Answer: 2.10
Step-by-step explanation: 2.10 * 4 + 6
Answer:
C) -2 ≤ x ≤ 2
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see that our x-values span from -2 to 2. Since they are both closed dots, we include them in the domain:
[-2, 2] or -2 ≤ x ≤ 2
Answer:
y= -1/4x - 5
Step-by-step explanation:
first you need to find the slope.
to do this you can use the equation: change in y/change in x which is also y2 - y1/x2-x1
-8 - (-6)/12-4
-2/8
-1/4 = slope
since the line's equation is y = mx + b, we still need to find the y-intercept. we can do this by just plugging in one of the points
-6 = -1/4(4) + b
-6 = -1 + b
-5 = b
so the final equation is y= -1/4x - 5
--Percent means out of 100, so 20% = 20/100
The prob in other words is asking
-- $60 is 20% of what number?
'$60' -- ---> 60
'is' -- ---> =
20% -- ---> 20/100
'of' -- ---> * (multiply)
'what number' ---> x (variable)
