Answer:

no solutions

Step-by-step explanation:

4 + 5m = 4m + 1 + m combine like terms

4 + 5m = 5m + 1 subtract 5m from each side

4 = 1

4 can never equal 1, so no value of m would allow the equation to be correct

<h3>Answer: C) No solutions</h3>

The left side 4+5m is the same as 5m+4

Simplifying the right hand side has 4m+1+m turn into 5m+1

The original equation is equivalent to 5m+4 = 5m+1

If we subtract 5m from both sides, the 5m terms cancel leaving us with 4 = 1, but that's not a true statement.

Regardless of whatever value you pick for m, the original equation will not be true.

Evaluate-a-function f(x) = <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B7%7D" id="TexFormula1" title="\frac{x}{7}" alt="\f

OLga [1]

Step-by-step explanation:

Hey there!

f(x) = 7/x

~ Simply keep the "7" in the place where "x" is there.

$f(7) = \frac{7}{7}$

Therefore, X= 1.

Hope it helps....

Given: Q=7m+3n,R=11-2m,s=n+5,and T =-m-3n+8 simplify Q-[R+S]-T

Gnesinka [82]

Answer:

Simplify

$Q-[R+S]-T$

The answer is:

$10m+5n-24$

Step-by-step explanation:

We have the expressions:

$Q=7m+3n\\R=11-2m\\S=n+5\\T=-m-3n+8$

Now, we need simplify:

$Q-[R+S]-T$

We need to replace each term by the expressions:

$7m+3n-[(11-2m)+(n+5)]-(-m-3n+8)$

We need to remember the rule of signs:

$-/-=+$

$-/+=-$

$+/+=+$

With this in mind we solve the parentheses:

$7m+3n-[(11-2m)+(n+5)]-(-m-3n+8)$

$7m+3n-[11-2m+n+5]+m+3n-8$

$7m+3n-11+2m-n-5+m+3n-8$

let's group common terms

$7m+3n-11+2m-n-5+m+3n-8\\7m+2m+m+3n-n+3n-11-5-8$

We must add and subtract common terms:

$7m+2m+m+3n-n+3n-11-5-8\\10m+5n-24$

The answer is:

$10m+5n-24$

Im desperate to find the answer please give an explanation to how you got the answer

Olin [163]

Just draw the graphs, and you should find y = 10x² is the only graph narrower than the given one.
