Solve for r 5(r-10)=-51
Answer:
r=−1/5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(r−10)=−51
(5)(r)+(5)(−10)=−51(Distribute)
5r+−50=−51
5r−50=−51
Step 2: Add 50 to both sides.
5r−50+50=−51+50
5r=−1Step 3: Divide both sides by 5.
5r/5=−1/5
r=−1/5
Answer:
r = - ¹/₅ or -0.2Step-by-step explanation:
5(r - 10) = -51
5r - 50 = -51
5r = -51 + 50
5r = -1
r = - ¹/₅ or 0.2

Option D is the correct answer.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = 1/ cosec x
Cos x = 1/ sec x
Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x
We have,
y = cos x
Cos π = cos (π/2 + π/2) = Sin π/2 = 1
Cos 2π = Cos (π + π) = - Cos π = - Cos (π/2 + π/2) = - Sin π/2 = -1
We see that,
y = Cos x is strictly increasing from -1 to 1.
Thus,
y = cos x is strictly increasing from π < x < 2π.

G.CO.5: Quadrilateral PQRS is shown on the coordinate plane.
Part A:
Quadrilateral PQRS is transformed by
translating it right 6 units and then
rotating it 90° clockwise about the
origin. Graph the image of
quadrilateral PQRS after these two
transformations.
9514 1404 393
Answer:
see attached
Step-by-step explanation:
Translation right 6 units adds 6 to every x-coordinate. Rotation 90° CW is the transformation (x, y) ⇒ (y, -x). The sequence of transformations gives ...
(x, y) ⇒ (y, -x-6)
Then the coordinates of the transformed figure are ...
P(-3, 7) ⇒ P'(7, -3)
Q(4, 12) ⇒ Q'(12, -10)
R(4, -2) ⇒ R'(-2, -10)

CAN SOMEONE PLEASE HELP ME ASAP PLEASEE ANYBODY LITERALLY ANYONE OUT THERE PLEASE. Determine m∠FNT and Determine m∠KTU.
Answer:
Angle FNT = 120 Degrees because the angles labeled 7a+50 and 14a-20 are the same because the lines are parralel so you can set them equal to eachother 7a+50=14a-20 and find that a=10 After this you plug 10 into either 7a+50 and 14a-20 to get 120. You know Angle FNT is 120 degrees because it is directly across from 7a+50 which means they are the same. Then the measure of Angle KTU is 60 because Angle KTN + Angle KTU needs to add up to 180.

Denote the Least Common Multiple by L.C.M
Denote the Left Multiplier by Left_M
Denote the Right Multiplier by Right_M
Denote the Left Deniminator by L_Deno
Denote the Right Multiplier by R_Deno
Left_M = L.C.M / L_Deno = 3
Right_M = L.C.M / R_Deno = 4
Making Equivalent Fractions :
3.3 Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. 117 • 3
—————————————————— = ———————
L.C.M 48
R. Mult. • R. Num. 47 • 4
—————————————————— = ——————

3.4 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

Insert two geometric means between 729 and 64
Answer:
324 and 144
Step-by-step explanation:
We require
a₁, a₂, a₃, a₄
where a₂ and a₃ are the required geometric means
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 729 and a₄ = 64, thus
729(r³) = 64 ( divide both sides by 729 )
r³ = [tex]\frac{64}{729}[/tex] ( take the cube root of both sides )
r = [tex]\sqrt[3]{\frac{64}{729} }[/tex] = [tex]\frac{4}{9}[/tex] , then
a₂ = 729 × [tex]\frac{4}{9}[/tex] = 81 × 4 = 324
a₃ = 324 × [tex]\frac{4}{9}[/tex] = 36 × 4 = 144
Thus
729, 324, 144, 64

How can you solve a system of two equations or inequalities in which one is linear and one is quadratic?
Answer:
Solve the inequality as though it were an equation. The real solutions to the equation become boundary points for the solution to the inequality. Make the boundary points solid circles if the original inequality includes equality; otherwise, make the boundary points open circles.

Moesha and Keyon are mailing invitations for their wedding. They have $50 to spend and each invitation costs $1.25 to mail. The function m=50−1.25w represents the amount of money m Moesha and Keyon have left after mailing w wedding invitations. Find the zero of the function. Describe what this value means in the context of this situation.
Answer:
The zero of the equation is 40
It means the number of wedding invitations they can send based on their budget
Step-by-step explanation:
To determine the zero of the function, we simply set the dependent variable ( m in this case) to zero.
Thus, mathematically;
0 = 50-1.25w
1.25w = 50
w = 50/1.25
w = 40
So what does this mean in the context of the situation?
What it means is that the total number of people they would be able to send the mail to based on their budget is 40
Answer:
The zero of the function is at
40. This represents that after mailing 40 wedding invitations, Moesha and Keyon will $ 0 left.

A point moves in the plane in the following sequence.
A point moves down 2 units, reflects over the x-axis, moves right 4 units, and then reflects over the y-axis.
Which of the following points follows the sequence and has the same starting and ending point?
A. (2, 3)
B. (–1, 1)
C. (–3, –3)
D. (–2, 1)
Answer:
D
Step-by-step explanation:
The answer is point D(-2,1).
1. If the point D was moved down 2 units, then its coordinates became (-2,-1).
2. If point (-2,-1) was reflected over the x-axis, then its coordinates became (-2,1).
3. If the point (-2,1) was moved 4 units to the right, then its coordinates became (2,1).
4. If point (2,1) was reflected over y-axis, its coordinates became (-2,1).
A smartphone device has a certain cost. A person gets this smartphone and signs up for a monthly wireless plan with a fixed base price plus a charge per GB of data used. Which is the Independent Variable in this scenario? A. The cost of the smartphone device. B. The charge per GB of data used. C. The number of GB data used. D. The total amount they pay for the new device and new phone plan in the first month. Need an answer fast! Due very soon! Don't understand!
Answer:
The independent variable is: "the cost of the smart phone"
Step-by-step explanation:
An independent variable is simply one that doesn't depend on other variables measured in the same sentence.
Now, in the question, we are told that the smart phone device has a fixed cost. This means that the cost doesn't depend on any other variable mentioned in the sentence.
Thus, the independent variable is: "the cost of the smart phone"
Calculate the area of the triangle? What is the best way to solve it
Answer: Find the the height and length of the triangle. I'm not sure what it would be but then use a1 + a2 to find the area
Answer:
Formula of triangle: A = 1/2 x b x h
Step-by-step explanation:
Solve the base of the triangle by solving the distance between points (-2,0) and (f, -5) in units, and then do the same for height: find distance between points (-2, 6) and (-2, 0). Once you find the distance, input value of base and height into the formula and solve to get the area!
