Answer:

I could be mistaken but I believe that x= 42.5

Step-by-step explanation:

To find this, you solve for 4x+10=180.

This is because the total angle measure of line RD should be 180 degrees.

When you solve this equation, you get 42.5 for X

Using substitution x+3y=3 3y-2x=12

frez [133]

Step-by-step explanation:

Given :-

x + 3y = 3
3y - 2x = 12

And we need to solve the equation using Substituting method . So on taking the first equation ,

$\rm\implies x + 3y = 3 \\\\\rm\implies x = 3 - 3y$

Put this value in (ii) :-

$\rm\implies 3y - 2x = 12 \\\\\rm\implies 3y - 2(3-3y)=12\\\\\rm\implies 3y -6-6y = 12 \\\\\rm\implies -3y = 18 \\\\\rm\implies y = -6$

Put this Value in (I) :-

$\\\\\rm\implies x = 3-3*-6 \\\\\rm\implies x = 3+18 \\\\\rm\implies x = 21$

Hence the Value of x is 21 and y is (-6) .

F(x)=5x^4 helllllpppppp

Marina CMI [18]

we can use properties of functions to find this out

for $f(x)=ax^b$

if b is even, then the ends of the function go in the same directions (both up or both down)

if b is odd, then the ends of the function go in different directions (one up and one down)

if a is positive and b is even, then both ends point up

if a is positve and b is odd, then it goes from bottom left to top right

if a is negative and b is even, then both ends point down

if a is negative and b is odd, then it goes from top left to bottom right

given $f(x)=5x^4$

a=5>0

b=4 which is even

so it has both ends pointing up

bottom right graph is yo answer
