Answer:

15m^3-26m^2+11m-4

Step-by-step explanation:

Find the product

(5m^2 - 2m + 1)(3m - 4)

Multiply both the parenthesis. Multiply each term inside the second parenthesis

5m^2 *3m + 5m^2*(-4) =15m^3-20m^2

-2m * 3m + (-2m)(-4)= -6m^2 +8m

1*3m +1(-4)=3m-4

Collect all the terms together

15m^3-20m^2 -6m^2 +8m+3m-4

Combine like terms

15m^3-26m^2+11m-4

Answer:

y = 4; g(7) = 4

Step-by-step explanation:

The meaning of g(7) is wherever you see an x in g(x) you put a 7. In this case you are being told that x = 7

So go to 7 on the x axis, go up until you hit the blue line which is g(x) and then read what it says on the y axis. It shows 4 and that is your answer.

The Fruitz fruit and vegetable shop is selling grapes at a price which is 10% cheaper than the Happy Fruiterer fruit and vegetab
sdas [7]

Answer:

(a) It costs $55 at Happy Fruiterer

(b) It will cost $49.64

(c) It is cheaper at Happy Fruiterer the second week

Step-by-step explanation:

Since Fruitz shop sells as 10% less than Happy Fruiterer at $50

10% more of $50 = 50 × 10/100 + 50

= $5 + $50 = $55

(a) n Kg of grapes will cost $55 at Happy Fruiterer

(b) if Happy Fruits discounts $55 by 5%, we will have

55 × 5/100 = 2.75

that is $55 - $2.75 = $52.25

If it is discounted further at 5% more the following week, we will have

$52.25 × 5/100 = $2.6125

≈ $2.61

Then the new price for the 2nd week is $52.25 - $2.61

= $49.64

(c) at the second wee of discounting, Fruitz shop still sells at $50 will Happy Fruiterer now see at $49.64. Therefore, it is cheaper at Happy Fruiterer
