Rate = distance / time.

Distance= 9/10

Time = 1/10

Rate = 9/10 divided by 1/10 which is 9.

Answer:

110,000 – 330,000 lbs

Step-by-step explanation:

I GOT CHU

[tex]f(x) = \frac{1}{3}x - 4 \\ [/tex]

[tex]y = \frac{1}{3}x - 4 \\ [/tex]

Subtract the sides of the equation plus 4

[tex]y + 4 = \frac{1}{3}x \\ [/tex]

Multiply the sides of the equation by 3

[tex]3(y + 4) = x[/tex]

[tex]3y + 12 = x[/tex]

So ;

[tex] {f}^{ - 1}(x) = 3x + 12 [/tex]

sorry if im wrong

Answer:

I am pretty sure it is 72, sorry if i'm wrong:)

Step-by-step explanation:

[tex](2x - 9) + (3x - 6) = 110[/tex]

[tex]2x + 3x - 9 - 6 = 110[/tex]

[tex]5x - 15 = 110[/tex]

Plus sides 15

[tex]5x - 15 + 15 = 110 + 15[/tex]

[tex]5x = 125[/tex]

Divided sides by 5

[tex] \frac{5}{5}x = \frac{125}{5} \\ [/tex]

[tex]x = 25[/tex]

Thus ;

A = 2 ( 25 ) - 9°

A = 50° - 9°

A = 41°

_________________________________

B = 3 ( 25 ) - 6

B = 75° - 6°

B = 69°

_________________________________

C + 110° = 180°

because it is a straight line.

Subtract sides 110°

C + 110° - 110° = 180° - 110°

C = 70°

[tex]\Large \boxed{\sf \bf 2x^2-12x+10}[/tex]

Step-by-step explanation:

Hello,

As 1 and 5 are roots we can write, with a real number, the quadratic equation as

a(x-1)(x-5)

and as the leading coefficient is 2 then a = 2

It comes

[tex]2(x-1)(x-5)=2(x^2-6x+5)=2x^2-12x+10[/tex]

Thanks

The quadratic equation will be 2x²-12x+1=0.

Quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that the roots of the quadratic equation are 1 and 5 and the leading coefficient is 2.

The equation will be written as,

Quadratic equation = 2( x - 1 ) ( x - 1 )

Quadratic equation = 2 ( x² + 4x - 5)

Quadratic equation  = 2x² + 8x - 10

Therefore, the quadratic equation will be 2x²-12x+1=0.

Step-by-step explanation:

The answer (y intercept) occurs when x = 0

The answer is -2

-5y = 10

y = 10/-5

y = - 2

Answer:

(0, -2)

Step-by-step explanation:

to find the y-intercept u need to put it into the slope intercept form.

first you move the X to the other side of the equation and get -5y = -2x + 10

then u divide -5 on each side and get y = 2/5 x -2

in y=mx+b and,b is the y intercept

so the y intercept is -2

Answer:

k=45

Step-by-step explanation:

Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that [tex]45+2k+k=180[/tex]. 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have  [tex]45+3k=180[/tex]. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides [tex]45-45+3k=180 -45 \\3k=135[/tex] as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.

Answer:

1. 30(8.75) + 11t = 400

2. 12.5 hours

Step-by-step explanation:

1. What is given is you work for 30 hours per week at a gas station for $8.75 an hour. You also work as a landscaper for $11 an hour. You want to a make a total of $400 per week.

30 hours and $8.75 an hour would be equivalent to 30(8.75)

We don’t know how many hours you work as a landscaper but you earn $11 an hour, which is equivalent to 11t

Finally, you want to earn a total of $400 a week, which means the sum equals 400

30(8.75) + 11t = 400

2. 30(8.75) = 262.5

400 - 262.5 = 137.5

137.5 / 11 = 12.5
