45(x)-20
x=hours
7 hours
x=7
45(7)-20 =295
Answer:
y = 45(7) - 20

Answer:55
Step-by-step explanation:
7+6(8)
7+48
55
Answer:
7+ 6 x 8
Step-by-step explanation: Since c=8 you will basically replace the c with the 8 and you do the same with the 7 , d=7 so you replace d with a 7 and when you have a variable (x or another letter) next to a number you multiply so you get 7 + 6 x 8
(the x = multiplying)

as the summation of all angles in a triangle must be 180
∠H = 180 - (130 +20)
= 180-150
=30
as the straight line has an angle of 180
∠G= 180 - 130
= 50
since that
∠f = 180- (50+60)
=180- 110
=70
answer is C

This is the graph of a __function.
The y-intercept of the graph is the function value y=
The smallest positive x-intercept of the graph is located at x=
The greatest value of y is y=___, and it occurs when x=
For x between x = π and 2π, the function value y ___ 0
Answer:
1) Cos
2) 1
3) π
4) 1
5) y < 0
Step-by-step explanation:
1)
Cos
2)
The y-intercept is the value of y when x=0, ie the value of y when the line meets the y-axis. We can see from the graph that this is 1.
3)
The x-intercept is the value of x when y=0, ie the value of x when the line meets the x-axis. We can see from the graph that the smallest positive value of x when the line crosses the x-axis is π.
4)
Highest y value from graph is 1, and besides, for cos graphs, y≤1.
5)
We can see from the graph that between x=π and x=2π, the function is bellow the y-axis, ie y<0.
The graph is of a cos function. The y-intercept of the graph is the function value y=1. The smallest positive x-intercept of the graph is located at x=π. The greatest value of y is y=1, and it occurs when x=2π. For x between x = π and 2π, the function value y<0.
The point on the graph where it crosses the y-axis is known as the y-intercept. The y-intercept in this situation is zero since the graph crosses the y-axis at (0, 0).
The point at which the graph first crosses the x-axis at a positive value of x is known as the graph's smallest positive x-intercept. The graph in this instance crosses the x-axis at (x,0), making the smallest positive x-intercept.
The maximum value of the function is equal to the highest value of y. The greatest value of y in this situation is 1, and it happens when x = 2.
The function value y declines from 1 to 0 for x between x = and 2. You can observe this by examining the graph.

Elena plays the piano for 30 minutes each practice day.
The total number of minutes p that Elena practiced last week is a function of n, the number of practice days.
What is the domain for this function?
What is the range of this function?
Answer:
Step-by-step explanation:
f(n)=30n
domain all real numbers
range all real numbers
I think.
Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.
What is a function?A relation is a function if it has only One y-value for each x-value.
The function that relates the total number of minutes practiced, p, to the number of practice days, n, is given by:
p = 30n
where 30 is the number of minutes Elena practices each day.
Since we cannot have negative practice days, the domain of the function is the set of non-negative integers:
Domain: {0, 1, 2, 3, ...}
The range of this function is the set of all possible values of p that can be obtained by plugging in values of n from the domain.
In this case, since the function only outputs non-negative values, the range is the set of non-negative integers:
Range: {0, 30, 60, 90, ...}
Hence, Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.
