Answer:

x°=50°

Step-by-step explanation:

  • x°+(x+10)°+(x+20)°=180°
  • 3x+30=180°
  • 3x=180_30
  • 3x=150
  • finally divide both side by 3
  • x= 50.

your gym membership cost $33 per month after an initial membership fee. you paid a total of $228 after 6 months. writer an equat
grin007 [14]

Answer:

what i did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a  9-month total cost of $327

Step-by-step explanation:

cost = $33 per month + fee  

1.  c(m) = 33m + f

 33(6) + f = 228

198 + f = 228

f = $30 membership fee  

c(m) = 33m + 30

 2.  at 9 months:  33(9) + 30 = $327

hopefully this helps :)

have a nice day !!

Which number is an irrational number? (1 point)
NemiM [27]

Answer: The answer is (B). 1.01257486...

Step-by-step explanation:  We are given four real numbers out of which we are to select the one which is irrational.

Option (A) is 0.12, in which the digits after the decimal are terminating. So, the number is rational.

Option (B) is 1.01257486..., the digits after the decimal are non-terminating and non-recurring. So, the number is irrational.

Option (C) is 0.1212121212..., in which the digits after the decimal are non-terminating and recurring. So, the number is rational.

Option (D) is 0.11111111..., in which the digits after the decimal are non-terminating and repeating. So, the number is rational.

Thus, (B) is the correct option.

Answer:

y-intercept: (0,6)

slope = -2

equation: y = -2x + 6  

Step-by-step explanation:

1) First, identify the y-intercept. The y-intercept is the point at which the line intersects the y-axis. We can see that the line crosses the y-axis at (0,6), so that must be it.

2) Now, find the slope. Pick two points from the line. I chose (0,6) and (3,0). Then, substitute the two points' x and y values into the slope formula m = \frac{y_2-y_1}{x_2-x_1}and solve:

m = \frac{0-6}{3-0}\\m = \frac{-6}{3}\\m =  -2

So, the slope is -2.

3) With the found information, use the slope-intercept formula y = mx + b to write the line's equation. Substitute values for the m and b.

m represents the slope, so substitute -2 in its place. b represents the y-intercept, so substitute 6 in its place. This gives the following equation:

y = -2x + 6
