Answer:
x = -9
Step-by-step explanation:
Given:
BC = x + 19
ST = x + 29
Required:
Value of x
Solution:
Midsegment theorem states that the midsegment of a triangle = ½ of the length of its third side
Thus:
BC = ½(ST)
Substitute
x + 19 = ½(x + 29)
Multiply both sides by 2
2(x + 19) = x + 29
2x + 38 = x + 29
Collect like terms
2x - x = -38 + 29
x = -9
We have that
<span>y=2x-1
and
Y=2x+3
the two lines are parallel
because the slopes are the same
m=2
we know that
</span>If two lines are parallel<span>, then they will never intersect

therefore
the answer is the option

Answer:
..-9, -27, -81....
Step-by-step explanation:
Each term after the first is found by multiplying the previous term by 3.
So its ..-9, -27, -81......
2x + 50 = 7x
50 = 5x
10 = x
2 (10) + 50
20 + 50
70
m<AEB = 70 degrees

it is unbiased because the people are chosen at random
