Answer:
y - 2 = (-1/4)(x - 8)
Step-by-step explanation:
The slope of the given line is 4. The slope of any line perpendicular to the given line is the negative reciprocal of 4, which is -1/4.
Use the point-slope formula:
y - k = m(x - h), where (h, k) is the given point.
Then: y - 2 = (-1/4)(x - 8)
I am confused on this quadratic problem.
I am thinking it is (x+5)^2=81.
Here's the problem: The sum of a number and 5 is squared. The result is 81.
Answer:
(x+5)^2=81 would be correct
Step-by-step explanation:
solution (if you want it)
x² + 10x + 25 = 81
x² + 10x - 56 = 0
(x + 14)(x - 4) = 0
x = 4, x = -14
Find the area of the regular polygon.
10
5 divided by 3
Answer:
Start by setting it up with the divisor 3 on the left side and the dividend 105 on the right side like this:
3 ⟌ 1 0 5
Step 2:
The divisor (3) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:
0
3 ⟌ 1 0 5
Step 3:
Multiply the divisor by the result in the previous step (3 x 0 = 0) and write that answer below the dividend.
0
3 ⟌ 1 0 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.
0
3 ⟌ 1 0 5
- 0
1
Step 5:
Move down the 2nd digit of the dividend (0) like this:
0
3 ⟌ 1 0 5
- 0
1 0
Step 6:
The divisor (3) goes into the bottom number (10), 3 time(s). Therefore, put 3 on top:
0 3
3 ⟌ 1 0 5
- 0
1 0
Step 7:
Multiply the divisor by the result in the previous step (3 x 3 = 9) and write that answer at the bottom:
0 3
3 ⟌ 1 0 5
- 0
1 0
9
Step 8:
Subtract the result in the previous step from the number written above it. (10 - 9 = 1) and write the answer at the bottom.
0 3
3 ⟌ 1 0 5
- 0
1 0
- 9
1
Step 9:
Move down the last digit of the dividend (5) like this:
0 3
3 ⟌ 1 0 5
- 0
1 0
- 9
1 5
Step 10:
The divisor (3) goes into the bottom number (15), 5 time(s). Therefore put 5 on top:
0 3 5
3 ⟌ 1 0 5
- 0
1 0
- 9
1 5
Step 11:
Multiply the divisor by the result in the previous step (3 x 5 = 15) and write the answer at the bottom:
0 3 5
3 ⟌ 1 0 5
- 0
1 0
- 9
1 5
1 5
Step 12:
Subtract the result in the previous step from the number written above it. (15 - 15 = 0) and write the answer at the bottom.
0 3 5
3 ⟌ 1 0 5
- 0
1 0
- 9
1 5
- 1 5
0
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 105 divided by 3 calculated using Long Division is:

What is A'C, the length of AC after the dilation? What is the measure of A?
A. A'C' = 25, m A'= 37
B. A'C' = 15, m A'= 53
C. A'C' = 25, m A' = 185
D. A'C' = 1, m.A'= 37*
Answer: its A
Step-by-step explanation:
Trust me I learned the hard way
The length of AC after dilation will be 20. Then the measure of the angle ∠A' will be 37°.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
here, we have,
We have given that,
Triangle ABC is dilated by a factor of 4 to produce AA'B'C'.
The triangle ΔABC is dilated by a factor of 4 to produce the triangle ΔA'B'C'.
Then the length of AC after dilation. We have
A'C' = scale factor x AC
A'C' = 4 x 5
A'C' = 20
Then the measure of the angle ∠A' will be
There is no effect of dilation on the angle.
∠A = ∠A' = 37°
Thus, the correct option is A.

What value of x makes the equation 3(x-6)-8x= -2+5(2x+1) true
Answer:
x= −7/5
Step-by-step explanation:
Step 1: Distribute and combine like terms
3(x−6)−8x=−2+5(2x+1)
(3)(x)+(3)(−6)+−8x=−2+(5)(2x)+(5)(1)(Distribute)
3x+−18+−8x=−2+10x+5
(3x+−8x)+(−18)=(10x)+(−2+5)(Combine Like Terms)
−5x+−18=10x+3
−5x−18=10x+3
Step 2: Subtract 10x from both sides.
−5x−18−10x=10x+3−10x
−15x−18=3
Step 3: Add 18 to both sides.
−15x−18+18=3+18
−15x=21
Step 4: Divide both sides by -15.
Hope this helps! :)

How can-9 4/5
be expressed as the sum of its integer and fractional parts?
The fraction -9 4/5 can be expressed as the sum of its integer and fractional parts, which is -9 + 4/5
Expressing How can-9 4/5 as the sum of its integer and fractional partsThe integer part of a mixed number is the whole number portion, while the fractional part is the remaining fraction.
In this case, the integer part of -9 4/5 is -9, and the fractional part is 4/5.
To express the mixed number as the sum of its integer and fractional parts, we simply add the integer and the fraction:
So, we have
-9 + 4/5
When evaluated, we get
-9 + 4/5 = -45/5 + 4/5 = -41/5
Therefore, -9 4/5 can be expressed as the sum of its integer and fractional parts, which is -9 + 4/5 = -41/5.

The Wilsons have triplets and another child who is 14 years old. The sum of the ages of their children is 38. How old are the triplets? Please give me the equation!! Correct answer will get brainliest
Answer:
Each age of the triplets should be 8 years old.
Step-by-step explanation:
38-14=24
24 divided by 3 = 8
Answer:
Triplets are 8 not sure on the equation but I think its y = 8x + 38.
Step-by-step explanation:
I'm assuming that all their ages together equal 38 therefore I would take,
38 - 14 = 24; this means that the triplets ages added together equal 24. Since triplets means 3 I will take,
24 dived 3 = 8.
I check my work by doing 14 + 8 + 8 + 8 = 38.
you asked for an equation I'm sure what you mean but I can try; I'm putting it into slope intercept form.
y = 8x + 38
There are 12 steps in the staircase. Plz don't do it for points!!! How do you get the answer 150? i am really struggling will mark brainliest.
The distance from point A to B is 1 foot.
Given,
There are 12 steps in the staircase.
We need to find the distance of the steps.
The distance is given by AB.
Feet is the plural form of the foot.
What is a Pythagorean theorem?It states that in a right-angle triangle the hypotenuse is equal to the squares of the other two sides.
If the hypotenuse is H and the other two sides are A and B.
H² = A² + B²
We have a figure,
Where it is in a right-angled triangle.
Two sides are given: 7.5 inches and 10 inches.
And hypotenuse = AB.
Applying the Pythagorean theorem.
7.5² + 10² = AB²
AB² = 56.25 + 100
AB² = 156.25
AB = [tex]\sqrt{156.25}[/tex]
AB = 12.5 inches
Now,
AB = 12.5 inches.
We need to convert it into feet.
12 inches =1 foot
Multiplying 12.5/12 on both sides.
12.5/12 x 12 inches = 12.5/12 x 1 feet
12.5 inches = 1.0416 feet
Rounding to the nearest tenth we get,
12.5 inches = 1 feet
AB = 1 feet
Thus the distance of the staircase from point A to B is 1 foot.
