If x = -3,
then y might equal -6
If y = -20,
then x might equal -13
Step-by-step explanation:
I have used a graph to estimate these answers. See image. If you are learning how to find the line of best fit for a data set, you might be expected to do those calculations, depending on the level of your math class. Many upper level math classes would use technology to find a line of best fit.
See image to see the data set given on an xy-axis in red. The circled areas are where the estimated numbers would lie, where
x = -3 (in blue) and where
y = -20 (in green)
The directions say estimate, so a graph is a good justification for several answers in the general area.

Round
your answer to the nearest hundredth.
Answers
Answer:
21.1%
Step-by-step explanation:
(25 - 24.3) / 1.2 = 0.5833 z score = 78.9%
You need the percent that spend more than 25 hrs per week, so 100 - 78.9 = 21.1%

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (5, 29) ← 2 ordered pairs from the table

Find the number of hours worked from 7:34 A.M.
to 11:48 A.M., assuming pay is for full quarter-
hours.
Answers
Answer:
3 hours
Step-by-step explanation:
If pay is for full quarter hours, then the worker won't get paid for work intervals of less than 15 minutes.
Subtract 7:34 from 11:48: we get 3:14 hours. Because the 14 minutes is less than the 15 minutes of a full quarter hour, the worker won't get paid for those 14 minutes.
So the 'number of hours worked' is 3 hours.
Note that 3:14 would be 3 hours 14 minutes.

Yet another path you could take is to use Pascal's Triangle. Locate the row that starts with 1,6,... and then locate the second to last item. That value in the triangle is 6.
A real world interpretation is to consider having 6 people and you are selecting 5 of them to form a group where order doesn't matter. How many ways are there to do this? Well there are 6 such ways because there are 6 ways to leave someone out of the group.

Cost to cross the bridge(one-way): Truck (2 or 3 axles): $3.00 Truck (4 or 5 axles): $6.25 Truck (6 or more axles): $10.00. One morning, 3 trucks, each with 5 axles, and 1 truck with 8 axles, crossed the bridge in one direction. write a math problem and solve it to answer. HOW MUCH WAS THE TOLL FOR THE CROSSING OF THE BRIDGE.
Answers
Truck (2 or 3 axles): $3.00
Truck (4 or 5 axles): $6.25
Truck (6 or more axles): $10.00
Day1= 3 trucks with 5 axles and 1 truck with 8 axles passed the bridge
What we need to find:
Part a: an expression that represents the first passing of the 4 trucks and
a solution to the the first expression
Part b: a modification of first expression that includes the return passing of the 4 trucks and a solution for the trucks passing both times.
Part a:
3(6.25)+1(10.00)
3(6.25)+1(10.00)=$28.75
Part b:
2[3(6.25)+1(10.00)]
2[3(6.25)+1(10.00)]=2[28.75]=$57.50

Find the solution to the following system using substitution or elimination:
y = -x + 10
y= 7x+ 2
O A. (1, - )
O B. (1,9)
O C. (,1)
O D. (9,65)
Answers
Answer:
B
Step-by-step explanation:
y = - x + 10 → (1)
y = 7x + 2 → (2)
Substitute y = 7x + 2 into (1)
7x + 2 = - x + 10 ( add x to both sides )
8x + 2 = 10 ( subtract 2 from both sides )
8x = 8 ( divide both sides by 8 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (2)
y = 7(1) + 2 = 7 + 2 = 9
solution is (1, 9 ) → B

25 = 1.50x
16.666... = x
