Answer:
<h2>$4.7</h2>
Step-by-step explanation:
step one:
Let the cost be y
to solve for the cost of a movie ticket, we need to solve the expression
y=2.75+0.10x
step two:
given that x is the number of years between 1980-2000
the number of years is 20years
put x= 20 in the expression for the cost we have
y=2.75+0.10(20)
y=2.7+2
y=$4.7
We have been given that the circular opening of an ice cream cone has a diameter of 7 centimeters. The height of the cone is 10 centimeters. We are asked to find the volume of the ice-cream cone.
We will use volume of cone formula to solve our given problem.
, where
r = Radius of cone,
h = Height of cone.
We know that diameter is two times the radius, so radius will be half of diameter that is 
.
Therefore, the volume of the cone would be approximately 128.3 cubic cm.
Answer:
they are congruent
Step-by-step explanation:
they have the same points
Based on the above scenario, an equation that shows how much Gwen paid. The equation for Gwen is y = 100 + 10x
- The equation for Tristan is y = 12.5x
- The equation for Keith is y = 10x.
<h3>What is the
equation about?</h3>
Since Gwen burns about 10 cal/min. THen she had used up 100 calories if Tristan and Keith began ar (Y g=100 if x=0)
Then Y(g)= 10x + 100
Since Tristan is known to burns 125 cal in 10 minutes always, then one can write her own as 12.5 cal every minute.
Therefore Y (t) = 12.5x
Since Keith burns 300 calories in 30 min always, or 10 calories in every minute.
Then Y (k) = 10x
The general function of y:
y=10x +100 + 12.5x + 10x
y = 32.5x + 100
Therefore, Based on the above scenario, an equation that shows how much Gwen paid. The equation for Gwen is y = 100 + 10x
- The equation for Tristan is y = 12.5x
- The equation for Keith is y = 10x.

First, we need to evaluate the function to get two points, and then we connect them with a line.
<h3>
How to graph a linear function in math?</h3>
The linear function in the slope-intercept form is:
f(x) = a*x + b
Where x is the variable.
To graph it, we need to find two points on the line, to do that, we evaluate in two values of x. Let's use x = 0 and x = 1.
for x = 0:
f(0) = a*0 + b = b
for x = 1:
f(1) = a*1 + b = a + b
Then we have the points: (0, b) and (1, a + b).
Now we only need to graph these two points and connect them with a line, that line will be the graph of the linear function.
