At x=-4,, that is where y=0 and y has to be positive

that is where the slope of graph changes, because that is the vertex
so basically we flip the graph at x=-4

it is positive for x>-4
fliped for x<-4

so basically graph
y=x+4 in x<-4
y=-x-4 in x<-4

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 3 large boxes and 5 small boxes has a t

Vinil7 [7]

Answer:

You can not tell unless you have information about the relationship between the small and large boxes (for example, a large box is 2 times the weight of a small box) You can only tell that a small box and a large box's weight together is 34.5 kilograms.

Step-by-step explanation:

3L + 5S = 135

9L + 7S = 279

12L + 12S = 135 + 279

12(S+L) = 414

S+L = 34.5

The bottom part of this block is a rectangular prism. The top part is a square pyramid. You want to cover the block entirely wit

yaroslaw [1]

Answer:

Total paper required = 165 cm²

Step-by-step explanation:

Paper required to cover the entire block = (Surface area of the prism at the base - area of the top of the prism) + Lateral surface area of the pyramid

Surface area of the rectangular prism = 2(lb + bh + hl)

(here l, b, h are the length, width and height respectively)

= 2(5×5 + 5×4 + 4×5)

= 2(25 + 20 + 20)

= 2×65

= 130 cm²

Area of the top of the prism = (side)²

= 5²

= 25 cm²

Lateral area of the square pyramid = 4 × Area of one lateral side

= 4 × $[\frac{1}{2}(\text{Base})(\text{Height})]$

= 4 × $[\frac{1}{2}(5)(6)]$

= 60 cm²

Total paper required = (130 - 25) + 60

= 105 + 60

= 165 cm²
