Answer:
B
Step-by-step explanation:
To find the slope m use any 2 ordered pairs from the table.
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 4, 11) and (x₂, y₂ ) = (2, - 1)
m =
=
= - 2 → B
Answer:
B. x < 24
Step-by-step explanation:
16 > - 8 + x
+8 > +8 + x Add 8 to both sides
24 > x
Final answer: x < 24
Answer:
1st angle will 60degree =90-60,. 1nd angle =60 degree.vertically opposite angle,
Answer: B, x=20; angle measure is 30°.
Step-by-step explanation:
Opposite angles are always the same.
You can see that 30° and 3x are opposite angles therefore 3x=30°.
In algebra, when a letter and a number are next to each other, it means times.
So, 3x=30° means 3 times something equals 30.
And we know that 3×10=30 so, x=10.
Hope this helps :)
(180-x) + 18 + 30 + x/2 = 180
=> 180 + 48 - x + x/2 = 180
=> -x/2 + 48 = 0
=> x/2 = 48
=> x = 48×2 = 96°
