Find the value of x for mAB=34 and mCD=25 (The figure is not drawn to scale.)
Alexus [3.1K]
<h3>Answer:   29.5 degrees</h3>

==============================================

Explanation:

Add up the arc measures and divide by 2 to get the angle formed by the two chords.

angle AOB = (arc AB + arc CD)/2

angle AOB = (34 + 25)/2

angle AOB = 59/2

angle AOB = 29.5 degrees

find the equation of a line that is parallel to the straight line 2x-y=-3 and crosses the x-axis at x=-5​
Alecsey [184]

Answer:

y=2x+10

Step-by-step explanation:

In line equations its helpful to write your line in the form y = ax + b. This helps because a is always the gadient of the line and b is always the y intercept.

In this case it is y=2x+3

All parallel lines have the same gradient. The gradient of this line = 2.

If the line crosses the x axis at x=-5, then when x =-5 y = 0.

If you put all this in the form y =ax + b you get 0 = 2(-5) +b

So all you need to do to find b is rearrange. b = 10.

Therefore your line has gradient 2 and y intercept 10.

y = 2x + 10

How are the rules for adding and subtracting negative numbers similar to adding and subtracting positive numbers? Justify your r
Fantom [35]

Answer: the rules are

+(+) Two like signs become a positive sign

−(−) 6−(−3) = 6 + 3 = 9

+(−) Two unlike signs become a negative sign

−(+)

Step-by-step explanation:

Example:  3+(+2) = 3 + 2 = 5, 6−(−3) = 6 + 3 = 9, 7+(−2) = 7 − 2 = 5,8−(+2) = 8 − 2 = 6  hope this helps you :)
