Answer:
Step-by-step explanation:
we need a function that when we plug the value of x, we get the given value of y.
In the coordinate point
(-9, -3)
the x and y values are:
x = -9
y = -3
so we can see that the value of y is one third of the x value (because -9/3 = -3):
this is also true for the secod point:
(-12, -4)
here the x and y values are:
x = -12
y = -4
again the y value is one third of the x value (because -12/3 = -4):
⇒ this is the equation that represents the function.
Answer:
Step-by-step explanation:
We start by subtracting from both sides of the second inequality:
Therefore, we conclude that:
Therefore, every point that satisfies the system has a -coordinate greater than
.
Answer:
(A) 2 meter
Step-by-step explanation:
It is given that the ladder forms a 72º angle with the ground and rests against the house at a spot that is 6 meters high.
Let the measure of bottom of the ladder from the wall be x, then using the trigonometry, we have
≈
Thus, option A is correct.
