Determine which point is the solution to the given system.

Mathematics
1 answer:
KatRina [158]4 years ago

Answer:

D

Step-by-step explanation:

We equate both the y's and solve for x algebraically:

-\frac{4}{7}x+16=-\frac{2}{7}x+12\\16-12=-\frac{2}{7}x+\frac{4}{7}x\\4=\frac{2}{7}x\\x=\frac{4}{\frac{2}{7}}\\x=14

Now taking the value x= 14 and putting it in the 1st equation would give us y:

y=-\frac{4}{7}x+16\\y=-\frac{4}{7}(14)+16\\y=8

Hence the solution is (14,8), answer is D

Brianna has a container with a volume of 1.5 L she estimates the volume to be 2.1 m what is the percent error
Anuta_ua [19.1K]
<h3>Answer: 40%</h3>

===================================================

Work Shown:

Subtract the values to get 2.1-1.5 = 0.6

Brianna is off by 0.6 liters

Divide that error by the true value 1.5 to get 0.6/1.5 = 0.40

Then move the decimal point 2 spots to the right to arrive at 40%

Therefore, the percent error is 40%

------------------

The formula you can apply is:

P = \frac{|G-T|}{T}*100\%

where

P = percent error

G = guess value (in this case it is 2.1)

T = true value (which is 1.5 in this case)

If we were to apply the formula, then we get:

P = \frac{|G-T|}{T}*100\%\\\\P = \frac{|2.1-1.5|}{1.5}*100\%\\\\P = \frac{|0.6|}{1.5}*100\%\\\\P = \frac{0.6}{1.5}*100\%\\\\P = 0.40*100\%\\\\P = 40\%\\\\

. On a recent business trip, a salesman traveled 52 miles the first hour, 64 miles the second hour and 49 miles the third hour.
igomit [66]

Remark

The average is found by adding the total miles and dividing by the total number of hours.

Average

total distance = 52 + 64 + 49

Total distance = 165 miles

Total time = 1 + 1 + 1 = 3 hours.

Average = total distance/ total time

Average = 165  /   3 = 55 miles per hour.
