Answer:
2x^2 + 2y^2
Step-by-step explanation:
Combine like terms.
(x^2 + 2xy + y^2) + (x^2 - 2xy + y^2) =
= x^2 + 2xy + y^2 + x^2 - 2xy + y^2
= x^2 + x^2 + 2xy - 2xy + y^2 + y^2
= 2x^2 + 2y^2
Answer:
2x^2 + 2y^2

Step-by-step explanation:
A plot of land is valued at $18,000.Land tax is charged at the rate of 0.70 per $100. What is the total amount of tax paid for the land?
Answer:
The total amount of tax paid for the land was $126
Step-by-step explanation:
Proportions
The land tax charged is 0.7 per each $100 of the land value. For easy calculations, we find the ratio or proportion to be applied to the value of the land as:
0.7 / 100 =0.007
This factor can be used to obtain the tax charged for a given value of the land.
The plot of land of the question is valued at $18,000.
The tax charged is, then:
0.007*18,000 = 126
The total amount of tax paid for the land was $126

Answer:
1/49 is the answer
Step-by-step explanation:
Which relation represents a function?
StartSet (0, 0), (2, 3), (2, 5), (6, 6) EndSet
StartSet (3, 5), (8, 4), (10, 11), (10, 6) EndSet
StartSet (negative 2, 2), (0, 2), (7, 2), (11, 2) EndSet
StartSet (13, 2), (13, 3), (13, 4), (13, 5) EndSet
A
B
C
D
Here we don't have any repeated x values.
In choice A, x = 2 repeats. In other words, x = 2 leads to multiple y outputs. So this is not a function. Choices B and D are similar stories. A function is only possible if every x leads to exactly one y value only. The graph must pass the vertical line test.
Side note: the y values can repeat, but the function won't be one-to-one.
3/4 divided by 1/2 what do you guys think?
Answer:
It is 1 1/2
Step-by-step explanation:
When you divide a fraction, it multiplies
So instead of dividing by 1/2, multiply by 2
Answer:
2 / 3
Step-by-step explanation:
( 3 / 4 ) / ( 1 / 2 )
= ( 3 x 2 ) / ( 4 / 1 )
= 6 / 4
= 2 / 3
Find the coordinates of the midpoint of segment AB with endpoints A(-2,3) and B(5,-2)
Answer:
The coordinates of the midpoints are (3/2, 1/2)
Step-by-step explanation:
To find the midpoint you must se the midpoint formula. Using this formula, when you plug in the points given and you simplify, you find out the midpoint is the coordinates (3/2, 1/2). I hope this helps!
solution for 3/4x - 12 = -18?
Answer:
x = -8
Step-by-step explanation:
Add 12 on both sides
You get 3/4x = -6
Multiply 4/3 on both sides
You get x = -24/3
Simplify and you get -8.
Answer:
x=-8
Step-by-step explanation:
The reason why x is -8 is because
The first step is to isolate the x
To isolate the x you got to add 12 to both sides
[tex]\frac{3}{4}[/tex]x-12+12=-18+12
the -12 gets canceled out by the positive twelve so all thats left now is
[tex]\frac{3}{4}[/tex]x=-18+12,-18+12 is -6 so its [tex]\frac{3}{4}[/tex]x=-6
The second step is to divide
now you have to divide by [tex]\frac{3}{4}[/tex] on both sides
[tex]\frac{\frac{3}{4} x}{\frac{3}4} } =\frac{-6}{\frac{3}{4} }[/tex]
which [tex]\frac{3}{4}[/tex] is taken out on the left side because its divided by itself so all thats left is a one,while on the right side -6 divided by three-fourths is -8
Aline has an x-intercept of 3 and a y-intercept of -6.
The slope-intercept form of its equation is
(0,6) & (3,0)
m = (y2-y1)/(x2-x1)
m = (0-6)/(3-0)
m = -6/3
m = -2
Substitute the values in y = mx + c
0 = -2(6) + c
c = 12
Thus, the equation is y = -2x + 12
Answer:
y=2x-6
Step-by-step explanation:
You can plug this into the slope formula, x-intercept of 3 would be (3,0)
and y intercept of -6 would be (0,-6).
Find the slope using the slope formula. The slope is 2
We are given a y-intercept of -6
therefore, the answer is y=2x-6

you notice a hot air balloon is sending the elevation H in feet of the balloon is modeled by the function h x equals 6X + 90 where X is the time in second since you first noticed the hot air balloon
Answer: you should ask your teacher for help...
Step-by-step explanation:
Answer:
1. 0
2. 0
3. 6
4. 6
5. 90
6. 90
Step-by-step explanation:
x is greater than or equal to 0, and h is greater than or equal to 0, because since it is ascending, it is constantly getting more time, and getting higher up. The slope is 6, so the change of the feet for the hot air balloon is 6 feet per second, and the h- intercept is 90, so the first time you noticed it, is was at 90 feet, so put your points at (0,90) and at (30, 180)

Five less than three times a number is 1. Find the number
Answer:
n = 2
Step-by-step explanation:
Step 1: Write equation
"Five less" = subtract 5
"three times a number" = 3 × n, or 3n
"is 1" means = 1
3n - 5 = 1
Step 2: Solve for n
Add 5 to both sides: 3n = 6Divide both sides by 3: n = 2X + (-9) = 32
What is the answer
Answer:
the answer to x+(-9)=32 is x=41
a certain map shows two roads. road a is 1 1/4 miles long but is 1 1/2 inches long on the map. what the unit rate for inches per miles on this map? if road b is 10 miles long, how long is road b on the map?
Answer:
30 inches
Step-by-step explanation:
Length of road A = 1¼ miles
Length of road A on map = 1½ inches
Unit rate for inches per miles on the map = 1½ inches ÷ 1¼ miles = ³/2 ÷ ⁵/4 = ³/2 × ⅘ = ⁶/5 inches per mile
Length big Road B on map:
Road B actual length = 10 miles
Thus, using the unit rate of ⁶/5 inches to 1 mile, length of road B on map would be calculated as shown below:
⁶/5 × 10 = 6*5 = 30 inches
Road B is 30 inches long on the map.
