Step 1: Add 3x to both sides to get 4 = 3x - 1
Step 2: Add 1 to both sides to get 5 = 3x
Step 3: Divide by 3 on both sides to get 5/3 = x
Answer: 8
Step-by-step explanation: on the left chain, there are 5 4’s, so 4 times 5 is 20 Because you know that, subtract it from 60 to only have the W’s values. So 60-20 is 40 and because there is 5 w’s do 40/5 is 8. Therefore, the value of the w’s is 8 and the value of the 4’s is 20
Answer: D
Step-by-step explanation:
Try to draw the X and Y axis: When you shift the function to left it translates as going to the left of the X axis. So what you want is that every value of X on the parent function to correspond to the same x value minus four.
You can apply the same logic to get the + 6
Total miles = 70 + 70 = 140 miles
Total time = 140 miles / 57 mph = 2.456 hours
Time 1: 70 miles / 70 mph = 1 hour
Time 2: 70 miles / x mph
Total time = time 1 + time 2:
2.456 = 1 hour + 70/x
Subtract 1 hour from both sides:
1.456 = 70x
multiply both sides by x:
1.456x = 70
Divide both sides by 1.456:
x = 70/1.456
x = 48.0769 miles per hour
Rounded to 2 dp = 48.08 miles per hour
Answer:
Step-by-step explanation:
if x is the bill and y is the tip ten
x+y>14.50
x<2 and x≤ 2
when the sign is< then the dot has to be clear , because 2 does not count and x is less than 2 and not equal to 2
when the sign is ≤ the dot on the graph is solid which represent the equal to.
