Answer:
use the formula for a line through two points
[tex]y - y_{1} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} \times (x - x_{1})[/tex]
plug in the given points:
[tex]y - 7 = \frac{15 - 7}{5 - 1} \times (x - 1)[/tex]
[tex]y = \frac{8}{4} \times (x - 1) + 7[/tex]
[tex]y = 2 \times (x - 1) + 7 \\ y = 2x - 2 + 7 \\ y = 2x + 5[/tex]

How to round 13294 to the nearest ten,to the nearest hundred, to the nearest thousand and to the nearest ten thousand
Answer:
Ten, 13290 Hundred, 13300 Thousand, 13000 Ten Thousand, 10000
Step-by-step explanation: If the number to the right of the number you are rounding lets say 6969 in the tens place 6, to the right of that six is a nine which is larger than 5 (when rounding if a number is 5 and up you round it up if its 4 and lower let it stay the same) so it would be 6970 because everything to the right of it as including the number you are rounding it up/down because of it turs to a zero

O 96 m
O
76 m 2
72 m 2
86 m 2
9514 1404 393
Answer:
86 m^2
Step-by-step explanation:
The figure is equivalent to a rectangle that is 8 m by 12 m, with a triangle cut off. The width of the triangle is (12 m-8 m) = 4 m. The height of the triangle is (8 m-3 m) = 5 m.
Then the figure's area is ...
A = LW - (1/2)bh
A = (12 m)(8 m) -(1/2)(4 m)(5 m) = 96 m^2 -10 m^2
A = 86 m^2
The area of the figure is 86 square meters.

7 Henri Plans to sell cups of coffe at his school sports event
Henri has a hot water Container that holds 16 litres.
He needs about 200ml of hot water for each cup of coffee
a How many cups of coffee can he make from a full bottle of
water. Hens will charge 80 cents per cup of coffee he hopes
to sell 250 Cups of coffee
How
many
full Containers of water will he use.
How much mony will he make ?
Quantity of water with Henri = 16 litres
Quantify of water he will need for one cup of coffee = 200 ml
Number of cups of coffee he can make with a full cup of water :-
[tex] = 16 \: litres \: = 16000 \: ml[/tex]
[tex] = \frac{16000}{200} [/tex]
[tex] = 80 \: cups \: of \: coffee[/tex]
So , Henri can make 80 cups of coffee with one full bottle of water .
Quantity of water needed to make 80 cups of coffee = 16,000 ml
Quantity of water needed to make one cup of coffee :-
[tex] = \frac{16000}{80} [/tex]
[tex] = 200 \: ml[/tex]
So , 200 ml of water is needed to make one cup coffee .
Quantity of water he needs to make 250 cups of coffee :-
[tex] = 200 \times 250[/tex]
[tex] = 50000 \: ml[/tex]
So , Henri needs 50,000 ml of water to make 250 cups of coffee .
Number of water containers he will use :-
[tex] = \frac{50000}{16000} [/tex]
[tex] = 3.125 \\ = 3 \: water \: containers[/tex]
So , Henri will use 3 full water containers to make 250 cups of coffee .
Money charged per one coffee = 8 cents
Money charged for 250 coffees :-
[tex] = 250 \times 8[/tex]
[tex] = 2000 \: cents[/tex]
So , Henri will make 2000 cents if he sells 250 cups of coffee .
Therefore , Henri will use 3 full containers of water to make 250 cups of coffee and he he will make 2000 cents by selling 250 cups of coffee .

Is 21, 28,35 the sides of a right triangle?
Answer:
yes
Step-by-step explanation:
divide each by 7 =
21/7 = 3
28/7 =4
35/7 = 5
3,4,5 are always a perfect triple, and multiples of 345 are perfect triples as well. Therefore, they are sides of a right triangle.

What is the domain for the piece of the function
represented by f(x) = x + 1?
Answer:
[tex]x > 1[/tex]
if you graph
[tex]f(x) = x + 1[/tex]
you'll see that it's that part of graph from x=1 to right and x=1 on this graph is not ncluded so it's x>1
Which of the following variable expressions would represent the area of a rectangle if its length was represented by x+5 and its width was represented by x-2?
x[tex]x^{2} +3x+10\\
x^{2} +3x-10\\
x^{2} -10x+3\\
x^{2} -10[/tex]
Answer:
B
Step-by-step explanation:
Remember that the area of a rectangle is given by the formula [tex]A=lw[/tex].
We know that the length is [tex](x+5)[/tex] and the width is [tex](x-2)[/tex]. Therefore, the area will be:
[tex]A=(x+5)(x-2)[/tex]
Expand. Use the Distribute Property. This yields:
[tex]A=(x+5)(x)+(x+5)(-2)[/tex]
Multiply:
[tex]A=(x^2+5x)+(-2x-10)[/tex]
Combine Like Terms:
[tex]A=x^2+(5x-2x)-10\\A=x^2+3x-10[/tex]
Therefore, our answer is B.
