Answer:
75
Step-by-step explanation:
f(x)=-x^2-10x
f(-5)=(-5)^2-10(-5)
f(-5)=(-5)(-5)+50
f(-5)=25+50
f(-5)=75
Answer: 5-2x=6-x, x= -1/3
Explanation:
“When I double it and subtract it from five it is the same as subtracting it from six”
So double means multiply by two, and the same as means equal. Use a variable to represent the number.
Therefore your equation is:
5-2x=6-x
So solving the equation would be:
-2x-x = 6-5
-3x = 1
x= -1/3
