Answer:
+8
Step-by-step explanation:
this is because when a negative multiplies with another negative it becomes positive
He has to wait 13 minutes for the 7:18 train
To get the average you need to add all the numbers together and divide by the match number. So, 98+25+105+62+65=355. 355/5=71, therefore the average is 71
F(x) = 1, so we make the entire equation equal 1.
1 = sqrt(x) + 7
To make x by itself subtract 7 from both sides
-6 = sqrt(x)
Square both sides to remove sqrt from x.
36 = x
The value of x is 36
Answer:
13
Step-by-step explanation:
Since we want to find f(x) when x equals 10, we can substitute 10 in for x
f(x)=x/2 +8
f(10)=10/2+8
Divide 10 by 2
f(10)=5+8
Add 5 and 8
f(10)=13
So, f(x) when x=10 is 13
