Answer:

1.11

Step-by-step explanation:

The Slope is defined as the rate of change.

In this case,

Slope = -200+100/-180+90

         = -100/-90

         = 10/9

         = 1.11

Answer:

the equation x - 18 = 4(x - 18)

Answer: The evaluated answer is 8. The coefficient is 6. The variable is y. The constant is 5.

Step-by-step explanation for the evaluated answer: Just substitute 1/2 for y. You should get 6x1/2+5. Then, multiply the 6 and the 1/2 and you should get 6/2+5. 6/2 can be simplified to 3 and then you just need to add the five to get 3+5=8. S your final answer should be 8. Hope this helps!

I'm pretty sure is number two

Step-by-step explanation:

because I solved the problems

Answer:

The answer is A

Step-by-step explanation:

Express the number in scientific notation as real numbers:

[tex]9.4 \times {10}^{ - 8} = 0.000000094 \\ 9.25 \times {10}^{ - 6} = 0.00000925 \\ 2.5 \times {10}^{3} = 2500 \\ 7 \times {10}^{3} = 7000[/tex]

So, from least to greatest;

[tex]0.000000094 - 0.00000925 - 2500 - 7000[/tex]

Answer:

x = 8

Step-by-step explanation:

3(x-2)=18

3x-6=18

3x=24

x=24/3

x=8

Answer:

x = 8

Step-by-step explanation:

3 (x - 2) = 18

3x - 6 = 18

18 + 6 = 24

3x = 24

The value of the stock when Mateo’s aunt bought it was $150.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We need to find the value of the stock when Mateo’s aunt bought it.

Given that the value of the stock increased by 80%. Its value is now $270.

The stock has increased 80% thus it is now worth 180%.

Then Divide by 180;

$270/180 = $1.50

Now find 100% then Multiply by 100;

$1.50 X 100 = $150

The value of the stock when Mateo’s aunt bought it was $150.

Answer:

1/5

1/3

Step-by-step explanation:

For the first problem:

5/7 of ... is 1/7

so

5/7 of x is equal to 1/7

so

(5/7)x = (1/7)

so

x = (1/7)/(5/7)

so

x = 1/5

For the second problem:

5/7 of ... is 5/21

so

5/7 of x is equal to 5/21

so

(5/7)x = (5/21)

so

x = (5/21)/(5/7)

so

x = 1/3

Answer:

c

Step-by-step explanation:

because a proportional relationship can be thought of as one is always the same then gets times by the other or in this case 4 by x

Options A and C have a proportional relationship.

Given that, the total amount of toys a child earns when he earns 2 toys a week for w weeks.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

A) Let the total number of toys be x

So, x=2w

B) Let the total amount a taxi driver earns be y

So, y=3+m

C) Total cost of buying x avocados be p

So, p=4x

D) Let the total amount a Gardner earns be c

So, c=10+15r

Therefore, options A and C have a proportional relationship.

#SPJ2

Answer:

The answer is D. k=5

Step-by-step explanation:

The constant of proportionality is just the rate the x increases or decreases at.  The x is increasing by 5 over time so the COP or rate is 5.

Answer:

The answer is D: K=5

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

So, what you do is that you get the first number, which is 5/25. Simplify it and divided to get it as low as possible, if you do that, you would get 1/5 and 1/5 can also mean 5/1 in these situations. So your basic answer is 5.

Answer:

-14

Step-by-step explanation:

Answer:

-14, fourth choice

Step-by-step explanation:

absolute value is represented with this |x|, the 2 lines

The absolute value for a real number, in this case -14, is the non-negative value without regard to its sign. So the absolute value of -5 would be 5, and the absolute value of 7 would still be 7

In this case there's no 14, so u can choose -14

Answer:

B

Step-by-step explanation:

Answer:

Step-by-step explanation:

Combine like terms:

-4x - 9x = (-4 - 9)x = -13x

4x - (-9x) = 4x + 9x = (4 + 9)x = 13x

-4x + 9x = (-4 + 9)x = 5x

4x - 9x = (4 - 9)x = -5x
