Answer:

y+10 = -5(x-3)

Explaination:

Finding the slope intercept form provides you with the line your looking for

here you want to isolate y

y = -5(x-3)-10

and then ditrubute the -5 into the parenthesis

y = -5+15-10

Combine like terms

y = -5x +5

and by looking at this in terms on y=mx+b

the line will intercept the y-axis at (5,0) like the line above shows

Answer:

The point that represents the bottom of the pool is [tex](x,y) = (-4, -16)[/tex].

Step-by-step explanation:

Given that the shape of the underground pool is a parabola, that is, a second order polynomial. Then, the point that represents the bottom of the pool is the vertex, which is contained in the standard form of the parabola. That is:

[tex]y-k = C\cdot (x-h)^{2}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]h[/tex], [tex]k[/tex] - Coordinates of the vertex, dimensionless.

[tex]C[/tex] - Constant, dimensionless.

The parabola is represented by [tex]f(x) = x^{2}+8\cdot x[/tex] and we proceed to transform into the desired form:

1) [tex]f(x) = x^{2}+8\cdot x[/tex] Given.

2) [tex]f(x) = (x^{2}+8\cdot x + 16)-16[/tex] Modulative property/Existence of the additive inverse.

3) [tex]f(x) +16 = (x+4)^{2}[/tex] Compatibility with the addition/Modulative property/Existence of the additive inverse/Perfect square trinomial.

4) [tex]y + 16 = (x+4)^{2}[/tex] Notation/Result.

Hence, the point that represents the bottom of the pool is [tex](x,y) = (-4, -16)[/tex].

Answer:

y = 75x +1

is the correct answer hope it is helpful to you ☺️

The linear equation for this situation is,

⇒ y = 75x

And, There are 75 apple pick in one hour.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The graph shows how many apples Erin can pick if she ,maintain a constant rate.

Now,

Let two points on the graph are (0, 0) and (1, 75).

So, Slope of the graph (m) = (75 - 0) / (1 - 0)

                                         = 75

Thus, The linear equation is;

⇒ y - y₁ = m (x - x₁)

⇒ y - 0 = 75 (x - 0)

⇒ y = 75x

Where, y is number of apples and x is number of hour.

Thus, Number of apple pick in one hour is;

⇒ y = 75 x 1

⇒ y = 75

So, There are 75 apple pick in one hour.

Therefore, The linear equation for this situation is,

⇒ y = 75x

And, There are 75 apple pick in one hour.

Answer:

question 1. (20)X = 100

question 2. the last one

Step-by-step explanation:

Answer:

Step-by-step explanation:

1.  20 a yard and made 100. 100/20=5 yards

20x=100

2. Since they don't give the number of yards they did mow, this would be my answer. I would say half the amount. Since they cut their rates in half, they'll have to cut twice as many to even the amount as before. They would have to cut three - four times as many to make over the original amount. They only have one weekend, so that'll be hard.

Answer:

C

Step-by-step explanation:

To simplify the equation, all you need to do is add 12 to both sides to cancel out the -12.

The equations that are equivalent to the equation 3x - 12 = 24 are

3x = 36

x - 4 = 8

15x - 60 = 120

Options A, C, and D are correct.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: x + 2 = 7 is an equation.

We have,

3x - 12 = 24 ____(1)

From (1)

Adding 12 on both sides.

3x = 24 + 12

3x = 36 ____(2)

From (1)

Dividing 3 into both sides.

x - 4 = 8 ____(3)

From (1)

Multiplying 5 into both sides.

5 (3x - 12) = 5 x 24

15x - 60 = 120 ____(4)

From (2), (3), and (4) we see that,

3x = 36

x - 4 = 8

15x - 60 = 120

Thus,

The equations that are equivalent to the equation 3x - 12 = 24 are

3x = 36

x - 4 = 8

15x - 60 = 120

Options A, C, and D are correct.
