A dog trainer is trying to find a triangular area behind his house that encloses 1800 square feet for his dog to run. He has the first two fence posts at (6, 0) and at (0, 25). The final fence post is on the property line at x = 30. Find the point where the trainer can place the final fence post.
Answer:
[tex]C = (30,500)[/tex]
Step-by-step explanation:
Given
[tex]Area = 1800ft^2[/tex]
[tex]A = (6,0)[/tex]
[tex]B = (0,25)[/tex]
[tex]C(x,y) = (30,y)[/tex]
Required
Determine the coordinates of C
The area of triangle is calculated as thus:
[tex]Area = \frac{|A_x(B_y - C_y) + B_x(C_y - A_y) + C_x(A_y - B_y)|}{2}[/tex]
This gives:
[tex]1800= \frac{|6(25 - y) + 0(y - 0) + 30(0 - 25)|}{2}[/tex]
[tex]1800= \frac{|6(25 - y) + 30(0- 25)|}{2}[/tex]
[tex]1800= \frac{|6(25 - y) + 30(-25)|}{2}[/tex]
[tex]1800= \frac{|150 - 6y -750 |}{2}[/tex]
[tex]1800= \frac{|150 -750- 6y |}{2}[/tex]
[tex]1800= \frac{|-600- 6y |}{2}[/tex]
Multiply through by 2
[tex]2 * 1800= |-600- 6y|[/tex]
[tex]3600= |-600- 6y|[/tex]
[tex]3600= |-(600+ 6y)|[/tex]
[tex]3600= 600+ 6y[/tex]
Solve for 6y
[tex]6y = 3600 - 600[/tex]
[tex]6y = 3000[/tex]
Solve for y
[tex]y = 3000/6[/tex]
[tex]y = 500[/tex]
Hence:
The point is:
[tex]C = (30,500)[/tex]

Solve for nn by simplifying both sides of the equation, then isolating the variable.
n=4, −2
Answer:
We know that a modulus gives us the absolute value of a number
Hence, this modulus will give a positive value, regardless of the actual value in the modulus
| -1 + n | = 3
(-1 + n) or (1 - n) = 3 -------------------This tells us that either one of the values will give us the same answer
-1 + n = 3 or 1 - n = 3
n = 4 or n = -2

Peter is saving money to buy an MP3 Player. After one month, he has $50. After two months he has $85. After three months, he has $120. He plans to keep saving at the same rate. How long will it take Peter to save enough money to buy an MP3 Player that costs $295?
Answer:
9 months
Step-by-step explanation:
peter is saving 35 dollars per month.
295=35x
295/35=8.42 which is less than 295
9 is an approximate answer
35*9 equals 315, which is enough to pay 295 and have 20 dollars left over
Find the midpoint of the segment with the following endpoints.
(-6, 4) and (-1,-6)
Answer:
Hello
Midpoints of (-6,4),(-1,-6)
P(a,b)=(x1+x2/2),(y1+y2/2)
=(-6+-1/2),(4+-6/2)
=(-7/2),(-2/2)
=(-7/2),(-1)
Midpoints of the segment with endpoints (-6, 4) and (-1,-6) are (-7/2),(-1)

Solve and Simplify -3-7/8
Answer:-1.25
Step-by-step explanation: First you add -3 and -7 it is -10/8 then you devide -10/8 and it is -1.25
In the figure, m∠1=(2x+40)° and m∠8=(12x−20)° . PLEASE IM BEGGING FOR HELP
For what value of x is m∥n ?
Enter your answer in the box.
x =
Answer: x = 6
Step-by-step explanation:
Angles 1 and 8 are alternate exterior angles, so they are equal.
So you can create an equation to solve for x
12x−20 = 2x+40 Subtract 2x from both sides. Add 20 to both sides
10x = 60
x = 6
If you need the m∠1, Substitute 6 for x. (2x+40)° 2(6) +40= 12+40 m∠1= 52°
m∠8=(12x−20)° 12(6) - 20 = 72-20 m∠8 = 52°
Answer:
x=6

Find the error and and the correct answer
Answer:
Error: Multiplied both sides by 3/4 instead of 4/3.
Solution: x = 16
Step-by-step explanation:
The error is that you multiplied both sides by [tex]\frac{3}{4}[/tex] instead of dividing both sides by [tex]\frac{3}{4}[/tex].
This is an error because:
[tex]\frac{3}{4} *\frac{3}{4} x\neq x[/tex]
Actually:
[tex]\frac{3}{4} *\frac{3}{4} x=\frac{9}{16} x[/tex]
What you want to do instead is divide both sides by [tex]\frac{3}{4}[/tex]. Remember, dividing both sides by [tex]\frac{3}{4}[/tex] would be the same as multiplying both sides by [tex]\frac{4}{3}[/tex].
Now, lets find the correct answer:
[tex]\frac{3}{4}x=12[/tex]
Multiply both sides by 4/3.
x = 16
So the correct answer would be x = 16.
I hope this helps. Happy studying.
what is the steps to this problem.
2(3b-2)=2(2b+12)
Answer:
14
Step-by-step explanation:
Step 1:
2 ( 3b - 2 ) = 2 ( 2b + 12 ) Equation
Step 2:
6b - 4 = 4b + 24 Multiply
Step 3:
6b = 4b + 28 Add 4 on both sides
Step 4:
2b = 28 Subtract 4b on both sides
Step 5:
b = 28 ÷ 2 Divide
Answer:

solve for x 3x+10 3x -28 will mark brainest answers are 1. 33 2. 34 3. 35 4. 36 ty so much 1 left godbless
Answer:
1. x = 33Step-by-step explanation:
3x+10 + 3x -28 = 180
3x + 3x = 180 + 28 - 10
6x = 198
x = 198/6
x = 33
Answer:
33
Step-by-step explanation:
By the same side interior angle theorem, we can find that 3x + 10 and 3x - 28 are supplementary. Knowing this, we can make the equation:
(3x + 10) + (3x - 28) = 180
Now we can solve for x. Combine like terms.
6x - 18 = 180
Add 18 from both sides.
6x = 198
Divide both sides by 6.
x = 33
So the value of x would be 33.

What is f(5)?
Hello!
f(x) = 3x + 2
Since you are provided with f(5), we will replace every "x" in the equation with the number 5.
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17
