Please help! Geometry practice was lines cut by a transversal. What is the value of X?
Answer:
x = 70
Step-by-step explanation:
1. First, we need to know that the angle with 45 degrees and the angle with (2x-5) degrees are same-side interior angles, meaning they add up to 180 degrees. The equation of this can be written as so: [tex]2x-5+45= 180[/tex]
2. (Solving)
Step 1: Combine like terms.
[tex](2x) +(-5+45) = 180[/tex] [tex]2x + 40 = 180[/tex]Step 2: Subtract 40 from both sides.
[tex]2x + 40 - 40 = 180 - 40[/tex] [tex]2x = 140[/tex]Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{140}{2}[/tex] [tex]x = 70[/tex]Step 4: Check if solution is correct.
[tex]2(70) - 5 + 45 = 180[/tex] [tex]140 - 5 + 45 = 180[/tex] [tex]135 + 45 = 180[/tex] [tex]180 = 180[/tex]Therefore, x = 70.
Is 3 to the second power + 3 to the 3rd power equal to 3 to the 5th power explain
Answer:
They are not equal.
Step-by-step explanation:
Hi there!
[tex]3^2+3^3[/tex] is not equal to [tex]3^5[/tex]. When two powers with the same base are added together, we cannot add the exponents to get the answer.
We can only add exponents to get the answer when two power with the same base are multiplied.
[tex]3^2+3^3\\= 9+27\\=36[/tex]
[tex]3^5\\=243[/tex]
They are not equal.

PLEASE help me answer this question!!
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.

Step-by-step explanation:
we need to find the slope of each line.
the slope is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.
parallel lines have the same slope.
for a perpendicular line x and y in the slope ratio are put upside down, and the sign is flipped (+ to - and vice versa).
a.
2x - 8y = -24
2x + 24 = 8y
y = 2/8 x + 24/8 = 1/4 x + 3
the slope is 1/4 (always the factor of x).
4x + y = -2
y = -4x - 2
the slope is -4 = -4/1.
this line is therefore perpendicular to the first line.
x - 4y = 4
x - 4 = 4y
y = 1/4 x - 4/4 = 1/4 x - 1
the slope is 1/4.
this line is therefore parallel to the first line.
b.
3x - 9y = 9
9y = 3x - 9
y = 3/9 x - 9/9 = 1/3 x - 1
the slope is 1/3
3y = x + 12
y = 1/3 x + 4
the slope is 1/3.
this line is therefore parallel to the first line.
2x - 6y = 12
6y = 2x - 12
y = 2/6 x - 12/6 = 1/3 x - 2
the slope is 1/3.
this line is therefore parallel to the first line.

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.

number of ways to divide up the money. Who is
correct? Prove their argument.
(I really need help, who is right, and tell me why please!)
Answer:
I think that Maya is right because the question doesn't state that they had to split it equally, you could split it infinite ways.

You buy 50 feet of fence to place around a rectangular yard. If the length of the yard is 13 feet, what is the constraint for the width of the yard? Let w represent width *
Step-by-step explanation:
a fence represents the circumference, the perimeter of the lot or yard.
remember, a rectangle has 2 parallel sides called the length, and 2 parallel sides called the width (altogether 4 sides).
therefore
perimeter = 2×length + 2×width
or with short variables
p = 2×l + 2×w
so, now we have 50 ft of fence available for the perimeter. and the length l = 13 ft.
since we have 2 lengths in the perimeter, these 13 ft are twice (2×13 = 26 ft) in the perimeter.
now, how much fence do we have left for the width ?
well, 50 - 26 = 24 ft
and again, this is the size of 2 sides (2×width) :
p = 2×l + 2×w
50 = 2×13 + 2×w = 26 + 2×w
2×w = 24
w = 12 ft
so, the width of the yard must not be bigger than 12 ft.

Answer:
32 square units
Step-by-step explanation:
You can split this shape into four different shapes:
2 unit by 2 unit triangle
2 unit by 2 unit square
2 unit by 6 unit triangle
To find the length of the big triangle, add the lengths of the small triangle,the square,and the bigger leg of the other triangle:
2 + 2 + 6 = 10
10 unit by 4 unit triangle
Then solve all these areas:
( 2 x 2 ) / 2 = 4 / 2 = 2
2 x 2 = 4
( 2 x 6 ) / 2 = 12 / 2 = 6
( 10 x 4 ) / 2 = 40 / 2 = 20
Then add all these areas together to get the total area of the composite shape:
2 + 4 + 6 + 20 = 32
