Answer:
You can use 3x-8=22
Step-by-step explanation:
You can add 8 to both sides and then divide both sides by 3. x will equal ten.
Substitute y = 2x + 3 into y = -x - 9
2x + 3 = -x - 9
Solve for x in 2x + 3 = - - 9
x = -4
Substitute x = -4 into y = 2x + 3
y = -5
Therefore,
<u>x = -4</u>
<u>y = -5</u>
Answer:
Step-by-step explanation:
Next time, please enclose the quantity in the denom. inside parentheses, to eliminate any ambiquity regarding what the divisor is.
2x 2(x)
f(x) = --------------- = -------------------
3x² - 3 3(x - 1)(x + 1)
This is the same as:
2 x
--- * ------------
3 (x-1(x+1)
As x grows large, the 2nd fraction approaches 1/x as a limit, which goes to zero. Hence, the end behavior involves the x-axis as the horizontal asymptote. This agrees with the first answer choice.

that does not make sense ?????????????????????????????????????????
Answer:
The answer is c :" Mary should isolate the x term because she can then simplify the remaining expression to solve for x."
Step-by-step explanation:
From the equation as written below,
(x-4)(x-1)= 60
the first step is expansion of the bracket, thus we have,
x2-4x-x+4=3(2)60
which equals
x2-5x+4=3(2)60
then the next step should be to isolate x terms to be on one side of the equation while she continues solving for x,
x2-5x= 3(2)60-4
This is because in such simple equations, x could only be found if all terms of x are isolated in one side of the equation before continuing other processes such as factorization,etc.
