When adding and subtracting with exponents....combining like terms....exponents are not added/subtracted...but coefficients are.
example : 2b^2 + 3 + 3b^2 = 5b^2 + 3
but keep in mind, they have to be like terms to be able to add and subtract them...for instance 2b^2 + 3b^3...u cannot add/subtract them because they are not like terms.
Answer:
Step-by-step explanation:
Answer: The answer for this question would be answer choice B "(0, 10) and (1, 15)". (0, 10) represents her starting amount and week saved, and (1, 15) would represent her saving for one week and having $15 total.
Hope this helps!
Answer:
A. 6.681.060.239
Step-by-step explanation:
a1 = 7
r = (-8)
n= 11
S11 = 7((-8)^11 - 1)/ (-8-1)
= -7/9 ( -8,589,934,591)
= 6.681.060.239
Answer:
Three-fourths
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
∠QSR≅∠XZY ---> given problem
∠QRS≅∠XYZ ---> given problem
so
△QRS ~ △XYZ ----> by AA Similarity theorem
Remember that, if two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
That means
∠Q≅∠X
∠R≅∠Y
∠S≅∠Z
<em>In the right triangle XYZ</em>
Find the tangent of angle X
---> opposite side angle X divided by adjacent side angle X
substitute the given values
Simplify
Remember that
∠Q≅∠X
so
therefore
---->Three-fourths
