Step-by-step explanation:
We can write
X=-2,-1,0,1,2
And the equation is y=3x+4-------(1)
First we should be put all the value in equation (1)
y=2,1,4,7,10
And the answer will
(x, y) ={ (-2,2),(-1,1),(0,4),(1,7),(2,8)}
Answer:
5 hours
Step-by-step explanation:
1. Find out how many dollars he earned on Saturday
3 x 6 = 18
He earned 18 dollars on Saturday.
2. Subtract 18 from 48 since that is from Saturday, not Sunday
48 - 18 = 30
3. Divide 30 by 6 to see how many hours he worked on Sunday
30/6 = 5
Answer:
25. a = 60
26. a = 17
Step-by-step explanation:
In these two problems we are going to use a property of parallelograms that says: opposite angles have equal measure
so we have
25.
and for 26 we have
Answer:
a) 5.13beats/min
b) 2.82 beats/min
Step-by-step explanation:
Given the pulse rate of a person modelled by the equation y = 600x^-1/3 for 30≤x≤75
If the height is 39inches, the instantaneous rate of change of pulse rate for the heights will be expressed as;
y = 600(39)^-1/3
y = {600(1/39)}/3
y = 600/39×3
y = 600/117
y ≈ 5.13beats/min
The instantaneous rate for a 39 inches tall person is 5.13 beats per min
b) For a 71inches tall person, the beat rate will be expressed as;
y = 600(71)^-1/3
y = {600(1/71)}/3
y = 600/71×3
y = 600/213
y ≈ 2.82 beats per minute
The instantaneous rate for a 71 inches tall person is 2.82 beats per min
