Answer:
Two points on the graph would be (2,-1) and (4,2).
Step-by-step explanation:
You can choose two random x variables such as how i selected 2 and 4. if you change the variable x to those values you can solve for y or in this case f(x).
EX:
3/2*2-4
6/2-4
3-4
f(x)= -1
Answer:
Tres respuestas posibles son:
2 y 3x^2 + x
2x y 3x + 2
x y 6x + 2
y hay muchas mas.
Step-by-step explanation:
Hay muchas respuestas posibles.
6x^2 + 2x = 2(3x^2 + x) = 2x(3x + 2) = x(6x + 2)
Answer:
3(x+22y)
Step-by-step explanation:
Because three can be taken from both of them
Answer:
-1 and 9
Step-by-step explanation:
To solve the quadratic, factor and set its factors equal to 0. Factoring is the action of breaking up a polynomial into pieces which multiply to make it. The factors are found by multiplying numbers to make C and add to B of
.
Here c = -9 and b = -8. The numbers -9 and 1 multiply to -9 and add to -8. These are the factors (x-9)(x+1).
Set each equal to 0 and solve for x.
x-9 = 0
x = 9
x+1 =0
x = -1
Answer:
answer B: (2,-2)
Step-by-step explanation:
First, write the equations on top of each other:

Then, multiply the the second equation by 2 so that we can use elimination of the y-variable:

Next, use elimination to find the value of "x":

So, your x-value is 2.
Now, substitute your x-value into one of your equations, let's take the second equation, 2x-y=6:

Your y-value is -2.
With all your information gathered, you find that the solution to this system of equation is (2,-2).
