Answer:

5/4 slope

-7 y intercept.

Step-by-step explanation:

The slope is the number in front of the x. The number in front of the x is 5/4. The slope is 5/4

1. The y intercept is whatever is behind the x or 0 if there is no number following the x.  

2. The y intercept is also characterized by being on the same side of the equation as the x.

3. Finally it has no x in it.

In this case the y intercept is -7

Examples

y + 2 = x    2 is not the y intercept. subtract 2 from both sides. y = x - 2. Therefore -2 is the y intercept.

2y = 4x + 6                4 is not the slope. You have to divide by y = 2x+3. So 2 is the slope and 0,3 is the y intercept.

I.) (5x+3)/4-(2x-4)/3=5
Clear fractions:
3·((5x+3)/4)=15x+9
4·((2x-4)/3)=8x-16
15x+9-(8x-16)=5
15x+9-8x+16=5
Combine like terms:
7x+25=5
7x=-20
x=-20/7

II.) (3/11)·(5/6)-(9/12)·(4/3)+(5/13)·(6/15)
Remember PEMDAS
So first multiply:
3/11·5/6=15/66
9/12·4/3=3/3·1/1=3/3=1
5/13·6/15=1/13·6/3=6/39=2/13
(15/66)-1+(2/13)
Combine:
15/66-1/1=15/66-66/66=-51/66
-51/66+2/3=-51/66+44/66=-7/66
Answer: -7/66 :)

What is the answer to -3+p=?
nata0808 [166]
There is not an answer to an expression. 

-3+p is an expression, unless there was an equal sign and a sum at the end, that is when we can solve for the variable x. 

-3+p simply equals -3+p

The sales tax on a surfboard is $12. What is the percent of sales tax?
Rudik [331]
X= sales tax %

Step 1:
$240 * sales tax %= $12
240 * x= 12
240x=12
Divide both sides by 240
x= 0.05 (decimal of the %)


Convert to %:
Multiply decimal by 100 (or move decimal to the right two decimal places
=0.05 x 100
=5 %

The sales tax is 5%.

Hope this helps! :)
