What is the value of x in the equation 8+4 = 2(x-1)2
O 5
11
o
2
끌
o
13
2
O 7
Step-by-step explanation:
→ 8 + 4 = 2(x -1)
→ 12 = 2x - 2
→ 2x - 2 = 12
→ 2x = 12 + 2 = 14
→ x = 14/2 = 7
→ x = 7
hence, option D (7) is correct.
Hope this answer helps you dear ! take care
what is an equation of the line that passes through points (-7,-5) and (-7,-2)?
Answer:
x=-7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-2-(-5))/(-7-(-7))
m=(-2+5)/(-7+7)
m=3/(0)
undefined
x=-7.

After one of your limbs is amputated, you may feel as if the limb is still there. This is called phantom sensation. You may feel: Pain in your limb even though it is physically not there.
Answer:
The nerve in your leg.
Explanation:
It's not your leg that will hurt but the nerve in your leg that'll hurt. So wherever the leg is cut, the nerves must be cut as well, but another thing is when one of your limbs is amputated, you may feel like the limb is still there. That's called phantom sensation. You might feel pain in your "limb" even though it's not physically there.

The sum of the angle measures of a triangle is 180°. Find the value of x. Then find the angle measures of the triangle.
Answer:
x = 4343°, 51°, 86°Step-by-step explanation:
The sum of the angles is ...
x° + (x +8)° + 2x° = 180°
4x +8 = 180 . . . . . . . . . . . collect terms, divide by °
x +2 = 45 . . . . . . . . . . divide by 4
x = 43 . . . . . . . . . . subtract 2
x +8 = 51
2x = 86
The angles are 43°, 51°, 86°.

3/4 x-3 = -18
NO LINKS WHATSOEVER
Answer:
Add 3 to both sides.
Step-by-step explanation:
Add 3 to both sides.
This is how you figure it out. Imagine you have a value you want to use for x on the left side, such as 5.
In other words, evaluate 3/4 x - 3 for x = 5
The left side turns into 3/4 × 5 - 3.
What order of operations would you use now on the left side.
1) Multiply 3/4 by 5
2) Subtract -3
To solve an equation, you do the opposite operations in the opposite order.
Since to evaluate the left side with a number for x, you end by subtracting 3, to solve the equation you start by adding 3. Then you divide by 3/4.
Answer: add 3 to both sides

The sum of three terms in AP is 15. If the first two terms are each decreased by 1 and the last is increased by 1 then the resulting terms are in GP. find the numbers.
Answer:
3, 5, ,7 or 9, 5, 1
Step-by-step explanation:
Let the three terms in AP be a - d, a & a + d
where a = First term and d = Common difference.
Condition 1: sum of three terms in AP is 15.
a - d + a + a + d = 15
3a = 15
a = 15/3
a = 5
Condition 2: When first two terms are each decreased by 1 and the last is increased by 1 then new terms so obtained will be as follows:
a - d - 1, a - 1, a + d + 1
These terms are in G.P.
[tex] {(a - 1)}^{2} = (a - d - 1)(a + d + 1) \\ \\ {(5 - 1)}^{2} = (5 - d - 1)(5 + d + 1) \\ \\ {(4)}^{2} = (4 - d)(6 + d) \\ \\ 16 = 24 + 4d - 6d - {d}^{2} \\ \\ 0 = 8 - 2d - {d}^{2} \\ \\ {d}^{2} + 2d - 8 = 0 \\ \\ {d}^{2} + 4d - 2d - 8 = 0 \\ \\ d(d + 4) - 2(d + 4) = 0 \\ \\ (d + 4)(d - 2) = 0 \\ \\ d + 4 = 0 \: \: or \: \: d - 2 = 0 \\ \\ d = - 4 \: \: or \: \: d = 2 \\ \\ when \: d = - 4 \\ \\ a - d = 5 - ( - 4) = 9 \\ a = 5 \\ a + d = 5 - 4 = 1 \\ \\ when \: d = 2 \\ a - d = 5 - 2 = 3 \\ a = 5 \\ a + d = 5 + 2 = 7 \\ \\ thus \: three \: terms \: in \: AP \: are: \\9, \: 5, \: 1 \: \: or \: \: 3, \: 5, \: 7[/tex]

please help !! question is shown below in the picture
Answer:
C
Step-by-step explanation:
Given x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 20 , y = 10 then
10 = 20k ( divide both sides by 20 )
[tex]\frac{10}{20}[/tex] = [tex]\frac{1}{2}[/tex] = k
y = [tex]\frac{1}{2}[/tex] x ← equation of variation → C

Answer:1 or 2/2
Step-by-step explanation:
-2 to 0 is adding 2 and 0 to 3 is also adding two so for x it will be two
For Y it is from 4 to 6 so it is also adding 2 and from 6 to 8 your also adding 2
So y will be 2
And 2/2 is 1
