Answer:
13.6
Step-by-step explanation:
This is pythagoras theorem its c2 = a2+b2
13 squared + 4 squared is 185
the square root of 185 13.601
then rounded is 13.6
Answer:
y=-3x-5
Step-by-step explanation:
y = mx+b
m= -11 - 1
2 - -2
y=-3x+b
(-2,1) and (2,-11)
is
y=-3x-5
Hope this Helps:)
Answer:
She shaded area?
12 x 10 = 120
6 x 7 = 42
42 divided by 2 = 21
Now we subtract both areas:
120 - 21 = 99 of the shaded region.
Joe's Painting: 20x + 100 = y
Steve's Painting: 15x + 120 = y
x = hours worked
y = total income
We can find when the two equations intersect by making them equal to each other. That means we put an equal sign in the middle. So, it would look something like this:
20x + 100 = 15x + 120
First, we have to move the 100 by subtracting it from both sides.
20x = 15x + 120 - (100)
20x = 15x + 20
Then, we need to move the 15x by subtracting it from both sides.
20 - (15x) = 20
5x = 20
Lastly, we need to divide 5 from both sides.
5x = 20/5
x = 4
Therefore, Joe and Steve would have to work for 4 hours in order for their models to be equal to each other.
