According to my geometry notes two planes intersect at a line. Hope that helps:)
Answer:
<h2><u><em>
x = -18</em></u></h2>
Step-by-step explanation:
X=20=-x+2 can you solve this?
assuming that the equation is:
20 = -x + 2
x = -20 + 2
x = -18
------------------
First, lets do all calculations in kg. 1kg=1000 grams
Lets set 1 cat's mass as x.
Lets set the other cat's mass as y.
1) x+y=11
2) y=x+1.5
Lets plug eq 2 into eq 1.
x+x+1.5=11
2x+1.5=11
2x=9.5
x=4.75 kg
If one cat weighs 4.75 kg, then the other must weigh 6.25 kg.
Answer:
slope: -1
y-intercept: 6
Step-by-step explanation:
y-intercept is when x is 0 so it's 8 and the slope can be found using the slope formula (y2-y1)/(x2-x1)
(6-8)/(0 - (-2)) = -2/2 = -1
Answer:
-2w
Step-by-step explanation:
If you distribute w with 1 and 3 you will get 1w - 3w. Since the variables are the same, then you subtract 1w from 3w which will give you -2 as the answer.
