Answer:
omg that one is hard but it is 18j-6m
Subsitution
solve for y in first equation
add 2x to both sides
y=2x+8
sub 2x+8 for y in second equation
16+4x=2(2x+8)
divide both sides by 2
8+2x=2x+8
true
there are infinite solutions for x
therefor infinite soltions for y
there are an infinite number of solutions
Answer:
-21
Step-by-step explanation:
1-2+4-8+16-32
=-21
Answer: Yes it is a function
Step-by-step explanation:
<em><u>The average would be 16.</u></em>
To calculate this, add all the values together then divide that sum by the amount of data values.
11+16+15+22=64
64÷4=16
