Answer:
The slope is -5x
Step-by-step explanation:
To find the slope, you do rise/run. So to get from one point to the other, you would move 5 units down, and 1 unit to the right.
It can be written as -5/1 or -5.
Hope this helps!
The formula to start with is (DC +CE) * CE = (AB + BE) * BE
Replace the letters with the numbers and equations:
(1 + x+4) * x+4 = (11 + x+1) * x+1
(x+5) * (x+4) = (x+12) * (x+1)
x^2 + 9x +20 = x^2 +13x +12
x^2 = x*x = 2x
11x+20 = 15x+12
20 = 4x+12
8 = 4x
x = 8/4
x = 2
Answer:
100
Step-by-step explanation:
So he expected 20 guest but 5 <em>TIMES</em><em> </em>as many showed up
20*5=100
Yes they are because you use distributive property and 4(x+y) you have to do 4•x= 4x and 4•y=4y so it would be 4y+4x
