13.8 times h times 3.14
*I do not know the number of the height*
5y+8=0 --> 5y = -8 --> y = -8/5
Answer:
The answer to the question provided is -9.
Answer:
3x+4
Step-by-step explanation:
f(x) = - x+4
Substitute in x=-3x
f(-3x)= - (-3x) + 4 = 3x+4
When solving inequalities you want to first group all like terms, so you'd first add 8 to both sides, and get rid of the extra number on the left side.
7x ≤ -7
Then you'd isolate the variable, so you should divide both sides by 7.
<u>x ≤ -1</u>
When graphing the equation the solution set includes -1 so you would put a closed circle (filled in). The variable "x" is less than and equal to -1 so you would put the arrow facing left <----.
