Is (-2, 6) a solution to this system of linear equations? (HINT: Substitute x
with-2 and y with 6 in both equations, then simplify). *
Answer:
1st Equation: -8x + y = 22
At (-2,6)
(-8*-2)+ 6 =16+6= 22: That is correct
2nd Equation: -8x - y =10
At (-2,6)
(-8*-2)-6= 16-6= 10: That is correct
Both are correct.
Hope it helps you.

Step-by-step explanation:
A pattern is made from four congruent squares.
The sides of the squares are parallel to the axes.
N
Point A has coordinates (3, 2)
YA
B (27, 30)
Point B has coordinates (27, 30)
Point C is marked on the diagram.
Work out the coordinates of C.
Answer:
(13, 16)
Step-by-step explanation:
Point A has coordinates (3,2) Point b has the coordinates (27,30)
Therefore the width of the diagram = 27 - 3 = 24 units and the height of the diagram = 30 - 2 = 28 unit
The length of the square = 28 unit / 4 square = 7 unit
Also, half of the height of the diagram = 28/2 = 14 unit
Therefore the x coordinate is given by:
27 - (2 × 7) = 27 - 14 = 13 or 27 - 14 (=13) or 3 + 7 + (24 - 3 × 7) = 13
Also, the y coordinate is given by:
30 - (2 × 7) = 30 - 14 = 16 or 30 - 14 (=16) or (30 + 2)÷2 = 16
Therefore the coordinate for point C is given by (13, 16)

A store made 96 lb of peppermint bark for the holidays. The peppermint bark was split into 3/8 lb portions and boxes. 3/4 of the boxes were sold for $6 each before the holidays. The rest were sold at 2/3 of the pre-holiday price. How much money did the shop receive from the sales of the peppermint bark?
Answer: The shop has received $ 1724 from the sales of the peppermint bark.
Step-by-step explanation:
Given: Total quantity of peppermint bark = 96 lb
Number of [tex]\dfrac38[/tex] portions = [tex]96\div\dfrac38 =96\times\dfrac83=256[/tex]
[tex]\dfrac34[/tex] of boxes = [tex]\dfrac34\times256=[/tex] $192
These were sold for $6 each before the holidays.
i.e. Cost of [tex]\dfrac34[/tex] of boxes = [tex]192\times 6=\$1152[/tex]
2/3 of the pre-holiday price = [tex]\dfrac23\times6=\$9[/tex]
Rest of boxes = 256-192 = 64
Cost of rest of boxes = [tex]9\times64=\$ \ 576[/tex]
Total money received = $1152 + $572
= $ 1724
Hence, the shop has received $ 1724 from the sales of the peppermint bark.

A rectangular portrait has an area of 40 square feet it's perimeter is 26 feet what are the dimensions of the portrait?
Answer:
Step-by-step explanation:
Portrait is in the shape of a rectangle.
And the area of a rectangle = Length × Width
Let the length of the portrait = l
And width of the portrait = w
Area of the portrait = lw
lw = 40
l = [tex]\frac{40}{w}[/tex]
Perimeter of a rectangle = 2(Length + width)
Perimeter of the portrait = 2(l + w)
26 = 2(l + w)
l + w = 13 ----------(2)
By substituting the value of 'l' in equation (1) from equation (2)
[tex]\frac{40}{w}+w=13[/tex]
40 + w² = 13w
w² - 13w + 40 = 0
w² - 8w - 5w + 40 = 0
w(w - 8) - 5(w - 8) = 0
(w - 5)(w - 8) = 0
w = 5, 8 feet
From equation (2)
l = 8, 5 feet
Therefore, dimensions of the portrait are (5 feet by 8 feet) Or (8 feet by 5 feet).
Miranda sold movie DVD’s for $12 and television DVD’s for $9 and has collected $1167 from the sales of both. The number of movies sold is 4 less than 3 times the number of television shows. How many movie DVD’s were sold, and how many television DVD’s were sold?
Answer:
number of be television be 27 and the number of movies would be 50
Step-by-step explanation:
The computation of the number of DVD sold and the number of television sold is shown below:
Let us assume the number of television be x
So, the number of movies would be (3x - 4)
Now according to the question the following equation is made
12(3x - 4) + 9x = $1167
36x - 48 + 9x = $1,167
45x = $1,215
x = 27
So, the number of be television be 27
And, the number of movies would be
= (3x - 4)
= 3(27) - 4
= 50
What's 3(5x + 4) (I’m on a time limit
Answer:
15x + 12
Step-by-step explanation:
3(5x + 4)
15x + 12
3 · 5x = 15x
3 · 4 = 12
Combine them:
15x + 12
Answer:
3(5x + 4)
15x + 12
3 · 5x = 15x
3 · 4 = 12
15x + 12

Uhm I also need help with this
Answer:
D. PerpendicularStep-by-step explanation:
First answer A. Answer A is not even correct. Parallel are two or more lines that NEVER cross
Answer B is also not correct. Line segments are a line of specific length. These are two LINES. You can tell by the arrows on the edge of each line.
Both C and D can be correct. But the answer would be D. Here is why
Intersecting lines are two or more lines that cross. Yes these lines are crossing by perpendicular lines also cross. The difference is, intersecting lines can cross at any angle. Perpendicular lines have to cross at 90 degrees making 4 right corners.

Answer:
Option B is correct.
Step-by-step explanation:
∠A = 27
27 + 90 + 63 = 180
you can see that square right. the square is 90.

I NEED HELPP PLS!!!!!!!!!!!!!!!!!!!
Answer:
270
Step-by-step explanation:
The formula for finding the area of a triangle is base · height ÷ 2, or [tex]\frac{bh}{2}[/tex]
After plugging in the numbers given to the formula, we find that the area of the triangle is 27.
Then to account for the length, we multiply the area of the triangle by 10.
This gets us to 270.

If the slope is 3 and one ordered pair on the line is (2,9), what is the equation?
I'll give you brainliest if it's correct!
Answer:
y = 3x+3
Step-by-step explanation:
we can find the equation of the line with this formula:
y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the given point and m the slope
so we have
y-9 = 3(x-2)
y = 3x-6+9
y = 3x + 3

Estimate the median time it will take all players to finish this game.
Find the interquartile range for this sample.
Answer:
1148 ; 549.5
Step-by-step explanation:
The ordered data:
457, 548, 866, 952, 976, 1037, 1148, 1235, 1245, 1431, 1486, 1759, 1864
The median value :
1/2 * (n +1)th term
n = 13
1/2 * 14 = 7th term
Median = 1148
The interquartile range :
Q3 - Q1
Q3 = 3/4(n+1)th term
Q3 = 3/4 * 14th term
Q3 = 10.5 th term
Q3 = (10 + 11)th term
Q3 = (1431 +1486) / 2= 1458.5
Q1 = 1/4(n+1)th term
Q1 = 1/4 * 14th term
Q1 = 3.5 th term
Q1 = (3 + 4)th term
Q1 = (866+ 952) / 2= 909
IQR = 1458.5 - 909 = 549.5
Answer:
Median:1054 mins
IQR:751.5
