How many solutions does the system have? y=−2x−4 y=3x+3

Answers

Answer:

One Solution

Step-by-step explanation:

First substitute the y in the first equation with the second equation to get

-2x-4=3x+3

since theres a variable of both sides, you subtract the variable with the least coefficient, in this case, you add 2x to both sides to get

-4=5x+3

subtract the constant on both sides to get

-1=5x

divide both sides by 5

x= -0.2 or -1/5

One solution, I’m sorry if this is wrong but I remember studying this so I’m hope I’m right!

A student says that the graph of the equation y=3(x+8) is the same as the graph of y=3x, only translated upwards by 8 units. do you agree? why or why not??

Answers

Answer:

agree

Step-by-step explanation:

because they have the same slope of 3. so they are parallel with different y intercepts

Answer:

You don't agree because the equation is y = 3x and f(x) = 3x

Step-by-step explanation:

You would not agree because y = 3x would essentially be a line starting at 0 and going up by 3 whereas

Y = 3(x+8) the graph would start at (0, 24) first point and the second would be (-8,24)
