Y=x would be the lesser relationship i believe. when Y=x is graphed the slope has a lesser rise over run output. AKA, the slope is less steep and takes longer to reach higher on the graph as to compared relationship A

Eric plays basketball and volleyball for a total of 95 minutes every day. He plays basketball for 25 minutes longer than he play
ioda

Answer:

Part A:

x+y= 95

x = y+25

Part B : 35 minutes

Part C : No

Step-by-step explanation:

  • Part A :

Eric plays basketball and volleyball for a total of 95 minutes every day

x+y= 95

Where:

x =the number of minutes Eric plays basketball

y= the number of minutes he plays volleyball  

He plays basketball for 25 minutes longer than he plays volleyball.

x = y+25

System:

x+y= 95

x = y+25

  • Part B:

Replacing x=y+25 on the first equation:

(y+25) + y =95

Solving for Y

y+25+y =95

25+2y=95

2y=95-25

2y=70

y = 70/2

y = 35 minutes

Part C : No

if x = 35

x+y= 95

35+y =95

y= 95-35

y = 60 minutes

Replacing y=60 on the other equation:

x = y+25

35 = 60+25

35 ≠85

What is the result of subtracting the second equation from the first? \begin{aligned} x-3y &= 6 \\\\ -8x-y &= 6 \end{ali
Mila [183]

Answer:

Therefore the required result is 9x-2y =0.

Step-by-step explanation:

Given equation are

x-3y =6.....(1)

-8x-y=6 .....(2)

Subtracting equation (2) from (1)

 x  -  3y = 6

-8x  -  y=  6

+     +      -                 [ The sign of equation (2)  will be change in case of          

_________               subtraction and in case of plus the signs remains same ]

(x+8x)-3y+y=6-6   [ adding the like terms]

⇒9x-2y =0

Therefore the required result is 9x-2y =0.

Two groups of students order burritos and tacos at a local restaurant. One order of 3 burritos and 4 tacos coast 11.33. The othe
makkiz [27]
3B + 4T = 11.33 9B + 5T = 23.56 Solve by elimination: Multiply the first equation by -3 to get -9B where the 3B is so that it will cancel with the 9B when the equations are added. -9B - 12T = -33.99 9B + 5T = 23.56 ------------------ -7T = -10.43 T = $1.49 Substitute in 3B + 4T = 11.33 3B + 4(1.49) = 11.33 3B + 5.96 = 11.33 3B = 5.37 B = $1.79 A taco costs $1.49 and a burrito costs $1.79. Therefore 5 burritos and 7 tacos will cost 5B + 7T = 5($1.79) + 7($1.49) = $19.38

-2x – 4 &lt; 3x + 21<br> Solve the inequality
I am Lyosha [343]

Isolate the x. Subtract 3x from both sides, and add 4 to both sides

-2x (-3x) - 4 (+4) < 3x (-3x) + 21 (+4)

-2x - 3x < 21 + 4

Simplify. Combine like terms

-5x < 25

Isolate the x. Divide -5 from both sides (remember to flip the sign).

-5x/-5 < 25/-5

x > 25/-5

x > -5

x > -5 is your answer

hope this helps
