Solve the following system of equations and show all work.<br> y = 2x2<br> y =<br> 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 $\left(\frac{1}{2}, 1 \right), (1, 2)$

The perimeter of a triangle is 141 inches. The lengths of the sides are in the ratio 5:12:13. Calculate the length of each side.

Akimi4 [234]

Answer:

One side has length 5x

One side has length 12x

One side has length 13x

Step-by-step explanation:

5x + 12x + 13x = 15

x = 15/(5 + 12 + 13) = 15/30 = 0.5

5(0.5) = 2.5

12(0.5) = 6

13(0.5) = 6.5
