I can't figure out the second answer please help!!!

Mekhanik [1.2K]

Choice A is one of the answers. Nice work. This is because x+x+x turns into 3x.

Choice D is the other answer because 2(x+1) + x = 2x+2+x = 3x+2. You can find this through trial and error. Or you could graph y = x+x+x+2 and y = 2(x+1)+2 to find that they are the same exact identical diagonal line. A non-graph approach would be to set up a table of values to see that the two tables are identical.

If 2x-4(3-x)=18, then x=_____? Can someone please help me with this problem

denis-greek [22]

Answer:

Answer is below

Step-by-step explanation:

Simplify both sides of the equation.

$2x-4(3-x)=18\\2x+(-4)(3)+(-4)(-x)=18$

DIstribute

$2x+-12+4x=18\\(2x+4x)+(-12)=18$

CLT

$6x+-12=18\\6x-12=18$

Add 12 to both sides.

$6x-12+12=18+12\\6x=30$

Divide both sides by 6.

$\frac{6x}{6} =\frac{30}{6}\\ x=5$

Given that f(x) = 10x + 45, find f(7)

sattari [20]

Answer:

$\boxed{\bf f(x) = 115}$

Step-by-step explanation:

<u>Given polynomial </u><u>function </u>:-

$f(x) = 10x + 45$

<u>To </u><u>find</u> :-

$\sf \: f(7)$

<u>Solution:-</u>

$\sf \implies \: f(x) = 10x + 45$

Here, the value of x is 7(given).

So, <u>Substitute the value of x on the RHS and </u><u>on </u><u>LHS </u>:-

$\sf \implies{f}(“7”) = 10(“7”) + 45$

Simplify the RHS:-

<u>Multiply 10 and 7 :-</u>

$\sf \implies{f}(7) = 10 \times 7 + 45$

$\sf \implies{f}(7) = 70 + 45$

<u>Add 70 and 45 :-</u>

$\sf \implies{f}(7) = 115$

We're done!

Hence, the value of f(7) would be,

$\sf \implies{f}(7) = 115$

$\rule{225pt}{2pt}$

I hope this helps!

Let me know if you have any questions.
