Answer:

A and B

Step-by-step explanation:

we have:

A: 2x-3y=6

-3y=-2x+6

3y=2x-6

y=2x-6/3

y=2/3x-2

so the slope here is 2/3

B: 3x-2y=-9

-2y=-3x-9

2y=3x+9

y=3/2x+9/2

so the slope here is 3/2

in C the slope is -32 and in D it's 23

perpendicular lines can be known using the rule:

slope (first line)=-1/slope (second line)

2/3= -1 over 3/2

so A and B are the two perpendicular lines

As x increases by 1 unit, what is the exponential growth factor??
san4es73 [151]

Given:

The graph of an exponential function.

To find:

The exponential growth factor as x increases by 1 unit.

Solution:

From the given graph, it is clear that the exponential function passes through the points (1,1) and (3,9). So, the equation of the exponential must must be satisfy by these points.

The general exponential function is:

y=ab^x                 ...(i)

Where, a is the initial value and b is the growth factor.

Putting x=1,y=1 in (i), we get

1=ab^1                  ...(ii)

Putting x=3,y=9 in (i), we get

9=ab^3                  ...(iii)

Divide (iii) by (ii).

\dfrac{9}{1}=\dfrac{ab^3}{ab}

9=b^2

3=b

b is the the growth factor and the value of b is 3.

Therefore, the exponential growth factor is 3 as x increases by 1 unit.

Please help 100 points
iren2701 [21]

Here's a trick.

Don't solve all the equations, you're given the answer to x so just substitute.

5/2*8+7/2=3/4*8+14

23.5=20 INCORRECT

5/4*8-9=3/2*8-21

1=-9 INCORRECT

5/4*8-2=3/2*8-4 <- YOUR ANSWER

8=8 CORRECT

Question: One third of a number, decreased by thirty-six is at most twenty-two.
IceJOKER [234]
First write it out.
1/3x - 36 ≥ 22
Add 36 to both sides
1/3x ≥ 58
divide both sides by 1/3, and you get 174
