-3x+3y=12
Y= x+4
The solution set of this system is best explained by which of these statements?
Answers
Answer:
C
Step-by-step explanation:
Reform the first graph: -3x + 3y = 12; 3y = 12 + 3x; y = 4 + x; y = x + 4Compare y = x + 4 and y = x + 4: they are equal, thus the same slope (1) and the same y-intercept (4)Related Questions

You're playing the ring toss at a carnival. In one round of the game, you either hit your target and win, or you miss the target and lose. What is the probability you will win one round of the game?
Answers
Total probability in round 1 is 1
And there are two likely outcomes which are win and lose
And as such there is an equal probability for both to happen
Also , the sum of the two outcomes should be 1
(Win + Lose ) = 1
(1/2) + (1/2) =1
Hence the probability that round 1 is won is 1/2

Two angles are supplementary. The measure of the larger angle is 12 less than 3 times the measure of the smaller angle.Find the measure of each angle
Answers
Answer:
48 , 132
Step-by-step explanation:
Let smaller angle = x
Larger angle = 3x - 12
x & (3x - 12) are supplementary
So, x + 3x - 12 = 180°
4x - 12 = 180
4x = 180 +12
4x = 192
x = 192/4
x = 48°
Larger angle = 3*48 - 12 = 144 - 12 = 132
Answer: The measure of the smaller angle is 48,and the larger angle is 132.

B.
The function is an odd function because .
C.
The function is an even function because .
D.
The function is an odd function because its graph is symmetric about the y-axis.
Answers
Answer:
B. The function f(x) = tan(x) is an odd function because f(-x) = -f(x)
Step-by-step explanation:
The function f(x) = tan(x) is odd as [tex]f(-x) = -f(x)[/tex] so we can conclude the statement B. The function f(x) = tan(x) is an odd function because [tex]f(-x) = -f(x)[/tex] is the true option.
What are functions?The function is a relation used to determine a value f(x) for a given x using an expression in x.
What are even functions?An even function is when f(x) = f(-x). It is symmetric along the y-axis.
What are odd functions?An odd function is when f(-x) = -f(x). It is symmetric along the x-axis.
How do we solve the given question?We are dealing with the function f(x) = tan(x).
We calculate f(-x) = tan(-x) = -tan(x) = -f(x).
∴ The function f(x) = tan(x) is an odd function, and odd functions are symmetric about the origin.
∴ The function f(x) = tan(x) is odd as [tex]f(-x) = -f(x)[/tex] so we can conclude the statement B. The function f(x) = tan(x) is an odd function because [tex]f(-x) = -f(x)[/tex] is the true option.

Answers
The expected number of defective bolts are obtained as 175. The correct option is (C).
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lie in the close interval of 0 and 1 [0,1].
The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.
The total number of bolts tested are 24.
And, the number of defective bolts are 5.
Then, the probability of defective bolts is given as,
P(defective bolts) = 5/24
Now, the expected number of bolts can be found as,
Expected number = P(defective bolts) × Total number of bolts tested
⇒ 5/24 × 850 = 175
Hence, the expected number of bolts that will be defective is given as 175.

what is 0.75x – 100 ≤ 80
Answers
Answer: X is less than or equal to 240
The solution to the inequality 0.75x - 100 ≤ 80 is x ≤ 240.
Given is an inequality what is 0.75x – 100 ≤ 80, we need to solve it,
To solve the inequality 0.75x - 100 ≤ 80, we can follow these steps:
1. First, let's isolate the variable x by adding 100 to both sides of the inequality:
0.75x - 100 + 100 ≤ 80 + 100
0.75x ≤ 180
2. Next, we can divide both sides of the inequality by 0.75 to solve for x:
(0.75x) / 0.75 ≤ 180 / 0.75
x ≤ 240
Therefore, any value of x that is less than or equal to 240 will satisfy the inequality.
Therefore, the solution to the inequality 0.75x - 100 ≤ 80 is x ≤ 240.

if you are counting up or down you go to (input the value) the y. if you want to find J for example, (the y coordinate) you go to the black dot and you count starting from 0. usually it will have the points -5 -4 -3 -2 -1 0 1 2 3 4 5 but in your problem it does not have so you just have to count carefully.

Answer:
x = 12
Step-by-step explanation:
The diagonals PN and MO are perpendicular bisectors of each other, thus
QO = MQ , substitute values
3x - 10 = 2x + 2 ( subtract 2x from both sides )
x - 10 = 2 ( add 10 to both sides )

The modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).
What are the laws of Kepler?There are three laws, made by the Kepler, to explain the motion of the planet around the sun.
First Law-According to this law, all the planets moves in the elliptical orbits. The center of this orbital path is the Sun. Thus Planetary orbits are elliptical. Second Law-The planet moves in elliptical orbit. The line of planet and sun sweeps out equal mass in equal time.Third Law-The square of the period of a planet to complete one path of electrical orbit is directly proportional to the cubes of semi-major axis of their orbit.Earth’s rotation causes the rising and setting of the sun because of the earth's rotation on its axis.
Hence, the modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).
