Which expression is equivalent to the following complex fraction? StartFraction 2 Over x EndFraction minus StartFraction 4 Over y EndFraction divided by StartFraction negative 5 Over y EndFraction + StartFraction 3 Over x EndFraction StartFraction 3 y + 5 x Over 2 (y minus 2 x) EndFraction StartFraction 2 (y minus 2 x) Over 3 y minus 5 x EndFraction StartFraction 2 (y minus 2 x) (3 y minus 5 x) Over x squared y squared EndFraction StartFraction x squared y squared Over 2 (y minus 2 x) (3 y minus 5 x) EndFraction
Answer:
A
Step-by-step explanation:
The equivalent expression of the complex fraction is [tex]\frac {2y - 4x}{5x + 3y}[/tex]
What are equivalent expressions?Equivalent expressions are expressions that have equal values, when compared
The expression is given as:
[tex](\frac 2x -\frac 4y) \div (\frac 5y + \frac 3x)[/tex]
Take LCM
[tex](\frac {2y - 4x}{xy}) \div (\frac {5x + 3y}{xy})[/tex]
Express the quotient as products
[tex](\frac {2y - 4x}{xy}) * (\frac {xy}{5x + 3y})[/tex]
Evaluate the product
[tex]\frac {2y - 4x}{5x + 3y}[/tex]
Hence, the equivalent expression of the complex fraction is [tex]\frac {2y - 4x}{5x + 3y}[/tex]

For the function, find the points on the graph at which the tangent line is horizontal. If none exist, state that fact. SHOW WORK PLEASE!
9514 1404 393
Answer:
A. (-√2, 3+(4√2)/3), (√2, 3-(4√2)/3)
Step-by-step explanation:
The tangents are horizontal where the derivative is zero. The derivative of the given function is ...
y' = x² -2
This is zero when ...
0 = x² -2
2 = x²
±√2 = x . . . . x-values where the derivative is zero
__
The corresponding y-values are ...
y = (1/3x² -2)x +3
y = (1/3(2) -2)(±√2) +3 = 3 ∓ (4√2)/3
The turning points are (-√2, 3+(4√2)/3) and (√2, 3-(4√2)/3).

[tex]-\frac{1}{2} *(-\frac{5}{6} )+(-\frac{1}{2} )*\frac{1}{3} \\=\frac{5}{12} -\frac{1}{6} \\=\frac{5}{12} -\frac{2}{12} \\=\frac{3}{12} \\\frac{1}{4}[/tex]
Answer:
it's 5/12 + 1/3
Step-by-step explanation:
you would multiply the -5/6 by -1/2 to get 5/12 since the negative would cancel out
so 5/12 + 1/3 would be the answer.
Also this question doesn't make any sense since you are supposed to simplify the parentheses first.

Which expression represents the perimeter of a rhombus with diagonal lengths 8a and 10a?
Answer:
4a[tex]\sqrt{x}[/tex]41
Step-by-step explanation:
12*2+9x2= Perimeter.
The perimeter P of rhombus is given as
[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]
The diagonals of rhombus bisect each other at right angles and it has same perimeter as that of a square.
From this property stated above we can formulate side of rhombus is below in equation (1)
Side and diagonals of rhombus have following relation
[tex]\rm Let \; the \; side \; of\; rhombus = s\\Length\; of \; first \; diagonal = 8a\\ Length\; of \; second \; diagonal = 10a\\\\According \; to \; the \; identity\; for\; area \; of\; rhombus \\ s^2 = (p/2)^2 +(q/2)^2 ....(1) \\where \; p \; and\; q \; are\; the \; diagonals.[/tex]
so
[tex]\rm s^2 = (10a/2)^2 + (8a/2)^2\\s^2 = 25a^2 + 16a^2 = 41 a^2 \\s= \sqrt{41}a ......(2)[/tex]
Equation (2) represents side of rhombus
So the perimeter P of rhombus is given as
[tex]\rm P = 4\times s[/tex]
[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]
The perimeter P of rhombus is given as
[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]

Geomotry 10th grade easy 25 points
Answer: 1=60°
Step-by-step explanation:
First, let's take our given angle of 30°
30° is in a right triangle, so the angles must be 90°, 60°, and 30°
Now the angle that is 45° makes angle 1 congruent to angle 60°
Meaning angle 1 is 60°
Answer:
m < 1 = 60
Step-by-step explanation:
Since the transversal is perpendicular to m,
it implies that the triangle formed by the perpendicular transversal, the slant transversal and the line m is a right angle triangle.
We use vertically opposite angles property to bring m<1 in to the right triangle.
We now use the sum of interior angles property to obtain,
m < 1 + 30 + 90 = 180
This implies that,
m < 1 + 120 + 180
We group like terms to obtain,
m < 1 = 180 - 120
This means that,
m < 1 = 60
We could have also used corresponding angles property, then
m < 1 + 30 = 90
m < 1 = 90 - 30
m < 1 = 60

Alright fam, help me out here with these angles thanks!
Answer:
m∠3 = 127°
Step-by-step explanation:
From the given picture,
Two parallel lines have been given.
Angle 3 and another angle measuring 53° are located on a point of a straight line.
Therefore, both the angles will be supplementary.
m(∠3) + 53° = 180° [Property of supplementary angles]
m(∠3) = 180° - 53°
= 127°

Negative 2.5 x greater-than-or-equal-to negative 30. x greater-than-or-equal-to 12.What error, if any, did Soro make when writing or solving this inequality
Answer:

Step-by-step explanation:
Soro bought a $50.00 bus card at the beginning of the week. Each bus ride costs $2.50. He needs to have at least $20.00 on his card at the end of this month.
Let her number of rides he can take be written as x
$50 - $2.50 × x ≥ $20
50 - 2.5x ≥ 20
-2.5x ≥ 20 - 50
-2.5x ≥ -30
x ≥ -30/-2.5
x ≥ 12 rides

Answer:
The picture is kinda blurry so I hope I've got it right.
a) x = 20°
b) x = 70°
c) x = 50°
Step-by-step explanation:
a) 2x + 3x + 4x = 180°
9x = 180°
x = 50°
b) (x - 20°) + (x - 20°) + (x + 10°) = 180°
3x - 30° = 180°
3x = 210°
x = 70°
c) (x + 10°) + (x + 20°) + x = 180°
3x + 30° = 180°
3x = 150°
x = 50°
