*Instead of rewriting PF to QF +43 in part (a), you could also leave PF as it is and rewrite QF as PF -43 after the line I labelled as equation 2. The working would be about the same, just that you would not need to add 43 again in picture 3 because we would be working with PF. (PF would be factorised out instead)

800 students are going on a school trip by bus.
Each bus can carry 34 students.
Work out the smallest number of buses needed to carry all the students.
Answer:
24 buses
Step-by-step explanation:
In order to find the answer, we need to divide the number of students by the capacity of each bus. There are 800 students and each bus carries 34.
800/34=23.5
Since we can't have half of a bus, we round up to 24.
24 buses

Four consecutive odd integers have the sum of 80. Find the integers.
Answer:
Step-by-step explanation:
let 4 no:s be x, 3x, 5x, 7x
given, x+3x+5x+7x=80
16x = 80
x = 80/16
therefore, x=5
so, x=5
3x=15
5x= 25
7x= 35

8. Why is it NOT useful to view science as a set of facts?
This is my honest opinion
Science is not just facts. Science, to me, is full of theories and hypotheses that can be proved wrong. Yes, a majority of it is actually factual, but in the future it may or may not be true.
I hope it helps.
If f(x) = 2x -1, what does f(10) equal?
-1

Asap pls
Step-by-step explanation:
f(x) = 2x - 1
f(10) = 2(10) - 1

Graph [tex]g(x)=\frac{1}{2}|x+2|-3[/tex] as a transformation of [tex]f(x)=|x|[/tex]. Then identify the transformation.
Answer:
see below
Step-by-step explanation:
g(x) = 1/2 | x+2| -3
y = Cf(x) 0 < C < 1 compresses it in the y-direction
y = f(x + C) C > 0 moves it left
y = f(x) + C C < 0 moves it down
1/2 compression in the y direction moved to the left 2 units and down 3 units
Given: g(x) = 1/2|x + 2| - 3
0 < c < 1 means at the y-axis and makes it smaller
y = cf(x)
1/2 compression
c > 0 means that you move it to the left
y = f(x + c)
2 units to the left
c < 0 means that you move it down
y = f(x) + c
3 units down
Best of Luck!
Graph a line that contains the point (6,-5)
Answer:
y=-5
Step-by-step explanation:
It must contain (6, -5). Therefore, I went the easy way and created a line that has y = -5 no matter what x is. You can put 0x-5 if you want to make sure the independent variable is x.
Will switching points when calculating distance affect the final answer? Explain. (1 point)
Switching points when calculating distance will affect the final answer because the formula adds the differences of the corresponding X-
and y-values
Switching points when calculating distance will not affect the final answer because the formula adds the differences of the
corresponding X- and y-values.
Switching points when calculating distance will affect the final answer because the formula finds the differences of the corresponding x-
and y-values
Switching points when calculating distance will not affect the final answer because the formula squares the differences of the
corresponding X- and y-values.
Answer:b
Step-by-step explanation:
Consider the steps to solve the equation. 2 5 ( 1 2 y + 20 ) − 4 5 = 9 20 (2y − 1) Distribute: 1 5 y + 8 − 4 5 = 9 10 y − 9 20 What is the next step after using the distributive property? Use the multiplication property of equality to isolate the variable term on one side of the equation. Use the multiplication property of equality to isolate the constant on one side of the equation. Combine the like terms on the right side of the equation. Combine the like terms on the left side of the equation.
Answer: D

The correct answer is d. Combine the like terms on the left side of the equation.
Solve 3(x + 6) - 2(x - 2) ≥ 10
Answer: x ≥ -12
Step-by-step explanation:
Step 1: Simplify both sides
x+22 ≥ 10
Step 2: Subtract 22 from both sides
x + 22 −22 ≥ 10 −22
Your answer should be
x ≥ −12

A baby elephant named Nora was born at a wildlife refuge and weighed 200 lbs when she was
born and gained 22 lbs every week. In preparation for her birth, the staff estimated how much
she would weigh at certain weeks so they could stock some of her food ahead of time. They
documented that at 16 weeks she would weigh approximately 352 lbs. Did they estimate
correctly? If so, explain why. If not, describe what they did wrong and find her accurate weight.
Answer:
352 lbs is correct
Step-by-step explanation:
They did estimate correctly. for how to do this look below:
So we have a elephant that gains 22 pounds every week and they estimated that at 16 week she would be at 352 lbs
22 which was current pounds at the time and she would keep gaining that every week for 16 weeks
So weight times weeks
22*16
22*16= 352

Point C is on line segment \overline{BD} BD . Given CD=2x,CD=2x, BD=3x+4,BD=3x+4, and BC=2x-1,BC=2x−1, determine the numerical length of \overline{BD}. BD
Answer:
[tex]BD = 19[/tex]
Step-by-step explanation:
Given
[tex]CD = 2x[/tex]
[tex]BD = 3x + 4[/tex]
[tex]BC = 2x -1[/tex]
Required
Find BD
Since C is on BD, we have:
[tex]BD = BC + CD[/tex]
Substitute values for BD, BC and Cd
[tex]3x + 4 = 2x - 1 + 2x[/tex]
Collect Like Terms
[tex]3x - 2x - 2x = -1 - 4[/tex]
[tex]-x = -5[/tex]
Multiply through by -1
[tex]x = 5[/tex]
Substitute 5 for x in [tex]BD = 3x + 4[/tex]
[tex]BD = 3 * 5 + 4[/tex]
[tex]BD = 19[/tex]

If a line contains the point (0,-1) and has a slope of 2 what point is on the line A.(2,1) B.(1,1) C.(0,1)
Answer: B. (1,1)
Step-by-step explanation: If you find slope with the points (0,-1) and (1,1) you will get a slope of 2.
the formula you can use is y2-y1/x2-x1
substitute the values with the 2 points i mentioned
1-(-1)=2
1-0=1
divide 2/1
and you get 2
So B, (1,1) would be your answer.
A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 6 feet per second. The elevator for the miners descends 16 feet per second. One day, the equipment elevator begins to descend. After 28 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 14 seconds? At that time, which elevator is deeper?
Answer:
equipment: -252 feet; miners: -224 feetequipment is deeperStep-by-step explanation:
The attached graph shows the depth of the elevators with respect to the time the miners' elevator started.
After 14 more seconds, the positions are ...
equipment: -6(42) = -252 feet relative to the surface
miners: -16(14) = -224 feet relative to the surface
The equipment elevator is deeper.
what is equivalent to 2 5/9
Answer:
2.555555 ....
Step-by-step explanation:
2 5/9 is a mixed number.
Use your calculator to divide 9 into 5, to find the value of 5/9. Then add 2 to the result:
5/9 = 0.5555555 (repeating fraction)
Adding 2, we get:
2.555555 .... (repeating fraction)
