Point slope form:

m=slope
(x1,y1)
First we need to find the slope using the slope formula:

Given the two coordinates:
<span>(1, 9) and (−1, 11)
Plug them into the slope formula:
</span>

Simplify:

<span>
Now we know that:
m=-1 and the (x1,y1) would be </span><span>(1, 9)
</span>
Now we simply plug in the info:
Final answer: y − 9 = −(x − 1)
Answer:
4
Step-by-step explanation:
The area, a of the room is 8* 5.5
a = 44 sqaure feet
one square foot of tiles are sold in packages of 12
To get the number of packages needed, simply divide the area of the room by 12
This gives:
44/12 = 4
= 3.67 round up to the nearest whole number
= 4
"of" means multiply and "is" means equal
1.
x = 14
x = 14(3) <em>multiply both sides by 3 to isolate "x"</em>
x = 42
2.
x = 14
x = 14(5) <em>multiply both sides by 5 to isolate "x"</em>
x = 70
3.
x = 14
2x = 14(5) <em>multiply both sides by 5 </em>
2x = 70
x = 35 <em>divide both sides by 2 to isolate "x"</em>
4.
x = 14
7x = 14(8) <em>multiply both sides by 8 </em>
7x = 112
x = 16 <em>divide both sides by 7 to isolate "x"</em>
Answers: 42, 70, 35, 16
Answer:
x=4
Step-by-step explanation:
Pentagon's sum of interior angle is 540°
let's add all the given degrees
100+20x+16x+16+140+160-5x=540
Collect like terms
100+16+140+160+20x+16x-5x=540
416+31x=540
31x=540-416
31x=124
x=124/31
x=4```
