Answer:

(8, -5); x=8; y=-5

Step-by-step explanation:

i'll be solving via substitution

2x+3y=1; y=-2x+11

2x + 3(-2x +11) = 1

2x -6x +33 = 1

-4x = -32

x = 8

2(8) + 3y = 1

16 + 3y = 1

3y = -15

y = -5

(8, -5)

Check:

-5 = -2(8) + 11

-5 = -16 + 11

-5 = -5

Subtract the spent money to rent cost:

27-5.75=21.25

Divide the answer to the cost of each game:

21.25/4.25=5

he played 5 times.

Answer:

0.94

because 5 《 x 《 10

=> the average rate of change of the function is

[tex] \frac{0.2(1.4) {}^{10} - 0.2(1.4) {}^{5} }{10 - 5} = 0.94[/tex]

Answer: x=1 and y=3

Step-by-step explanation: hope this help

The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The linear equations are given below.

x + 5y = 16        ...1

x + 3y = 10        ...2

Subtract equation 2 from equation 1, then we have

x + 5y - x - 3y = 16 - 10

2y = 6

y = 3

Then the value of the variable 'x' will be given as,

x + 5(3) = 16

x + 15 = 16

x = 1

The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).

Answer:

3x − 3 = 0

3(x − 1) = 0

x = 3 /3  = 1

[tex]7x + 4 = 4x + 7[/tex]

[tex]7x - 4x = 7 - 4 \\ 3x = 3 \\ x = \frac{3}{3} \longrightarrow \frac{ \cancel{3}}{ \cancel{3}} = 1 \\ x = 1[/tex]

[tex]7(1) + 4 = 4(1) + 7 \\ 7 + 4 = 4 + 7 \\ 11 = 11 \longrightarrow \sf{true} \: \: \green{ \checkmark}[/tex]

Step-by-step explanation:

If the missile was going 900 mph and we are trying to find the horizontal velocity

This could be 3.88, and rounding it to the nearest hundredth would be 3.90 miles per minute

Answer:

1.45 miles per minute

Step-by-step explanation:

The question asked it to be presented in miles per minute so divide 1000 by 60 which will give us 50/3. We then multiply that with cos(85) which will give us the final answer of 1.45.

Answer:

y = -3x + 10

Step-by-step explanation:

6x+2y=20

First, you want to subtract 6x from both sides.

2y=-6x+20

Now, you want to divide by 2 on both sides because you want to get y by itself.

y = -3x + 10

Answer:

Y = -3x + 10

Step-by-step explanation:

Subtract the 6x from both sides to get y by itself

You would have 2y=-6x+20

Divide everything by 2 for the correct formula format

You would have y=-3x+10

Answer:

x = 2

Step-by-step explanation:

[tex]\frac{3x-5}{6} = \frac{1}{6} \\[/tex]

In order to solve this, you must get the denominator off of the left-hand side of the equation, by multiplying 6 on each side, in order to get the denominators to cancel. This leaves you with:

[tex]3x-5 = 6/6\\3x-5 = 1[/tex]

Then, you add 5 to each side.

[tex]3x = 6[/tex]

Divide by 3, to get x by itself.

[tex]x = 2[/tex]

Which gets us to our final answer of x = 2.

Then, you can plug x back into the equation just to double-check yourself:

[tex]\frac{3(2)-5}{6} = \frac{1}{6} \\\\\frac{6-5}{6} = \frac{1}{6}\\\\\frac{1}{6} = \frac{1}{6}[/tex]

I hope that this helped you understand to concept a little better. Good luck.
