Answer:
x - 31
69
Tonisha has to make at least $100 in revenue
Step-by-step explanation:
Set up the inequality:
x - 31 represents her profit
Since she wants to make at least $69 a day, use
69
So, the inequality is x - 31
69
Then, solve for x to find how much she has to sell:
x - 31
69
x
100
So, Tonisha has to make at least $100 in revenue
Okay. Trying to look at it without anything else. F(4) is also saying x=4.
g(x) is another way of saying y= ... So if the question is asking what is x, then 4 is x.
Answer:
x=2 and y= -3
Step-by-step explanation:
This is a simultaneous equation. To solve this type of equation, there are three methods; substitution, Elimination and Graphical.
But here, we would be using the substitution method.
3x-y=9 Equation 1
2x-y=7. Equation 2
Getting y from equation 2, we have
-y= 7-2x
Multiply both sides by -
y= 2x-7 Equation 3
Substituting y for 2x-7 in equation 1, we have
3x- (2x-7)=9
3x-2x+7=9
x+7=9
x=9-7
x=2
Substituting x as 2 in equation 3
y=2x-7
y= 2(2)-7
y= 4-7
y= -3
