Answer:

(x,-y): (2,-2)

Step-by-step explanation:

M=(x+x)/2,(y+y)/2

Given (1,4)=

[tex] \frac{3x - 4}{2} [/tex]

This implies:

[tex]1 = \frac{3x - 4}{2} [/tex]

[tex]3x - 4 = 2 \\ 3x = 2 + 4 \\ \frac{3x }{3} = \frac{6}{3} \\ x = 2[/tex]

In a similar way,

[tex]4 = \frac{ - 2 + 5y}{2} \\ - 2 + 5y = 8 \\ 5y = 10 \\ y = 2[/tex]

The question demanded (x,-y)

Hence(2,-2) is the answer

Answer: 3.3

Step-by-step explanation: 5 divided by 3 x 2 = 3.3

Step-by-step explanation:

I think what is meant in the triangle ABC we have the three angles.

the sum of all angles in a triangle is airways 180 degrees.

so,

180 = A + B + C

180 = 42 + B + C

now, we know also that

B = 5×C

so, we can use that above

180 = 42 + 5×C + C

138 = 6×C

C = 138/6 = 23 degrees

B = 5×C = 5×23 = 115 degrees

Answer:

Monthly rent for Year 9: $1,653.5

Total cost of rent for the whole 9th year: $19,841.9

Step-by-step explanation:

Given the monthly rent of $800 for an aparment, for which it is set to increase by 9.5% annually:

The monthly rent will stay at $800 for the first year.  

For year 2, we must add the 9.5% increase in the monthly rent. In order to determine the 9.5%, simply multiply the monthly rent by 0.095 (the decimal equivalent of 9.5%), then add the product to the monthly rent in year 1 of $800.

9.5% increase for Year 2:  $800 × 0.095 = $76

Monthly rent in Year 2:  $800 + $76 = $876

For year 3, we must add the 9.5% increase in the monthly rent from Year 2 ($876).  

9.5% increase for Year 3:  $876 × 0.095 = $83.22

Monthly rent in Year 3:  $876 +  $83.22 = $959.22

For year 4, we must add the 9.5% increase in the monthly rent from Year 3 ($959.22).  

9.5% increase for Year 4:  $959.22 × 0.095 = $91.13

Monthly rent in Year 4: $959.22 +   $91.13 = $1,050.35

For year 4, we must add the 9.5% increase in the monthly rent from Year 4 ($1,050.35).  

9.5% increase for Year 5:  $1,050.35 × 0.095 = $99.78

Monthly rent in Year 5: $1,050.35 + $99.78 = $1,150.13

9.5% increase for Year 6:  $1,150.13 × 0.095 = $109.26

Monthly rent in Year 6:  $1,150.13 + $109.26 = $1,259.39

9.5% increase for Year 7:  $1,259.39 × 0.095 = $119.64

Monthly rent in Year 7:  $1,259.39 + $119.64 = $1,379.03

9.5% increase for Year 8:  $1,379.03  × 0.095 = $131.00

Monthly rent in Year 8:  $1,379.03 + $131.00 = $1,510.04

9.5% increase for Year 9:  $1,510.04  × 0.095 = $143.45

Monthly rent in Year 9:  $1,510.04 + $143.45 = $1,653.50

In order to determine the yearly cost of renting an apartment, simply multiply  monthly rent by 12. In other words:

Year 1: $800 × 12 = $9600

Year 2: $876 × 12 = $10,512

Year 3: $959.22 × 12 = $11,510.64

Year 4: $1,050.35 × 12 = $12,604.15

Year 5: $1,150.13 × 12 = $13,801.55

Year 6: $1,259.39 × 12 = $15,112.69

Year 7: $1,379.03 × 12 = $16,548.40

Year 8: $1,510.04 × 12 = $18,120.50

Year 9: $1,653.50 × 12 = $19,841.94

Therefore, due to the 9.5% annual increase in rent, the monthly cost of an apartment during the 9th year is $1,653.5, or $19,841.9 (12-months' worth of rent).

Answer:

$18.00

Step-by-step explanation:

To find the price of one cup divide 4.00 by 2

4.00/2=2.00

Now that we know the price of one cup of coffe we multiply that to find the price of nine cups of coffee

2.00x9=$18.00

Hope this helps

Answer:

It will cost $18

Explanation:

Marianne is buying 4 bundles of the two large coffees. That's $16 but she still needs to buy her 9th coffee. We can say that one coffee is $2.00 since it cost $4.00 for two coffees. So she'll need to buy one more coffee that will tally up the cost to $18.

Answer:

If a line goes through both points, the slope of that line would be [tex]0[/tex].

Step-by-step explanation:

The slope of a line is equal to the ratio between the vertical change of this line "rise" and the corresponding horizontal change "run":

[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}}\end{aligned}[/tex].

If a non-vertical line goes through two distinct points [tex](x_{0},\, y_{0})[/tex] and [tex](x_{1},\, y_{1})[/tex] where [tex]x_{0} \ne x_{1}[/tex], the vertical change (rise) would be [tex](y_{1} - y_{0})[/tex]. The corresponding horizontal change would be [tex](x_{1} - x_{0})[/tex]. Thus, the slope of that line would be:

[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}}\end{aligned}[/tex].

In this question, [tex]x_{0} = 4[/tex] and [tex]y_{0} = 5[/tex] for the first point, whereas [tex]x_{1} = 3[/tex] and [tex]y_{1} = 5[/tex] for the second point.

The rise (vertical change) of this line from the first point to the second would be [tex](y_{1} - y_{0}) = 5 - 5 = 0[/tex]. The corresponding run (horizontal change) would be [tex](x_{1} - x_{0}) = 3 - 4 = -1[/tex].

Thus, the slope of this line would be:

[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}} \\ &= \frac{5 - 5}{3 - 4} \\&= \frac{0}{-1} \\ &= 0\end{aligned}[/tex].

In other words, the slope of this line is [tex]0[/tex]. Geometrically, a slope with a slope of [tex]0\![/tex] would be horizontal. The vertical coordinate of all points on such line would be the same ([tex]5[/tex] for points on the line in this question.)

Answer:

Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.

18x−21y=24

−18x+10y=−2

Add the two equations.

−11y=22

Divide by -11 to isolate y.

y=−2

Substitute y=−2 into either of the 2 equations, I'll just use the second one.

9x=−9

x=−1
