SHOW YOUR WORK for full points. Write your answer as an (x,y) point.
x=4y-1
x+2y=11
Answer:
x = 7, y = 2
Step-by-step explanation:
x= 4y -1
since x is by itself 4y-1 will substitute for x in the other equation x+2y=11
it will become 4y-1+2y=11
+1 +1
add one to both sides since is doesn't have a variable.
it will become 4y+2y= 12 now add 4y+2y
becomes 6y=12
_ _
6 6
divide by 6 on each side and you get y=2.
now x=4(2)-1 you will substitute y into the first equation.
x=8-1 subtract 8 from 1 to get 7.
x=7
y=2

Identifying the slope, y-intercept and x- intercept of each
Answer:
slope= -3
y-intercept= 6
Step-by-step explanation:
1. Approach
To solve this problem, one needs the slope and the y-intercept. First, one will solve for the slope, using the given points, then input it into the equation of a line in slope-intercept form. The one can solve for the y-intercept.
2.Solve for the slope
The formula to find the slope of a line is;
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where (m) is the variable used to represent the slope.
Use the first two given points, and solve;
(1, 3), (2, 0)
Substitute in,
[tex]\frac{(0)-(3)}{(2)-(1)}[/tex]
Simplify;
[tex]\frac{-3}{1}\\\\=-3[/tex]
3. Put equation into slope-intercept form
The equation of a line in slope-intercept form is;
[tex]y = mx + b[/tex]
Where (m) is the slope, and (b) is the y-intercept.
Since one solved for the slope, substitute that in, then substitute in another point, and solve for the parameter (b).
[tex]y=-3x+b[/tex]
Substitute in point (3, -3)
[tex]-3=-3(3)+b\\-3 = -9 + b\\6 = b[/tex]

Answer:

Step-by-step explanation:
Mark would need a total of 824 feet of fencing to surround all four rectangular gardens.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
To calculate the total length of fencing Mark needs to surround all four gardens, we first need to determine the perimeter of one rectangular garden.
The perimeter of a rectangle is given by the formula:
P = 2l + 2w,
where P is the perimeter, l is the length, and w is the width.
For one rectangular garden with a length of 60 feet and a width of 43 feet, the perimeter would be:
P = 2(60) + 2(43) = 120 + 86 = 206 feet.
Therefore, to surround all four gardens, Mark would need a total of:
4 x 206 feet = 824 feet of fencing.
Thus,
Mark would need a total of 824 feet of fencing to surround all four rectangular gardens.

Tell whether each system of equations has no solution or ,infinitely many solutions.
Answer:
See below.
Step-by-step explanation:
x + 2 = x + 2 ⇒ Infinitely Many Solutions
3x + 1 = 3x - 10 ⇒ 1 ≠ -10 ⇒ No solutions
x + 4 = 2x + 4 ⇒ 4 = x + 4 ⇒ 0 = x ⇒ One solution
what is 982 rounded to the nearest hundred
When the 982 rounded to the nearest hundred so it comes 1000.
The following information should be relevant:
At the time of rounding off the numbers, we have to look at whether the tens digit is 5 or more or it should be less than 4 or 4.If it is 5 or more so the same should be rounded up.And, if it is 4 or less so the same should be rounded down.Therefore we can conclude that When the 982 rounded to the nearest hundred so it comes 1000.

I'm not sure if this is exactly right because the wording of the problem is confusing.
Answer:
a) Number of square feet of wallpaper for bedroom = 12x^2 - 21
b) Number of square feet of wallpaper for living room = 14x^2 - 42
c) Total amount of wallpaper needed = 26x^2 - 63
d) 107 more sq ft of wallpaper will be needed for the living room than bedroom.
Step-by-step explanation:
a) First find the area of each wall.
Length: 3x, Width: 3x, Height: x
(3x × x) + (3x × x) + (3x × x) + (3x × x) = 3x^2 + 3x^2 + 3x^2 + 3x^2 = 12x^2
12x^2 represents the amount of wallpaper needed, including the door. Find the area of the door and subtract it from this value.
3 × 7 = 21
12x^2 - 21 = Total sq ft of wallpaper needed for bedroom
b) First find the area of each wall.
Length: 4x, Width: 3x, Height: x
(4x × x) + (4x × x) + (3x × x) + (3x × x) = 4x^2 + 4x^2 + 3x^2 + 3x^2 = 14x^2
14x^2 represents the amount of wallpaper needed, including the door. Find the area of both doors and subtract it from this value.
3 × 7 = 21 × 2 = 42
42x^2 - 42 = Total sq ft of wallpaper needed for living room
c) Add the two expressions to find the total amount of wallpaper needed.
(12x^2 - 21) + (42x^2 - 42) = 26x^2 - 63
26x^2 - 63 = Total sq ft of wallpaper needed for both rooms
d) Plug x = 8 into the equations found in part a and b.
12(8)^2 - 21 = 747
14(8)^2 - 42 = 854
Subtract these answers to find the difference in amount.
854 - 747 = 107
The living room needs 107 sq ft more of wallpaper than the bedroom
