Which Of The Following Is Equivalent To The Expression 2 ( 8y + 1/2 ) Select All That Apply.

Answers

Answer 1

Answer:

B and C both are equivalent to the expression

Answer 2

Answer:

B, C

Step-by-step explanation:

2(8y+1/2) would be equal to 2x8y+2x1/2=16y+1.

2(8y+1/2) would also be equal to 8y+1/2+8y+1/2 because multiplying by 2 is basically just adding the thing you are multiplying to itself.

5. Using the equation y=2x+5, construct a table and graph the line

Answers

Step-by-step explanation:

What you are going to do is for each value of x (which is the value to the right on the table) you will find the Y value.

So for X = 0

y = 2(0)+5 = 5

x = 1

y = 2(1)+5 = 7

x = 3

y = 2(3)+5 = 11

x = 5

y = 2(5)+5 = 15

x = 10

y = 2(10)+5 = 25

Now for what you do is place the correspanding value into the graph.

(x,y) = (0,5), (1,7), (3,11),(5,15),(10,25)

Answer:

The X is equal to 1.75

Step-by-step explanation:

3.5X2.25=7.875

14/7.875=1.75

Answer: x=1.75

Step-by-step explanation:

rearrange the term: 3.5 (2.25 + x) = 14

the new term: 3.5 (x + 2.25) = 14

Combine multiplied terms into a single fraction, then distribute.  

x = 1.75

Identify one point and the slope from the equation y + 4 = 1/3(x - 1)
Options:
m = 4 Point = (1/3, 1)

m = 1/3 Point = (1, -4)

m = 1/3 Point = (1, 4)

m = 1/3 Point = (-1, 4)

Answers

Answer:

m = 1/3 Point = (1, -4)

The slope is 1/3.

The point is 1,-4.

If you are wondering how I got the point, I just unsimplified the equation!

From y+4=1/3(x-1).

To y- -4=1/3(x-1).


The original formula is y-y1=m(x-x1). So we know where the y and the x is, and the slope.
