What is an
equation of the line that passes through the points (-8,-4) and
(-8, – 7)?

Answer:

-12, -14, -16

Step-by-step explanation:

x + (x+2) + (x+4) = -42

3x + 6 = -42

Isolate the variable 3x by subtracting 6 from both sides

3x = -48

Then isolate the variable x by dividing 3 from both sides

x = -16

Then add 2 for the 2nd number

Then add 4 for the third number

Answer:

.9

Step-by-step explanation:

sinx=opp/hyp 18/20=.9

The factor of the polynomial is be (x+12)

We have given equation is

[tex]x^2+8x-48[/tex]

The middle number is 8 and the last number is -48.

Factoring means we want something like

[tex](x-a)and (x+b)[/tex]

we have to find the value of a and b

The numbers are (12) and -4

addition=12+(-4)=12-4=8

12(-4)=-48

Therefore we have,

[tex]x^2+8x-48\\x^2+12x-4x-48\\\\x(x+12)-4(x+12)\\(x-4)(x+12)[/tex]

Therefore the given equation has two factor that are (x-4) and (x+12)

Since (x-4) is not in option therefore  the answer would be (x+12)

Answer:

$418

$498

Step-by-step explanation:

Jordan has - 3 * $100 = $300,

                     4 * $20 = $80,

                     1 * $ 10 = $10,

                     8 * $1 = $8

Total =              $398

Jordan’s total will be $418 if Jayla gives him one more $20 bill?

Jordan’s total will be $498 if Jayla gives him one more $100 bill?

Jordan's total will be $438 if Jayla gives him one more $20 bill.

Jordan's total will be $498 if Jayla gives him one more $100 bill.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If Jayla gives Jordan one more $20 bill, then Jordan will have:

3 x $100 = $300

5 x $20 = $100

1 x $10 = $10

8 x $1 = $8

1 x $20 = $20

Adding these up gives:

$300 + $100 + $10 + $8 + $20 = $438

Jordan's total will be $438 if Jayla gives him one more $20 bill.

If Jayla gives Jordan one more $100 bill instead, then Jordan will have:

4 x $100 = $400

4 x $20 = $80

1 x $10 = $10

8 x $1 = $8

Adding these up gives

$400 + $80 + $10 + $8 = $498

Therefore,

Jordan's total will be $438 if Jayla gives him one more $20 bill.

Jordan's total will be $498 if Jayla gives him one more $100 bill.

Answer:6.6 x 101

Step-by-step explanation:

The selling price of the DVD that has a cost of 15 dollars is 19 dollars and 50 cents.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

A store owner paid $15 for a DVD.

He marked up the price of the DVD by 30%.

The cost price is $15.

Then the selling price will be given as

Selling price = 15 × 1.3

Selling price = $19.50

The selling price is 19 dollars and 50 cents.

Answer:

400

Step-by-step explanation:

Let the number be known as "x".

Given statement:

45% of a number is 180.

The term "of" defines multiplication between two terms. In this case, the terms are 45% and the number "x". Therefore,

     ⇒ 45% × x = 180

When we convert a percentage into a fraction, simply divide the percentage by 100 and remove the percentage sign to obtain the result in fraction form.

     ⇒ 45/100 × x = 180

Multiplying 45/100 and x:

     ⇒ 45/100 × x = 180

     ⇒ 45x/100 = 180

Using cross multiplication:

     ⇒ 45x/100 = 180

     ⇒ 45x = 180 × 100

Simplifying the right-hand-side:

     ⇒ 45x = 180 × 100

     ⇒ 45x = 18000

Dividing 45 to both sides of the equation:

     ⇒ 45x = 18000

     ⇒ 45x/45 = 18000/45

     ⇒ x = 18000/45 = 400

Therefore, the number is 400.

Answer:

kpm is about 110.02 degrees

Step-by-step explanation:

-kpl and npm are vertical angles, so they're congruent

-npm and lpm are supplementary angles, meaning they add to 180 degrees

we r given:

npm = 14x - 22

lpm = 7x + 4

add these and set equal to 180:

14x - 22 + 7x + 4 = 180

then combine like terms:

21x -18 = 180

isolate the variable by adding 18 on both sides:

21x = 198

divide by 21 on both sides:

x = about 9.43

since kpl and npm r congruent, plug in the value of x in npm (14x-22):

14(9.43)-22

= 110.02

Answer:

y=-2/7x-61/7

Step-by-step explanation:

convert to slope intercept form

2x+7y=9

7y=-2x+9

y=-2/7x+9/7

slope is -2/7

-7-2/7=-51/7

y=-2/7x-61/7

Answer:

[tex]y=-\frac{2}{7}x-\frac{51}{7}[/tex]

Step-by-step explanation:

Hi there!

We are given the line 2x+7y=9

We want to find the equation of the line that contains the point (-1, -7), and that is parallel to the equation above

Parallel lines have the same slopes.

So we need to find the slope of 2x+7y=9

One way to do this is to convert 2x+7y=9, which is currently in standard form (ax+by=c) into slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept.

In slope-intercept form, y is isolated by itself, so let's start by moving 2x to the other side (it removes it from the left side)

2x+7y=9
-2x      -2x

____________
7y=-2x+9

Now divide both sides by 7

[tex]y=-\frac{2}{7} x + \frac{9}{7}[/tex]

in this equation, -2/7 is in the place of where m should be. This means that -2/7 is the slope of this line.

It is also the slope of the line parallel to it.

The instructions want us to write this equation in slope-intercept form, so let's plug -2/7 as m into the formula.

Here is the equation of the line so far:

[tex]y=-\frac{2}{7}x + b[/tex]

Now we need to find b.

As the equation contains the point (-1, -7), we can use it to help solve for b.

Substitute -1 as x and -7 as y into the equation

[tex]-7=-\frac{2}{7}(-1) + b[/tex]

Multiply

[tex]-7=\frac{2}{7} + b[/tex]

Subtract 2/7 from both sides

[tex]-\frac{51}{7} = b[/tex]

Substitute -51/7 as b in the equation

[tex]y=-\frac{2}{7}x-\frac{51}{7}[/tex]

Answer is Step-by-step explanation:

The two shorter sides are the legs of the right triangles. Both are given for triangle B. Use Pythagorean Theorem or pythagorean triples(shortcut/special case) to show the missing side of Triangle A is also 5.

leg^2+ leg^2 = hyp^2

x^2 + 12^2 = 13^2

x^2 + 144 = 169

subtract 144.

x^2 = 25

square root both sides.

x = 5

The missing side of Triangle A is 5, same as triangle B.

Just to really show it. Calc the missing side of triangle B

5^2 + 12^2 = h^2

25 + 144 = h^2

169 = h^2

squareroot both sides.

13 = h

The hypotenuse of both triangles is 13. All the measures of all the corresponding sides are the same for these two triangles.

Answer:

First we need to find a common denominator;

3 1/4 and -5/8 have a common denominator of 8

-5/8 already has 8 now we alter 3 1/4 to have 8 as the denominator as well.

if we make 3 1/4 into an improper fraction we would get 13/4

13/4 x 2/2 = 26/8, because 2 x 4 = 8 so we also apply that to the numerator

Now we have;

26/8 - (-5/8)

the two negatives combine to make a positive:

26/8 + 5/8

= 31/8 which simplifies to

3 7/8
