Answer:
8 I dont know
Step-by-step explanation:
One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).
Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.
The unit rate is 2,86:2,50
Answer: x=-3
Step-by-step explanation:
First, it is important to understand that the domain is all possible x values and the range is all possible y values. So for this specific graph, the domain is -4≤x≤-1 and 0≤x<3) and the range is -1<y≤4. The second and fourth choices are correct.
First, we know the graph is not defined for all values of x because the domain only refers to certain x values.
The second choice is true because the range extends from -1 to 4, so 4 is the largest possible value.
The third statement is incorrect because even though our domain extends from -4 to 3, 3 is noninclusive (open circle).
Choice four is correct: that is the same as the range listed above.
The last choice is incorrect because no x values between -1 and 0 are defined.
Hope this helps.
Answer:
x=3
Step-by-step explanation:
⇒
y
=
3
x
Explanation:
Direct proportionality is defined as:
y
=
α
x
where
α
is some constant that defines the proportionality.
Given
x
=
2
and
y
=
6
, we find:
y
=
α
x
6
=
α
(

)
3
=
α
So the relationship here is
y
=
