Answers

Answer 1

Answer:

Answer:

4y+6

Step-by-step explanation:

Perimeter is adding up the outside

so.. there are y+y = 2y

y+3 + y+3 = 2y+6

2y+6 + 2y = 4y+6

Hope this helps :)

If you wanted to use the numeric key pad to divide 100 by 2, you would type _____.2/100
100-2
100*2
100/2

Answers

For this case we have the following division:

$\frac {100} {2}$

We want to rewrite the problem in an equivalent way.

For this, we can use the following symbols that represent a division.

We have then:

$\frac {100} {2} =$ 100 ÷ 2

$\frac {100} {2} = 100/2$

Find the surface area of the prism.A. 1589 ft2
B. 9534 ft2
C. 811,551 ft2
D. 1,623,102 ft2

Answers

Simple...if this is a right rectangular prism..then you already know the formula for surface area...

Surface Area: 2(wl+hl+hw)

plug in what you know...

l=729

w=413

h=447

2((413)(729)+(447)(729)+(447)(413))

Surface Area≈1.62* $10^(6)$ (≈ symbol means it's approximate)

SA≈1,620,000

Thus, your answer, D.

What is the inverse of the function f(x)=1/9x+2

Answers

Answer:

$f^(-1)(x)=9x-18$

Step-by-step explanation:

we have

$f(x)=(1)/(9)x+2$

Let

$y=f(x)$

$y=(1)/(9)x+2$

Exchange variables x for y and y for x

$x=(1)/(9)y+2$

Isolate the variable y

$x-2=(1)/(9)y$

$y=9(x-2)$

$y=9x-18$

Let

$f^(-1)(x)=y$

$f^(-1)(x)=9x-18$ -------> inverse function

f(x) = 1/9x+2

-2 from both sides

f(x)-2 = 1/9x

*2 to both sides

9(f(x)-2) = x

replace 'f(x)' with 'x'

9(x-2) = f(x^-1)

simplify and reverse sides

f(x)^-1 = 9x-18

Answer: True

When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. When the two lines are parallel Corresponding Angles are equal.

Choose the missing step in the given solution to the inequality −6x − 10 > 14 + 2x. −6x − 10 > 14 + 2x _______________ −8x > 24 x < −3 −4x − 10 > 14 −8x − 10 > 14 −4x − 10 < 14 −8x − 10 < 1

Answers

If you would like to find the missing step, you can do this using the following steps:

- 6 * x - 10 > 14 + 2 * x
- 6 * x - 2 * x - 10 > 14
- 8 * x - 10 > 14
- 8 * x > 24 /(-8)
x < 24 / (-8)
x < - 3

The correct missing step would be - 8 * x - 10 > 14.

the missing answer is - 8 * x - 10 > 14.
