Which of the following relation is a function.
Answer:
Which of the following relations is a function- A
Determine which relation is a function- A
Step-by-step explanation:
A function is a type of relationship where x's do not repeat. So, to solve find where each y has a unique x value. In the first question, A is correct because the x values; -3, 0, 2; never repeat. Then, on the next question A is correct because it is a relation written in slope-intercept form, which is a type of function notation.

Please somebody help me out!!
Answer:
See below.
Step-by-step explanation:
These work just like ordinary algebraic expresssions, except you have to remember always: i^2 = -1 i squared is negative one!
(4 - 3i)(4 + 3i) "FOIL" the expression to get 16 - 3i + 3i - 9i^2. But i^2 = -1, so this is the same as 16 - 3i + 3i + 9. Combine like terms.
Ans. 25
(4 - 3i)(i) Distribute the i to the two terms of the binomial.
4i - 3i^2 = 4i - 3(-1)
Ans. 4i + 3
(6i)(4 + 3i) = (6i)(4) + (6i)(3i) = 24i + 18i^2 = 24i + 18(-1)
Ans. 24i -18
(6i)(i) = 6i^2 = 6(-1)
Ans. -6
(-5)(4 + 3i) = -20 - 15i That's it; there's no i^2 to deal with.
Ans. -20 - 15i
(-5)(i) = -5i Again, that's all there is to it.
Ans. -5i

SOLVE THE SYSTEM USING ELIMINATION!!!!
HURRY ILL GIVE BRAINLIEST!!
Answer:
(5,3)
Step-by-step explanation:
add the equations to eliminate to x's and get 8y=24
divide both sides by 8 to get y=3
then substitute in -2x+3(3)=-1 to solve for x
so x=5 so the solution is (5,3)
Answer:
[tex]x=5 \\y=3[/tex]
Step-by-step explanation:
[tex]-2x+3y=-1\\2x+5y=25[/tex]
Add these equations to eliminate x:
[tex]8y=24[/tex]
Then, solve [tex]8y=24[/tex] for y:
[tex]8y=24[/tex]
[tex]\frac{8y}{8} =\frac{24}{8}[/tex] (divide both sides by 8)
[tex]y=3[/tex]
Now let's find the value of x:
Substitute 3 for y in [tex]-2x+3y=-1[/tex]
[tex]-2x+(3)(3)=-1[/tex]
[tex]-2x+9=-1[/tex] (simplify both sides of the equation)
[tex]-2x+9+-9=-1+-9[/tex] (add both sides by -9)
[tex]-2x=-10[/tex]
[tex]\frac{-2x}{-2} =\frac{-10}{-2}[/tex] (divide both sides by -2)
[tex]x=5[/tex]
Therefore, the value of x = 5 and y = 3

O c. 7
O D. 5
Answer:
A
Step-by-step explanation:
The requried simplified value of x in the intersection of two lines is 6.
What are opposite angles?Opposite angles are a pair of angles that are formed when two lines intersect. The two angles are located on opposite sides of the point where the two lines intersect.
Opposite angles are also called vertical angles, and they have equal measures. This means that if we know the measure of one opposite angle, we can find the measure of the other opposite angle by setting them equal to each other.
Here,
When two lines intersect, opposite angles are equal. So, we can set the two opposite angles equal to each other and solve for x.
Given that the opposite angles are 3x + 2 and 20 degrees, we have:
3x + 2 = 20
Subtracting 2 from both sides, we get:
3x = 18
Dividing both sides by 3, we get:
x = 6
Therefore, the value of x is 6.

Step 1: Factor out the common term [tex]-1[/tex]
[tex]=-\left(5\frac{3}{4}+3\frac{1}{2}\right)[/tex]
Step 2: Add the whole numbers

9
86.3 m
D)
177.9 m
Answer:
A) 67.4 m
Step-by-step explanation:
Let "x" represent how many meters above the lake is the man
Reference angle = 32°
Opposite = x
Hypotenuse = 129.5 m
Apply ye trigonometric function SOH:
Sin 32° = Opp/Hyp
Son 32 = x/129.5
129.5 × sin 32° = x
x = 68.6245447
This is close to A) 67.4 m
