Answer:

Step-by-step explanation: you forgot to attach the file but it should look like this i think

Answer:

slope is 3/4

y-intercept is (0,-3)  Thats where you put your first point on the y-inter on -3

x    y

0   -3

4     0

Put your second point at 4 (on the x)

then your slope is rise /run 3/4

then you should get your line on your graph

Answer:

20% tip = $4.40; total = $26.4

Step-by-step explanation:

20 % = 0.20 ------> 22 * 0.20 = 20% of 22

20% of $22.00 = $4.40

total = $22.00 + $4.40

total = $26.40

Answer:

circumfrence = 108

Step-by-step explanation:

Radius = half the circumfrence

radius * 2 = circum.

54*2 = 108

108 = circum

Answer:

1 and 19

Step-by-step explanation:

I believe this is a factoring problem.

Example:

If we have the equation x^2-2x-3

We can find two numbers that multiply to -3 that add to -2

The two numbers are -3 and 1

(x-3)(x+1)= So x=3 and x=1

Answer:

1 and 19

Explanation:

1x19=19

1+19=20

Hello!

[tex]\large\boxed{\text{n = 5, m = 9, x = 512}}[/tex]

An exponential expression in form [tex]\sqrt[z]{x^{y} }[/tex] can be rewritten as [tex]x^{\frac{y}{z} }[/tex] where "z" is the root and "y" is the power. For example:

[tex]x^{\frac{2}{3} } = \sqrt[3]{x^{2} }[/tex].

We can apply this idea to this problem:

[tex](32)^{\frac{9}{5} } = (\sqrt[5]{32^{9} } )[/tex]

Therefore:

n = 5

m = 9

Simplify the expression:

[tex]\sqrt[5]{32^{9} } = (\sqrt[5]{32} )^{9}[/tex]

[tex]\sqrt[5]{32} = 2\\\\2^{9} = 512[/tex]

Therefore, the values of all letters are:

n = 5

m = 9

x = 512

Answer:

n=5

m=9

x=512

Answer:

28 soccer balls.

Step-by-step explanation:

Let there are 7x basketball and 6x soccer balls.

A sports store donates basketballs and soccer balls to the boys and girls club.

The store donates 24 soccer balls.

It means,

6x = 24

x = 4

No of basketballs = 7x

= 7(4)

= 28

Hence, the store denote 28 soccer balls.

Answer:

75 feet

Step-by-step explanation:

Answer:

27

Step-by-step explanation:

Proportion

6 feet man/10 feet shadow = x (tree) / 45 feet (shadow)

6/10 = x /45            Cross multiply

10x = 45*6

10x = 270

x = 270/10

x = 27

The tree is 27 feet long

Answer:

a = 2

Step-by-step explanation:

Hope this helps and have a nice day :)

Answer:

a=3

Step-by-step explanation:

24=3(2a-14)-3a

distribute

24=6a-42-3a

subtract 3a from 6a

24=3a-42

add 42 to both sides

66=3a

divide 3

3=a

a=3

hope this helps :)

Answer:

The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

Equality Properties

Algebra I

Step-by-step explanation:

Step 1: Define Equation

2(x + 2x) = 36

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 36 does indeed equal 36.

∴ x = 6 is the solution to the equation.

Answer :

2(x+2x)=36

2x + 4x =36

6x =36 is the answer

Answer:

N and P are equal to 48 degrees

Step-by-step explanation:

1. 3y^2=12y^2−144

2. Subtract 3y^2 from both sides

3. add 144 to both sides

4. 9y^2= 144

5. Divide both sides by 9

6. y^2 = 16

7. Take the square root of 16 ( which is y=±√16)

8.  y = 4 or y = -4

(in this case, Y would equal 4 since the angles are not negative lol)

9. Plug 4 into the equations

10. Compare each answer to see if they are equal

Answer:

∠ N = ∠ P = 48°

Step-by-step explanation:

Δ KMP and Δ LJN are similar ( AA postulate ), then corresponding angles are congruent,  that is

∠ P = ∠ N

12y² - 144 = 3y² ( subtract 3y² from both sides )

9y² - 144 = 0 ( add 144 to both sides )

9y² = 144 ( divide both sides by 9 )

y² = 16 ( take the square root of both sides )

y = [tex]\sqrt{16}[/tex] = 4

Then

∠ N = 3y² = 3(4)² = 3(16) = 48² = ∠ P

Answer:

y = -1/5x + 2

Step-by-step explanation:

I will assume the "-" is an equal sign. Solve for y.

x + 5y = 10

~Subtract x to both sides

5y = 10 - x

~Divide 5 to everything

y = 2 - 1/5x

~Reorder

y = -1/5x + 2

Answer:

DrPepper is a carbonated soft drink. It was created in the 1880s by pharmacist Charles Alderton in Waco, Texas, and first served around 1885. Dr Pepper was first nationally marketed in the United States in 1904 and is now also sold in Europe, Asia, North and South America, and Australia, as well as New Zealand and South Africa as an imported good. Variants include Diet Dr Pepper and, beginning in the 2000s, a line of additional flavors.
