Answer:
3 values
Step-by-step explanation:
2x +8 <22 and 3x >9
Solve the two inequalities separately and then put them back together
2x +8 <22
Subtract 8 from each side
2x +8-8 <22 -8
2x < 14
Divide by 2
2x/2 < 14/2
x < 7
Then solve the second inequality
3x>9
Divide by 3
3x/3>9/3
x >3
Putting them back together
x>3 and x < 7
Since it has to be an integer
4,5,6 are possible choices
3 values
Plug the numbers in for x to see which make the equation true.
Answer:
y = 2x - 2
Step-by-step explanation:
y = mx + b
Sub x = 5, y = 8, and b = -2 into the equation.
8 = 5m - 2
Isolate the m-term and solve for m.
8 + 2 = 5m -2 + 2
10 = 5m
Divide both sides by 5 to isolate m.
m = 2
Sub the parameters (m and b) into the template to get your equation.
y = 2x - 2
Divide $1,137.50 by 350 to see out how much each book costs. Then divide $1,500 by 350 to see how much the school should add to the price of each agenda book to make the total profit. So the answer should be: (1137.50/350)+(1500/350) = minimum price
