Answer:
f(-5)=-125
Step-by-step explanation:
we have

To factor it completely you first look at the first term, if the a term is 1 then your good if it is not you need to divide it by whatever number to make the a term 1, in the first question the a term is just x^2 so it's good. Then,you focus on the b and c term, you have to find multiples of term C that adds up to term b. Going back to problem 1, c is 16 and b is 10. So the two factors would be 8 and 2,because 8×2=16 and 8+2=10. the final step is to put into the proper format,
(x+2) (x+3), which would be considered completely factored.
Answer:
Look at the explanation.
I'll be online so let me know if you still need help.
Step-by-step explanation.
A system of equations is basically two or more equations that rely on each other. If a solution for a variable is 2, it has to work for the other equation.
The substitution is basically plugging in the y value to y = 8x + 10
If y = 2
and also y = 8x + 10
What do you think the substitution is?
The equation would be
x - 18 = collection left
X = how much was your collection before you gave your brother 13 cards
Since we don't know how big was your collection before, this would be the equation to solve it.
Answer:
151
Step-by-step explanation:
Given the following scores
132,140,130,190,112,200,185, 172,163,151,149 . What isn’t the median ?
Median can be gotten whenever we arrange a set of scores in ascending or descending order.
Arranging the above scores in the ascending order, we have
112,130,132,140,149,151,163, 172,185,190 and 200
Median = 151
