Answer:

(-2,3)

Step-by-step explanation:

Given data

the system of linear equation is presented as

3x+5y=9-----1

2x+3y=5-----2

solve simultaneously

3x+5y=9-----1 X 2

2x+3y=5-----2 X3

subtracting 2 from 1

6x+10y=18

-6x+9y=15

0x+y=3

y= 3

put y= 3 in 1

3x+5(3)=9-----1

3x+15=9

3x= 9-15

3x= -6

x= -6/3

x= -2

Hence the ordered pair is (-2,3)

Solve for 2x^2-4x+5=6

Softa [21]

To solve for a variable, you need to get it (x) by itself.

2x² - 4x + 5 = 6 Subtract 6 from both sides
2x² - 4x - 1 = 0 Plug this into the Quadratic Formula

a = 2 , b = -4 , c = -1
x = $\frac{-b \pm \sqrt{b^2 - 4ac} }{2a}$ Plug in your values
x = $\frac{-(-4) \pm \sqrt{(-4)^2 - 4(2)(-1)} }{2(2)}$ Simplify
x = $\frac{4 \pm \sqrt{16 + 8} }{4}$ Simplify
x = $\frac{4 \pm 2\sqrt{6} }{4}$ Simplify by removing a 2 from every term
x = $\frac{2 \pm \sqrt{6} }{2}$ Simplify by taking the fraction apart
x = $\frac{2}{2} \pm \frac{ \sqrt{6} }{2}$ Change $\frac{2}{2}$ to 1
x = 1 $\pm \frac{ \sqrt{6} }{2}$ Simplify $\frac{ \sqrt{6} }{2}$ to $\sqrt{ \frac{3}{2} }$
x = 1 $\pm \sqrt{ \frac{3}{2} }$

What are the slope and the y-intercept of the line shown in the graph?

malfutka [58]

Answer:

Step-by-step explanation:

The line cuts the y at positive two. The rise over run of the slope is -3/1, or 3.

Just had a test on these kinds of problems and i got 100.
