Answer: y= -2x + 12
or f (y ) = 6 -
Step-by-step explanation:
just subtract the 2x to get the y alone
Let the number of bike be x and the number of skates be y, then
21x + 20y ≥ 362 . . . (1)
2y = x . . . (2)
Putting (2) into (1), then
21(2y) + 20y ≥ 362
42y + 20y ≥ 362
62y ≥ 362
y ≥ 5.84
The least number of pairs of skates they need to rent each day to make their minimum is 6.
Answer:
for x < 0 x^2 - 2
for x
0 2x + 1
Step-by-step explanation:
So all you have to do to solve these problems is substitute the y coordinate and the x coordinate into the equation.
So question 1 would be true because when you substitute the numbers in it equals the y value.
Question 2 is (4, -7)
Question 3 is False
Question 4 is true
Question 5 is true
See if you can do the rest!
The numbers are 4 and 2! 4 plus 2 equals 6! and 6 plus 4 is equal 10!
