Solve the equation 3x-4=8-x

solmaris [256]

Answer:

x=3

Step-by-step explanation:

3x-4=8-x(Group like terms)

3x+x=8+4(Add both sides)

4x=12(After adding you will proceed to divide both sides by 4)

x=3(x is 3 because 4 can divide 12 3 times that's why we have x as equal to 3)

I -72 –54 -36 y 25 13 1 What is the y-intercept of the line?

Allisa [31]

Answer:

-23

Step-by-step explanation:

As I increases by 18, y decreases by 12. From the last value in the table, I needs to increase by 2·18 for it to become zero. Hence the y-intercept will be 2·12 less than the last value in the table:

1 - 2·12 = -23 . . . the y-intercept

The population of a certain type of seahorse grew by 13% from year to year.

Gekata [30.6K]

Answer: Exponential function

Step-by-step explanation:

A linear function is the form $f(x)=mx+c$ , where m is the constant rate of change of y with respect to x and c is the y-intercept.

An exponential growth function is in the form $f(x)=A(1+r)^x$ , where r is the rate of growth (generally in percent) and A is initial value.

If the population of a certain type of seahorse grew by 13% from year to year, then the rate of growth is 13% .

Hence it is an exponential equation.
