Answer:

the 4th graph.

Step-by-step explanation:

by solving for Y in the first equation, we get the y-intercept of -1 and the second equation has a y-intercept of 1. 4th graph is the only graph with those 2 intercepts

Answer:

[tex]y = -\frac{3}{4}x-\frac{3}{2}[/tex]

Step-by-step explanation:

First, calculate the slope of the line:

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{(-6) - 3}{6 - (-6)}\\m = \frac{-9}{12}\\m = \frac{-3}{4}[/tex]

Next, calculate the y-intercept:

Choose any point on the line.

[tex](-6,3)[/tex]

Solve for [tex]b[/tex].

[tex]y = mx + b\\b = y - (mx)\\b = 3 - (\frac{-3}{4} * -6)\\b = 3 - \frac{9}{2}\\b = \frac{-3}{2}[/tex]

Finally, create the equation:

 [tex]y = -\frac{3}{4}x-\frac{3}{2}[/tex]

Answer:

----------------------------------------------------------------------------------------------------------

Any negative number added to a positive number always brings you further to the left, which is considered the negative zone. It's more like subtracting in a different way. That said, let's make the equation.

[tex]-4 = -4[/tex]

Now, multiply 3 by 8.

[tex]3 * 8 = 24[/tex]

Add negative 4, meaning subtract 4 in a dynamic way.

[tex]|-4 + 24~| = 20[/tex]

Answer:

-33, -40

Step-by-step explanation:

If you figure out the patern here, the patern is (-7).

So I did (-26-7) which got me -33, and then did, (-33-7) which got me -40.

Hopefully this helps :)

= 5 : 6 ← in simplest form

Answer:

The answer would be C. 8 hundredths.

Answer:

A(t) = amount remaining in t years

      = A0ekt, where A0 is the initial amount and k is a constant to                     be determined.  

Since A(1690) = (1/2)A0 and A0 = 80,

                we have 40 = 80e1690k

                1/2 = e1690k

                ln(1/2) = 1690k

                k = -0.0004

So, A(t) = 80e-0.0004t

Therefore, A(430) = 80e-0.0004(430)

                           = 80e-0.172

                           ≈ 67.4 g

Step-by-step explanation:

Answer:

The one on the right is a proportional relationship between x and y

Step-by-step explanation:

Your going to have the divide y by x so (y ÷ x)

5÷2 = 2.5

10÷4 = 2.5

15÷6 = 2.5

They all end up having the same answer. So when you divide y by x, you have to have the same answer for every single one.

Answer:

Cost of slate path using π:   $980.18 (nearest cent)

Cost of slate path using π = 3.14:   $979.68

Step-by-step explanation:

Formula

Area of a circle = πr²  (where r is the radius)

First, calculate the area of the slate path by subtracting the area of the pond from the area of the larger circle.

Area of larger circle = π · 8² = 64π ft²

Area of pond (smaller circle) = π · 4² = 16π ft²

⇒ area of slate path = 64π - 16π = 48π ft²

If the cost of the slate is $6.50 per ft² then,

Cost of slate path using π:

⇒ 48π × $6.50 = $980.18 (nearest cent)

Cost of slate path using π = 3.14:

⇒ 48 × 3.14 × $6.50 = $979.68

Answer: what I understood from the question that you want this side and the other side so the fust side equals 33 and the second side after the equal side equals -20 so 33 = -20

The coordinate of a function are written in the form (x, y). The coordinates (11, 108) and (15, 140) satisfy the function

The coordinate of a function are written in the form (x, y)

Given the amount of money Emily spends, after r rides, at a carnival

is modeled by the function y = 8r + 20

We are to determine the coordinate that satisfies the function

For the coordinate (15, 140)

If r = 15, then

y = 15(8) + 20
y = 140

Hence the coordinate (15, 140) satisfy the function

For the coordinate (11, 108)

If r = 11, then

y = 11(8) + 20
y = 108

Hence the coordinate (11, 108) satisfy the function

Answer:

3/8

Step-by-step explanation:

We have to use a common denominator of 8 for this problem. 3/4 = 6/8. 6/8  - 3/8 is 3/8. 3/8 is in its simplest form, so that would be the answer.

Answer:

3/8

Step-by-step explanation:

Reduce the fraction to lowest terms

1 is the greatest common divisor of 3 and 8. The result can't be further reduced.

20 -4 { 20÷ 7 ( 7 - 3 )}

20 -4 { 20 ÷ 7 * 4 }

20 - 4 { 2.85 * 4 }

Answer:

55°

Step-by-step explanation:

[tex]m\angle C = \frac{1}{2} (184 \degree - 74 \degree) \\ \\ \implies \: m\angle C = \frac{1}{2} (110 \degree) \\ \\ \implies \: m\angle C = 55 \degree[/tex]
