Hey there!
We may ask. What exactly is a term anyways.
Well, a term is a single number, a variable, or a number and a variable that would have to be multiply together. This is what a term would be.
Therefore, as we look above, we see the following equation.
9a+4b-18
18 is a term
4b is a term
9a is a term
This whole thing, would be called an expression, as this is expression something. Perhaps the amount of students who ate ice-cream at a football game, or something similar.
I hope you found this helpful! :)
-10.3 + y = 5.2
First, regroup the terms. / Your problem should look like:
Second, add 10.3 to both sides. / Your problem should look like:
Third, add 5.2 + 10.3 to get 15.5 / Your problem should look like:
Answer:
y = 15.5 (D)
The correct answer is B.
Determine and recall first the trigonometric functions:
Sin A = Opposite/Hypotenuse
Cos A = Adjacent/Hypotenuse
Tangent = Opposite/Adjacent
If for example we try to take an angle, for example the Y, then Y is opposite Y. The Hypotenuse will be the longer side which is going to denoted by X and the next side will be Adjacent which will be denoted by Z.
Use this test to answer:
Sin Y = Y/X
where:
Y = opposite
X = hypotenuse
Cos (90 - y) = cos (90 - 50) = cos 40
where Z = 40
we look for cos Z = Y/X
Therefore,
Sin Y = Cos (90 - Y)
Answer:
A
Step-by-step explanation:
pythagorean theorem
A^2+B^2=C^2 do that for all sides then add
