Answer: m∠6=18
3x-15=x+7
add 15 to both sides
3x-15+15=x+7+15
3x=x+7+15
3x=x+22
subtract x from both sides
3x-x=x+22-x
3x-x=22
2x=22
divide both sides by 2
2x÷2=22÷2
x=22÷2
x=11
plug it into the equation
11+7=18
m∠6=18
I hope this is good enough:
Since h represents the height of the ball at any given time, t, let h = 25, such that the ball will be 25m high at t.
Now, we have 25 = 20t - 5t²
5t² - 20t + 25 = 0
t² - 4t + 5 = 0
Since the discriminant is less than zero, there are no solutions.
Hence, the ball will never be 25m high.
Answer:
The equation of the line is
Step-by-step explanation:
Equation of a line is
Where m is the slope
c is the y intercept
y = 2x + 3
Comparing with the above formula
m is 2
Since the lines are perpendicular the slope of the other line is the negative inverse of the original line .
That's
m = - 1/2
Equation of the line using point (1,2) and slope - 1/2 is
y - 2 = -1/2(x - 1)
y - 2 = -1/2x + 1/2
y = -1/2x + 1/2 + 2
The final answer is
Hope this helps you.
