Dorian buys 2 pounds of almonds for $21.98 and 3 pounds of dried apricots for $26.25. Which is less expensive per pound? How muc
ozzi

Answer:

The apricots are less expensive per pound.

Step-by-step explanation:

Cost of 1 pound of almonds = 21.98/2

Cost of 2 pounds of almonds = $21.98

So then you have to do 21.98 - 21.98/2. Which equals $10.99

Cost of 1 pound of dried apricots = 26.25/3

Cost of 3 pounds of dried apricots = $26.25

So then you have to do $26.25 - 26.25/3 which = $17.5 then divide that by 2 which equals $8.75.

To find out how much less expensive you have to find the difference, so to do that you have to do $10.99 - $8.75 = $2.24 per pound less expensive.

Which function is represented by the graph? f(x) = –|x| 4 f(x) = –|x| – 4 f(x) = –|x 4| f(x) = –|x – 4|.
exis [7]

The function which is represented by the graph attached below shifted 4 units right is similar to option d, which is,

f(x)=-|x-4|

<h3>What is a graph of function?</h3>

The linear function has the highest power of the unknown variable one. Thus, the graph plotted for the linear function is a straight line.

Types of function movement over the graph -

  • Horizontal shift- Let the parent function is f(x). Thus by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.
  • Vertical shift- Let the parent function is f(x). Thus by replacing parent function with f(x)-c shifts the graph b units down and by replacing parent function with f(x)+cshifts the graph b units up.

The graph given in the problem is attached below. All the parents function of the options are absolute function.

In the graph, the parent function 4 units shifted to right. So the -4 should add in the parent function. Thus, by the above definition, this is a horizontal shift of the function and can be written as,

f(x)=-|x-4|

Hence, the function which is represented by the graph attached below shifted 4 units right is similar to option d, which is,

f(x)=-|x-4|

Write the algebraic expression that matches each graph
Sophie [7]

Answer:

1. y= |x| -15

2. y = -|x| +3

Step-by-step explanation

.The V shape means absolute value (the | | ), since its upside down, the equation has to be negative. The tip of the V doesn't start at 0 like normal, it's up 3, so the equation has a +3 at the end. The x intercept at (3, 0) is just so you can check your work. If we plug in 3 for x, we do in fact get 0 for y.

Not sure, if correct but here.

Dwayne has $5.00 kendra has 1/10 as much money as dwayne juan has 1/10 as much money as kendra tom has 10 times as much money as
Paha777 [63]
To answer this question you need to interpret the ratio of the money correctly. We only know Dwayne money, so it's better to solve the ratio which was related to Dwayne. In this case, it was Kendra or Tom. 

Dwayne money = $5
Kendra money= 1/10 Dwayne money= 1/10 x $5= $0.5
Juan money= 1/10 Kendra money = 1/10 x $0.5= $0.05
Tom money = 10 x Dwayne money = 10 x $5 = $50
Ruth money = 10 x Tom money = 10 x $50= $500
