2) Slope --1, y-intercept = 1

Answer:

20 degrees

all angles must be equal and all angles add up to 60 degrees ;)

Answer: 9

Step-by-step explanation:

Two negatives make a positive. So the expression 8-(-1) is equal to 9, because the two subtraction signs the equation create an addition sign, and the equation becomes 8 + 1.

Therefore, 9 has the same value as 8-(-1).

Answer:

3.5 hours

Step-by-step explanation:

If the water goes down by 0.4 feet every hour

we can add 0.4 + 0.4 + 0.4 (0.4 x 3) and get 1.2 and 1.4 - 1.2 - 0.2

And we also know that half of 0.4 is 02 so we can add 0.2 to 1.2 in order to get our desired answer. Which is 1.4 So now let's add what we multipleied by

3 + 1/2 = 3.5

Answer:

y = 6/5x -5

Step-by-step explanation:

Points are (5,1) (0,-5)

-5 - 1/ 0-5 = 6/5 slope

y-y1= m(x-x1)

y- 1 = 6/5(x-5)

y -1 = 6/5X - 6

y = 6/5X -5

Answer:[tex]\frac{-5}{4}, \frac{3}{4}[/tex]

Step-by-step explanation:

Given

[tex]\theta[/tex] is in the third quadrant and

[tex]\Rightarrow \cos \theta=\frac{-3}{5}[/tex]

tan and cot is positive in the third quadrant and the rest are negative

using identity

[tex]\sin^2 \theta+\cos^2 \theta=1\\\Rightarrow \sin \theta=-\sqrt{1-\cos^2 \theta}\\\Rightarrow \sin \theta =-\sqrt{1-(-\frac{3}{5}^2)}\\\Rightarrow \sin \theta =-\frac{4}{5}\\\Rightarrow\text{cosec} \theta=-\frac{5}{4}\\\Rightarrow \cot \theta=\frac{\cos \theta}{\sin \theta}=\frac{\frac{-3}{5}}{\frac{-4}{5}}=\frac{3}{4}[/tex]

Answer:

angle ADB = 41 degrees

angle ABD = 90 degrees

angle AFE = 70 degrees

angle ACE = 31 degrees

Step-by-step explanation:

angle ADB = 41 degrees because minor arc AB = 82 degrees and it's inscribed angle is 1/2 of it's arc.

angle ABD = 90 degrees because arc AED = 180 degrees and inscribed angles are equal to 1/2 of the arc.

arc ABD = 180

arc ABE = arc ABD + 70 degrees = 250 degrees

minor arc AE = 360 degrees-250 degrees = 110 degrees

angle AFE = 1/2 (250-110) = 70 degrees

angle ACE = 1/2(110-48) = 31 degrees

Answer:

Number of coins that are not nickels = 55 coins

66 = 55 + n

number of nickels in the​ jar = 11

Step-by-step explanation:

Pennies = 17

Dimes = 12

Quarters = 26

Nickels = n

Total coins = 66

How many of the coins are not​ nickels?

= Pennies + Dimes + Quarters

= 17 + 12 + 26

= 55 coins

Number of coins that are not nickels = 55 coins

what equation could you use to find​ n?

Total coins = Pennies + Dimes + Quarters + nickels

66 = 17 + 12 + 26 + n

66 = 55 + n

n = 66 - 55

n = 11

number of nickels in the​ jar = 11

Answer:

0.17 over 1

Step-by-step explanation:

So, first we have to find a comman factor. between 255, and 15 the GCF is 15, so 255 ÷ 15 = 17      So that is:

            255 ÷ 15 = 17                

Now we move the decimal into place so its $0.17 becaue 0.17 x 15 = 2.55

Answer

70%

Step-by-step explanation:

Answer:

X = 18.

Step-by-step explanation:

The median = 11 so the mean is also 11 (given).

So mean  = 11 = (7 + 8 + 11 + 11 + X) / 5

(37 + x)/ 5 = 11

x + 37 = 55

x = 55 - 37 = 18.

Answer:

see explanation

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 3x - 2 ( add 2 to both sides )

y + 2 = 3x ( divide both sides by 3 )

[tex]\frac{y+2}{3}[/tex] = x

change y back into terms of x with x = [tex]f^{-1}[/tex] (x)

[tex]f^{-1}[/tex] (x) = [tex]\frac{x+2}{3}[/tex]

To evaluate [tex]f^{-1}[/tex] (13) substitute x = 13 into [tex]f^{-1}[/tex] (x) , that is

[tex]f^{-1}[/tex] (13) = [tex]\frac{13+2}{3}[/tex] = [tex]\frac{15}{3}[/tex] = 5
