Answer:
Rule: y = 2x
m = 2
b = 0
Step-by-step explanation:
(17, 34) and (22, 44)
<u>Slope:</u>
m=(y2-y1)/(x2-x1)
m=(44-34)/(22-17)
m= (10)/5
m = 2
<u>Slope-intercept:</u>
y - y1 = m(x - x1)
y - 34 = 2(x - 17)
y - 34 = 2x - 34
y = 2x
y = mx + b
y = 2x
b = 0
Answer:
Step-by-step explanation:
21 is c
Answer:
No solution
Explanation:
-4+19-7f = -15-7
cancel terms on both sides ( add 7f on both sides)
Calculate the sum
-4+19= -15
-4+19=15
15 = -15
The statement 15 = -15 is false so there is no solution :)
Answer:
(-2, 1)
Step-by-step explanation:
Hi Juliadayx! How are you?
Well, maybe you already heard about the domain and the range of a function.
The domain is the set of values that the independent variable can take (usually referred to as the letter "x"), while the range is the set of values that the dependent variable takes, which is called f(x) or function of x.
In this case, the exercise asks you to evaluate for which values of “x” (right column of the table), the function “f(x)” takes positive values (left column of the table), the positive values also include zero. And in this case you can see that the function f(x) is only positive for the values of "x": -2, -1, 0 and 1. Therefore, the answer is the entire interval (-2, 1).
I hope I've been helpful!
Regards!
