Answer:

D

Step-by-step explanation:

Line A's slope: 9-1/2+2 = 8/4 = 2

y = 2x+b

y = 2x-5

If the slope of 2 lines are equal, then the lines are parallel.                    

Answer:

(3x^2+6x)/(x^2-16)

Step-by-step explanation:

When multiplying fractions you just go straight accross

this means that our fraction is equal to

((x+2)(3x))/((x-4)(x+4))

The numerator is quite easy 3x(x+2)=3x^2+6x

The second one is a little tough at first and if you need help I would reccomend using khan academy

but pretty much you get x^2-16

put them together and get your answer

Answer: 35. The equation would be y = 17/2x

Answer:

32) yes, linear

33) no

34) yes

Step-by-step explanation:

32) if you look at the difference in the y-values and the difference of the x-values you will see that they all equal 3; for example, 24/8, 21/7, 18/6

33) following same method as for #32, there is not a consistent ratio of change between x-and-y values

34) yes, constant ratio is 10

[tex]P > 300[/tex]

Step-by-step explanation:

Given

An art sold for over $300

Required

Represent as an inequality

Represent the price with p.

This implies that; P is over 300

In inequalities; the term "over" means greater than i.e. >

Hence:

P is over 300 is equivalent to [tex]P > 300[/tex]

Answer:

16π cm²

Step-by-step explanation:

circumference = 2πr

Area = πr²

We need to determine r to calculate the area

2πr = 8π

Divide both sides of the equation by 2π to find r

r = 4

Now, we determine area.

area =  πr² =   π4² = 16πcm²

Answer:

Step-by-step explanation:

The formula for the circumference of a circle can be used to solve this problem.

[tex]\underline{\text{CIRCLE OF A CIRCUMFERENCE FORMULA:}}[/tex]

[tex]:\Longrightarrow: \sf{C=2\pi r}[/tex]

[tex]\text{AREA:}= \sf{\pi r^2}[/tex]

[tex]\sf{2\pi r=8 \pi}[/tex]

You have to divide by 2 from both sides.

[tex]\sf{\dfrac{2\pi r }{2}=\dfrac{8\pi}{2} }[/tex]

Solve.

Divde the numbers from left to right.

8/2=4

r=4

[tex]\sf{\pi r^2=\pi4^2}[/tex]

Solve by exponents.

[tex]\sf{4^2=4*4=\boxed{\sf{16}}[/tex]

[tex]\Longrightarrow: \boxed{\sf{16\pi \text{cm}^2}}[/tex]

I hope this helps. Let me know if you have any questions.

Answer:

5^12

Step-by-step explanation:

When you have a power to the power, you multiply the powers. Since we have (5^3)^4, we can multiply the powers because we have a power to the power. Since 3 * 4 is equal to 12, we have 5^12. That means that 5^12 is the answer.

Answer:

Her percent error was: ≈ 17% (whole percent)

Step-by-step explanation:

Given

Approximate value = 20 friends

Exact Value = 24 friends

To determine

Percent error

Using the formula to calculate the Percent error

Percent error = | Approximate Value| - Exact Value | / | Exact value | × 100

                       = | 20 - 24 | / | 24 | × 100

                       = | - 4 | / | 24 | × 100

Apply absolute value: |-a| = a,   a>0

                       = 4/24 × 100

                       = 16.67 %

                       ≈ 17% (whole percent)

Thus, her percent error was: ≈ 17% (whole percent)

Answer:

Tom's share = €800

Step-by-step explanation:

Given that:

Amount shared by Al, Tom and Joe = €3000

Ratio of Al's share to Tom's share = 5 : 4

Joe's share = 1.5(Tom's share) = 1.5(4) = 6

Therefore,

Ratio of Al, Tom and Joe = 5 : 4 : 6

Let,

x be the number of times of amount each get.

5x + 4x + 6x = 3000

15x = 3000

Dividing both sides by 15

[tex]\frac{15x}{15}=\frac{3000}{15}\\x=200[/tex]

Tom's share = 4x = 4(200) = €800

Hence,

Tom's share = €800

Answer:

JML=142 degrees

Step-by-step explanation:

This shape is a rhombus, as all 4 sides are equal, but the angle measures are not. One of the properties of a rhombus is that opposite angles are congruent, and adjacent angles are supplementary. Only the second one is important. Since angles KLM and angle JML are supplementary, the equation KLM+JML=180 can be used. KLM is then substituted by the given angle measure, 38 degrees, to get an equation such as JML+38=180. Now, to solve for JML, 38 must be subtracted from both sides of the equation, which leaves teh answer of JML=142.

Answer:

x = 145

Step-by-step explanation:

x and 35 are adjacent angles and are supplementary, sum to 180° , then

x + 35 = 180 ( subtract 35 from both sides )

x = 145

Answer:

(0,0) (1,6) (2,12)

Step-by-step explanation:

Proportional relationships are also known as direct variation, so I'll refer to it as DV.

The formula for finding DV is y=kx.

In this case, k=6, which is just y=6x. So, essentially..

(0,0) (1,6) (2,12) etc.

The points that lies on the graph of the line representing the relationship are (0, 0), (1, 60, and (2, 12).

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

As, we know that the constant proportionality have

y= k x

where k is constant of proportionality.

We have given that constant of proportionality = 6

So, y= 6x

Now, when x=0

y=0

and, x=1

y= 6

and, x=2

y= 12

Hence, the points are (0, 0), (1, 60, and (2, 12).

Answer:

x = 0, x = 1, x = - 3

Step-by-step explanation:

To find the zeros, let f(x) = 0 , that is

(x - 1)(x(x + 1) + 2x) = 0  ← distribute and simplify parenthesis

(x - 1)(x² + x + 2x) = 0

(x - 1)(x² + 3x) = 0 ← factor out x from the second parenthesis

x(x - 1)(x + 3) = 0

Equate each factor to zero and solve for x

x = 0

x - 1 = 0 ⇒ x = 1

x + 3 = 0 ⇒ x = - 3

Answer:

13.9%

Step-by-step explanation:

First, we find the amount of decrease.

$3.60 - $3.10 = $0.50

The price decreased $0.50.

Now we find what percent $0.50 is of $3.60.

percent = part/whole * 100%

percent = $0.50/$3.60 * 100%

percent = 0.13888 * 100% = 13.9%

Answer: 13.9%
