Answer:
The blue point will be at (4, 3)
Step-by-step explanation:
Numbers inside the parenthases only affect x, but are revered. If it is -4, move right 4. lf it is 4, move left 4.
Numbers after the patentheses affect the movement of y. When the point is at (4, 0), move up 3.
Answer:
220 candy bars
Step-by-step explanation:
Let the number of candy bars sold=c
Let the number of fruit snacks sold=f
A total of 650 items were sold.
Candy bars are sold for $2.50
Fruit snacks are sold for $1.50
Total Income =$1,195
- Therefore: 2.5c+1.5f=1195
We solve the resulting system of equation for c, the number of candy bars sold.
From the first equation, f=650-c
Substitute f=650-c into 2.5c+1.5f=1195
2.5c+1.5(650-c)=1195
2.5c+975-1.5c=1195
Collect like terms
2.5c-1.5c=1195-975
c=220
Therefore, 220 candy bars were sold.
The correct answer is: [A]: " 4x³ + x² − 11x + 15 " .

<u>Note</u>:
_______________________________________________________
(6x³ − 4x + 5) − (2x³ − x² + 7x − 10) ;
= (6x³ − 4x + 5) − 1(2x³ − x² + 7x − 10) ;
_________________________________________
Examine the following portion of the expression:
_________________________________________
" − 1(2x³ − x² + 7x − 10) " ;
= (-1 * 2x³) − (-1 * x²) + (-1 * 7x) − (-1 * 10) ;
= (-2x³) − (-1x²) + (-7x) − (-10) ;
= (-2x³) + 1x² − 7x + 10 ;
= " − 2x³ + 1x² − 7x + 10 " ;
Now, bring down the other part:
6x³ − 4x + 5 − 2x³ + 1x² − 7x + 10 ;
Combine the "like terms" :
6x³ − 2x³ = + 4x³ ;
− 4x − 7x = − 11x ;
+ 5 + 10 = + 15 ;
and bring down the:
+ 1x² ( which equals: " x² ") ;

And rewrite:
____________________________________________________
→ " 4x³ + x² − 11x + 15 " ;
→ which is: Answer choice: [A]: " 4x³ + x² − 11x + 15 " .

Let
represent the number of hard drives produced.
The first thing we need to do is convert 10 cents to dollars:
. Now, we know that the the cost of materials is 30 dollars and the cost of labor is 0.1 dollars, so the total coast to produce
hard drives will be:
.
Now the only thing left is add t<span>he cost of equipment to complete our function:
</span>
We can conclude that the equation that could represent the cost function for making x hard drives is <span>
f(x)=30.1x+10,000</span>
