What is the value of x in the equation 2x – 3 = 9- 4x?
0 -6
O-3
O 1
o 2
Answer:
x = 2
Step-by-step explanation:
2x - 3 = 9 - 4x
6x - 3 = 9 (added 4x to both sides)
6x = 12 (added 3 to both sides)
x = 2 (divided 12 by 6)
hope this helps :)

Answer:
4y-12
Step-by-step explanation:
Use the given information to find the measure.
Answer:
From the image, we can see that ∠AOC = ∠AOB + ∠BOC
We are given the following values:
∠AOC = 104
∠AOB = 7x + 30
∠BOC = 9x + 42
Plugging these values in the equation above:
∠AOC = ∠AOB + ∠BOC
104 = 7x + 30 + 9x + 42
104 = 16x + 72
16x = 32
x = 2
Now that we have the value of x, we can easily find the value of ∠BOC
We are given that:
∠BOC = 9x + 42
∠BOC = 9(2) + 42 (since x = 2)
∠BOC = 18 + 42
∠BOC = 60°
Therefore, ∠BOC is 60 degrees
How do you do this question?
Answer:
18π
Step-by-step explanation:
Arc length for a parametric equation is:
s = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt
dx/dt = -9 sin(9t)
dy/dt = 9 cos(9t)
s = ∫₀²ᵖⁱ √((-9 sin(9t))² + (9 cos(9t))²) dt
s = ∫₀²ᵖⁱ √(81 sin²(9t) + 81 cos²(9t)) dt
s = ∫₀²ᵖⁱ 9 dt
s = 9t |₀²ᵖⁱ
s = 18π
You can check your answer with geometry. The curve is a circle centered at the origin with radius 1. From 0 to 2π, the particle makes 9 revolutions, or travels 18π radians. So the arc length is 1 × 18π = 18π.

Jazzy Signs pays $5 for materials to build their wooden signs. They sell each sign for $36.
Approximately what percentage of increase does Jazzy Signs sell their wooden signs for?
Answer:
720 %
Step-by-step explanation:
Hi there !
$ 5 ............. 100%
$ 36 .................x%
x = 36×100/5
= 3600/5
= 720 %
Good luck !
Answer:
720%Step-by-step explanation:
percentage of a sale increase from $5 to $36
just divide the sale price from $36 to $5
$ 36
$ 5
= 7.2 (100%)
= 720 % ( a profit of $36 - $5 = $31 )
proof:
$5 x (7.2) = $36

Answer:
∠FJH ≅ ∠BJA
Step-by-step explanation:
From the image we can see that the only congruent relation ∠FJH has is with ∠BJA which is due to these angles being vertically opposite
So, ∠FJH and ∠BJA are vertically opposite and hence, congruent. We can say that ∠FJH ≅ ∠BJA

The measure of angle 1 is (3x + 10)° and the measure of angle 4 is (4x – 15)°.
Vertical and parallel lines c, d, and e are cut by diagonal transversal a. On line c where it intersects with line a, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 2, 4, 3, 1. On line b where it intersects with line a, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 6, 8, 7, 5.

Which polygon has an interior angle sum of 1080°?
A polygon has 8 sides.
A polygon has 10 sides.
A polygon has 9 sides.
A polygon has 7 sides.
Answer:
option B : polygon with 8 sides.
Answer:
It is the first option 8 sides.
Step-by-step explanation:
we can set an equation up for this question: 1080=180(n-2)
divide:
1080/180=n-2
= 6=n-2
= n=8

What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The graph of the linear function shown in the image.
Now,
Two points on the graph are (3, 350) and (2, 250).
Hence, Rate of change = (250 - 350) / (2 - 3)
= -100/-1
= 100
Thus, The rate of change with respect to the number of deposit will be 100.

If the length of AC equals 18, what is the length of the midsection DE
Answer:
The length of the midsegment is 9 ⇒ (B)
Step-by-step explanation:
In a triangle,
The midsegment is the segment which joining the midpoints of two opposite sides of itThe length of the midsegment is half the length of the third side in the triangle which opposite to itLet us use this rule to solve our question
In Δ AC
∵ DE is the midsegment of it
∵ DE is opposite to the side AC
∴ The length of DE = 1/2 the length of AC
∵ The length of AC = 18
∴ The length of DE = 1/2 × 18
∴ The length of DE = 9
∴ The length of the midsegment is 9
The correct answer is B
If e^5x=k, where k is any positive number then what is the value of x
Answer:
If [tex]k > 0[/tex], then [tex]x[/tex] must be greater than 0.
Step-by-step explanation:
If [tex]k > 0[/tex], then we state that [tex]e^{5\cdot x} > 0[/tex] and [tex]e^{5\cdot x}[/tex] is a trascendental function with a lower bound so that [tex]e^{5\cdot x}> 1[/tex]. Then, the minimum value of [tex]k[/tex] is 1 and we proceed to solve the latter equation to find the value of [tex]x[/tex]:
[tex]e^{5\cdot x}> 1[/tex]
[tex]\ln e^{5\cdot x} > \ln 1[/tex]
[tex]5\cdot x > 0[/tex]
[tex]x > 0[/tex]
Therefore, [tex]x[/tex] must be greater than 0.
what is the answers for this
Answer:
6. The triangle is acute
m<P = 60
m<Q = 84
m<R = 36
----------------
7. Claim: the three angles added together equal 180 degrees
m<J = 116 degrees
m<K = 33 degrees
m<L = 38 degrees
Step-by-step explanation:
m<P = 4a + 12 = 4(12) + 12 = 60
m<Q = 7a = 7(12) = 84
m<R = 3a = 36
(4a + 12) + 7a + 3a = 180 degrees
14a + 12 = 180
14a = 168
a = 12
----------------
m<J = 4x + 12 = 4(26) + 12 = 116
m<K = x + 7 = 26 + 7 = 33
m<L = 2x - 14 = 2(26) - 14 = 38
(4x + 12) + (x + 7) + (2x - 14) = 180 degrees
7x - 2 = 180
7x = 182
x = 26
