x= -3, -11
Answer:
f(x) = -3x + 4
Second option
Step-by-step explanation:
In function notation, the <u>"y" variable is isolated and replaced with "f(x)"</u>.
Isolate "y" by keeping "y" on the left and moving everything else to the right. To move something, do its reverse operation to both sides.
9x + 3y = 12
9x + 3y - 9x = 12 - 9x Do -9x on both sides
3y = -9x + 12
3y/3 = -9x/3 + 12/3 Divide by 3 on both sides
y = -3x + 4 Change to function notation
f(x) = -3x + 4 Answer
Answer:
Cup cakes= $3
Bear claws = $10
Step-by-step explanation:
Let the orice of cupcakes be x and the price of bear claws be y
5x+ 3y= 45
4x + 6y= 72
Multiply equation 1 by 4 and equation 2 by 5
20x + 12y= 180
20x + 30y= 360
-18y= -180
y= 10
Substitute 10 for y in equation 1
5x + 3(10)= 45
5x + 30= 45
5x = 45-30
5x= 15
x= 15/5
= 3
Hence the price of cup cakes is 3 and bear claws is $10
Answer: 8/3
Step-by-step explanation:
Ok, if you want to find out the range of the hours they play, here it is:
Since the number of hours for Bonnie are 4, 5, 4, 3, 3, 5, the range should be 3, 4, 5, which makes the range 3.
Since the number of hours for Adele are 5, 5, 9, 8, 8, 7, the range should be 5, 7, 8, 9, which makes the range 4.
Which means Adele's range is bigger than Bonnie's!
Hope this helped! c:
