Answer:

n < 9

Step-by-step explanation:

Because n+4 < 13

So n have to less than 13 - 4 = 9

n less than 9 can be also written as n < 9

So in this case, to make the sum of n and 4 always no more than 13, n have to less than 9.

Hope this help you :3

Answer:

\Huge \boxed{N

Step-by-step explanation:

To solve this problem, first you have to isolate it on one side of the equation. Subtraction property of equality is subtract from both sides of an equation the same number doesn't change the equation.

First, subtract 4 from both sides.

\displaystyle n+4-4

Solve.

\displaystyle 13-4=9

In conclusion, the correct answer is n<9.

a_sh-v [17]

In unit of batches over days, let r be the planned rate and R be the actual increased rate. The difference between R and r is described as 10 shirts per day.

R-r=10

                        Rate                  Time                  Batches

Planned              r                          8                           1

Actual                 R                         7                            1


\left[\begin{array}{c}r=1/8&R=1/7&R-r=HowManyBatchesInTenShirts\end{array}\right]

1/7-1/8, the number of batches equivalent to 10 shirts.

(1/56)*Batches=10*Shirts

OneBatch=560*Shirts

Hello there!

x² + x = 7/4
x² + - 7/4 = 0

Now we gonna use the quadratic formula to find x
a= 1
b=1
c = -1.75

x = -b+/-√b² -4ac all of them divide by 2a
x = -(1)+/-√(1)² - (4)(1)(-1.75) all of them divide by 2(1)
x= -1+/-√8 all of them divide by 2
x = -1/2 + √2 or x = -1/2 - √2

The correct option is option C

I hope that helps!

1) f(x) + g(x)

= 7√x + 4 + 2√x - 2

= √x(7 + 2) + 2

= 9√x + 2  [ Final Answer ]

2) f(x) - g(x)

= 7√x + 4 - (2√x - 2)

= 7√x + 4 - 2√x + 2

= √x(7 - 2) + 6

= 5√x + 6   [ Final Answer ]

Hope this helps!
