Answer: -3/5, 18/32, -10/11, and horizontal.
Step-by-step explanation: Remember the equation for slope? Δy (the change in y), over Δx (the change in x). In other words, rise over run. To solve for Δ, you'd have to subtract the second output (y²) from the first (y¹). There are really no rules as to which has to be minuend and the subtrahend, so I chose to subtract (-1,6) from (4,3) for the first problem.
y¹-y² Δy 3-6 -3
------ or ---- so ------- = ----- The slope is represented by -3/5x
x¹-x² Δx 4-(-1) 5
__________________________________________________________
For the second, substitute the values again (make sure you keep the xs and ys together and in the right order, otherwise your answer will be incorrect). Remember that subtracting a negative number is basically just adding a positive number. That's why the slope is 18/32 and not 4/26.
11-(-7) 18
--------- = -------
29-(-3) 32
___________________________________________________________
For number three, they give you a point, then tell you the y-intercept. With that in mind, also know the second point is (0,17), because the x value at the y-intercept is always 0.
7-17 -10
------ = ------- The slope is -10/11x
11-0 11
___________________________________________________________
4-4 0
------ = --------
6-(-9) 15
Because there is no Δy, but there is Δx, we know that the line for y will be straight and shows no change- it will always be at 4. That said, the line will be horizontal.
I hope this helps. I know this is very confusing at first, but with practice, you'll eventually get the hang of it. I've tried to explain the rules to the best of my ability- let me know if there's anything you don't understand or need more help with.

Step-by-step explanation:
958.990 is the Round off to the nearest hundred.
What is rounding a number to some specific place?Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
The digit 5 acts as a limit.
If the digit on right is 5, and after it there is only zeros or no value, then we round up (increase by 1, as we did in 347500 -> 34800 ) (Well there are many detailed rules of rounding)

I am having trouble understanding this: Sam bought 86 pounds of flour for his bakery. Every day he used the same amount of flour to make bakery items. After 10 days, Sam was left with 25.2 pounds of flour. On average, how many pounds of flour did Sam use each day?
A. 3.01 Pounds
B. 5.65 Pounds
C. 6.08 Pounds
D. 11.12 Pounds
Please also include an explanation. Thanks!
Answer:
the average amount of flour used each day=6.08 pounds
Step-by-step explanation:
Sam bought 86 pounds of flour for his bakery.
Every day he used the same amount of flour to make bakery items.
After 10 days, Sam was left with 25.2 pounds of flour.
Now we are asked to find the average pounds of flour that Sam used each day.
Total amount of flour used=86-25.2=60.8 pounds.
As he used the flour equal amount each day for 10 days.
So, the average flour used each day=
amount of flour used/ number of days=60.8/10=6.08.
the average amount of flour used each day=6.08 pounds
Answer:
C
Step-by-step explanation:
So since Sam have 25.2 leftover pounds of flour, we can subtract that from 86, knowing that will be left over in the end. Next, we divide the number left. 86 - 25.2 = 60.8
Finally, divide that by 10, since there are 10 days.
We end up with 6.08 pounds.

Bob and Carl each rented the same kind of moving truck from EZ Move. There was a flat rental fee plus a charge per mile that the truck was driven. Bob's cost for his truck was $112.96 for 138 miles. Carl's cost for his truck was $142.78 for 209 miles. Which equation can be used to represent the cost of the rental truck? Round to the nearest hundredth if necessary.
Answer:
Total cost= 55 + 0.42*x
x= miles driven
Step-by-step explanation:
Giving the following information:
Bob's cost for his truck was $112.96 for 138 miles.
Carl's cost for his truck was $142.78 for 209 miles.
To calculate the fixed cost and variable cost per mile, we need to use the high-low method:
Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)
Variable cost per unit= (142.78 - 112.96) / (209 - 138)
Variable cost per unit= $0.42 per mile
Fixed costs= Highest activity cost - (Variable cost per unit * HAU)
Fixed costs= 142.78 - (0.42*209)
Fixed costs= $55
Fixed costs= LAC - (Variable cost per unit* LAU)
Fixed costs= 112.96 - (0.42*138)
Fixed costs= $55
Finally, the cost equation:
Total cost= 55 + 0.42*x
x= miles driven

In the figure below, points J, K, and L are the midpoints of the sides of AXYZ.
Suppose JK=38, X2=96, and YX=56.
Find the following lengths.
Answer:
28 ; 76 ; 38
Step-by-step explanation:
KL = [tex]\frac{XY}{2}[/tex] = [tex]\frac{56}{2}[/tex] = 28 units
YZ = 2 × JK = 38 × 2 = 76 units
LZ = 76/2 = 38 units
The lengths are: KL = 28 units, YZ = 76 units and LZ= 38 units.
What is Mid point theorem?The line segment in a triangle connecting the midpoint of two sides of the triangle is said to be parallel to its third side and is also half the length of the third side, according to the midpoint theorem.
Given:
J, K, and L are the midpoints of the sides of ΔXYZ.
JK=38, X2=96, and YX=56.
Now, using Mid point theorem
JK= 1/2 YZ
38 = 1/2 YZ
YZ= 2 x 38
YZ = 76 units.
and, KL= 1/2 YX
KL = 1/2(56)
KL= 28
LZ = 1/2 (YZ)
LZ = 1/2(76)
LZ = 38 units

An insurance company charges Ted $1400 per year for insurance on his home. The company has predicted that there is a 10% chance that Ted will make a claim on the policy of $5000. Create a probability distribution and determine what the insurance company can expect to make on this policy, on average?
Answer:
The insurance company can expect to make $900 on the policy
Step-by-step explanation:
The given parameters are;
The amount Ted pays per year for insurance on his home = $1,400
The value of the insurance policy = $5000
The chance that Ted will make a claim on the policy = 10%
The expected value is given as follows
Incidence [tex]{}[/tex] Probability Value v × p
A claim is made [tex]{}[/tex] 0.1 $5,000 - $1,400 = -$3,600 -$360
No claim [tex]{}[/tex] 0.9 [tex]{}[/tex] $1,400 $1260
Expected value is $1,260 - $360 = $900
The value the insurance company can be expected to make on average on the policy is $900

Working together, Candice and Ximena painted a fence in 8 hours. Last year, Ximena painted the fence by herself. The year before, Candice painted it by herself, but took 12 hours less than Ximena took. How long did Candice and Ximena take, when each was painting alone?
Answer: Time taken by Ximena to paint the fence alone = 24 hours
Time taken by Candice to paint the fence alone = 12 hours
Step-by-step explanation:
Let x= Time taken by Ximena to paint the fence alone .
Time taken by Candice to paint the fence alone = x-12
As per given , we have
[tex]\dfrac{1}{x}+\dfrac{1}{x-12}=\dfrac{1}{8}\\\\\Rightarrow\ \dfrac{x-12+x}{x(x-12)}=\dfrac{1}{8}\\\\\Rightarrow\ 8(2x-12)=x^2-12x\\\\\Rightarrow\ 16x-96=x^2-12x\\\\\Rightarrow\ x^2-12x-16x+96=0\\\\\Rightarrow\ x^2-28x+96=0\\\\\Rightarrow\ x^2-4x-24x+96=0\\\\\Rightarrow\ x(x-4)-24(x-4)=0\\\\\Rightarrow\ (x-4)(x-24)=0\\\\\Rightarrow x=4, 24[/tex]
if x= 4
Time taken by Ximena = 4 hours
Time taken by Candice = 4-12 hours =-8 hours which is not possible. (time cannot be negative)
Therefore, x= 24
Such that
Time taken by Ximena to paint the fence alone = 24 hours
Time taken by Candice to paint the fence alone = 24-12=12 hours

What is the average rate of change of the function f(x) = 2x2 + x + 5 over the interval −2 ≤ x ≤ 2?
A. −4 B. −1 C. 1 D. 4
Answer:
d
Step-by-step explanation:
The average rate of change the function f(x) = 2x² + x + 5 is 1.
So, Option C is correct.
The average rate of change
The average rate of change in a function is the rate at which one value changes with respect to another value.
Given function: [tex]f(x)=2x^2+x+5[/tex] on interval [tex][-2,2][/tex]
Therefore,
Average rate of change = [tex]\frac{f(2)-f(-2)}{2-(-2)}[/tex]
[tex]f(2)=2(2)^2+2+5\\f(2)=15\\f(-2)=2(-2)^2-2+5\\f(2)=11[/tex]
Substitute the values,
Average rate [tex]=\frac{15-11}{2+2}[/tex]
Average rate [tex]=\frac{4}{4}[/tex]
Average rate [tex]=1[/tex]
So, the average rate of change is [tex]1[/tex]
Option C is correct.
