Answer:
(-1, 3)
Step-by-step explanation:
Only the first question is complete.
You want to solve ...
2x +y = 1
3x -y = -6
You can add these two equations to get ...
5x = -5
x = -1 . . . . . divide by 5
This matches the first choice: (-1, 3).
Answer:
A: (-1,3) is the correct answer to the problem.

Answer:
45 minutes
Step-by-step explanation:
We want to know how long it takes to an airplane to fly a distance of 375 miles, if the speed of the airplane is 500 miles per hour.
For this, we should divide the distance/speed to get the time that the plane needs.
T = 375mi/(500mi/h) = 0.75 hours
The plane needs 0.75 hours or 0.75*60 = 45 minutes to fly that distance.

PLEASE HELP! I’m so confused and i’ve already tried and gotten wrong.
30 points
Answer:
if there was a 15% discount, then you paid 75% of the original price. Since we don't know the orginal price, we will assign it the variable x. Change 75% to a decimal. The equation would be:
.75x = 208.25 To get the variable by itself, divide each side by .75
.75x/.75= 208.25/.75
x = 277.6
The original price of the suit was $277.6

Convert 10 mL/sec to L/min
Step-by-step explanation:
1000 mL = 1 L
10 mL = 1/1000 × 10 = 0.01 L/sec
60 sec = 1 min
1 sec = 1/60 min
0.01 L/sec
= 0.01 L × 60
= 0.6 L/min
10 mL/sec = 0.6 L/min
on a time Find the midpoint of segment GL if G (- 2, 46) and L (4, 10). Write your anwer in coordinate pair form (x, y)
Answer:
(1, 28 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]
here (x₁, y₁ ) = G(- 2, 46) and (x₂, y₂ ) = L(4, 10), thus
midpoint = ([tex]\frac{-2+4}{2}[/tex] , [tex]\frac{46+10}{2}[/tex] ) = ([tex]\frac{2}{2}[/tex] , [tex]\frac{56}2}[/tex] ) = (1, 28 )
Ann Clair and josh collect sticker one week Ann collects 7 more sticker then josh josh collect twice as many stickers as Claire. If they collect a total of 157 stickers how many sticker did each collect
Answer:
Ann: 67Clair: 30Josh: 60Step-by-step explanation:
If we let A, C, and J represent the number of stickers collected by Ann, Clair, and Josh. respectively, then we have the relations ...
A = J +7
J = 2C
A + C + J = 157
__
Substituting the first equation into the last, we have ...
J +7 + C + J = 157
C +2J = 150 . . . . . . . collect terms, subtract 7
Substituting the second equation into this one, we have ...
C +2(2C) = 150
C = 150/5 = 30 . . . . divide by the coefficient of C
J = 2·30 = 60
A = 60 +7 = 67
Ann collected 67 stickers, Clair collected 30, and Josh collected 60 stickers.
Answer:
Ann has 67
Josh has 60
Claire has 30

given b(x) = |x+4| , what is b(-10)
Answer:
6
Step-by-step explanation:
|-10+4| = |-6|= 6
inside the | | the equation is done normally. that's why it has a negative at first. then, once getting rid of the bars, you change the number to a positive
Answer:
[tex]\boxed {\tt b(-10)=6}[/tex]
Step-by-step explanation:
We are given the function:
[tex]b(x)= \mid x+4 \mid[/tex]
We want to find b(-10). Therefore, we must plug -10 in for each x.
[tex]b(-10)= \mid -10+4 \mid[/tex]
Solve inside of the absolute value symbol. Add 4 to -10 ⇒ -10+4= -6
[tex]b(-10)= \mid -6 \mid[/tex]
Absolute value represents how far away a number is from 0. It is always positive.
-6 is 6 away from 0. Therefore, the absolute value of -6 is 6.
[tex]b(-10)= 6[/tex]
b(-10) is equal to 6.

Records show that Oliver is typically 10–30 minutes late for his shift at work. The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve. John and Oliver are working a shift that starts at the same time. John always arrives 8 minutes late. What percentage of the time does Oliver arrive within 10 minutes of John's arrival time? O 26.7% O 33.3% 2 O 40% O 50%
Answer:
40%
Step-by-step explanation:
10 minutes late would mean 18 minutes late on the graph. The graph goes from 10-30 which creates a difference of 20. 8 divided by 20 equals 40 percent.
40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.
Given that,
Oliver is typically 10–30 minutes late for his shift at work.
The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve.
John and Oliver are working a shift that starts at the same time. John always arrives 8 minutes late.
We have to determine,
What percentage of the time does Oliver arrive within 10 minutes of John's arrival time?
According to the question,
Oliver is typically 10–30 minutes late for his shift at work.
John and Oliver are working a shift that starts at the same time.
John always arrives 8 minutes late.
From the complete information, the probability distribution will be:
[tex]= \dfrac{1}{b-a}\\\\= \dfrac{1}{30-10}\\\\= \dfrac{1}{20}[/tex]
Here, John always arrives 8 minutes late.
Therefore,
The percentage of the time that Oliver arrives within 10 minutes of John's arrival time is,
[tex]\rm = 8 \times \dfrac{1}{20}\\\\= \dfrac{2}{5}\\\\= 0.4 \times 100 \\\\= 40 \ Percent[/tex]
Hence, 40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.

Action video rents dvds and video games to its customers. The cost to rent d, DVD movies, is $3.50 each and the cost to rent r, video games, is $2.50 each. Which of these represents the possible number of DVDs that could be rented for no more that $20?
Answer:
d = 5.71
Step-by-step explanation:
Let
Quantity of DVD movies = d
Quantity of Video games = r
Price of DVD movies = $3.50
Price of video games = $2.50
Total budget plan for DVD movies= $20
Which of these represents the possible number of DVDs that could be rented for no more that $20
Price of DVD movies × Quantity of DVD movies = $20
$3.50 × d = $20
3.50d = 20
Divide both sides by 3.50
d = 20/3.50
= 5.71
