Three lines are given on each graph that intersect at one point. Find the slope-intercept equation of each line. Graph and write an equation for one additional line that intersects at the same point. Vertical and horizontal lines are not permitted.

Hello!

[tex]\large\boxed{Slope = -\frac{1}{2}}[/tex]

Use the slope formula along with provided points to solve for the slope.

We can use the points (-4, -1) and (0, -3) and plug these values into the equation:

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]m = \frac{-3-(-1)}{0-(-4)} \\\\m = \frac{-2}{4} \\\\m = -\frac{1}{2}[/tex]

Answer:

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

Step-by-step explanation:

x - 18 = 4x - 72

x - 4x = - 72 + 18

- 3x = - 54

x = 54/3

x = 18

Sally had 36 postcards to begin with (18 + 18)

martha had 0 postcards to begin with

i feel like i did something wrong someone double check this but i think this is the answer.

Answer:

x-18 = 4(x-18)

Step-by-step explanation:

x-18 =4x-72

3x =54

x=54/3

x=27

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

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: 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!

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:

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;

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.
