A linear equation has maximum power of a variable(variables) 1.
In order to find the linear equations we need to check the equations with variable with power one.
Also the variable should be in numerator only.
Let us check option one by one:
a-y=√x + 1 we have a radical on x.
Therefore, it's not a linear equation.
b-y=1/x
We have x in the denominator of 1.
Therefore, it's not a linear equation.
c-y=x^2 +4
We have power 2 of x. Therefore, it's not a linear equation.
d-y = -2/3x + 4/3.
We have x and y powers only 1.
Therefore, it's the only linear equation.
<h3>Therefore, correct option is D option. d-y = -2/3x + 4/3</h3>
First add the fractions.
6/7 + 5/7 = 1 4/7
Then add the whole numbers
4 + 3 = 7
Then add the mixed number to the whole number
7 + 1 4/7 = 8 4/7
Your answer is 8 4/7
To find the height that the rocket has reached, we can use the following equation to calculate distance.
s = ut + 1/2 at²
s - distance - h
u - initial velocity - 64 ft/s x 0.3048 m/ft = 19.5 m/s
a - acceleration, since the rocket is travelling upwards against gravitational acceleration, its said to be deceleration. therefore value is -9.8 ms⁻²
t - time taken - t seconds
substituting values in the equation
h = 19.5 ms⁻¹ x t s - 1/2 x 9.8 ms⁻² x (t s)²
h = 19.5t - 4.9t²
