A line passes through the points (-4,-1) and (4,3). A second line passes through the points (-2,-2) and (2,6). At what point do the two lines intersect

Answers

Answer 1

Answer:

(-2/3 , 2/3)

Step-by-step explanation:

Line 1: (-4,-1) (4,3)

m = (3 - -1) / (4 - -4) = 4/8 = 1/2

equation: (y-3)/(x-4) = 1/2          y-3 = 1/2 x - 2

y = 1/2 x + 1 ....(1)

Line 2: (-2,-2) (2,6)

m = (6 - -2) / (2 - -2) = 8/4 = 2

equation: (y-6)/(x-2) = 2              y-6 = 2x - 4

y = 2x + 2  ...(2)

(2)-(1): 0 = 3/2x + 1

3/2 x = -1            x = - 2/3

y = 1/2 * (-2/3) + 1 = 2/3

First find the lowest common multiple of the denominators which are 12 3 9 and 27 these all go into 108. Next divide 108 by the original denominators for example 108/12 is 9 then times 9 by the numerator which is 5 and you get 45 so the first one is 45/108. Do this for them all and order by the size of the numerator

96 is 3/4 of what number?

Answers

Answer:

72.00

Step-by-step explanation:

3/4 x 96 = 72.00

96 is 3/4 of the number 128 , this we get by forming an equation 3/4 × x = 96 and solving for x.

To find the number that 96 is 3/4 of, you can set up a simple equation. Let's denote the unknown number as "x."

According to the given information, we have the equation:

3/4 × x = 96

To solve for x, we need to isolate it on one side of the equation.

Multiplying both sides of the equation by the reciprocal of 3/4, which is 4/3:

(4/3) × (3/4) × x = (4/3) × 96

On the left side, the 3/4 and 4/3 cancel each other out, leaving just x:

x = (4/3) × 96

Evaluating the right side of the equation:

x = 128

Therefore, 96 is 3/4 of the number 128.

Answer:   slope = 0

Explanation:

Think of y = -4 as y = 0x+(-4)

We see that the equation matches the form y = mx+b

m = 0 = slope

b = -4 = y intercept

Side note: this equation graphs out a horizontal line. All horizontal lines have a slope of 0.
