7. Bobby wants to check if (4,2) is on the line y = 5x - 18. Lisa also wants to check if (3,-3) is on the
same
line. Show your work, and write a statement (sentence) about who's point is on the line. (8 pts)

Answers

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.

Solve 0.25x + 7 = 1/5 x -8

Answers

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

Change 95.61 to degrees, minutes, and seconds.

a.95° 43´ 44´´
c.95' 36´ 36´´
b.95° 41´ 43´´
d.95° 44´ 60´´

Answers

The answers are 95 36 36

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:

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

if a pair of standard dice are rolled what is the probability that the sum will be less that 5

Answers

Answer:

1/6

Step-by-step explanation:

Acellus sux

The probability of the pair of standard dice to be rolled and for their sum to be less than 5 is [tex]\frac{1}{6}[/tex]

What is probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

According to the given problem,

The possible rolls can be represented by ordered pairs,

Where the first entry is the outcome of one die and the second is the outcome of the other.

(1 and 1) , (1 and 2) ,…….,(1 and 6), (2 and 1), (2 and 2),.......,(2 and 6),.....,(6 and 1) ,(6 and 2),....,(6 and 6).

There are 36 possible outcomes when two dice are rolled.

Pairs having sum less than 5: (1 and 1) ,(1 and 2) , (1 and 3) , (2 and 1) , (2 and 2), (3 and 1).

The probability that the sum is less than 5 = [tex]\frac{6}{36}[/tex]

                                                                       = [tex]\frac{1}{6}[/tex]

Hence, we can conclude, there is a probability of  [tex]\frac{1}{6}[/tex] for the standard dice to be rolled and for their sum to be less than 5.

write in slope intercept form (-1,3) (1,-2)

Answers

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

3x = 35 - 8

3x = 27

x = 9

The smaller number = 9

The larger number = 2*9 + 8 = 26
