of clay needed by the volume of each block:

960 cm^3 ÷ 32 cm^3/block = 30 blocks of clay

Therefore, Hyla needs 30 blocks of clay to cover the bottom of the box with a 2-centimeter-tall layer of clay.

Answer:

x = 6

Step-by-step explanation:

If PQ = 3x + 14, QR = 7x - 10, and Q is the midpoint of PR, then PQ = QR.

[tex]PQ = 3x + 14 = QR = 7x - 10\\3x + 14 = 7x - 10\\3x + 24 = 7x\\24 = 4x\\6 = x\\x = 6[/tex]

Answer:

2) Right angles always equal 90°

3) m∠F = 90° and m∠G = 90° which means they have the same angle measure.

4) Removing the m and replacing with the congruent symbol.

I'm not too sure how this goes but it should be something like that.

Answer:

A. P/2 - L = W

B. 9/5C + 32 = F

Step-by-step explanation:

A. P = 2L + 2W

P = 2(L+W)

P/2 = L + W

(P/2)-L = W

B. C = 5/9(F - 32)

9/5C = F - 32

9/5C + 32 = F
