Answer:

x= -300

Step-by-step explanation:

0.25x+7 = 1/5x-8

convert the decimal into a fraction

1/4x+7 = 1/5x-8

1/4x+7+8 = 1/5x

1/4+15 = 1/5x

multiply both sides of the equation by 20

1/4x(20)+15(20) = 1/5x(20)

5x+300 = 4x

5x-4x+300 = 0

x+300 = 0

x = -300

Step-by-step explanation:

Answer:

Both Bobby's and Lisa's points are on the line.

Step-by-step explanation:

You just have to plug the points into the equation.

Bobby:

(4,2)

2 = 5(4) - 18

2 = 20 - 18

2 = 2

Lisa:

(3,-3)

-3 = 5(3) - 18

-3 = 15 - 18

-3 = -3

So they both are correct.

Answer:

let the length of each of the 2 equal sides= n

then n+n+(n-5)=49

3n=44

n=44/3

Answer:

let the length of each of the 2 equal sides= n

then n+n+(n-5)=49

3n=44

n=44/3

Answer:

Phone B

Step-by-step explanation:

It is around the same cost as Phone C, but has unlimited data (which means unlimited gigs)

Answer:

B

Step-by-step explanation:

Charge of 9 gigs for A

find slope:

125 - 95/5 - 3 = 30/2 = $15/month

use point slope form with point (3,95) and slope 15:

y - y1 = m(x - x1)

y - 95 = 15(x - 3)

y - 95 = 15x - 45

 + 95           +95

y = 15x + 50

put 9 for x, gigs, in the new equation:

y = 15(9) + 50

y = 135 + 50

y = 185

$185 for opt A

Charge of 9 gigs for B

slope = 0

there is the fee of 150 so the equation is:

y = 0x + 150

Next find the price for 9 gigs

y = 9(0) + 150

y = 150

$150 for opt B

Charge of 9 gigs for C

use graph and the cost is about $157

A: $185

B: $150

C: $157

Answer:

the answer is d add 8x to both sides

Step-by-step explanation:

The missing step in step 2 is to add 8x to both sides of the inequality.

An inequality shows the relationship between two mathematical expressions which is denoted by the inequality signs such as (<, >, ≤, ≥).

The inequality given is expressed as:

5 - 8x < 2x + 3

5 - 8x - 3 < 2x + 3 - 3

2 - 8x  < 2x

So, we need to add + 8x to both sides, in order to eradicate the variable (8x) from the left-hand side.

i.e.

2 - 8x + 8x < 2x + 8x

2 < 10x

In step 3, we divide both sides by the coefficient of x.

i.e.

ΔABC ≅ ΔQPR

Step-by-step explanation:

if you were to reflect it, they would line up also A ≅ Q because their angles are the same and I know that because of the markings, they both have one arc and B and P both have two arcs meaning they are congruent and C and R both have three arcs so they are congruent.

Answer:

u = 24

Step-by-step explanation:

[tex]\frac{u}{4}[/tex] + 12 = 18

   -12    -12

[tex]4*\frac{u}{4}[/tex] = 6*4

u = 24

Answer:

u = 24

Step-by-step explanation:

Original Equation:

u/4 + 12 = 18

Subtract 12 from both sides

u/4 = 6

To separate the u from the 4, multiply both sides by 4

u = 24

Answer:

95 ° 36 ′ 36 ′′

Step-by-step explanation:

To convert 95.61 into degrees, minutes and seconds, you'll have to leave the whole units of degrees alone. You have to multiply the decimal by 60. The whole number becomes the minutes.

Then, you multiply 0.61 by 60, in which you get 36.6.

Take the remaining decimal and multiply by  60  and take the whole number portion to find the seconds.

Multiply 0.6 by 60. You get 36.

And lastly, Take the three sets of whole numbers and combine them, using the symbols for degrees ( ° )  , minutes  ( ′ ) , and seconds  ( ′′ ) .

This is how you get 95 ° 36 ′ 36 ′′.

Answer:

y = 5/2x + 1/2

Step-by-step explanation:

Find the slope with the formula [ y2-y1/x2-x1 ].

-2-3/1-(-1)

-5/2

undefined

Find the y-intercept using the formula for slope-intercept form [ y = mx + b ]

y = -5/2x + b

3 = -5/2(-1) + b

3 = 5/2 + b

1/2 = b

Put everything we solved for into its final form.

y = 5/2x + 1/2

Best of Luck!

Answer:

y = -2.5x + 0.5

Step-by-step explanation:

First we must find the slope.

To do so we will use this formula:

y2 - y1 / x2 - x1

Substitute with (-1, 3) and (1, -2)

-2 - 3 / 1 + 1

-5/2

-2.5 is our slope.

Now to put this into slope-intercept form we will use Point-slope formula.

y - y1 = m(x - x1)

substitute using the ordered pair, (-1, 3):

y - 3 = -2.5(x + 1)

Distribute:

y - 3 = -2.5x + -2.5

Add 3 to both sides:

y = -2.5 + 0.5

Double check by using the other ordered pair.

(1, -2)

y + 2 = -2.5(x - 1)

Distribute:

y + 2 = -2.5x - 2.5

Add 2 to both sides:

y = -2.5x + 0.5

(-1, 3) and (1, -2) written in slope intercept form is:

y = -2.5x + 0.5

[tex]g(x)=x^3-x\\g(-2)=(-2)^3-(-2)\\g(-2)=-8+2\\g(-2)=-6[/tex]

Therefore, g(-2) = -6

Basically substitute x = -2 in the equation.
