Find the nonpermissible replacement for y in the expression y+3/y+3
Ugo [173]

Answer:

Non-permissible value is y=-3

Step-by-step explanation:

we are given equation as

f=\frac{y+3}{y+3}

we know that denominator can not be zero

so, we can set denominator =0

and then we can solve for y

y+3=0

we can subtract both sides by 3

y+3-3=0-3

y=-3

So,

Non-permissible value is y=-3

Brainliest for the correct answer with the correct working out! If n is an integer, what numbers of n such that −1 ≤ n + 7 <
8_murik_8 [283]

Answer:

−1 ≤ n + 7 < 9

To solve a compound inequality separate it into two inequalities

That is

n + 7 ≥ - 1 and

n + 7 < 9

Solve the inequality

n + 7 ≥ -1

n ≥ - 8

and

n + 7 < 9

n < 7 - 9

n < 2

Find the intersection

The final answer is

-8 ≤ n < 2

Hope this helps

Find two numbers whose product is 100 and whose sum is a maximum?
brilliants [131]
Let them be X and Y..
now...
yx=100 ....
y=100/y ...
now...
x+y= s....where s is their sum...
but y=100/x
now....x+100/x=s..
by differentiating both sides with respect to x..
1-100/x^2=ds/dx
but ds/dx=0..
100=x^2 ..
x=10..
so y=10
