I need help with math I tried my best but couldn’t get it

Mathematics
1 answer:
notsponge [240]4 years ago

Answer:

Step-by-step explanation:

1. Convert to slope intercept form (y=mx+b)

2. Find slope (the 'm' in mx)

3. Find slope of perpendicular line

So for the first question:

Convert to slope Intercept form if necessary:

3x+4y=12

4y=12-3x<<Subtract by 3x

y=3-<u>3/4</u>x<<Divide by 4

Find slope

y=3-<u>3/4</u>x

3/4 is the slope

Find slope of perpendicular line

To find the slope of a perpendicular line, you just have to take the reciprocal of the original slope and take the opposite sign.

Here is what I mean:

3/4<<original slope

4/3<<reciprocal

-4/3<<opposite

So for the first question -4/3 is the answer.

Now you can do the rest! Hope this helps!

(If you have more questions feel free to comment to let me know!)

Does anyone know how many ways you can make 16 and 19 on a grid
sasho [114]
You can look for the number 16 on the x-axis. (bottom line) and put a finger there. Then, look for 19 on the y -axis (left line) and put a finger there. Trace your left finger to the right and your right hand up until they meet. That is (16,19)

3x - 6 = 2 - 5x how do i get x
Elanso [62]

Answer:

x=0.875

Step-by-step explanation:

3x-6=2-5x

Add 6 on both sides (6+2)

2x=8-5x

Add 5x on both sides

7x=8

Divide 7 from both sides

x=0.875

17) x-8=11

18) 9-x=5

19) x+6=7

20) x+(-4)=-18

Step-by-step explanation:

17) The difference between a number and 8 is 11

Let number = x

then the equation will be:

x-8=11

Solving:

x-8=11

x=11+8\\x=19

18) Nine less than a number is five.

Let number = x

then the equation will be:

9-x=5

Solving:

9-x=5\\-x=5-9\\-x=-4\\x=4

19) Seven is equal to a number plus 6

Let number = x

then the equation will be:

x+6=7

Solving:

x+6=7\\x=7-6\\x=1

20) The sum of a number and -4 is -18

Let number = x

then the equation will be:

x+(-4)=-18

solving:

x+(-4)=-18\\x-4=-18\\x=-18+4\\x=-14
