What is the domain in interval notation of f(x)=(x+3)^2
Given:
The function is
[tex]f(x)=(x+3)^2[/tex]
To find:
The domain of the given function in interval notation.
Solution:
We have,
[tex]f(x)=(x+3)^2[/tex]
Domain is the set of x-values or input values.
The given function is a quadratic function and domain of the quadratic function is all real number. The function is defined for all values of x. So, domain of the given function is the set of all real numbers.
Domain = Set of all real numbers
Domain = (-∞,∞)
Therefore, the domain of the given function is (-∞,∞).

Answer:
see below
Step-by-step explanation:
6y = 12x + 26
15y = 45x + 60
First let's simplify these equations.
6y = 12x + 26
Divide each term by 6.
y = 2x + 26/6
Simplify the fraction.
26/6
= 13/3
Your simplified equation is:
y = 2x + 13/3
Let's simplify the other equation.
15y = 45x + 60
Divide each term by 15.
y = 3x + 4
These are your simplified equations.
y = 2x + 13/3
y = 3x + 4
We can see that the slope of the first equation is not equal to the slope of the second equation.
equation 1: slope is 2 shown from 2xequation 2: slope is 3 shown from 3xThe y-intercept of the first equation is not equal to the y-intercept of the second equation.
equation 1: y-intercept is 13/3 shown by + 13/3equation 2: y -intercept is 4 shown by + 4Now we want to solve the equations.
Both equations are equal to y, so you can set them equal to each other.
2x + 13/3 = 3x + 4
Combine like terms.
1/3 = x
Plug x = 1/3 into both of the equations separately..
y = 2(1/3) + 13/3
y = 2/3 + 13/3
y = 15/3
y = 5
y = 3(1/3) + 4
y = 3/3 + 4
y = 1 + 4
y = 5
Your solution is (1/3, 5)
The system of equations has one solution.

Help me please if it right I give brainliest I promise
Answer:
48,400 yd²
Step-by-step explanation:
(220+180)/2*260=52000
1/2(180)(60)=5400
So the total area is 52000+5400=57400
Basketball court=2400
Picnic area = 4200
Playground = 40x50 + 10x40=2400
2400+4200+2400=9000
57400-9000=48400

Step-by-step explanation:
3 times a day Dylan mixes 2 oz of protein powder into a shake how many days can he make all 3 shakes from his 5 oz container of protein powder you #16 oz in a #
Answer:
13 days
Step-by-step explanation:
Protein powder in container = 16 oz
Number of containers = 5
Total ounces of protein powder = (16 * 5) = 80 oz
Oz of protein used per shake = 2 oz
Number of times shake is made per day = 3
Total oz used per day = 2 oz * 3 = 6 oz
Number of days hencan make all three shakes from container :
Total ounces / ounces per day
80 oz / 6 oz
= 13. 33 days
