Answer:
The arc length is
Step-by-step explanation:
2πr(angle/360)
segment Bc is the diameter which means it's also supplementary.
If it's supplementary it should be 180 degrees.
Currently we know that arc AB is 30 degrees
180 - 30 = 150 degrees
angle ADC = 150 degrees.
plug in 150 in the angle it should be like 2πr(150/360).
the diameter is 7in and to find the radius it would be half of 7 which is 3.5in
2π(3.5)(150/360) = 9.1630
Make sure to round.
Final answer: 9.2cm

Answer:
x=52
Step-by-step explanation:
vertical angles are congruent so that means the angle measures are the same
so, you can set up this equation:
156=3x
and solve as follows:
156=3x
/3 /3
52=x
To prove that x=52 you can input 52 as x in the equation
156=3(52)
156=156

Find the y=mx+b
Answers
Answer:
y = 7/6x - 0.75
Step-by-step explanation:
To get the slope, you do rise/run. This means that to get from one point to the other, you would go 7 units up and 6 units to the right. Then the y intercept is where you start on the y-axis, which is -0.75.
Hope this helps!!
Answer:
y = 7/6x - 2/3
Step-by-step explanation:
Hi,
To begin, pick two points from the graph. Doesn't matter what you pick as long as they're two different ones. So let's choose...
(4,4) and (-2,-3)
To find y = mx + b, we have to start with the slope (m). To find the slope, we find the change in y over the change in x.
-3 - 4 = -7 (the change in y)
-2 - 4 = -6 (the change in x)
So the slope is -7/-6 which equals 7/6.
Now, we plug that into y = mx + b
y = 7/6x + b
To find the b value, we plug in a point and solve for b.
4 = 7/6 (4) + b
4 = 28/6 + b
Simplify the 28/6 so it's easier to solve...
4 = 14/3 + b
-2/3 = b
So your equation is y = 7/6x - 2/3
I hope this helps :)

What is the solution to the system of equation of 2x+3y=6 and x-3y=9
Answers
Answer:
x = 5
y = -4/3
Step-by-step explanation:
Solve by elimination by adding the two equations together:
2x + 3y = 6
x - 3y = 9
3y and -3y will cancel out. Then, solve for x:
3x = 15
x = 5
Plug in 5 as x into one of the equations, then solve for x:
x - 3y = 9
5 - 3y = 9
-3y = 4
y = -4/3
So, the answer is x = 5 and y = -4/3

H. (x, y) = (x + 9.y + 9)
J. (x,y) → (9x, 9y)
Answers
Answer:
(9x, 9y) dilation
Step-by-step explanation:
(9, 9y) is the answer because F is 180 degrees rotations, G is not real, H is translations, and J is dilations and dilations is multiplying which makes the transformation non congruent.

A store offers a discount of 40%. The discount price of a shirt is $42 . What is the regular price?
Answers
Answer:
$70 is the regular price of the shirt.
Step-by-step explanation:
One way in which to find the regular price here is to write the equation
0.60s = $42. A 40% discount is reflected in 100% - 40%, or 1.00 - 0.40, which comes out to 0.60.
If 0.60s = $42, then the regular price of the shirt is
s = ($42)/0.60 = $70
