Answer:
y = 3x - 4
Step-by-step explanation
If the line is perpendicular, then it means that the slope will be opposite. So if it's -1/3 then it will become 3.
y = 3x + b
-1 = 3(1) + b
-1 = 3 + b
-4 = b
The equation is y = 3x - 4

how many sides a hetergon got
Answer:
6
Step-by-step explanation:
answer:
so there isnt such thing as a hertergon but if your looking for how much sides does a heptagon have
the answer is 7 !
ill add a photo here for you to see just in case i got the shape you were looking for wrong
but there isnt really any way to see how much sides a shape does have, the easiest way is to count the sides!

A property worth 10,480.00 is shared between Eugenia and her 10 brothers in ratio: 1:4 respectively.The 10 brothers shared their portion equally.Find each the brothers share.
Answer:
838.4
Step-by-step explanation:
From the question,
Total worth of the property = 10480.
Eugenia share: Her 10 brothers share = 1:4
Total ratio = 1+4 = 5.
Her 10 brother's share = (4/5)(10480)
Her 10 brother's share = 41920/5
Her 10 brother's share = 8384.
If the 10 brothers shared their portion equally,
Each brother's share = 8384/10
Each brother's share = 838.4
Verify the equation: (sin x + cos x)(tan x + cot x) = sec x csc x
Answer:
The equation (sin(x) + cos(x))(tan(x) + cot(x)) = sec(x)csc(x) is not solvable because the two sides are not equal.

QUESTION 4
Factorise fully:
4.1.1
12x² – x - 6
Answer:
y = (4x - 3)(3x + 2)
Step-by-step explanation:
Factorization is the process of taking like terms out of number such that one can rewrite an expression by its factors, or as the products of serval smaller expressions.
The first step to factoring an equation is to rewrite the linear term as the sum or difference of two other linear terms. One must do this in such as way that it shares a common factor with one of the other terms in the expression.
[tex]12x^2 -x - 6[/tex]
[tex]12x^2 -9x + 8x - 6[/tex]
Take out the common factor,
[tex]3x(4x-3)+2(4x-3)[/tex]
Factor,
[tex](3x+2)(4x-3)[/tex]

Indices and Standard Form question
Answer:
A= 4.5×10^11
B= 3.5×10^3
Step-by-step explanation:
A
(5×10^3)= 5000
(9×10^7)=90000000
multiply both of them
=450000000000 or 4.5×10^11
B
(7×10^5)=700000
(2×10^2)=200
700000÷200
3500 or 3.5×10^3

Sarah is self-publishing her 300-page novel and wants to estimate the printing costs.
Answer the questions to estimate the cost of printing a 300-page paperback book.
1. What is the y-intercept for the trend line? What is the real-world meaning of this point?
2. One point on the trend line is (200, 6). Using this point and the y-intercept, find the slope of the trend line. Show your work.
3. What is the real-world meaning.of the slope?
4. Use the slope and y-intercept to write an equation for the trend line in slope-intercept form.
5. Use your equation to estimate the cost of printing Sarah's 300-page book.
1. Y-intercept b=5
That means it has a 5.00 starting fee.
2. Using the formula (Y2-Y1)/(X2-X1) we will find the slope between the two points.
Point one (X1 and Y1) will be the Y-intercept.
X1,Y1 = (0, 5.00)
Point 2 (X2 and Y2) will be the point on the trend line.
X2, Y2 = (200, 6.00)
Plug in:
(6.00 - 5.00)/(200 - 0) = 00.5 or 1/200.
3. When printing 200 pages each page will cost $.005.
4. .005x+5
5. .005x+5
.005(300)+5=6.5
good luck♡♡!!

At a hospital emergency room, a doctor has determined that for every 14
patients injured in a car accident, 6 were not wearing seat belts.
6 no seat belts
14 injured total
If the emergency room saw 420 patients injured in car accidents last
month, what is the best prediction for how many patients were not wearing
seat belts? Round to the nearest WHOLE person.
6 no seat belts = ? no seat belts
___________ ___________
14 injured total 412 injured total
Answer:
A prediction of 177 people.
Step-by-step explanation:
6x412=2472
2472/14=176.571428571

A rectangle’s length is three times its width, w. Its area is 243 square units. Which equation can be used to find the width of the rectangle?
a. w2 = 3(243)
b. 3w2 = 243
c. 4w2 = 243
d. 3w2 = 3(243)
please im on a timed test
Answer:
b) 3w² = 243
Step-by-step explanation:
area = L x w
L = 3w
substitute for L:
243 = 3w x w = 3w²
3w² = 243

Students in an Introductory Statistics class at BYU-Idaho were studying prices of cold cereal at grocery stores in Rexburg. To get a sample of cold cereal prices, they went to Albertson's and rolled a die to decide which box from the left of the top shelf they would start on. They then recorded every 6th cereal after the first, moving from left to right down the shelves, recording the name, size, and price of each cereal in their sample. Is this study an experiment or an observational study, and why
Answer: Observational study
Step-by-step explanation:
The study illustrated in the question is an observational study. It is referred to as an observational study, because in this case, the price of the individual cereals us not being controlled by the students. They've no control over it.
If it was an experiment, there'll have been a control group and the students will have control over the price. Also, the sampling methods used here is a systematic random sampling.
What is the line of symmetry for the parabola whose equation is y = x2 + 10x + 25?
A-x = -5
B-x = 5
C-x = -10
Answer:
x = -5
Step-by-step explanation:
Please write this as y = x^2 + 10x + 25. Here the coefficients are {1, 10, 25}.
The equation of the axis of symmetry is x = -b/[2a], which here is
x = -10 / [2*1] = -5

Answer:
48
Step-by-step explanation:
The nth term of an AP is expressed as;
Tn = a+(n-1)d
Id 12th term is 32, hence;
T12 = a+11d
32 = a+11d ...1
If the 5th term is 18, then;
T5 = a+4d
18 = a + 4d ....2
Subtract 1 from 2;
32 - 18 = 11d - 4d
14 = 7d
d = 14/7
d = 2
From 1; 32 = a+11d
32 = a+ 11(2)
32 = a + 22
a = 32-22
a = 10
Get the 20th term
T20 = a+19d
T20 = 10 + 19(2)
T20 = 10 + 38
T20 = 48
Hence the 20th term is 48
