Answer:
0.5.
Step-by-step explanation:
Substitute x = -3 into the guiven function:
= 2(-3) - 1/2(-3) + 5
= -6 + 1.5 + 5
= -4.5 + 5
= 0.5
Answer:
positive
Step-by-step explanation:
From the number line
x>0 so it is positive
y <0 so it is negative
xy = positive * negative
= negative
-xy = negative * negative
= positive
Answer:
First table
Step-by-step explanation:
We have to find the set of value which could be from a direct proportion.
We know that
Direct proportion :
When x is directly proportional to y


Where k=Proportionality constant

K remain constant when x and y are in direct proportion
From first table




When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.
From second table
not ]define

It is not direct proportion because k does not remain constant.
From third table


It is not direct proportion because k does not remain constant.
Answer:
f(-2)=3
Step-by-step explanation:
we know that
f(-2) is the value of the function f(x) for the value of x equal to -2
so
Observing the graph
For x=-2
f(-2)=3
