Answer:
3
Step-by-step explanation:
company g is charging 10 per hour and in the graph when it is zero hours it shows the base charge which is 25 but in addition when you add an hour if you subtract that amount minus the flat amount 25 you will get 7 and will continue to do so as you continue across the graph 10-7 equals 3
<span>Using the form y = mx + b, where m = the slope and b = the y intercept
The x intercept occurs when y = 0, therefore to find b:
-1/4*8 + b = 0
-2 + b = 0
b = 2
therefore our equation is
y = -1/4x + 2,

Answer:
1500 students
Step-by-step explanation:
Divide the number of blonde students by the percentage they are of the school.
225/0.15 = 1500
The total number of students in your school is 1500.
Answer:
8√3 ≈ 13.86
Step-by-step explanation:
6√2 - 4√3 + | 3√(2²•2) -8√3 | + 2√2²•3
Every 2² get our from the square root and loses the ² :
6√2 -4√3 + | 2•3√2 -8√3 | + 2•2√3
Solve the multiplications and taking of the | | , the signal inside it changes:
6√2 - 4√3 +8√3 -6√2 +4√3
Now you group the similar terms and solve the possible operations:
6√2 - 6√2 +4√3 - 4√3 + 8√3
8√3 ≈ 13.86
Ok this inequality tells you the number of devices you can have before the new plan costs more than the old plan. The new plan expression is $4.50x + $94m = y ( total cost). The old plan is $175m = y (total cost). You can see m (number of months) in both equations, you don't need it this time since we're going to to compare both to one month. Since they're both equal to y you can make them equal to each other. $4.50x + $94 = $175. Now you want to figure when the new plan is less than the old plan you switch the equal sign for a less than sign. $4.50x + $94 < $175; this will help you find the inequality you want. From there just use algebraic steps to find that x has to less than 18 or
x < 18.
