Answer:
y=1
Step-by-step explanation:
we know that the equation of the line is:
y=mx+b
m= slope= (y2-y1)/(x2-x1)
we have two points giver from the graph:
point 1: (-4,1)
point 2: (2,1)
we to find the slope:
m=(1-1)/(2-(-4))
so we have m=0
we need to find "b"
using the point (2,1)
we have:
1=0x+b
so we have b=1
finally we have
y=0x+1
so y =1
<h3>
Answer: B) 11x^2</h3>
Explanation:
Choice A combines to 11x since the 8+3 simplifies to 11.
Choice D is a very similar story. Think of having 8 boxes, which we denote in shorthand as 8x. Then adding on 3 more boxes leads to adding on 3x. Having 8 boxes plus another 3 boxes gives 8+3 = 11 boxes total. So that's why 8x+3x = 11x. Alternatively, we can factor out the x to say 8x+3x = (8+3)x.
This shows choices A,C, and D are equivalent expressions. Choice B is the odd one out.
Answer:
tripling the height (8.4 ft) will triple the volume of the barrel (from 857.39 to 2,572.17)
Step-by-step explanation:
12 boys 3 boys
------------- reduces to ------------
16 girls 4 girls
We want the simplified ratio of girls to students. There are 12+16, or 28, students to start with. We must reduce 16/28, which is the ratio of girls to students before simplification. This reduces to 4/7 (4 to 7).
D= 0.25 days Because 6 hours is 25% of one day
