Answer:

X - 7 = - 3

X = - 3 + 7

X = 4

the 7 turns positive because it was moved to the other side of the symbol "=" so we reverse the sign

- becomes +

and

+ becomes -

Which exponential function is represented by the graph?
Anna [14]

Answer:

Step-by-step explanation:

Let's solve this using our formula for exponential functions:

y=a(b)^x where a is the initial value and b is the growth/decay rate. We will fill that equation in with 2 of the coordinates on the graph and come up with the values for both a and b. (0, 3) and (1, 6):

3=a(b)^0. Anything raised to the power of 0 is 1, so that means that

a = 3. We will use that value along with the x and y from the second coordinate to solve for b:

6=3(b)^1. b to the first is just b, so our equation is

6 = 3b and

b = 2.

Our equation then is

y=3(2)^x, the third choice down.

HELP!! To find the quotient of two fractions, you first need to rewrite the division problem as an equivalent multiplication pro
sergey [27]
1. 5/6

2. 2/3 x 5/6

3. 2/3 x 5/6 = 10/18
Multiply the numerators— 2 x 5 = 10
Multiply the denominators—3x 6= 18

4. 10/18 = 5/9
Find the greatest common factor of 10 and 18 which is 2.
Divide the numerator by 2– 10/2 = 5
Divide the denominator by 2– 18/2 = 9

I hope this helps!
