The abscissa is the x-coordinate of the ordered pair and the ordinate is the y-coordinate. The ordered pair is therefore given to be,
(abscissa, ordinate)
or (x , y)
From the given, it is stated that the ordinate is three more than twice the abscissa. The ordered pair can therefore be written as,
(x, 2x + 3)
If x = -1 then,
y = 2(-1) + 3 = 1
Ordered pair : (-1, 1)
If x = 0
y = 2(0) + 3 = 3
Ordered pair : (0, 3)
Hence, the answer to this is either the first choice or the second choice which appears to be just the same.
Answer:
30
%
Step-by-step explanation:
Assumption: the increase is to be expressed as a percentage of 10.
We change from 10 to 13 so the increase is 3 We now need to change this into a percentage.
In fraction form we have increase Original value → 3 10 But we need to change this into the form some number 100 Let the unknown value be x giving: 3 10 ≡ some number 100 = x 100 To change the 10 from 3 10 into 100 we multiply by 10 Multiply by 1 and you do not change the value.
However, 1 comes in many forms.
3 10 × 1 = 3 10 × 10 10 = 30 100 This is the same as 30 × 1 100 but 1 100 is the same as %.
So 30 100 → 30 %
Answer:
Yes
Step-by-step explanation:
<u>Data</u>
The equation we have to use is:
A = P(1 – r)^t
Replacing with data:
A = 500(1 – 0.15)^15
A = 43.7 mg
This means that, after 15 hours, the current amount of the drug on her system will be 43.7 mg, which is less than 50 mg. So, it will be safe for her to drive.
