Help! I'm confused with the point-slope form!

Mathematics

xxMikexx [17]3 years ago

The equation for point-slope is y-yi=m(x-xi).

In your given problems, you would use the given coordinate and plug in the x for xi and the y coordinate for yi. The y and x are left alone ( this is how you solve for y=mx+b).

Ex. #1: (2,2) m=-3

Equation: y-yi = m(x-xi)
y-2 ( y coordinate) = -3(x-2)(the x coordinate).
Simplify y-2 = -3x+6 —> y=-3x+8

Can someone please help me?

Ok so their are 36 people that didn't need gel for there hair. so when you multiply 36 x 5 (because each cut costs 5 bucks) you get an answer of 180. so hold on to that and since their are 16 people that asked for gel you would need to first multiply 5 and 10% which gives you 0.5 so when you multiply 5.5 (because when you multiplied the 10% with the 5 you should get .5) times 16 you should get an answer of 88. when you add 180 with 88 you get an answer of 268. Ur welcome couuld u mark this brainlist plzzzzz

Quadrilateral ABCD ​ is inscribed in this circle.
Sedbober [7]
The answer to this is 65. 

Remember that the angles opposite of each other equal to 180. So a+c=180 and b+d=180. 

First, we solve for x. Since we know that b and d equal to 180, we subtract 148 from 180. 
180-148=32. x=32. 

Then we plug that in the expression for angle a. 
2x+1 becomes 2(32)+1
2*32=64
64+1=65.
a=65

A piece of fabric is 2 yards long Marcus puts one patch at each end of the fabric and at each quarter foot mark how many patches
klio [65]
Conversion.
1 yard = 3 feet

So the fabric has 2 yards. Then the size of the patch is 1/4 foot. 
So the number of patches that Marcus used is..
= 3 * 2
= 6 / (1/4)
= 24 patches.

So a total of 24 patches Marcus used.
