Answer:
answer3
beacuse to find the x-intercept, substitute in 0 for y and solve for x
.
-x^2
Is that x times -x?
positive times a negative is negative
and you add the exponents when multiplying like base
Q-2r=4, therefore: q=4+2r.
Plug the value of q into q+r=37, so you get:
4+2r+r=37
3r=37-4=33
3r=33
Therefore: r=11.
q-2r=4, but r=11, so:
q-2(11)=4
q-22=4
Therefore q=26.
Check if the answer is correct using second equation:
q=4+2r=4+2(11)=4+22=26.
So: q=26 and r=11.
Answer:
1: The doctor's measurement.
Step-by-step explanation:
The doctor's measurement is correct because the doctor measured Claire's brother and Claire only estimated, therefore there is no evidence that Claire is correct but there's Is evidence that the doctor is correct.
You just plug in both numbers in the x of the equation and then multiply by 4 and subtract by the 3
