Make the question more clear please and i think the stem and leaf plot is incorrect.
Answer:
AC = 55°
Step-by-step explanation:
In this geometry, arcs AC and BD have the same measure. The sum of the parts of arc CD will total the measure of CD.
AC + AB + BD = CD
2AC +80 = 170
AC = 110/2 = 55
The measure of arc AC is 55°.
Answer:
No, (3, 9) is not a solution of the system.
Step-by-step explanation:
y=3x
2x-y=6
-----------
3(3)=9
2(3)-9=6-9=-3, not 6
Answer:
y=10x+75
Step-by-step explanation:
Because y-y1 = m(x-x1)
Plug in the y1(5) and x1(-7)
So, y-5 = 10(x+7)
= y=10x+75
A) -22
b) 62
c) 5.29
hope this helps
