Find 1% of the number.

55% = 30

Point (-1, 3) lie on a line with a slope of 4, what is the equation of the line?
sukhopar [10]

Answer: y-3=4(x+1) in point-slope form and y=4x+7 in slope intercept form

Step-by-step explanation:

You can find the point-slope form by plugging the numbers into the following: y-y₁=m(x-x₁).

You will end up with y-(3)=(4)(x-(-1)) which when simplified equals y-3=4(x+1).

To find slope intercept form you know need to isolate y and simplify.

Adding 3 to both sides results in y=4(x+1)+3.

If you then distribute you get y=4x+4+3 which simplifies to y=4x+7.

Solve the following equation, answer as a reduced, mixed number.<br><br> 4(3 - 2x) = 15
Inessa05 [86]
Start by distributing the 4:
12-8x=15
Add 8x to both sides of the equation and subtract 15 from both sides:
8x=-3
divide both sides by 8 to get the value of x:
x=-3/8
