Put x=-2 in x-y=-2
-2-y=-2
-y=0
y=0
x=-2
that's your answer.
Answer:
20 is not a coefficient
True - constants are numbers that donʻt have a varible
Step-by-step explanation:
I hope this helps stay safe and have a good day! Can i get a brainiest if correct?
In the binomial expansion of (0.30+0.70)²⁰ the coefficient is ²⁰C₁₀=184756 for x=10 and we have 0.30¹⁰×0.70¹⁰ for the pq values where q=1-p. This comes to about 0.03. So the statement p(x=10)=0.50 is false, answer b.
Answer:
both are 75 degrees
Step-by-step explanation:
the angles add up to 180, as they are also vertical angles
Answer:
A.) -9
Step-by-step explanation:
it is observed that triangles ABL and KML are similar triangles
hence the following ratios are valid:
LA / LK = LB/LM = AB/KM
we can see that LA/LK = LB/LM = 1/2
hence the above ratio becomes
1/2 = AB/KM (rearranging)
KM = 2AB
We are given that KM = (x + 21) and AB = (x + 15)
hence
KM = 2AB
(x + 21) = 2 (x + 15)
x + 21 = 2x + 30
x - 2x = 30 - 21
-x = 9
x = -9
