What is the slope of a line perpendicular to the line whose equation is 3x-7y+14=0?

1 answer:

7 0

1. Find the slope of the given line. Do this by solving <span>3x-7y+14=0 for m:

3x + 14 = 7y, which gives us m = 3/7.

2. Find the slope of a line perpendicular to this one. It's the negative reciprocal of m = 3/7, or -7/3.

-1 + 4x=3x +3<br> Solve for x ?

docker41 [41]

Answer:

$x = 4$

Step-by-step explanation:

1. Regroup terms.

$4x - 1 = 3x + 3$

2. Add 1 to both sides.

$4x = 3x + 3 + 1$

3. Simplify 3x + 3 + 1 to 3x + 4.

$4x = 3x + 4$

4. Subtrect 3x from both sides.

$4x - 3x = 4$

5. Simplify 4x - 3x to x.

$x = 4$

Therefor, the answer is, x = 4.

zhenek [66]

Answer:

10 blocks

Step-by-step explanation

check the image attached, the y coordinate of his school and house are the same that is, -2 so all we have to do is check the distance between x coordinates

that is , -7 and 3

distance between school and his house = 3 - (-7) = 10 blocks

Mrs Smith has 12 times as many markers as color pencils the total number of markers and colored pencils is 78 how many markers d

Ainat [17]

Let the colored pencil amount be p.
Then this is the equation:
12p+p=78
Simplifying, we can see that
13p=78
Divide both sides by 13 to get
p=6

Since there are 12 times as many markers as colored pencils, there are 72 markers.
