Answer:
y = 2x - 10
Step-by-step explanation:
y2 - y1/ x2 - x1
0 - 2 / 5 - 6
= 2
y = 2x + b
2 = 2(6) +b
2 = 12 + b
-10 = b
The equation is y = 2x - 10

Answer:
June, Mitchell and Nick are the ones who drew the line of symmetry correctly because if you were to cut that in half, both sides remain the same shape and size. Stephanie, Liz, and Brandon are wrong because if you cut that you get different shapes and sizes, they will not be identical.
Answer:
June did
Step-by-step explanation:
Symmetry is when both side are the EXACT SAME!!! June is the only one who has done it correctly

Gloria, Teresa, and Rebecca went to an office supply store. Gloria bought 8 pencils, 4 markers, and 6 erasers. Her total was
$22.00. Teresa spent $19.25 buying 5 pencils, 7 markers, and 8 erasers. Rebecca bought 5 pencils, 5 markers, and 4
erasers for $15.75. What is the cost of each item?
Answer:
pencil: $2
marker: $0.75
eraser: $0.5
Step-by-step explanation:
Let the prices of one pencil, one marker, and one eraser be p, m, and e, respectively.
Gloria:
8p + 4m + 6e = 22 Eq. 1
Teresa:
5p + 7m + 8e = 19.25 Eq. 2
Rebecca:
5p + 5m + 4e = 15.75 Eq. 3
Subtract Eq. 3 from Eq. 2:
2m + 4e = 3.5 Eq. 4
Multiply Eq. 2 by 8 and subtract from it Eq. 1 multiplied by 5.
40p + 56m + 64e = 154 Eq. 2 times 8
(-) 40p + 20m + 30e = 110 Eq. 1 times 5
----------------------------------------
36m + 34e = 44
18m + 17e = 22 Eq.5
Now use Equations 4 and 5 as a system of two equations in two variables.
Multiply Eq. 4 by 18. Subtract Eq. 5 from it.
36m + 72e = 63
(-) 36m + 34e = 44
-----------------------------
38e = 19
e = 19/38
e = 0.5
Now substitute e = 0.5 into Eq. 4 to fond m.
2m + 4e = 3.5
2m + 4(0.5) = 3.5
2m + 2 = 3.5
2m = 1.5
m = 0.75
Substitute e = 0.5 and m = 0.75 into Eq. 1 to find p.
8p + 4m + 6e = 22
8p + 4(0.75) + 6(0.5) = 22
8p + 3 + 3 = 22
8p = 16
p = 2
Answer:
pencil: $2
marker: $0.75
eraser: $0.5
The cost of each of the items are: cost of pencil = $2, cost of marker = $ 3 / 4 and cost of eraser = $ 1 / 2
let
the cost of pencil = x
the cost of marker = y
the cost of eraser = z
How to form the equation to calculate cost of each itemGloria bought 8 pencils, 4 markers, and 6 erasers. Therefore,
8x + 4y + 6z = 22
Teresa spent $19.25 buying 5 pencils, 7 markers, and 8 erasers. Therefore,
5x + 7y + 8z = 19.25
Rebecca bought 5 pencils, 5 markers, and 4 erasers for $15.75. Therefore,
5x + 5y + 4z = 15.75
Let'a combine the equation
8x + 4y + 6z = 22
5x + 7y + 8z = 19.25
5x + 5y + 4z = 15.75
Therefore,
x = 2, y = 3 / 4 and z = 1 / 2
Therefore, the cost of each item are as follows;
cost of pencil = $2
cost of marker = $ 3 / 4
cost of eraser = $ 1 / 2

The diameter of the logo at the center of a basketball court is 10 feet. What is the area of the logo?
Answer:
≈78.539816 ft²
≈78.54 ft²
Step-by-step explanation:
Since the logo is in the shape of a circle, the area can be found with the formula:
πr²To find r, divide the diameter of the circle by 2 (r stands for radius, the length from the center of the circle to the edge):
10÷2=5Now that all variables are known, complete the equation to find the area:

You are a first year police officer in Swanton, Ohio.
You are earning a monthly
salary of $4718.
Next year you will be given a raise to $62147 annually.
How much more per month will you earn your second year?
Answer:
$460.92
Step-by-step explanation:
First year monthly salary = $4,718
Second year annual salary = $62,147
Second year monthly salary = Annual salary / 12
= $62,147 / 12
= $5,178.92
How much more per month will you earn your second year?
Amount of increase in second year monthly salary = Second year monthly salary - First year monthly salary
= $5,178.92 - $4,718
= $460.92
The graph of linear function f passes through the point (1, -6) and has a slope of 3. What is the zero of f?
Answer:

What is 11/12 + 2 1/6 ?
Either decimal or fraction.
Answer:
3.0833
Step-by-step explanation:
i dont know how many 3's
Answer: 37/12
Step-by-step explanation: First you must turn 2 1/6 into a improper fraction, so 2x6 + 1 will get you 13 as the numerator and the denominator will be 6 so now we have 13/6 + 11/12. Now we must turn the denominator for 13/6 into 12 so, 13x2/6x2 so it is 26/12 so now the equation is 26/12 + 11/12 is 37/12.
Find the midpoint of the line on the coordinate plane with the given endpoints below.
(-1, 1), (5, -5)
Answer:
Then the midpoint is (2, -2)
Step-by-step explanation:
We treat the x- and y-coordinates separately, first finding the average (mean) of the x-coordinates and then the average of the y-coordinates:
xm = (-1 + 5)/2 = 2
ym = (1 - 5)/2 = -2
Then the midpoint is (2, -2)
Answer:
(2,-2)
Step-by-step explanation:
Two points are given to us and we need to find the midpoint of those two points. The points are
(-1,1) and (5,-5) . Let us say we have two points ( x1,y1) and ( x2 , y2) . The midpoint will be ,
[tex]\implies Midpoint =\bigg( \dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2} \bigg) \\\\\implies Midpoint = \bigg( \dfrac{-1+5}{2},\dfrac{1-5}{2}\bigg)\\\\\implies Midpoint = \bigg( \dfrac{4}{2},\dfrac{-4}{2}\bigg)\\\\\implies \red{Midpoint = ( 2 , -2) }[/tex]
The manufacturer of a certain brand of aluminum foil claims that the amount of foil on each roll follows a Normal distribution with a mean of 250 ft2 and a standard deviation of 2 ft2. To test this claim, a restaurant randomly selects 10 rolls of this aluminum foil and carefully measures the mean area to be ¯ = 249.6 ft2
Find the probability that the sample mean area is 249.6 ft2 or less if the manufacturer’s claim is true
Answer:
Given that the manufacturers claim is true, the probability that the sample mean area is 249.6 ft.² or less is 0.42074
Step-by-step explanation:
The manufacturer claims that mean amount of foil on each roll, μ = 250 ft²
The standard deviation of the measured amount of foil per roll, σ = 2 ft.²
The number of rolls tested by the restaurant, n = 10 rolls
The mean measured by the restaurant, [tex]\overline x[/tex] = 249.6
Taking the sample means as individual score, we have;
The z-score, of the sample mean is given as follows;
[tex]z=\dfrac{\overline x -\mu }{\sigma }[/tex]
At [tex]\overline x[/tex] = 249.6, we have;
z = (249.6 - 250)/2 = -0.2
Therefore, the probability for a mean less than or equal to 249.6, we have;
The probability, P = P(z < -0.2) = 0.42074
The probability that the sample mean area is 249.6 ft.² or less given that the manufacturers claim is true, P = 0.42074.
