In the graph shown, suppose that f(x) = 3.5x and h(x) = 1.5x. Choose the statement that COULD be true.
faust18 [17]

Answer: D

Step-by-step explanation:

The given functions are

Now these are exponential curves and the bases for the functions are 3.5 & 1.5

Also the graph of g(x) is between f(x) & h(x)

Hence the value of base called the scale factor must be between 3.5 & 1.5.

4 & 5 are more than 3.5

0.9 is smaller than 1.5

But π = 3.14 lies between 3.5 & 1.5.

Hence the only option which can represent the graph of g(x) is

Option D) is the right answer

3x+1. I need to find and write an equation for x
Alchen [17]

Answer:

x =\frac{-1}{3}

Step-by-step explanation:

As the given algebraic expression is

3x+1

In order to solve the expression 3x+1 for x, we have to

3x+1=0

Step 1: Subtract 1 from both sides

3x+1-1=0-1

3x=-1

Step 2: Divide both sides by 3.

\frac{3x}{3} =\frac{-1}{3}

x =\frac{-1}{3}

Therefore, x =\frac{-1}{3}

What numbers multiply to -756 but when added = 1
telo118 [61]
So?
-756*x +x =1 ?
-755 x = 1
x= -1/755

or
what two numbers when multiplied equal -756 but when added together equal 1?

numbers are x and y
x*y= -756
x+y=1

rearrange the 2nd eq
y=1-x
substitute

x(1-x)=-756
distribute
x-x^2=-756
solve for zero
x^2-x-756=0
