Answer:

option A

(2,-\frac{3}{2})

Step-by-step explanation:

we know that

The formula to calculate the midpoint M between two points is equal to

M (\frac{x1+x2}{2},\frac{y1+y2}{2})

In this problem we have

(x1,y1)=(2,-7)

(x2,y2)=(2,4)

substitute the values

M (\frac{2+2}{2},\frac{-7+4}{2})

M (\frac{4}{2},\frac{-3}{2})

M (2,-\frac{3}{2})

You buy 3 pairs of pants at an original cost of $24.99 and the sale is buy 1 get the 2nd pair half off. The sales tax is 6%. How
Finger [1]

Answer:

  D.  $66.23

Step-by-step explanation:

The sale discounts your purchase by half the price of a pair of pants, so you pay for 2.5 pairs of pants. The sale price of the pants is then ...

  $24.99 × 2.5 = $62.48

The added tax multiplies this value by 1.06, so you pay ...

  1.06 × $62.48 = $66.23

_____

<em>Comment on the answer</em>

Whether you pay $66.23 or $66.22 depends on how the discount is calculated. If you get the benefit of the half-penny (the discount is rounded up), then the sale price is $62.47 and the total is $66.22.

3x + y = 3
Westkost [7]
If you would like to solve the system of equations, you can do this using the following steps:

3x + y = 3
x + y = 2 ... y = 2 - x
_________________
<span>3x + y = 3
</span>3x + 2 - x = 3
2x = 3 - 2
2x = 1
x = 1/2

y<span> = 2 - x = 2 - 1/2 = 1 1/2 = 3/2

(x, y) = (1/2, 1 1/2) = (1/2, 3/2)

The correct result would be </span><span>C) x = 1/2, y = 3/2.</span>

Vesna [10]
Total money * fraction = part

Please help me. it is not a quiz a homework
OLga [1]

Answer:

3rd graph

Step-by-step explanation:

3m ≥ 21   whenever you see '≤ or ≥' then you know the circle must be filled

divide each side by 3 to isolate 'm':

m ≥ 7  This inequality, when graphed, should have a closed circle on the number 7 and the shading would be to the right because the symbol is indicates all values "greater than" 7
