Point A is at (3, - 8) and point B is at (7, 3)

What is the midpoint of line segment overline AB ?

Please help

Answer:

(1, - 2)

Step-by-step explanation:

2x - y = 4

3x + y = 1

A = [tex]\left[\begin{array}{cc}2&-1\\3&1\end{array}\right][/tex] = 2(1) - 3( - 1) =2 + 3 = 5

[tex]A_{x}[/tex] = [tex]\left[\begin{array}{cc}4&-1\\1&1\end{array}\right][/tex] = 4(1) - 1(- 1) = 4 + 1 = 5

[tex]A_{y}[/tex] = [tex]\left[\begin{array}{cc}2&4\\3&1\end{array}\right][/tex] = 2(1) - 4(3) = 2 - 12 = - 10

x = [tex]\frac{A_{x} }{A}[/tex] = 1

y = [tex]\frac{A_{y} }{A}[/tex] = - 2

Answer:

Mae Ling will make $679.5 in a week if she sells 4300 worth of merchandise.

Step-by-step explanation:

Given that

Weekly salary of Mae Ling = $400

Commission rate = 6.5%

Mae ling's total weekly earning will be her salary plus her commission on the sales she does in the week.

Given that her sales for the said week are: $4300

Her commission will be:

[tex]Commission = 6.5\%\ of\ sales\\ = 0.065*4300\\=\$279.5[/tex]

Now to calculate her total salary, we will add the weekly salary and commission.

[tex]Total\ weekly\ Earning = Weekly\ Salary +\ Commission\\= \$400+\$279.5\\=\$679.5[/tex]

Mae Ling will make $679.5 in a week if she sells 4300 worth of merchandise.

B: 6

Answer:

i) 60 trees

ii) 3600 apples

Step-by-step explanation:

50 trees per acre

Total pounds produced per acre ( ideally ) = 70 * 50 = 3500 pounds

Assumption :

lets assume the additional tree = X

Therefore the number of trees planted per acre = ( 50 + x )  where x ≤ 30

calculate average yield per tree =   ( 70 - x )

Total yield per acre = number of trees * average yield per tree

                                 = ( 50 + x ) * ( 70 - x )

                           Y(x)   =  3500 + 20x - x^2

i) Number of trees that should be planted per acre to obtain maximum yield per acre

y'(x) = 20 - 2x = 0   hence X ( number of additional trees ) = 20 / 2 = 10

Number of trees that should be planted per acre = 50 + 10 = 60 trees

ii) Calculate maximum yield

where ; X = 10

number of trees planted per acre = ( 50 + x ) = 50 + 10 = 60

hence maximum yield  = ( 50 + x ) * ( 70 - x ) = ( 60 ) * ( 60 ) = 3600 apples

Answer:

3 3/18

Step-by-step explanation:

5 3/6-2 1/3

We first need to turn our mixed numbers into fractions by multiplying the while number by the denominator, then adding the numerator. When we do this, 5 3/6 turns into 33/6 and 2 1/3 turns into 7/3. Now we have this:

33/6-7/3

Now we need to find the Least common multiple of the denominators in order to find our common denominator, which in this case is 6. 33/6 already has a denominator of 6, so we do not need to do anything to it. To give a denominator of 6 to 7/3, however, we must multiply by 2, giving us this:

33/6-14/6

Now we can subtract the numerators.

19/6

To turn this back into a mixed number, we divide 19 by 6, which gives us 3 with a remainder of 1. Therefore, our answer is 3 1/6. This is an equivalent fraction to the fourth answer, 3 3/18.

Answer:

Percentage decrease= 21.86%

Step-by-step explanation:

Giving the following information:

Selling price per unit= $2.65

Current variable cost= $0.82

Increase in variable cost= $0.4

To calculate the unitary contribution margin, we need to use the following formula:

Unitary contribution margin= selling price - unitary variable cost

Unitary contribution margin= 2.65 - 0.82

Unitary contribution margin= $1.83

New contribution margin= 2.65 - 1.22

New contribution margin= $1.43

Finally, the percentage decrease:

Percentage decrease= [1 - (1.43/1.83)]*100

Percentage decrease= 21.86%

Answer:

$57.38

Step-by-step explanation:

The total bill is $45.90.

They decided to tip the waiter 25%.

Therefore, the total amount they leave will be the total bill plus the amount they will tip.

They amount they tipped is 25% of the total bill. Therefore, the tip is 0.25(45.9) or approximately $11.48 (rounded up).

So, the amount they will leave is the original amount plus the tip. So, in total, they left:

$45.90+$11.48 or $57.38

Answer:

57.38

Step-by-step explanation:

percent means per one hundred, or 1/100.

25%=25/100

45.90 times 25/100= 11.475

Since money doesn't have a thousandthes digit, I just rounded it up to 11.48.

11.48+45.90=57.38

Another way you could do it would be to just mutiply 45.90 by 125/100 to get 57.375, which rounds to 57.38.

Answer:

B. [tex] n = \frac{1}{3} [/tex]

Step-by-step explanation:

If ∆FGH ~ ∆F'G'H', then their corresponding side lengths would be proportional. This means:

F'G'/FG = G'H'/GH = F'H'/FH = n

The ratio of any of their corresponding side lengths will give you the value of n.

Therefore:

n = F'G'/FG

F'G' = 5

FG = 15

Thus,

[tex] n = \frac{5}{15} [/tex]

[tex] n = \frac{1}{3} [/tex]

The scale factor which is a fraction implies that the size of ∆FGH was reduced after dilation.

Answer:

I think the answer would be 125 iPhones.

Step-by-step explanation:

So basically the question is what is 2.5% of 5000.

Just multiply 5000 * 0.025 = 125

It is false that the expressions 4x − 2(5x − 1) and 6x + 2 are equivalent expressions

The expression is given as:

4x − 2(5x − 1)

Open the bracket

4x − 2(5x − 1) = 4x − 10x + 2

Evaluate the like terms

4x − 2(5x − 1) = − 6x + 2

− 6x + 2 and 6x + 2 are not equal expressions

Hence, 4x − 2(5x − 1) and 6x + 2 are not equivalent expressions
