-6(a+8)
= (-6)(a+8)
= (-6)(a)+(-6)(8)
Your final answer would be -6a - 48!
The range would be [8, 3]
In order to find the range, simply plug each end of the domain into the equation.
f(x) = -x + 5
f(-3) = -(-3) + 5
f(-3) = 3 + 5
f(-3) = 8
Then the other side
f(x) = -x + 5
f(2) = -2 + 5
f(2) = 3
Suppose you roll a red number cube and a blue number cube. What is the probability that you will roll a 5 on the red cube and a 1 or 2 on the blue cube?
Answer:
pizza: $4, coke: $3, chips: $2
Step-by-step explanation:
Lets make the price of a pizza=p a coke= k and a bag of chips=c
then we have the following equations
p+k+c=9
p+2k=10
2p+2c=12
Because p is common in all the equations we shall make it the subject of each equation.
p=9-(k+c)...........i
p=10-2k..............ii
p=6-c...................iii
We then equate i and iii
9-(k+c)=6-c
9-k-c=6-c
putting like terms together we get:
9-6=-c+c+k
1 coke, k=$3
replacing this value in equation ii
we get p=10-2(3)
p=10-6= 4
1 pizza, p=$4
replacing this value in equation iii
4=6-c
c=6-4
=2
a bag of chips, c=$2
Thus, a pizza, a coke and a bag of chips= pizza: $4, coke: $3, chips: $2
A note book costs 3$ (Then the pen costs 1$ as a bonus:P) 3+3+1=7 and 3+1+1+1+1+1=8 Hope that helps:)
