When n = 3, which of the expressions below will be greater than 50? Select all that apply. A) (8n2÷9)⋅7 B) 2n2⋅3 –4n C) 4n2–6n+1

True [87]

Answer:

A

Step-by-step explanation:

a)

$(8(3)^{2} / 9) * 7$

8(9) / 9 = 8 x 7 = 56

$2(3)^{2} * 3 - 4(3)$

2(9) * 3 - 12

18 * 3 = 54 - 12 = 42

$4(3)^{2} - 6(3) + 12$

4(9) - 18 + 12

36 - 18 = 18 + 12 = 30

$7(3) + (3 * 8)$

21 + 24 = 45

WILL MARK BRAINLIEST in detail, what would you do in order to graph y = 3x -5

Hunter-Best [27]

So first, you need to identify the parts of this equation.

3x is the slope of the line, which is $\frac{3}{1}$ .

-5 is the y-intercept. or the part of the line that touches the y-axis.

The first thing you want to do is plot the y-intercept. SO, go to the y-axis and find -5. Plot your point there.

Now, use the slope $\frac{3}{1}$ to find your next plot. Since slope is $\frac{rise}{run}$ , you go up three, and over to the right one.

Now, draw a line connecting the dots. Your slope should be positive and look like > /
