Answer:

23+5x

Step-by-step explanation:

Group like terms(Numbers and variables)-

5+3+7+8+x+2x+x+x

Add the like terms-

23+5x

Answer:

Step-by-step explanation:

To find the equation of the line given the slope and a point we use the formula

[tex]y - y_{1} = m(x - x_{1})[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the slope is 8 and the point is ( - 9 , - 7)

Substitute the values into the above formula and solve for the equation

We have

[tex]y + 7 = 8(x + 9) \\ y + 7 = 9x + 72 \\ y = 9x + 72 - 7[/tex]

We have the final answer as

Answer:

All statements are true, but if you try to reverse them they won't necessarily be true.

Let's try:

Square ⇒ Has 4 sides

But if something has 4 sides it doesn't mean it's a square (example: rectangle)

Angle is 80° ⇒ acute angle

But acute angle is any angle below 90°, not just 80° so the reverse isn't true.

x – 17 = 4 ⇒ x = 21

And if we reverse

x = 21 ⇒ x – 17 = 4

we see that it's true for either direction.

x = 7 ⇒ |x| = 7

But |x| = 7 doesn't mean that x has to be 7, x can also be -7, so the reverse isn't true.

x – 17 = 4, then x = 21

Answer:

A) [tex]5^3*5^{-4}=5^{3-4}=5^{-1}=\frac{1}{5}[/tex] (Yes. It has a value between zero and one.)

B) [tex]\frac{3^5}{3^{-6}}=3^{5-\left(-6\right)}=3^{5+6}=3^{11}=177147[/tex] (No. It does not have a value between zero and one.)

C) [tex]\left(\frac{1}{4}\right)^3* \left(\frac{1}{4}\right)^2=\left(\frac{1}{4}\right)^{3+2}=\left(\frac{1}{4}\right)^5=\frac{1^5}{4^5}=\frac{1}{1024}[/tex]. (Yes. It has a value between zero and one.)

D) [tex]\frac{\left(-7\right)^5}{\left(-7\right)^7}=\left(-7\right)^{5-7}=\left(-7\right)^{-2}=\frac{1}{\left(-7\right)^2}=\frac{1}{49}[/tex] (Yes. It has a value between zero and one.)

Answer:

see below

Step-by-step explanation:

A.  5^3 * 5^-4 = 1/5

It has value between  0 and 1

B. 3^5 / 3^-6 = 177147

It doesn't have a value between 0 and 1

C. (1/4)^3 * (1/4)^2 = 1 / 1024

It has value between  0 and 1

D. (-7)^5 / (-7)^7 = 1/49

It has value between  0 and 1

(f o g) (x) means that we substitute 3/x into x for f(x)

2 / ((3/x) - 1)

We have to get rid of  the fraction in the denominator. Multiply both the top and bottom by x

(f o g) (x) = [tex]\frac{2x}{3 - x}[/tex]. This is as simplified as it can get.

Answer:

the surface  area of a penny = 662.81 mm²

Step-by-step explanation:

given:

A penny is a cylinder with a diameter of 19.05 millimeters

and a thickness of 1.55 millimeters.

find:

what is the surface  area of a penny?

surface area of a cylinder formula:

As = 2 π r h + 2 π r²

let r = 19.05 / 2

r = 9.53 mm

let h = 1.55mm

plugin values into the formula:

As = 2 π (9.53) 1.55    +    2 π (9.53)²

As = 92.76 +  570.05

As = 662.81 mm²

therefore,

the surface  area of a penny = 662.81 mm²

Answer:

the surface  area of a penny = 662.81 mm²

Answer:

$3.05 i'm pretty sure

Step-by-step explanation:

If one pound is $0.94 and she bought 3.25 pounds you multiply 3 by 0.94 and get $2.82 (we multiply by 3 to make it easier and to deal with the .25 later) then now we deal with the .25, since .25 is 1/4 in fraction just find out what 1/4 of .94 is which is .23 cents. So add $2.82 and $0.23 and you get $3.05

Step-by-step explanation:

t = teaspoons

c = cup

b = tablespOON

T = B x 3

( teaspoons ) 48 = ( tablespoons ) 16 x ( for each tablespoon there is 3 teaspoons ) 3

for every one tablespoon, there are 3 teaspoons which equal how many cups there are.

48 TEASPOONS

16 TABLESPOONS

1 CUP

Answer:

I'm not sure what you mean by opposite, but by all means the opposite of 0.93 would be -0.93 as it's the negative value of that decimal.

Answer:

Yes, 9.52 is less than 90.13

Step-by-step explanation:

Because 90 is a whole number from the decimal 90.13, and 9 is the whole number from the decimal 9.52

Compare 90 and 9. 90 is greater; therefore, 9.52 is less than 90.13

Answer:

A. x-4y=8

Step-by-step explanation:

Slope = [tex]\frac{1}{4}[/tex]

y-intercept = -2

In y=mx+b

m = slope

b = y-intercept

Just replace m with 1/4 and b  with -2

[tex]y = \frac{1}{4} x -2\\[/tex]

Multiply through by 4 and re-arrange

[tex]4(y=\frac{1}{4} x -2)\\\\4y =x -8\\0 =-4y +x-8\\8 =-4y+x\\\\x -4y =8[/tex]
