The answer is the 3rd one
Answer:
<u>$33.25</u>
Step-by-step explanation:
Taking Eric's hours as a ratio to the total hours :
- 3.5 : 3.5 + 2
- 3.5 : 5.5
- 3.5 x 2 = : 5.5 x 2
- 7 : 11
Multiply the ratio into the amount paid :
- 52.25 x 7/11
- 4.75 x 7
- <u>$33.25</u>
<u></u>
Eric's share of the money is <u>$33.25</u>
Answer:
The answer is
<h2>( 4 , - 1)</h2>
Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(2,-4) and (6,2)
The midpoint is
We have the final answer as
<h3>( 4 , - 1)</h3>
Hope this helps you
So first one
'how many solutions does 2x-y=-5 and 2x+y=5 have?'
add and get
2x-y-5
plus
2x+y=5
equals
2x+2x+y-y=5-5
4x=0
x=0 always
solve for y
4(0)+y=5
y=5
the solution is (0,5)
only <u>ONE </u>solution
one way is to subsitute
just remember that it is in (x,y) form so
the pont (1,2) means that 1 solution is x=1 and y=2 so subsitute and find that
the first one is the answer you are correct
just look at the graph
the solution is the intersection
it seems to be at a point that is 3 units to the right and -6 units up (6 units down)
so the solution is (3,-6)
yo are corect
subsitution
y=y
therefor
the answe ris (-4,-14) if you did the math correctly
#8 is correct
# 9 is correct
# 10 the answe ris bananas=0.40 pears=0.60
the last one you got it wrong, remember to check your answer to the graph for commonsense
then answer is (-2,5) and (1,2)
