Answer:
a = 7
Step-by-step explanation:
The function given is defined at x=1 as ...
f(1) = 3·1² = 3
In order to make the limit from the left be 3, we must have ...
ax -4 = 3 . . . . for x=1
1a = 7 . . . . . . .add 4
The value of the constant "a" is 7.
Answer:
-2x+3y =1.......(1)
y=3x-9........(2)
Now,
putting the value of y in equation (1),
-2x+3(3x-9)=1
or,-2x+9x-27=1
or,7x-27=1
or,7x=28
x= 4
Now putting the value of X in equation (2),
y=3×4-9
= 12-9
=3
(x,y)=(4,3)

Answer:
Pedro hits 1471 times and Ricky hits 1195 times.
Step-by-step explanation:
Pedro has 276 more hits than Ricky.
So, p = r + 276 ....... (1)
And their total hits is equal to 2666.
p + r = 2666 ........ (2)
Now, substituting the value of p from equation (1) to equation (2) we get,
r + 276 + r = 2666
⇒ 2r = 2390
⇒ r = 1195
Hence, from equation (1) we get p = r + 276 = 1471.
Therefore, Pedro hits 1471 times and Ricky hits 1195 times. (Answer)
