Substitution!
<span>y = 4x – 10...(1)
y = 2...(2)
You have y=2 here, substitute it in equation (1),
</span><span>y = 4x – 10
</span><span>2 = 4x – 10
</span>Add both sides by 10
12=4x
Divide both sides by 4
x=3
We have x=3, and y=2. ==> (x,y) = (3,2)
Answer:
$2.50 + j =$18.16
Step-by-step explanation:
what you would do is move the $2.50 below $18.16 and subtract, the total is what = j
Answer:
The exact value of cot(∅) is 2.5
Step-by-step explanation:
The picture of the question in the attached figure
we know that
An isosceles triangle has two equal sides and two equal interior angles
In his problem
In the right triangle ABD
---> adjacent side angle ∅ divided by the opposite side angle ∅
we have
The base of the isosceles triangle is five times the height
so
substitute
There are 8 weeks and 18 books. therefore you would multiply these numbers together.
the answer would be 144 different combinations.
not sure about the permutation or combination notation, but I got you on the first part!
