— 25 — 3х + 5 or – 3х +5 — 31

zysi [14]

Answer:

both should

be equal to hope my work is correct or helps

Step-by-step explanation:

first one

-25<-3x+5 subtract 5 from both sides

-25-5=-30

5-5=0

then divide by -3

-30 divided by -3 =10

x=10

so it is equal to not less than

second one

-3x+5<-31

subtract 5 from both sides 5-5=0

-31 -5=-36

then divide both sides by -3

x=12

Solve. −35x+15>720 Drag and drop a number or symbol into each box to show the solution.

vampirchik [111]

Answer:

The solution of the inequality - 35x + 15 > 720 is $x$

Step-by-step explanation:

Consider the given inequality

- 35x + 15 > 720

Subtract both side by 15 , we get

- 35x + 15 - 15 > 720 - 15

- 35x > 705

Multiply both sides by -1 (Reverse the inequality )

(-35x)(-1) < 705 (-1)

35x < -705

Now, divide both side by 35

$\frac{35x}{35}=\frac{-705}{35}$

$\Rightarrow x=\frac{-141}{7}$

Thus, the solution of the inequality - 35x + 15 > 720 is $x$

4.) solve for f(g(2))

Westkost [7]

Answer:

$f(g(2))=10$

Step-by-step explanation:

We have the two functions: $f(x)=3x-5$ and $g(x)=2+\frac{6}{x}$ .

We want to find $f(g(2))$ .

So, let's use the second function to find $g(2)$ first:

$g(2)=2+\frac{6}{2}$

Divide:

$g(2)=2+3$

Add:

$g(2)=5$

Therefore, our expression is the same to $f(g(2))=f(5)$ .

Now, we can substitute 5 for f(x). This yields:

$f(5)=3(5)-5$

Multiply:

$f(5)=15-5$

Subtract:

$f(5)=10$

So:

$f(g(2))=10$

And we're done!
