Answer:
Number of dogs = 6
Number of burgers = 11
Step-by-step explanation:
Number of dogs = x
Number of burgers = 2x - 1
Cost of a dog = $ 1.50
Cost of 'x' dogs = 1.5x
Cost of a burger = $ 2
Cost of (2x - 1) burger = (2x -1) * 2 = 2x *2 - 1*2
= 4x - 2
Total amount collected = $ 31
1.5x + 4x - 2 = 31 {add 2 to both sides}
1.5x + 4x = 31 + 2
1.5x+ 4x = 33
5.5x = 33
x = 33/5.5
x = 6
Number of dogs = 6
Number of burgers = 2*6 - 1 = 12 - 1 = 11
We have a formula for that( according to the Intersecting chords theorem)
3×4=2×jk
6=jk
Answer:
is the inequality that reflect the relationship.
Step-by-step explanation:
Given:
Charge for rental = $100
Additional charge = $ 35
Minimum amount that can be spent = $280
To Find:
equations or inequalities that reflect the relationship = ?
Solution:
Let x be the minimum number of hours
then the charge will be
100 + (number of hours)(additional cost per hour)
That is
100 + 35x
Now the minimum charge amount is $280 So, The charge can be 280 or more than 280
Equation of a line;
y=mx+c
m=5
y=5x+c
Replacing for x and y using point (-2, -1)
-1=5(-2)+c
-1=-10+c
c=-1+10
c=9
y=5x+9
The lowest value of the range of the function shown in the graph is -2.
<h3>What is range of a function?</h3>
The range of a function is the set of its possible output values.
In other words, the range of a function is the complete set of all possible resulting values of the dependent variable (y), after we have substituted the domain or independent variables.
The range value are the y values of the graph shown.
Therefore, the lowest value of the range of the function shown on the graph is -2.
