X/y = 4 , x = 4y
x^2 -12y^2 = (4y)^2 - 12y^2 = 16y^2 -12y^2 = 4y^2
Answer:
50b ≥ 560.
Step-by-step explanation:
Number of bikers on a team is b so the total number of miles ridden if each rides 50 miles is 50b. The team must complete at least 560 miles so the inequality is
50b ≥ 560.
Answer:
240.74
Step-by-step explanation:
y=±x*
X+21/2 is the answer i got.
The greater than 3 means that the graph will have a shaded region for when the absolute value of (x+1) is greater than 3.
The absolute value means that we are interested in the magnitude of x+1. That means that the the graph will be shaded where x+1 > 3, and where -x-1 > 3
If we solve both of these for x, we get:
x > 2 and x < -4
So the graph will look like the attached picture. Notice that the vertical lines are dotted rather than solid. This means that we are dealing with a greater than sign, not a greater than or equal to.
