Answer:

Step-by-step explanation:
In order for the triangle to be a right one we need every side to be of the same length. see the photo for furyher explanation.
Answer:
infinite solutions
Step-by-step explanation:
replace x with 3y + 9 in the second equation
9 - (3y + 9) = -3y ➡ 9 -3y -9 = -3y ➡9-9 = 3y-3y ➡ 0 = 0
this means whatever numver you write instead of y there will be a solution.
Step-by-step explanation:
x = -12
y = x/2 + 9
y = -12/2 + 9
y = -6 + 9
y = 3
Answer:
A)2
Step-by-step explanation:
we would like to integrate the following definite Integral:

use constant integration rule which yields:

notice that we can rewrite √x using Law of exponent therefore we obtain:

once again use law of exponent which yields:

use exponent integration rule which yields;

simplify which yields:

recall fundamental theorem:

simplify:

hence
our answer is A
