1-4x

Step-by-step explanation:

Step-by-step explanation:

1 - ((9*t) - (9*-2) = ( 4*t) - (4*-15)

1 - 9t + 18 = 4t + 60

- 9t - 4t = 60 - 1 - 18

-13t = 40

t = 40/-13

[tex]\frac{3}{1}[/tex]Answer:

Step-by-step explanation:

3x-y = 2

2x+y =4

put them into slope intercept form

y=3x-2

y=-2x+4

Now, you can either graph it or use substitution

3x-2 = -2x+4

+2x +2x

5x -2 = 4

+2 +2

5x = 6

5x/5 = 6/5

x = 6/5

3x -2 = y

3(6/5) -2 = y

3 x 6 / 1 x 5 = 18/5

3 3/5 -2 = 1 3/5

Let me know if it's wrong.

Hey there! I'm happy to help!

Here's how to find the distance between any two points.

Subtract the x values.

5-(-1)=5+1=6

Square that.

6²=36

Subtract the y values.

0-4=-4

Square that.

-4²=16

Add the two numbers you got.

36+16=52

And square root it.

√52≈7.2.

Have a wonderful day! :D

Answer: No Solution

Step-by-step explanation:

When there are absolute values on both sides, you simply just get rid off the signs. (Normally, it results in positive and negative on the other side)

SOLVE:

Given

|-9-7x|=|23-7x|

No absolute value sign

-9-7x=23-7x

Add 7x on both sides

-9=23

ANSWER:

This is no solution, because -9≠23

The minimum amount of money that the operator earns when n people ride the bus is $10.5 and the maximum amount of money that the operator earns when n people ride the bus is $35.

A small bus charges $3.50 per person for a ride from the train station to a concert.

The maximum capacity of the bus to carry the passengers is 10.

The minimum capacity of the bus to carry the passengers is 3.

Function B gives the amount of money that the bus operator earns when n people ride the bus.

Thus the value of 'n' is restricted between 3 to 10.

Therefore,

In general, the amount of money that the operator earns when n people ride the bus is given by the expression.

[tex]\rm{Amount}= \$3.5n[/tex]

The above amount can have minimum and maximum values.

Thus, the minimum amount of money that the operator earns when n people ride the bus is $10.5 and the maximum amount of money that the operator earns when n people ride the bus is $35.

Answer:

k = 16

Step-by-step explanation:

Isolate the variable, k. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and =

Parenthesis

Exponents (& Roots)

Subtract 67 from both sides of the equation:

k + 67 = 83

k + 67 (-67) = 83 (-67)

k = 83 - 67

k = 16

16 is your answer for k.

Answer:

40

Step-by-step explanation:

This is the answer because:

1) Whenever you are multiplying negative integers, remeber these rules:

Negative x Positive = Negative

Positive x Negative = Negative

Negative x Negative = Positive

Positive x Positive = Positive

2) Since -5 and -8 are both positive numbers, the answer will be a positive product:

5 x 8 = 40

Therefore, the answer is 40.

Answer: [tex]\frac{1}{\sqrt[3]{x} }[/tex]

Step-by-step explanation:

Since the base of the exponents are the same, we can go ahead and subtract the exponents.

[tex]\frac{x^{\frac{5}{6}} }{x^{\frac{7}{6} }}[/tex]               [subtract exponents]

[tex]x^{-\frac{2}{6} }[/tex]             [simplify exponent]

[tex]x^{-\frac{1}{3}}[/tex]             [write in radical form]

[tex]\frac{1}{\sqrt[3]{x} }[/tex]

Answer:

13.

Step-by-step explanation:

Cross multiply:  [tex]\frac{3x-15}{2}=\frac{2x+10}{3}[/tex]

Remove the brackets: 3(3x-15) = 2(2x+10)

Move the terms: 9x-45 = 4x+20

Collect like terms and calculate: 9x-4x=20+45

Divide both sides: 5x = 65

Answer:

Total loss in three days = $393.75

Step-by-step explanation:

Given:

Loss amount = [-3/8] of normal profit

Normal profit per day = $350

Find:

Total loss in three days

Computation:

Total loss in three days = 3 [Normal profit per day][Loss amount]

Total loss in three days = 3 [350][3/8]

Total loss in three days = 3[131.25]

Total loss in three days = $393.75

Answer:

9.25

Step-by-step explanation:

5(0.3) = 1.5

20-1.5=18.5

18.5÷2=9.25

Answer:

Step-by-step explanation:

5x + 2y = 20

when x = 0.3 we have

5(0.3) + 2y = 20

1.5 + 2y = 20

Using the subtraction property subtract 1.5 from both sides of the equation

That's

1.5 - 1.5 + 2y = 20 - 1.5

2y = 18.5

Divide both sides by 2

[tex] \frac{2y}{2} = \frac{18.5}{2} [/tex]

We have the final answer as

Answer:

[tex]f=\frac{9c}{5}+32[/tex]

Step-by-step explanation:

[tex]c=\frac{5\left(f-32\right)}{9}[/tex]

Switch sides:

[tex]\frac{5\left(f-32\right)}{9}=c[/tex]

Multiply both sides by 9:

[tex]\frac{9\times5\left(f-32\right)}{9}=9c[/tex]

[tex]5\left(f-32\right)=9c[/tex]

Divide both sides by 5:

[tex]\frac{5\left(f-32\right)}{5}=\frac{9c}{5}[/tex]

[tex]f-32=\frac{9c}{5}[/tex]

Add 32 to both sides:

[tex]f-32+32=\frac{9c}{5}+32[/tex]

[tex]f=\frac{9c}{5}+32[/tex]

Step-by-step explanation:

Here we have the formula for the area of a triangle: [tex]A = \frac{1}{2}bh[/tex]. Our goal is to isolate h on one side of the equation.

To do this, let’s treat the rest of the equation as if there were no variables.

Multiply both sides by 2:

[tex]2a = bh[/tex]

Divide both sides by [tex]b[/tex]:

[tex]\frac{2a}{b} = h[/tex]
