Solve the following system of equations and show all work. y = 2x2 y = 3x -1 (10 points)

dedylja [7]

Answer: $\left(\frac{1}{2}, 1 \right), (1, 2)$

Step-by-step explanation:

We have $y=2x^{2}$ and $y=3x-1$ .

Since both of the equations are set equal to y, we can conclude that:

$2x^2 = 3x-1\\\\2x^{2}-3x+1=0\\\\(2x-1)(x-1)=0\\\\x=\frac{1}{2}, 1$

If $x=\frac{1}{2}$ , then $y=3\left(\frac{1}{2} \right)-1=1$

If $x=1$ , then $y=3-1=2$

Therefore, the solutions are $\left(\frac{1}{2}, 1 \right), (1, 2)$

I need some help with this

marshall27 [118]

[-2 3] times [2
1]

comes out to -2(2)+3(1) = -1. Eliminate the first answer choice, due to
the presence of that -7 instead of -1.

[-2 3] times [0
-3]

comes out to - 9. This matches answer choices #2, #3 and #4.

[3,-4][2
1]

comes out to 6-4, or 2. Matches #2, #3, #4.

[3, -4][0
-3]

comes out to +12, which matches answer choice #4.

Answer choice #4 is the correct one.

Review matrix multiplication if need be. Feel free to ask questions here and now if need be.

2. Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of

Gemiola [76]

Answer:

g(x) = (x + 2)(x − 1)(x − 2)

I picked the first one, because why not. :)

End behavior. This is a positive function; there are no negatives next to any of the xs. There are 3 xs, so it's a cubic; a positive cubic has a down-up end behavior.

Y-intercept. We can either graph this on the calculator/online or work it out algebraically. Multiply together the constants: +2 * -1 = -2, -2 * -2 = 4. So the y-intercept is at y = 4. (0,4). I've also attached the graph.

Zeros / x-intercept. This is really simple: set g(x) equal to 0, separate these three parenthesis (x+2) (x-1) and (x-2) into three equations by the Zero Product Property.

x+2 = 0

x = -2

x-1 = 0

x = 1

x-2 = 0

x = 2

So the function has three zeros at (-2,0) (1,0) and (2,0).
