-20 - (-8) = -12
-12 - (-3) = -9
-12/-9 = -4/-3
slope= -4/3
8 boys, x girls, 4 pencils each, total number of pencils 52.
The equation can be 4(8+x) = 52
So lets solve:
4(8+x)=52
Divide 4 on both sides:
8 + x=52 / 4
8 + x = 13
Subtract on both sides:
x = 13 - 8
x = 5
There are 5 girls in the class.
Now lets solve to double check:
4(8+5)=52
4(13)=52
52 = 52
Yes!
This means that there are 5 girls in the class.
I hope this helps! :)
Answer:
negative
Step-by-step explanation:
we know this because a negative divided by a positive is a negative
Answer:
x = -3
Step-by-step explanation:
<em>f(x) = -4</em> which you plug in for <em>f(x)</em> = 5x+11
this gets you -4 = 5x+11
subtract 11 from both sides
-15 = 5x
divide 5 on both sides
-3 = x
Answer:
The equivalent expression is 10x-6.
