Which choice describes the value of m when -5(m + 1) ≤ 23?

snow_tiger [21]

Answer:

Number 1

Step-by-step explanation:

-5(m + 1) ≤ 23

Distribute

-5m - 5 ≤ 23

-5m ≤ 23 + 5

-5m ≤ 28

-m ≤ 28/5

Since we divide by a negative the ≤ flips to ≥

m ≥ -28/5

Hope this helps :3

F(x)=-2x+10 what value of x will f(x)=0

trapecia [35]

For x=5 the function will be zero

Further explanation:

In order to find the value on which a particular function will be zero, the function is put equal to zero and the equation is solved for x.

Given function is:

$f(x)=-2x+10\\$

Putting the function equal to zero

$-2x+10=0\\Subtracting\ 10\ from\ both\ sides\\-2x+10-10=0-10\\-2x=-10\\Dividing both sides by -2\\\frac{-2x}{-2}=\frac{-10}{-2}\\x=5$

For x=5 the function will be zero i.e.

f(x)=0

We can verify:

$f(5) = -2(5)+10\\=-10+10\\=0$
