Find the slope and reduce.<br> P=(-8, 3) Q=(-6, 2)<br> Slope
Lyrx [107]

Answer:

-\frac{1}{2}

Step-by-step explanation:

Slope/Gradient = \frac{y1-y2}{x1-x2}

P = (-8 , 3) (x1, y1)

Q = (-6 , 2) (x2, y2)

Slope = \frac{3-2}{-8-(-6)} =\frac{1}{-8+6} = \frac{1}{-2} = -\frac{1}{2}

How do you change 44/15 into a mixed number
torisob [31]
First you can divide 44 into 15, which is two with a remainder of 14 so that means the mixed number would be 2 and 14/15

Can some one help me.
alina1380 [7]

Answer:

x = ± 2, x = 3

Step-by-step explanation:

note that x = 2 gives

2³ - 3(2)² - 4(2) + 12 = 8 - 12 - 8 + 12 = 0

Hence x = 2 is a root and (x - 2) is a factor

x³ - 3x² - 4x + 12 ÷ (x - 2)

= (x - 2)(x² - x - 6)

= (x - 2)(x + 2)(x - 3), hence

(x - 2)(x + 2)(x - 3) = 0

equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x + 2 = 0 ⇒ x = - 2

x - 3 = 0 ⇒ x = 3

The speed of an object in space is shown in the graph.
Arlecino [84]

Answer:

B

Step-by-step explanation:

To find the slope, find the vertical distance and the horizontal distance between the points. Then write the distances as a ratio.

6 - 3 = 3

0.4 - 0.2 = 0.2

The slope is 3/0.2 = 15.

Find the equation of the line passing through the point (2,−4) that is parallel to the line y=3x+2
Naily [24]

Hey there! :)

Line passes through (2, -4) & parallel to y = 3x+ 2

Let's start off by identifying what our slope is. In the slope-intercept form y=mx+b, we know that "m" is our slope. "M" is simply a place mat so if we look at our given line, the "m" value is 3. Therefore, our slope is 3.

We should also note that we're looking for a line that's parallel to the given one. This means that our new line has the same slope as our given line. Therefore, our slope for our new line will be 3.

Now, we use point-slope form ( y-y₁=m(x-x₁) ) to complete our task of finding a line that passes through (2, -4) with a slope of 3.

y-y₁=m(x-x₁)

Let's start by plugging in 3 for m (our slope), 2 for x1 and -4 for y1.

y - (-4) = 3(x - 2)

Simplify.

y + 4 = 3x - 6

Simplify by subtracting 4 from both sides.

y = 3x - 10

~Hope I helped!~
