M = 4, 1. 5=5m+2m-23 2. 5=7m-23 3. 28=7m 4. m=4. The first step is just me rewriting the problem so that like terms are right by each other. On the left side I added the like terms, 5m and 2m. That equals 7m. Now, looking at the second step. To get rid of the -23 on the left side, we add 23 to it which cancels it out. We have to add 23 on the other side too. So, 5+23 is 28. This brings us to step 3. 7m divided by 7 is M. And 28 divided by 7 is 4. This leaves us with the answer m=4.

∠EFG and ∠LMN are supplementary angles, m∠EFG=(3x+17)º, and m∠LMN=(12x−5)º.
Ira Lisetskai [31]

Answer:

EFG = 50.6, LMN = 129.4

Step-by-step explanation:

ok so s supplementary angles mean, their angles will always add upto 180. for example if one angle is 100° then the other will be 80°.

to find the angles first we need to solve for x.

we know EFG + LMN = 180 because its supplementary.

that's is (3x+17) + (12x-5) = 180.

we now solve for x;

15x+12 = 180

15x = 168, x= 168/15 = 11.2

now that we know x we can put this value in the corresponding equation of EFG and LMN to find the angles.

EFG = 3x11.2 + 17 = 50.6

LMN = 12x11.2 - 5 = 129.4

F(x) = x2. What is g(x)?
ahrayia [7]

Answer:

Answer: g(x)=. Step-by-step explanation: We are given that: f(x)=x². We have to find g(x). Since, we are given that g(3)=1. Hence, we will ...  ·  g of x would equal (1/3x)^2 because if x was 6 y, g(x), would be 4
