Answer:
The value of a is
The equation is
Step-by-step explanation:
we know that
The function of a vertical parabola written in vertex form is equal to
where
(h,k) is the vertex of the parabola
in this problem we have
substitute in the equation
Find the value of the coefficient a
Substitute the value of x and y of the point in the equation
The equation is equal to
----> is a vertical parabola open downward
Answer:
30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles
150 = ?+120
Subtract 120 from each side
150-120 = ?
30 = ?
Here in this case the answer is "a". The way to find the percentage is to add all the numbers you have which is $49. And then you need to use it to divide it with the percentage you need for the number. Which in this case you are searching for shoelaces and it $4. So you divide the cose of the shoelaces $4 to the total amount $49. And then you multiply by 100 to get the percentage. If you round it off the the tenth place you should get 8.2%
Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x+x+3=18
(4x+x)+(3)=18(Combine Like Terms)
5x+3=18
5x+3=18
Step 2: Subtract 3 from both sides.
5x+3−3=18−3
5x=15
Step 3: Divide both sides by 5.
5x/5 = 15/5
x=3
