The list of choices you included doesn't have any correct expressions on it.
-- If the rocket went straight up, and then dropped back at the same place
it was launched from, then it must have dropped straight down.
-- The route it followed on the way down was exactly the same as the
route it followed on the way up.
-- Since it reached a maximum height of 150-ft from the ground
and the route was straight, the length of the route was 150-ft.
-- (150-ft going up) plus (150-ft coming down) = 300-ft traveled all together.
Answer:
x = 29°
y = 29°
z = 102°
Step-by-step explanation:
x and y both look even to the 29° angle across from them and z looks even to the 102° angle across from it.
Since it's a linear equation and there's a constant rate (given in the problem), we can choose our x - axis to be the time and the y - axis to be height. We choose it that way because you are going up in the elevator. The more time in the elevator, the higher you go.
Finding this equation uses the point slope formula, y - y₁ = m(x - x₁). It can be done with slope-intercept, y = mx + b too.).
First we need to get the slope of the line. Choose any two points, but be consistent and choose two y points as well as the matching x ones. Here, we use x₁ = 2, x₂ = 4, y₁ = 45, y₂ = 75. Slope, m, is y₂ - y₁ / x₂ - x₁.
m = 75 - 45 / 4 - 2
= 30 /2
= 15
Next, we use the slope of 15 and either of the points to find the linear equation. Choose the same (2, 45) x-y pair above, but any point will work.
y - 45 = 15 (x - 2)
y - 45 = 15x - 30
y = 15x + 15
So the linear equation representing this table us y = 15x + 15.
Answer is :Y is the easiest first using second equation . Ill show you steps below why . If you want to see the steps .
2x+4y=26
3x+y = 9
So first solve second equation
3x+y=9
Y= -3x+9
Now plug into first equation
2x+4y=26
2x+4(-3x+9)=26
2x-12x+36=26
-10x+36=26
-10x= 26-36
-10x= -10
X=1
So now solve for y in second equation
Y= -3x+9
Y= -3(1)+9
Y= -3+9
Y= 6
So if you were to be asked answer in point (1,6).
If you were looking for the greatest common factor, you'd want to see the list of their factors.
A prime factorization breaks it down as far as possible and as a result has as few high numbers as possible. If you want the number to be as great as possible, you would want to see the list of all the factors.
