Three possible answers are:
y = 2x-1
y = 5x-1
y = -3x-1

All of them have the same y intercept of -1. The slopes are the only thing that differ.

Any linear equation can be written in the form y = mx+b where
m = slope
b = y intercept

Select all equations that are equivalent to 2x + 2 = 10
snow_tiger [21]

Answer:

6x + 6 = 30

2x = 8

plz give brainlyist

Step-by-step explanation:

6x + 2 = 10

to get the first term to be 6x you need to mulitply by 3 but if you did then the equation would be 6x + 6 = 30 so it is not equivlent      

6x + 6 = 30

if you multiply both side by 3 you get 6x + 6 =  30

2x+8

if you subtract 2 from both sides you get 2x = 8

6x = 10

to get the first term to be 6x you need to mulitply by 3 but if you did then the equation would be 6x + 6 = 30 then if you subtract 6 from both sides you get 6x = 24 so it is not equivlent

Circle the equations that represent quadratic functions a. y=3x+1 b. y=x^2+3 c. y=x^3-3 d. x^2+3y=8
Elena L [17]

Answer:

B. y=x^2+3 \\\\D.$ $x^2+3y=8

Step-by-step explanation:

A quadratic function is a function in which the highest power of the unknown variable is 2.

Formally, a quadratic function is defined as a function of the form:

f(x)=ax^2+bx+c, a\neq 0

From the given options, only B and D has the highest power as 2. Therefore, the equations that represent quadratic functions are:

B. y=x^2+3 \\\\D.$ $x^2+3y=8

Select all of the following that are quadratic equations.​
Nesterboy [21]

Answer:

x^2 -2x = 4x+1

2x^2 +12x = 0

9x^2 +6x -3=0

Step-by-step explanation:

A quadratic equation has the highest power of x being squared

x^2 -2x = 4x+1

2x^2 +12x = 0

9x^2 +6x -3=0

These are all quadratic equations
