write the equation of a line parallel to 2x+3y=12 that passes through the point (-3,4)
Answer:
[tex]y = \frac{-2}{3}x + 2[/tex]
Step-by-step explanation:
The first step is convert the given equation in a dependent and independent equation.
[tex]2x + 3y = 12[/tex]
[tex]3y = 12 - 2x[/tex]
[tex]y = 4 - \frac{2}{3}x[/tex]
[tex]x[/tex] is the independent variable and [tex]y[/tex] the dependent variable.
Since both lines are parallel the slope of both equations are the same
[tex]y = \frac{-2}{3}x + b[/tex]
Now for find the unknow [tex]b[/tex] replace the [tex]x[/tex] and [tex]y[/tex] fo the given point.
[tex]4 = (\frac{2}{3})3 + b[/tex]
[tex]4 = 2 + b[/tex]
[tex]4 - 2 = b[/tex]
[tex]2 = b[/tex]
So the final equation is equal to
[tex]y = \frac{-2}{3}x + 2[/tex]
Please help!!!!!!!!!!!!!!!
Answer:
Y+5=2/3(x-4)
Step-by-step explanation:
since the slope is 2/3, it should be in the right side of the equal sign, its passing thru (4,-5) thus it being Y+5=2/3(x-4)

Answer:
a = 57.5
b = 57.5
Step-by-step explanation:
XY=XZ so c=d
[tex]c = d = \frac{180 - 65}{2} = 57.5[/tex]
Now draw the XH
So angle YXH = 180 — 90 — 57.5 = 32.5
a+YXH=90
a+32.5=90
so a = 57.5
We know that a + 65 + b = 180
So 57.5 + 65 + b = 180
b = 180 — 122.5
b = 57.5

From the above diagram we can conclude that ~
Angle c = Angle a (Alternate interior Angle pair)
Angle d = Angle b (Alternate interior Angle pair)
and,
Angle c = Angle dbecause their opposite sides are equal.
now, according to linear pair property ~
Angle a + Angle b + 65° = 180°replacing Angle a with Angle c and Angle d with Angle b, because they are equal to one another ~
Angle c + Angle d + 65° = 180°2 × Angle c = 180° - 65°(because Angle c = Angle d)
2 × Angle c = 115°Angle c = 115° ÷ 2 Angle c = 57.5° = Angle dSo,
Angle a = Angle c = 57.5°Angle b = Angle d = 57.5°the length of a rectangle is 5 less than 2 times its width, if the perimeter is 86ft, what is the length and width of the rectangle. Write and solve the equation
Answer:
Width: 16
Length: 27
Step-by-step explanation:
Let x be the width of the rectangle.
The length would then be 2x - 5
The perimeter is:
2x - 5 + x + 2x - 5 + x =
6x - 10 = 86
Solve.
6x = 96
x = 16
Thus,
Width: 16
Length: 27

How do I solve
-3x+y=24
-2x=+18+5y
Answer:
Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
18x−21y=24
−18x+10y=−2
Add the two equations.
−11y=22
Divide by -11 to isolate y.
y=−2
Substitute y=−2 into either of the 2 equations, I'll just use the second one.
9x+10=1
9x=−9
x=−1

You rent an apartment that costs \$800$800 per month during the first year, but the rent is set to go up 9.5% per year. What would be the rent of the apartment during the 9th year of living in the apartment? Round to the nearest tenth (if necessary).\
Pls help I'm dying here
Answer:
Monthly rent for Year 9: $1,653.5
Total cost of rent for the whole 9th year: $19,841.9
Step-by-step explanation:
Given the monthly rent of $800 for an aparment, for which it is set to increase by 9.5% annually:
Increase in the Monthly Cost of RentYear 1:The monthly rent will stay at $800 for the first year.
Year 2:For year 2, we must add the 9.5% increase in the monthly rent. In order to determine the 9.5%, simply multiply the monthly rent by 0.095 (the decimal equivalent of 9.5%), then add the product to the monthly rent in year 1 of $800.
9.5% increase for Year 2: $800 × 0.095 = $76
Monthly rent in Year 2: $800 + $76 = $876
Year 3:For year 3, we must add the 9.5% increase in the monthly rent from Year 2 ($876).
9.5% increase for Year 3: $876 × 0.095 = $83.22
Monthly rent in Year 3: $876 + $83.22 = $959.22
Year 4:For year 4, we must add the 9.5% increase in the monthly rent from Year 3 ($959.22).
9.5% increase for Year 4: $959.22 × 0.095 = $91.13
Monthly rent in Year 4: $959.22 + $91.13 = $1,050.35
Year 5:For year 4, we must add the 9.5% increase in the monthly rent from Year 4 ($1,050.35).
9.5% increase for Year 5: $1,050.35 × 0.095 = $99.78
Monthly rent in Year 5: $1,050.35 + $99.78 = $1,150.13
Year 6:9.5% increase for Year 6: $1,150.13 × 0.095 = $109.26
Monthly rent in Year 6: $1,150.13 + $109.26 = $1,259.39
Year 7:9.5% increase for Year 7: $1,259.39 × 0.095 = $119.64
Monthly rent in Year 7: $1,259.39 + $119.64 = $1,379.03
Year 8:9.5% increase for Year 8: $1,379.03 × 0.095 = $131.00
Monthly rent in Year 8: $1,379.03 + $131.00 = $1,510.04
Year 9:9.5% increase for Year 9: $1,510.04 × 0.095 = $143.45
Monthly rent in Year 9: $1,510.04 + $143.45 = $1,653.50
Yearly Cost of Rent:In order to determine the yearly cost of renting an apartment, simply multiply monthly rent by 12. In other words:
Year 1: $800 × 12 = $9600
Year 2: $876 × 12 = $10,512
Year 3: $959.22 × 12 = $11,510.64
Year 4: $1,050.35 × 12 = $12,604.15
Year 5: $1,150.13 × 12 = $13,801.55
Year 6: $1,259.39 × 12 = $15,112.69
Year 7: $1,379.03 × 12 = $16,548.40
Year 8: $1,510.04 × 12 = $18,120.50
Year 9: $1,653.50 × 12 = $19,841.94
Therefore, due to the 9.5% annual increase in rent, the monthly cost of an apartment during the 9th year is $1,653.5, or $19,841.9 (12-months' worth of rent).

x=2 y=3 3x2 is 6, then 6-3 is 3.
x=3 y=6 3x3 is 9, then 9-3 is 6
x=4 y=9 3x4 is 12, then 12-3 is 9.
x=9 y=24 3x9 is 27, then 27-3 is 24.
Answer: (2,3) , (3,6) , (4,9) , (9,24)
Step-by-step explanation: In order to get the values of y you need to plug each value of x into the function y=3x-3. to find the value of your first y you would plug in 2 to y=3x-3 which would look like 3(2)-3 and you would solve from here to get y. using PEMDAS 3 times 2 is 6 and 6 minus 3 is 3 making your y value 3 and the point (2,3). If you plug in all the other x's (3,4,9) to the function you will get the values of y for that specific x too.

3 t-shirts cost £25.95.
How much do 10 t-shirts cost?

Answer:
£86.50
Step-by-step explanation:
To find how much 10 t-shirts cost we have to find how much they cost individually.
3 T- Shirts / 25.95 = 8.65 which means that each T-Shirt Costs 8.65.
8.65 x 10 T-Shirts = £86.50
