Answer:

1B , 2B , 3 Output = 2*input + 1

Step-by-step explanation:

1. given (3n + 5) * 2

first do the operation between brackets.

n=5 so (3*5) =15 which gives (15 + 5)=20

now finish with the operation after the brackets, which is multiply by 2. 20*2 = 40, which is answer B.

2. 3x means 3*x which means in words: 3 times the number, which is answer A.

3. From the tabe you can see that if you just multiply the input by 2, you are almost at the output. If you add 1 then it is perfect..So you get Output = 2*input + 1

Answer:

<u>Third Option</u>: y = \frac{5}{4}x

Step-by-step explanation:

Given the points on the graph, (4, 5) and (-4, -5):

In order to determine the equation of the given graph in slope-intercept form, y = mx + b:

Use the given points to solve for the slope:

Let (x₁, y₁) = (-4, -5)

(x₂, y₂) = (4, 5)

m = (y₂ - y₁)/(x₂ - x₁)

m = \frac{5 - (5)}{4 - (-4)}  = \frac{5 + 5}{4 + 4}  = \frac{10}{8} = \frac{5}{4}

Therefore, the slope of the line is: m = \frac{5}{4}.

Next, use one of the given points on the graph, (4, 5) to solve for the y-intercept, b:

y = mx + b

5 = \frac{5}{4} (4) + b

5 = 5 + b

5 - 5 = 5 - 5 + b

0 = b

Therefore, the linear equation in slope-intercept form is: y = \frac{5}{4}x.  The correct answer is Option 3.
