margo is repaying a loan from her parents. she has already paid $315 and still owes them $1245. write an equation to find the original amount a of the loan
Answer:
n-315=1245
Step-by-step explanation:
n stands for the original amount of the loan. Margo has paid $315, so the original number minus what Margo has paid, and the equality is the amount that Margo still owes.

Answer: 65 degrees
Explanation:
The adjacent angle directly above angle 8 is congruent to the 115 degree angle (due to the corresponding angles theorem). This only works because p || q and q || r, so by the transitive property of parallel lines, we know that p || r.
Since the 115 degree angle and angle 8 pair up to form a straight line, we know that the two angles must add to 180 degrees
115+(angle 8) = 180
angle 8 = 180 - 115
angle 8 = 65 degrees
Answer:
[tex]m[/tex]∠8 = 65°
Step-by-step explanation:
The other side (angle) of 115 is [tex]n[/tex] and [tex]n =[/tex] ∠8
To find [tex]n[/tex] you need to subtract 180 - 115 giving you 65, and since n is angle 8, angle 8 is also 65 since the angles have a state of congruence...

evan is running a marathon. He wants to caculate his average speed between two checkppints. He reaches the 3- mile checkpoint after 0.75 hour and the 18- mile checkpoint after 2 hours what is evans average speed, in miles per hour between the two checkpoints
Answer:
12
Step-by-step explanation:
18/2-3/.75=15/1.25
The average speed of Even between two checkpoints is 9 miles per hour.
What is an average speed?The distance covered by the particle or the body in an hour is called the average speed. It is a scalar quantity. It is the ratio of the total distance to the total time.
We know that the average speed formula is given as,
Average speed = Total distance / Total time
Running a marathon is Evan. Between two checkpoints, he wants to compute his average speed. He takes 0.75 hours to go to the 3-mile checkpoint and 2 hours to get to the 18-mile milestone.
The average speed is given as,
Average speed = 18 / 2
Average speed = 9 miles per hour
The average speed of Even between two checkpoints is 9 miles per hour.

Higher Order Thinking A farmer grows
128 red tomato
plants and 102 yellow tomato plants. Each plant produces
about 32 tomatoes. The farmer plans to
sell each tomato
for a $2. Explain how to find a reasonable estimate for the
total amount of money the farmer will earn if she sells all
of the tomatoes.
Answer: 14720 dollars, or $14720
Step-by-step explanation:
128 red tomato plants plus 102 yellow tomato plants = 230 tomato plants in total.
230 plants with 32 tomatoes each = 7360 tomatoes in all
7360 x 2 dollars = 14720 dollars
e^3x.cos4x.sin2x hii please solv this you have to differentiate
Answer:
[tex]y = e^{3x}.cos4x.sin2x[/tex]
[tex]=> y' =- 3e^{3x}.4sin4x.2cos2x=-24.e^{3x}.sin4x.cos2x[/tex]
[tex]dy=y'.dx => dy = -24e^{3x}.sin4x.cos2x.dx[/tex]
Step-by-step explanation:
The function [tex]e^3^x[/tex].cos4x.sin2x on differentiating gives the solution as 2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x.
What is Product rule in Differentiation?Product rule in differentiation states that, for two functions f(x) and g(x),
[tex]\frac{d}{dx}[/tex] [f(x).g(x)] = f(x) . [tex]\frac{d}{dx}[/tex][g(x)] + g(x) . [tex]\frac{d}{dx}[/tex][f(x)]
The question is to differentiate y = [tex]e^3^x[/tex].cos4x.sin2x
We have three functions here.
Let u = [tex]e^3^x[/tex] and v = cos4x.sin2x
[tex]\frac{d}{dx}[/tex] [u . v] = u [tex]\frac{d}{dx}[/tex][v] + v [tex]\frac{d}{dx}[/tex][u]
= [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + cos4x.sin2x [tex]\frac{d}{dx}[/tex] [[tex]e^3^x[/tex] ]
= [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + cos4x.sin2x (3[tex]e^3^x[/tex])
[tex]\frac{d}{dx}[/tex] [u . v] = [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + 3[tex]e^3^x[/tex]cos4x.sin2x
Let the above equation be equation E.
Again apply the product rule for [tex]\frac{d}{dx}[/tex] [cos4x.sin2x].
Let u' = cos4x and v' = sin2x
[tex]\frac{d}{dx}[/tex] [u'. v'] = u' [tex]\frac{d}{dx}[/tex][v'] + v' [tex]\frac{d}{dx}[/tex][u']
= cos4x [tex]\frac{d}{dx}[/tex][sin2x] + sin2x [tex]\frac{d}{dx}[/tex][cos4x]
= cos4x [2cos2x] + sin2x [-4sin4x]
= 2cos2x.cos4x - 4sin2x.sin4x
Substituting this is equation E, we get,
[tex]\frac{d}{dx}[/tex] [u . v] = [tex]e^3^x[/tex] [2cos2x.cos4x - 4sin2x.sin4x] + 3[tex]e^3^x[/tex]cos4x.sin2x
= 2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x
Hence the function [tex]e^3^x[/tex].cos4x.sin2x on differentiating gives 2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x.

The balanced scale represents the equation: 3x + 1 - 2x + 4
If two x blocks are subtracted from the right side and one numbered block is subtracted from the left side. What process will
balance the scale?
A)
subtract two x blocks from the left side and subtract one numbered block
from the left side
B)
subtract two x block from the left side and subtract one numbered block
from the right side
C)
subtract two x blocks from the right side and subtract one numbered block
from the left side
D)
subtract two x block from the right side and subtract one numbered block
from the right side
Answer:
B
Step-by-step explanation:
the equal is correctly
3x + 1 = 2x + 4
what was done now :
2 x-blocks (2x) subtracted from the right side, and 1 numbered block subtracted from the left side.
to reestablish balance and equality of both sides, we need to do more the exact same things - just in the other sides.
2 x-blocks subtracted from the LEFT side, and 1 numbered block subtracted from the RIGHT side.
and that is answer B.

I am not sure who made the dots on the charts, but they are wrong.
y = 1/2 x + 3
domain means all valid values for x.
range means all valid values for y (the functional results).
x = 0
y = 1/2 × 0 + 3 = 3
x = 1
y = 1/2 × 1 + 3 = 3.5
x = 2
y = 1/2 × 2 + 3 = 4
x = 3
y = 1/2 × 3 + 3 = 4.5
x = 4
y = 1/2 × 4 + 3 = 5
so, the range is 3, 3.5, 4, 4.5, 5
y = x - 6
x = 10
y = 10 - 6 = 4
x = 12
y = 12 - 6 = 6
x = 14
y = 14 - 6 = 8
x = 16
y = 16 - 6 = 10
x = 18
y = 18 - 6 = 12
so, the range is 4, 6, 8, 10, 12
3y=9-12x I need the slope for this equation and the steps
Answer:
slope = -4
Step-by-step explanation:
3y = 9 - 12x
Rearrange the right-hand side:
3y = - 12x + 9
Next, Divide both sides by 3 to isolate y:
[tex]\frac{3y}{3} = \frac{-12x + 9}{3}[/tex]
y = -4x +3 this is the slope-intercept form where the slope, m = -4, and the y-intercept, b = 3.
Therefore, the slope = -4.
