Answer: if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min)*$0.35
Step-by-step explanation:
Here x will represent the number of minutes.
with $60 you have 450 minutes, and you must pay 60 regardless of how much minutes you use.
so if 0 < x ≤ 450, y = $60.
now, if you call for more than 450 minutes, you get an additional of $0.35 per minute, then we have:
if 450 < x ; y = $60 + (x - 450min)*$0.35
where we use (x - 450)*$0.35 because any minute after the 450 minute mark is considerated an additional time.
So our piecewise function is:
if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min)*$0.35
if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min) × $0.35
the calculation is as follows:Here x will represent the number of minutes.
so if 0 < x ≤ 450, y = $60.
And,
if 450 < x ; y = $60 + (x - 450min) × $0.35
where we use (x - 450) ×$0.35 since any minute after the 450 minute mark is considered an extra time.

3(x+2) = 3x+6
3x + 2x = x2(3+2)
3x+2 - 3(x+2)
-3(2+ )--6-3
Answer:
the answer is 3(x+2) = 3x=6
Step-by-step explanation:
3(x+2) = 3x+6 = 3 multiplies by x=3x 3 multiplied by 2=6 so it would be 3x+6
3x + 2x = x2(3+2)= 3x+2x= 5x its impossible to do 2x multiplies by 3 cause there is no similar variables there needs to be x in both
3x+2 - 3(x+2)= same as above there's no similar variables

Answer:
x =12
Step-by-step explanation:
We use the Pythagorean theorem
a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse
x^2 + 5^2 = 13^2
x^2 +25 =169
Subtract 25 from each side
x^2 +25-25=169-25
x^2 = 144
Take the square root of each side
sqrt(x^2) = sqrt(144)
x = 12

Answer:
x = 32
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp side / hypotenuse
sin 30 = 16/ x
Multiply each side by x
x sin 30 = 16/x * x
x sin 30 = 16
Divide each side by sin 30
x = 16/ sin 30
x = 16 / (1/2)
x = 32
Answer:
c, x = 32
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp side / hypotenuse
sin 30 = 16/ x
Multiply each side by x
x sin 30 = 16/x * x
x sin 30 = 16
Divide each side by sin 30
x = 16/ sin 30
x = 16 / (1/2)
x = 32

What is Maya’s biking speed?
PLZ HELP IN A BIG RUSH PLZ PLZ PLZ
Answer:
Maya's biking speed is 8 miles per hour.
Step-by-step explanation:
She can run 18 miles in 3 hours. That means she could run 6 miles in one hour. So, if she can ride her bike 18 miles in 2 hours she can bike 9 miles per hour.
If she bikes for 27 (3 hours) miles and runs 9 miles (1.5 hours) then taking the total of miles dividing it by the time you would get Maya's speed.

Answer:
Equal, equal, not equal, not equal
Step-by-step explanation:
A) Equal, because they have the same height and base. To find the area of a triangle, you use "(b+h)/2". In this situation, the "b" and the "h" are equal.
B) Equal, as they also have the same height and base. To find the area, you use b*h, and they are equivalent.
C) Not equal. The two lengths given are not equal.
D) Not equal. The two triangle's heights are equal, but their bases are not. If you look at the second triangle, you can see that if is further from the triangles' intersections. This means that the base is larger than the one on the left.

If you were to plug x = -6 into the equation, you'd find the x+6 portion turns to 0. Any smaller x value is not allowed because x+6 would be negative. We cannot take the square root of a negative value to get some real number.
Put another way, solving [tex]x+6 \ge 0[/tex] leads to [tex]x \ge -6[/tex]
In terms of transformations, [tex]y = \sqrt{x}[/tex] becoming [tex]y = \sqrt{x+6}[/tex] means the graph has been shifted 6 units to the left. The original domain [tex]x \ge 0[/tex] becomes [tex]x \ge -6[/tex], as the domain has also shifted the same 6 units.
Visually, the left most point on the graph will directly determine the smallest domain value. The domain is the set of all allowed x inputs.
The -7 at the end does not affect the domain at all. We can replace it with anything you want, and the domain will still be the same. This value affects the range only.

Given: m arc AB = 4x, m arc BC = 3x
m arc CD = 2x, m arc DA = 3x
Find: m∠APB
Answer:
a > m/bp
Step-by-step explanation:
flip the equation
abp > m
divide both sides with bp
abp/bp > m/bp
a > m/bp
Answer:
m<APB = 30 degrees
Step-by-step explanation:
The sum of angles in a circle is 360 degrees. Add up all the arcs to get the equation : 4x+3x+2x+3x=360 degrees.
x is equal to 30 degrees
m arc AB = 4x = 120 degrees
m arc DC = 2x = 60 degrees
By secants exterior angles, m<APB = 1/2(m arc AB - m arc DC) = 1/2(120-60) = 30 degrees.
The answer is m<APB = 30 degrees

To find the Median arrange the data in order from least to greatest then find the middle number. To find the middle number cross of one from the front and one from the bcak. If there are 2 numbers left in the middle add those numbers together and them divided the sum by 2.
The mean is the average of the numbers. It is easy to find. First, add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
