Given:
Line A: 2x + 2y = 8
Line B: x + y = 4
x = 4 - y
2(4-y) + 2y = 8
8 - 2y + 2y = 0
0 = -8
y = 4 - x
2x + 2(4-x) = 8
2x + 8 - 2x = 8
0 = 0
There is no solution.
Answer:
36 feet.
Step-by-step explanation:
We have been given that a ball is thrown upward from ground level. Its height h, in feet, above the ground after t seconds is
. We are asked to find the maximum height of the ball.
We can see that our given equation is a downward opening parabola, so its maximum height will be the vertex of the parabola.
To find the maximum height of the ball, we need to find y-coordinate of vertex of parabola.
Let us find x-coordinate of parabola using formula
.



So, the x-coordinate of the parabola is
. Now, we will substitute
in our given equation to find y-coordinate of parabola.






Therefore, the maximum height of the ball is 36 feet.
Answer:
a) x=60°, 2x=120°
b) x=36°
Step-by-step explanation:
A = lw + lw
A = (2)(11) + (2)(3)
A = 22 + 6
A = 28 yd²
Answer:

Step-by-step explanation:
The denominators are the same. You can add the numerators without any extra work.

The denominator factors as (2x-3)(3x+4), so there are no factors that will cancel with the numerator.
