Answer: f(x+3)=x+4

Step-by-step explanation:

f(x)=x+1

f(x+3)=(x+3)+1 ⇔ substitute x

f(x+3)=x+3+1 ⇔ take of parentheses

f(x+3)=x+4 ⇔ simplify

Hope this helps!! :)

Given that f(x) = 6x +1, find (f of)(-2).<br> (f of)(-2)<br> | (Simplify your answer.)
irakobra [83]

Answer:

(f of)(-2) = -65

Step-by-step explanation:

<u>Set up (f of)(-2)</u>

(f o f)(-2) = f(f(-2))

<u>Once you get (fof)(-2) you then have f(#)</u>

f(6(-2) + 1) = f(-11)

6(-11) + 1 = -66 + 1 = -65

Solve y=4x-1 y=3x+6 by substitution brainly
Vesnalui [34]

Our problem becomes 4x-1=3x+6 To solve this, we need to get all of the x's on one side, we are going to subtract 3x to do that. We end up with:

x-1=6

Now we just need to get rid of the -1 and we're home free. We get rid of that -1 we just add one

x=7


Any questions?

Expand and simplify 2(x + 7) + 3(x + 1)
nordsb [41]

Answer:

5x+17<u />

<u />

Step-by-step explanation:

We will have to expand first then we simplify.

<u>Expand</u>

You will have to distribute the 2 over the x & 7 and the 3 over the x & 1 respectively.

<u />2(x+7)+3(x+1)=2x+14+3x+3<u />

<u>Simplify</u>

You will have to add 2x & 3x together and 14 & 3 together.

<u />2x+14+3x+3=5x+17<u />

<u>Answer</u>

<u />5x+17<u />

Two angles of a triangle have the same measure and the third one is 33 degrees greater than the measure of each other two. Fine
gavmur [86]

ill try my best

Add the two angles you already know (for example, 50 and 45), then, with the sum of the two angles (95), subtract it from 180 (180-95) and there's your answer. How do I find the third angle of a triangle if the two known angles are 35 and 40?

The measure of any exterior angle of a triangle is equal to the sum of the measures of its two interior opposite angles. The sum of the three angles of a triangle is 180°. ... The sum of the lengths of any two sides of a triangle is always greater than the length of the third side.

all i got (:
