Answer:

OPTION A: 2x + 3y = 5

Step-by-step explanation:

The product of slopes of two perpendicular lines is -1.

We rewrite the given equation as follows:

2y = 3x + 2

⇒ y = $ \frac{3}{2}x + 1 $

The general equation of the line is: y = mx + c, where 'm' is the slope of the line.

Here, m = $ \frac{3}{2} $.

Therefore, the slope of the line perpendicular to the line given = $ \frac{-2}{3} $ because $ \frac{3}{2} \times \frac{-2}{3} = -1 $.

To determine the equation of the line passing through the given point and a slope we use the Slope - One - point formula which is:

                                  y - y₁ = m(x - x₁)

The point is: (x₁, y₁) = (-2, 3)

Therefore, the equation is:

y - 3 = $ \frac{-2}{3} $(x + 2) $

⇒ 3y - 9 = -2(x + 2)

⇒ 3y - 9 = -2x - 4

⇒ 2x + 3y = 5 is the required equation.

Multiply: (5x - 2)(4x^2 - 3x -2)
malfutka [58]

Option B.

5x−2)(4x^2−3x−2)

=(5x+−2)(4x^2+−3x+−2)

=(5x)(4x^2)+(5x)(−3x)+(5x)(−2)+(−2)(4x^2)+(−2)(−3x)+(−2)(−2)

=20x^3−15x^2−10x−8x^2+6x+4

=20x^3−23x^2−4x+4

Graph the system of equations: <br> y=-x^2+3x-1<br> 2y-1=x
Nana76 [90]
Y = -x² + 3x - 1
x = 2y - 1

  x = 2(-x² + 3x - 1) - 1
  x = 2(-x²) + 2(3x) + 2(-1) - 1
  x = -2x² + 6x - 2 - 1
  x = -2x² + 6x - 3
<u>- x              - x      </u>
  0 = -2x² + 5x - 3
  x = <u>-(5) +/- √((5)² - 4(-2)(-3))</u>
                        2(-2)
  x = <u>-5 +/- √(25 - 24)</u>
                   -4
  x = <u>-5 +/- √(1)
</u>              -4
  x = <u>-5 +/- 1</u>
             -4
  x = <u>-5 + 1</u>   or  x = <u>-5 - 1</u>
           -4                    -4
  x = <u>-4</u>              x = <u>-6</u>
        -4                    -4
  x = 1               x = 1.5

2y - 1 = x
2y - 1 = 1
<u>   + 1  + 1</u>
     <u>2y</u> = <u>2</u>
      2     2
       y = 1
 (x, y) = (1, 1)
or
2y - 1 = x
2y - 1 = 1.5
<u>    + 1 + 1    </u>
     <u>2y</u> = <u>2.5</u>
      2      2
       y = 1.25
 (x, y) = (1.5, 1.25)
The two solutions is equal to (1, 1) and (1.5, 1.25).

Find the m, b, and write the equation for the following graph:
Tcecarenko [31]

Answer:

y = 3, m=0, b=3

Step-by-step explanation:

Hi there! If you look at the graph, we have a horizontal like crossing through y=3. your m value will be 0 as there is no slope. For your b value, it will be 3 as the y-intercept is 3.

I hope this helps!
