Answer:
the first 3 is 10 times the value of the second 3
5x^2 (5x^2 - 3x - 1) = 25x^4 - 15x^3 - 5x^2
Answer:
You just need to put the given value of x-input in function f(x)=2x²+6x-8 to get y-output
First, you will start with distributive property. on the right side you will distribute 4 into x and 3.
the equation will become:
2x + 22 = 4x + 12
then you have to get x on only one side of the equal sign. subtract 2x from 4x and the equation becomes:
22 = 2x + 12
subtract 12 from 22:
10 = 2x
divide 10 by 2:
5 = x
or
x = 5

Answer:
Hello There. ☆~\---___`:•€`___---/~☆ The correct answer is C. Both (1,3) and (-2,-4).
To check whether (-2,-4) is a solution of the equation let's substitute x= -2 and y= -4 into the equation:
-7x+3y=2
-7*(-2)+3*(-4)=2
14-12=2
2=2
Do the same thing with (1,3)
-7x + 3y = 2
-7 * 1 + 3 * 3 = 2
-7 + 9 = 2
2 = 2.
Hope It Helps!~ ♡
