5x-10=3x+40
5x=3x+50
2x=50
x=25
5*25=125
125-10=115
angle AEB=115
Hope this helps :)
To solve this problem, we will need the standard kinematics equation
where
v0=initial velocity (positive upwards) m/s
t=time in seconds
a=acceleration due to gravity (positive upwards) = -9.81 m/ ²
Substituting values,
distance = 0 (when it falls back on earth)
v0=42 m/s
a=-9.81 (negative means towards earth, downwards)
factor and solve
=>
t=0 (beginning of launch), or
42-(1/2)*9.81t=0 => t=2*42/9.81=8.563 s.
Time to return = 8.6 seconds (to the nearest tenth of a second)
Answer:
If a vehicle does not have 4 wheels, it is not a car.
Dont forget to give brainliest and thanks
Explanation:
f(x) = (x-4)(x+2)
1) For x-intercept, y will be 0
<u />
<u>x-intercept</u>: (4, 0), (-2, 0)
2) For vertex: x = -b/2a where ax² + bx + c
<u>Quadratic function</u>:
<u>vertex</u>:
y: (x-4)(x+2) = (1-4)(1+2) = -9
ordered pair of vertex: (1, -9)
3) For y-intercept, x will be 0
<u>y-intercept</u>: (0, -8)
Hi!
So, x is going to be the price of one apple. We need to solve for x, so let's start with getting an equation up and running.
<em>3x + 0.84 = 5x
Now, we're going to subtract three from both sides.
3x - 3x + 0.84 = 5x - 3x
Now, we're going to divide 2 from both sides!
0.84 / 2 = 2x / 2
And our final answer is... 0.42 for each apple! =)
