Answer:
Step-by-step explanation:
Let function p(x) be the price that is reduced by 15% if the bill is x dollars.
Since the price is not payed in full 100% is reduced by 15% we only pay
100 - 15 = 85 % of the original price.
p(x) = x· (100% - 15 %) = x· 85% = 0.85 x
The function used to calculate any bill that is reduced by 15% is:
p(x) = 0.85x
x - is the bill before being reduced by the coupon

Isosceles triangle ABC contains angle bisectors segment BF, segment AD, and segment CE that intersect at X.
If segment BA is congruent to segment BC and m∠BCA = 48°, what is m∠CXA?
132°
96°
66°
24°
Answer:
The measure of angle CXA is 134°
Step-by-step explanation:
* Lets explain how to solve the problem
- Triangle ABC is an isosceles triangle where AB = BC
∵ AB = BC
- The base angles in the isosceles triangle are congruent
∴ m∠BAC = m∠BCA
∵ m∠ BCA = 46° ⇒ given
∴ m∠ BAC = 46°
- The sum of the measures of the interior angles in any triangle is 180°
∵ m∠BAC + m∠BCA + m∠ABC = 180°
- Substitute the values of angle BAC and BCA in the equation above
∴ 46 + 46 + m∠ABC = 180
∴ 92 + m∠ABC = 180
- Subtract 92 from both sides
∴ m∠ABC = 88°
- BF , AD , CE are bisectors segments of angles B , A , C and they are
intersected at point X
∵ CE bisects ∠BCA
∵ X ∈ CE
∴ m∠XCA = 1/2 m∠BCA
∴ m∠XCA = 1/2 (46) = 23°
∵ AD bisects ∠BAC
∵ X ∈ AD
∴ m∠XAC = 1/2 m∠BAC
∴ m∠XAC = 1/2 (46) = 23°
- In Δ AXC
∵ m∠XAC = 23° ⇒ proved
∵ m∠XCA = 23° ⇒ proved
∵ m∠CXA + m∠XAC + m∠XCA = 180° ⇒ interior angles of Δ
Substitute the values of angles XAC and XCA
∴ m∠AXC + 23 + 23 = 180
∴ m∠CXA + 46 = 180
- Subtract 46 from both sides
∴ m∠CXA = 134°
* The measure of angle CXA is 134°
Answer: I also have this question and because everybody is saying 134 I believe it is 132. So I hope this helps.

PLEASE HELP 88 POINTS Alejandro volunteers on the weekend at the Central Library. As a school project, he decides to record how many people visit the library, and where they go. On Saturday, 463 people went to The Youth Wing, 474 people went to Social Issues, and 335 went to Fiction and Literature. On Sunday, the library had 1100 total visitors. Based on what Alejandro had recorded on Saturday, about how many people should be expected to go to The Youth Wing? Round your answer to the nearest whole number.
Answer:
401 people
Step-by-step explanation:
First, find the percentage of students that went to the Youth Wing on Saturday, this is 463/463+474+335
464/1272
=36.4779874%
Multiply it now by the Sunday visitors, 0.364779874 x 1100
= 401.2578616
=401 people
Answer: 400
Step-by-step explanation:
Find the equation of the line that goes through the point (1, -1) and has a slope of 5.
y = 5x - 6
y = 5x + 1
y = 5x - 1
y = x + 5
The equation of the line that goes through the point (1, -1) and has a slope of 5 is y = 5x - 6
How to find linear equation of a line?The linear equation of a line is represented as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the line passes through (1, -1) and has a slope of 5.
Using the model y = mx + b,
y = 5x + b
let's find b using (1, -1)
- 1 = 5(1) + b
-1 - 5 = b
b = -6
Therefore, the equation of the line that goes through the point (1, -1) and has a slope of 5 is y = 5x - 6

Answer:
y=5x-1
Step-by-step explanation:
Slope is represented as m. y-intercept is represented as b. And ordered pairs are written in the form x,y. So you ignore the first 1 in your ordered pairs and just look at the second one because the second one represents the y-intercept.

A motor center carries out servicing of cars, which includes the replacement of parts.
Three service technicians can each do 5 services per day . Normally they work Monday to Friday, but
sometimes one technician will also work on Saturday.
Each car requires 1 air filter, 1 oil filter, 1 quantity of engine oil and 4 spark plugs.
The parts are purchased in bulk, and come in boxes containing the quantities shown below.
Air filter............. 8 per box
Oil filter ............ 20 per box
Engine oil ......... 4 per box
Spark plugs ...... 80 per box
How many boxes of each item is it necessary to buy each week, if the motor center is to carry out the maximum possible number of services?
Answer:
1 box of spark plugs, 3 air filter boxes, 1 oil filter box, and 5 boxes of engine oil
Step-by-step explanation:
the max amount of services that can be done is about 20 per week, including the one on Saturday. so u just multiply the amount needed by the 20 possible services and check to see the amount that comes in each box, then get as many as needed

Which expression has the same value as -8+(-7)? F-8-(-7) G -8+7 H -7-(-8) J -7-8
Answer:
Choice J
[tex]-8 + (-7) = -7-8[/tex]
Answer:
The answer is Option J
Step-by-step explanation:
(-8) + (-7) = (-8) – 7 = (-15)
(F) (-8) – (-7) = (-8) + 7 = (-1)
(G) (-8) + 7 = (-1)
(H) (-7) – (-8) = (-7) + 8 = 1
(J) (-7) – 8 = (-15)
Thus, Option (J) has the same value as (-8) + (-7).
5x + 2y = 8
-4x + 10y = 40
Answer:
(0, 4 )
Step-by-step explanation:
5x + 2y = 8 → (1)
- 4x + 10y = 40 → (2)
multiplying (1) by - 5 and adding to (2) will eliminate y
- 25x - 10y = - 40 → (3)
add (2) and (3) term by term to eliminate y
- 29x = 0 , then
x = 0
substitute x = 0 into (1) and solve for y
5(0) + 2y = 8
0 + 2y = 8
2y = 8 ( divide both sides by 2 )
y = 4
solution is (0, 4 )

The equation of line is y = ( 1/2 ) mv² , where m is the mass of the student and y is the kinetic energy
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let y represent the kinetic energy and mass is m
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
The equation for kinetic energy is K = ( 1/2 )mv²
The constant speed v = 3 m/s
So , the linear equation is
y = { 121.5 , 162 , 202.5 , 243 , 288 , 328.5 }
x = { 27 , 36 , 45 , 54 , 64 , 73 }
The slope m = y / x
On simplifying , we get
m = 121.5 / 27 = 4.5
And , the equation of line is
y - 121.5 = 4.5 ( x - 27 )
Adding 121.5 on both sides , we get
y = 4.5x
Now , plotting the points on the graph , we get a straight line
Hence , the equation of line is solved and the graph is plotted
