Why did you7 ask a question then anwser it yourself

Step-by-step explanation:

Answer: The other point is (17, -6).

Step-by-step explanation:

Midpoint (x,y) of the line segment joining (a,b) and (c,d) is given by :-

[tex](x,y) =(\dfrac{a+c}{2}, \dfrac{b+d}{2})[/tex]

Here, we need to find the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1).

Let other point be (a,b), then

[tex](7,1)=(\dfrac{-3+a}{2},\dfrac{8+b}{2})\\\\\Rightarrow\ \dfrac{-3+a}{2}=7\ \text{ and }\dfrac{8+b}{2}=1\\\\\Rightarrow\ -3+a = 7\times2 \text{ and } 8+b=1\times2\\\\\Rightarrow\ -3+a=14\text{ and }8+b=2\\\\\Rightarrow\ a=14+3, \ \ \ b= 2-8\\\\\Rightarrow\ a=17, b= -6[/tex]

hence, the other point is (17, -6).

Answer:

32x +20

Step-by-step explanation:

Answer:

32x+20

Step-by-step explanation:

If you use distributive property you would multiply each number by 4. 4 times 8x is 32x and 4 times 5 is 20, and when you put those together you get 32x+20!

I hope this helps, and have a great day!

Answer:

Step-by-step explanation:

Find the complete question below;

Given the height modeled by the function;

h(t) = 5 + 98t-4.9t²

when t = 0

h(0) = 5 + 98(0)-4.9(0)²

h(0) = 5

when t = 5

h(5) = 5 + 98(5)-4.9(5)²

h(5) = 5 + 490 - 122.5

h(5) = 372.5

when t = 10

h(10) = 5 + 98(10)-4.9(10)²

h(10) = 5 + 980 - 490

h(10) = 495

when t = 15

h(15) = 5 + 98(15)-4.9(15)²

h(15) = 5 + 1470 - 1,102.5

h(15) = 372.5

when t = 20

h(10) = 5 + 98(20)-4.9(20)²

h(10) = 5 + 1960 - 4.9(400)

h(10) = 1965- 1960

h(10) = 5

Answer:

77 degrees

Step-by-step explanation:

supplementary angles add up to 180 degrees

subtract 103 from 180 to get 77 degrees

Answer:

C, B

Step-by-step explanation:

Basically to find the slope you take the rise over run. How many squares does the line go up, over how many does it go left or right. As you can see in the diagram, it goes up 2 squares and goes left 1 square, giving the slope 2/1, which is 2.

The slope of a horizontal line is straight, which means it goes up 0, so automatically your answer is zero, because dividing anything by 0 is 0.

Answer:

-4

Step-by-step explanation:

because the line is going from top to bottom it is negative

you take the rise ( the Y value) / the run (the X Value)

the Y and X value can be pulled from any two points

Answer:

1/6+1/3

=3+6/6×3

=9/18

=1/2

Step-by-step explanation:

Hope you find this helpful!

Answer: It does because 1/3 is equal to 2/6. in order to add them, they have to have the same denominator. and if you add 2/6 to 1/6, you get 3/6. 3/6 is also equal to 1/2, if you divide both sides by 3.

Step-by-step explanation:

Step-by-step explanation:

it's a function.

the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

the domain is (1,3,7,8)

the range is (2,4,6,9)

Answer:

$74,750

Step-by-step explanation:

Given that,

The cost of a computer = $65,000 + value added tax at 15%

We need to find the amount the computer actually cost the customer.

Total cost = Cost of computer + VAT at 15%

[tex]=65000+65000\times \dfrac{15}{100}\\\\=\$74,750[/tex]

So, the computer actually cost the customer is $74,750.

Answer: The answer is 0.20

Step-by-step explanation:  To find a scale factor all you need to do is find the ratio of a side on the scaled shape to its corresponding side on the original figure.  We know the bottom of the scaled figure is 0.5 and the same side on the original rectangle was 2.5 so we can just divide like so...

0.5/2.5 = 0.2 which is our correct answer.  I hope this has been of use to you :)  If you have any other questions please do not hesitate to ask!

Answer:

x = 10

Step-by-step explanation:

1/10(x + 130) = -2(3 - x)

x + 130 = -20(3-x)

x + 130 = -60 + 20x

x - 20x = -60 - 130

-19x = -190

x = 10

Answer:

Step-by-step explanation:

the triangles are similar

so as we know

now let's solve it

according to the question

[tex] \frac{24}{30 } = \frac{x + 7}{2x - 10} [/tex]

[tex] \frac{4}{5} = \frac{x + 7}{2x - 10} [/tex]

[tex]4(2x - 10) = 5(x + 7) \: (cross \: multiplication)[/tex]

[tex]8x - 40 = 5x + 35[/tex]

[tex]8x - 5x = 35 + 40[/tex]

[tex]3x = 75[/tex]

[tex]x = 25[/tex]

Step-by-step explanation:

Answer:

21

Step-by-step explanation:

the greatest possible length that the two ribbons would be when the ribbons are divided by their lowest common multiple.

The lowest common multiple of 63 is 3. 63/3 = 21

The lowest common multiple of 42 is 2 = 42/2 = 21
