Which of the following is a proportion?

Answer:

1)y=2x+7

2) unsure what the question is due to blur

3)y=3/4x-2

4)y=-2x

Answer:

Step-by-step explanation:

1) (1,9) ; slope = 2

Point slope form:

y - y₁ = m(x - x₁)

y - 9 = 2(x - 1)

Slope intercept form:

y - 9 = 2x - 2

    y = 2x - 2 + 9

 y = 2x + 7

3) (-4 , -5)  ; slope = 3/5

Point slope form:

y - y₁ = m(x - x₁)

[tex]y - [-5] = \dfrac{3}{4}(x - [-4])\\\\\\y + 5 = \dfrac{3}{4}(x + 4)[/tex]

Slope intercept form:

[tex]y + 5 = \dfrac{3}{4}x + 4*\dfrac{3}{4}\\\\y + 5 =\dfrac{3}{4}x + 3\\\\y = \dfrac{3}{4}x +3 -5 \\\\\\y = \dfrac{3}{4}x - 2[/tex]

Answer:

1014

Step-by-step explanation:

Remember this formula to find certain terms in arithmetic sequences:

[tex]t_{n} =t_{1} +(n-1)d[/tex]

n = term number

[tex]t_{1}[/tex] = term #1

d = common difference

Sequence = 24, 34, 44, 54...

We are looking for term #100

So we do

[tex]t_{100} = 24 + (100-1)10\\t_{100} = 24 + 1000 - 10\\t_{100} = 24 + 990\\t_{100} = 1014[/tex]

Answer:

0.41, 2 is lower than 5 so we round down

Answer:

0.41300

Step-by-step explanation:

0.41275.

0.4: tenths place. 0.01: hundredths place. ...

Now look at the next decimal place, which is 0.0007: the ten thousandths place . This number determines whether the thousandths place will be rounded up or down. ...

Therefore, 0.41275 rounded to the nearest thousandth is:

Answer: Percentage decrease = 20% × 7,720

New value = 7,720 - Percentage decreaseNew value =

7,720 - Percentage decrease =

7,720 - (20% × 7,720) =

7,720 - 20% × 7,720 =

(1 - 20%) × 7,720 =

(100% - 20%) × 7,720 =

80% × 7,720 =

80 ÷ 100 × 7,720 =

80 × 7,720 ÷ 100 =

617,600 ÷ 100 =

6,176

New value - 7,720 =

6,176 - 7,720 =

- 1,544

Number of dogs:

Answer:

A

Step-by-step explanation:

The Explication 0 (7+4i)+(7-4i) = 14

The correct equation which demonstrates the additive identity property is,

⇒ (7 + 4i) + 0 = 7 + 4i

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Now, If we add a real number to zero or add zero to a real number, then we get the same real number back.

Hence, The number zero is known as the identity element, or the additive identity.

For example: a + 0 = a

Hence, we can see that;

⇒ (7 + 4i) + 0 = 7 + 4i

Since, 0 is the additive identity here.

Thus, The correct equation which demonstrates the additive identity property is,

⇒ (7 + 4i) + 0 = 7 + 4i

Answer:

m∠O = 80°

Step-by-step explanation:

m∠O = 4x - 20

m∠Q = 3x + 5

m∠O and m∠Q are congruent

4x - 20 = 3x + 5

Solve for x = 25

Plug back in

m∠O = 4(25) - 20

m∠O = 100 - 20

m∠O = 80°

Answer:

133

Step-by-step explanation:

665/5 = 133

3(6x+2) <9

Use distributive property:

18x + 6 < 9

Subtract 6 from both sides

18x < 3

Divide both sides by 18

Answer:

z = 36

Step-by-step explanation:

1) Distribute

-18 = -3z + 18 + 2z

2) Combine like terms

-18 = -z + 18

3) Subtract 18 from both sides of the equation

-18 - 18 = -z + 18 - 18

4) Simplify

a. Subtract the numbers

-36 = -z + 18 - 18

b. Subtract the numbers

-36 = z

5) Divide both sides of the equation by the same term

-36/ - 1 = -z/-1

6) Simplify

a. Divide the numbers

36 = -z/-1

b. Cancel terms that are in both the numerator and denominator

36 = z

c. Move the variable to the left

z = 36

Answer:

1.5

Step-by-step explanation:

to find one hour you divide both answers by 1.5 giving you one hour and 1.5

1.5 yards did you mow in 1 hour when, You mowed 2.25 yards in 1.5 hours.

Division is the process of splitting a number or an amount into equal parts.

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

You mowed 2.25 yards in 1.5 hours.

in 1 hours I mowed = 2.25/1.5

                               =1.5

Hence, 1.5 yards did you mow in 1 hour.
