The trick to solving this problem is to realize that the independent variable is x, which represents the number of people who can attend the party without the total party cost exceeding $80.
This is the form of the inequality:
(total cost) [less than or equal to] $80
(rent) + (cost per guest)(number of guests) [less than or equal to] $80
$45 + $5.50 x [less than or equal to] $80
Simplify. To do this, subtract $45 from both sides of this inequality.
Divide both sides of the resulting inequality by $5.50.
What is the restriction on x?
Hi!
Let's write it in slope intercept form first.
y = mx + b
Subtract y intercepts
1 - (-2) = 3
Subtract x intercepts
2 - (-3) = 5
y = 3/5x + b
Substitute one of the points to find y intercept.
1 = 3/5 · 2 + b
1 = 1.2 + b
-0.2 = b
y = 3/5x - 0.2
Now substitute the point (5,3), and if the equation is still correct, then it does pass through that point.
5 = 3/5 · 3 - 0.2
5 = 1.8 - 0.2
5 = 1.6
Since the equation is in correct, the line does NOT pass through the point (5,3).
Hope this helps! :)
Answer: The equation would be 15 x 3x then after 8 days would be 360 because 15 x 3(8)=
15 x 24=
360
Step-by-step explanation:
The answer would be c 110
Answer:
A. 4x - 6 = -3x + 5
Step-by-step explanation:
you just have to take the first equation and substitute that in, in the second equation.
hope that helps. have a good day!
