Write the equation of the line y=-11/3x+3 in standard form

The standard form of the equation of line will be;
⇒ 11x + 3y = 9
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The equation of line is,
y = -11/3 x + 3
Since, The standard form of the equation of line will be;
Ax + By = C
Where, A, B and C are integers.
Now, We convert the equation of line in standard form as;
The equation of line is,
y = -11/3 x + 3
Multiply by 3 in both sides,
3 × y = 3 (-11/3 x + 3)
3y = 3 × -11/3 x + 3 × 3
3y = - 11x + 9
3y = - 11x + 9
Add 11x both side;
11x + 3y = - 11x + 9 + 11x
11x + 3y = 9
Thus,
The standard form of the equation of line will be;
⇒ 11x + 3y = 9

Which of the following is(are) the solution(s) to |11x +3 = 6 ?
Answers
Hey there!
11x + 3 = 6
SUBTRACT 3 to BOTH SIDES
11x + 3 - 3 = 6 - 3
CANCEL out: 3 - 3 because it gives you 0
KEEP: 6 - 3 because it helps you solve for your x-value
11x = 6 - 3
11x = 3
DIVIDE 11 to BOTH SIDES
11x/11 = 3/11
CANCEL out: 11/11 because that gives you 1
KEEP: 3/11 because it simplifies for the x-value
SOLVE
x = 3/11
Therefore, your answer should bed x = 3/11

Alacrosse player throws a ball in the air from an initial height of 7 feet.
The ball has an initial vertical velocity of 90 feet per second. Another player catches the ball when it is 3 feet
above the ground. How long is the ball in the air? Round your answer to the nearest hundredth.
Answers
Answer:
Modeling the situation with a quadratic equation, it is found that:
The maximum height of the ball is of 60.2 feet.
The ball hits the ground after 3.39 seconds.
Considering the gravity, the height of the ball, after t seconds, is given by the following quadratic equation.
In which:
is the initial velocity.
is the initial height.
In this problem:
Height of 8 feet, thus .
Initial velocity of 32 feet per second,
The equation is:
Which is a quadratic equation with .
The maximum height is the output of the vertex, which is:
Then, with the coefficients of this question:
The maximum height of the ball is of 60.2 feet.
It hits the ground at t for which , thus:
We want the positive value, so:
The ball hits the ground after 3.39 seconds.

Brenna found 10% of 60. Her work is shown below.
10% of 60 = (60 = 2) = 30
O No. Brenna should have divided by 4 to find 10%.
No. She should have divided by 10 to find 10%.
O No. She should have multiplied by 10 to find 10%.
O Yes. Brenna did not make an error.
Answers
Answer: She should have divided by 10 to find 10% of 60 because percent in latin means per centum which means for 100 or per each 100 and dividing by 10 means that the result times 10 equals the original number, so you would need to divide by 10.

Answers
Answer: 6.4 and in fraction form 32/5
Answer:
32/5 or 6 2/5 which 6 2/5 is the simplified answer
Step-by-step explanation:
so first you want to turn your mixed numbers( 2 2/3 and 2 2/5) into fractions
so you turn 2 2/3 into a fraction by multiply 2 times 3 + 2 and you keep the denominator so it would be 8/3
Then you would do the same for the other one 2 times 5 +2 and that would be 12/5
The multiply 8/3 times 12/5 but cross simplify 3 and 12 make 12 four and make 3 one
so then your problem should look like this 8/1 times 4/5 and the answer is 32/5 or if you simplify it would be 6 2/5

Then given that faster bus reached in 3.5 hours.

H = 160t - 16t^2 = 16t(10 - t)
The minimum/maximum of a quadratic function is always exactly in between the 0 points (or any other points with equal value, as a parabole is symmetrical).
Let's solve for H = 0
16t(10-t) = 0
t = 0 or 10 - t = 0
t1 = 0, t2 = 10
the maximum is at (t1+t2)/2 = 5
H(5) = 16*5(10-5) = 80*5 = 400
