Part A
The small red arcs indicate that angles PQS and RQS are congruent.
13x - 1 = 2(6x + 4)
13x - 1 = 12x + 8
x = 9
m<PQR = 13x - 1 = 116
m<RQS = 6x + 4 = 6(9) + 4 = 58
m<PQS = 116 - 58 = 58
Part B
12^2 + (OH)^2 = 13^2
144 + (OH)^2 = 169
(OH)^2 = 25
OH = 5
r = OH = 5
Part C
WZ/ZY = WX/XY
24/12 = 30/XY
2 = 30/XY
2(XY) = 30
XY = 15
Answer:
20.
m = -52
22.
x=13
24.
a=-90
26.
n=-2
28.
a=9
30.
m=-10
Step-by-step explanation:
20. m/4=-13
m = -13*4 = -52
22. -143=-11x
x=-143/-11 =13
24. -5=a/18
a=-5*18= -90
26. n-8=-10
n=--10+8
n=-2
28. a+11=20
a=20-11
a=9
30. 18+m=8
m=8-18
m=-10
Answer:
It's 2 1/4
Step-by-step explanation:
I dont know how to explain this... but I'm 100% positive on the answer so
Answer:

Step-by-step explanation:

Expanding brackets.

Adding 2m and 6 to both sides.

Combining like terms.

Dividing both sides by 14.

Let's put the chart into ordered pairs:
(x, y)
(2,1)
(3,4)
(3,3)
(4,2)
(5,5)
In bold, we see that there are two y-values at x=3. This means that this relation fails the vertical line test (two points on the same verticle line). This is not a function.
The answer options may be mis-written.
The answer is no, because one x value corresponds to more than one y-value.
