Line b has a slope of
Line c is parallel to line b. What is the slope of line c?
Answers
Answer:
[tex]\frac{-5}{9}[/tex]
Step-by-step explanation:
The slope of two parallel lines is the same. As long as the y-intercept is different then, the lines are parallel. Therefore, if the slope of line b is [tex]\frac{-5}{9}[/tex] then the slope of line c must also be [tex]\frac{-5}{9}[/tex].

Find the inverse function of f(x)=15x-1
Answers
Answer:
f'(x) = (x + 1)/15
Step-by-step explanation:
f(x) = 15x -1,
Think of the term "f(x)" as a single variable, then solve for the term "x", manipulate the equation like how one would manipulate a literal equation, by inverse operations.
f(x) = 15x - 1
+1 +1
f(x) + 1 = 15x
/15 /15
(f(x) + 1)/15 = x
This means that (denote in the way one would denote an inverse of a function);
f'(x) = (x + 1)/15
Prove that (Root of Sec A - 1 / Root of Sec A + 1) + (Root of Sec A + 1 / Root of Sec A - 1) = 2 cosec A
Answers
Answer:
The answer is below
Step-by-step explanation:
We need to prove that:
(Root of Sec A - 1 / Root of Sec A + 1) + (Root of Sec A + 1 / Root of Sec A - 1) = 2 cosec A.
Firstly, 1 / cos A = sec A, 1 / sin A = cosec A and tanA = sinA / cosA.
Also, 1 + tan²A = sec²A; sec²A - 1 = tan²A
[tex]\frac{\sqrt{secA-1} }{\sqrt{secA+1} } +\frac{\sqrt{secA+1} }{\sqrt{secA-1} } =\frac{(\sqrt{secA-1)}(\sqrt{secA-1})+(\sqrt{secA+1)}(\sqrt{secA+1}) }{(\sqrt{secA+1})(\sqrt{secA-1}) } \\\\=\frac{secA-1+(secA+1)}{\sqrt{sec^2A-secA+secA-1} } \\\\=\frac{2secA}{\sqrt{sec^2A-1} } \\\\=\frac{2secA}{\sqrt{tan^2A} } \\\\=\frac{2secA}{tanA} \\\\=\frac{2*\frac{1}{cosA} }{\frac{sinA}{cosA} }\\\\= 2*\frac{1}{cosA}*\frac{cosA}{sinA}\\\\=2*\frac{1}{sinAA}\\\\=2cosecA[/tex]
Half the area of the rectangle shown is 24 square inches. Write and solve an equation to find the value

(x + 2) in
Equation:
X=
2
Answers
Answer:
Step-by-step explanation:
Half the area of the rectangle shown is 24 square inches. Then value of x is 6
What is Area of Rectangle?The area of Rectangle is length times of width.
Area = length x width.
24 = (x + 2)(x - 3) = x² - x - 6
x² - x - 30 = 0
(x + 5)(x - 6) = 0
We can eliminate the root x = - 5 because dimensions cannot be negative. So, the only valid answer is x = 6
The length = x + 2 = 6 + 2 = 8 in.
The width = x - 3 = 6 - 3 = 3 in
Hence, the value of x is 6.

Step-by-step explanation:
First find the whole, the total number of attendees:

The question asks what \textit{percent}percent of all the attendees is 714

-2+3x=-x-6 combine liked terms (added x & 2 to each side)
+2 +x +x +2
4x = -4 isolate x (divide 4 from each side)
x = -1
Answer:
X=-1
Step-by-step explanation:
First, add 2 on both sides to eliminate -2 and to get 3x alone. Now you have the product of 3x=-x-4. Next, add x on both sides to isolate negative 4. Once, you have done this you get 4x=-4. Now you divide by 4 to get x alone. And you get the product x= -1.

What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
Given the preimage of a parallelogram with vertices (1,5), (3,3), (3,7), and (5,5).
If we plot in the coordinate plane as shown below.
Now plot the image of a parallelogram with vertices (−5,3), (−3,1), (−3,5), and (−1,3).
If we take only one vertex of the preimage to let's say (1,5) now if we look at the corresponding vertex in the image then it is (-5,3).
1 + x = -5 ⇒ x = -6 (6 units left)
5 + y = 3 ⇒ y = -2 (2 units down)
Hence "The actual image of the parallelogram has been translated by 6 units left and 2 units down of the preimage parallelogram".

A cyclist travels 5 miles in the direction N 30° E, then travels 3 miles in the direction N 70° E. Which equation
measures the cyclist's distance, x, from the starting point?
52 = x2 + 32 – 2(3)(x)cos(100°)
52 = x2 + 32 – 2(3)(x)cos(140°)
x2 = 52 + 32 – 2(5)(3)cos(100’)
x2 = 52 + 32 – 2(5)(3)cos(140°)
Answers
Answer:
D. x2 = 52 + 32 – 2(5)(3)cos(140°)
Step-by-step explanation:
The equation measures the cyclist's distance, x, from the starting point will be x²=5²+3²-2(5)(3)cos(140°). Option B is corect.
What is the distance?Distance is a numerical representation of the distance between two objects or locations.
The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
Distance is measured in the meter, centimeter, miles, nautical mile, feet, etc. The unit of distance is most important to find it.
The distance, x, from the starting point is;
From the cos law ;
x² = a² +b²-2ab cosΘ
From the digrame it is obtained that;
a =5
b =3
Θ = 180 ° +70° -30°
Θ = 180°- 40°
Θ = 140°
Substitute the values;
x² = a² +b²-2ab cosΘ
x²=5²+3²-2(5)(3)cos(140°)
The equation measures the cyclist's distance, x, from the starting point will be x²=5²+3²-2(5)(3)cos(140°).
Hence option B is corect.

(Angles in a triangle add up to 180 degrees.)
Answers
Answer:
Angle A = 102°
Angle B = 51°
Angle C = 27°
Step-by-step explanation:
angle A = 2b
angle B = b
angle C = 1/3 b + 10
Angle A + Angle B + Angle C = 180
2b + b + 1/3 b + 10 = 180
3 1/3 b + 10 = 180
10/3 b = 170
b = 51
a = 2b = 102
c = 1/3 b + 10 = 1/3 (51) + 10 = 17 + 10 = 27

Joey Chestnut is trying to break his own record for eating the most whole hot dogs in 10 minutes. He needs to eat more than 72 hot dogs to break his record. After 1 minute, Joey has eaten 11 1/4 hot dogs. Let ddd represent the number of hot dogs Joey eats per minute for the next 999 minutes. Which inequality represents the number of hot dogs per minute Joey could eat for the last 999 minutes to break his record?
Answers
Answer:
d > 6 3/4
Step-by-step explanation:
Given that:
72 hot dogs in 10 minutes is required to break Record ;
Consumption after 1 minute = 11 1/4 hot dogs
Number of hotdogs consumed per minute for the next 9 minutes = d
Number of consumption per minute required to break record :
d = (72 - 11 1/4) / 9
d = (60 3/4) ÷ 9
d = (243 / 4) * 1/9
d = 243 / 36
d = 6 3/4 hotdogs per minute
Hence, to break record. Consumption must be > 72 hotdogs in 10 minutes
Hence,
d > 6 3/4

A phone company offers to monthly plans. Plan a cost $23 plus an additional $.08 for each minute of calls. Plan B cost $19 an additional $.12 for each minute of calls.
Answers
Answer:
The indifference point is 100 minutes.
Step-by-step explanation:
Giving the following information:
Plan a cost $23 plus an additional $.08 for each minute of calls.
Plan B cost $19 an additional $.12 for each minute of calls.
First, we need to establish the total cost formula for each plan:
Plan A= 23 + 0.08*x
Plan B= 19 + 0.12*x
x= number of minutes
Now, to calculate the indifference point, we equal both formulas and isolate x:
23 + 0.08x = 19 + 0.12x
4 = 0.04x
100= x
The indifference point is 100 minutes.
Prove:
Plan A= 23 + 0.08*100= $31
Plan B= 19 + 0.12*100= $31
