The answer is y=-x+30. You find the y intercept by looking at where the function hits 0 on the x axis.
Answer:
√28 = 2√7 or roughly 5.29
Step-by-step explanation:
work backwards! sqr of 28 = x^2 that equals 28
√28 = 2√7 or roughly 5.29
The plot: x meters wide and (x+30) meters long with an area of 15000 m^2. the equation you're searching for is:
x meters * (x+30) meters = 15000 m^2 or
x^2 + 30x m^2 = 15000 m^2 and
x^2 + 30x - 15000 = 0 <== that's the equation.
ans: x^2 + 30x - 15000 = 0
Let the length of the 2 equal pieces be x m. Then the length of the third piece = 0.25x m.
So we have the equation:-
2x + 0.25x = 54
x = 54 / 2.25 = 24
So the length of the 3 pieces are 24,24 and 6 meters.
Answer:
30
Step-by-step explanation:
<A=90°(opposite Angles)
➜2x+x+90=180
➜3x+90=180
➜3x=180-90
➜3x=90
➜x=90/3
<h3>➜x=30</h3>
