The seller must charge a one-time fee:
y=one-time fee
x=profit for each computer part
we would have to compute the following system of equations:
y+16x=$1700
y+56x=$4300
We can solve this system by substitution method
y+16x=$1700 ⇒y=$1700-16x
<span>y+56x=$4300
</span>($1700-16x)+56x=$4300
40x=$4300-$1700
40x=$2600
x=$2600/40
x=$65
we find out the value of "y"
<span>y=$1700-16x
</span>y=$1700-16($65)
y=$1700-$1040
y=$660
if we would sell 30 computers parts the profit would be: 30x+y
profit if the man sells 30 computers parts=30($65)+$660=$2610
answer: his earning will be $2610
Multiplication is when you times two different numbers together where its negative or postive(you can multiple pretty much anything together)but combining like terms are number or letters thats the same. For instance, say if i have 4x+7-2x+3, i would combine each term that has something in common with it,like, 4x and 2x because both has X and i will combine 7 and 3 because those two are regular numbers and does not have an X like the others. I Hope That helps!
Hello.
The answer is: (x−4)(x−6)
Factoring means we want something like
(x+_)(x+_)
We need two numbers that...
Add together to get -10
Multiply together to get 24
Try -4 and -6:
-4+-6 = -10
-4*-6 = 24
Fill in the blanks in
(x+_)(x+_)
with -4 and -6 to get...
(x-4)(x-6)
Have a nice day
