What the heck do you mean??????????
Answer:
7:15
Step-by-step explanation:
There are 15 students total, and 7 of them are going on the trip. Therefore, we write that as 7:15
Answer:
To find the x-intercepts we can write:
0 = -1/2(x + 3)² + 4
0 = -1/2(x² + 6x + 9) + 4
0 = -1/2x² - 3x - 9/2 + 4
0 = -1/2x² - 3x - 1/2
0 = x² + 6x + 1
x = -3 ± 2√2 (use quadratic formula)
As a decimal this can be written as x = -5.83, x = -0.17.
Y =mx+b y=2x+3
m is the slope
b is your yintercept [write it as a point (0,b) ]
Step 1: Plot the y intercept (0,3)
Step 2: Trace slope from yintercept ... go 2 place up them 1 place right you should end up on the point (5,1)
Step 3: Draw a line through the two points
