Answer:
5) (x, y) = (10, -1)
6) (x, y) = (5, 6)
Step-by-step explanation:
5) y coefficients are opposites, so y can be eliminated by adding the two equations.
(x -y) +(2x +y) = (11) +(19)
3x = 30 . . . . . simplify
x = 10 . . . . . . . divide by 3
Using the second equation, we can find y:
2(10) +y = 19
y = -1 . . . . . subtract 20
The solution is (x, y) = (10, -1).
__
6) The x-coefficients are the same, so we can eliminate the x-term by subtracting the second equation from the first. We choose to do it that way so the y-coefficient ends up positive.
(-6x +6y) -(-6x +3y) = (6) -(-12)
3y = 18 . . . . . . simplify
y = 6 . . . . . . . . divide by 6
Using the first equation to find x, we have ...
-6x +6(6) = 6
x -6 = -1 . . . . . . . divide by -6
x = 5 . . . . . . . . . add 6
The solution is (x, y) = (5, 6).

Answer:
153/20
Step-by-step explanation:
We want to have the mixed fraction turned into a improper fraction to make adding them both easier. We would change 5 2/8 to 42/8 and 2 4/10 to 24/10.
We now need to get them a common denominator. The LCM (least common multiple) of 8 and 10 is 40, so we multiply 42/8 by 5/5 getting us 210/40 and 24/10 by 4/4 to get 96/40.
Finally, we add them then simplify. 96/40 + 210/40 is 306/40. We then simplify that to 153/20.

cos x= 3/4, s in quadrant 1
Answers
Answer: x = 41.4°
Step-by-step explanation:
We want to solve:
Cos(x) = 3/4
Such that this is on quadrant 1.
(if x is in degrees, the possible values of x will be: 0° ≤ x ≤ 90°)
To solve this we need to remember the inverse functions.
If we have two functions f(x) and g(x), these functions are inverses if:
f( g(x) ) = x
g( f(x) ) = x
Then the inverse of the cosine function (this function is "arcos(x)") is such that:
Arcos( cos(x) ) = x
Then in our equation:
Cos(x) = 3/4
We can apply the inverse function to both sides to get:
Arcos(Cos(x)) = Arcos(3/4)
x = Arcos(3/4)
(To find the Arcos function in your calculator, you need to use the button "inv" and then the "cos" button, and remember to have your calculator in deg mode)
x = Arcos(3/4) = 41.4°

The point (–3, –5) is on the graph of a function. Which equation must be true regarding the function?
a. f(–3) = –5
b. f(–3, –5) = –8
c. f(–5) = –3
d. f(–5, –3) = –2
Answers
Answer:
a. f(–3) = –5
Step-by-step explanation:
On a graph, point (x, y) can be also represented as function f (x) = y
it means that if f(x) has input value as x then its output value will be y.
Now given that in the problem that
The point (–3, –5) lies on the graph
it means that for function input value of of -3 has the out put value of -5
which can also be written as
f(-3) = -5
Hence the correct choice is a. f(–3) = –5.
