Answer:

Two equation system

80 bracelets

40 necklaces

Step-by-step explanation:

x+y=120

8x+11y=1080

x=120-y

8(120-y) +11y=1080

x=120-y

960-8y+11y=1080

x=120-y

3y=120

x=120-y

y=40

x=120-40

y=40

x=80

y=40

Artemon [7]

Answer:

? = 57

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos ? = adj/ hyp

cos ? = 14/26

Taking the inverse cos of each side

cos ^-1 ( cos ?) = cos ^-1 ( 14/26)

? = 57.42102961

To the nearest degree

? = 57

Compare the functions shown below:

The intersection with the y axis occurs when x = 0.
 We have then:
 
 For f (x):
 
f (0) = -3 (0) - 5&#10;&#10;f (0) = 0 - 5&#10;&#10;f (0) = - 5

 For g (x):
 
We can observe in the graph that when x = 0, the value of the function cuts to the y axis in y = -3

 For h (x):
 
h (0) = 2cos (2 (0) -\pi) +4&#10;&#10;h (0) = 2cos (0-\pi) +4&#10;&#10;h (0) = 2cos (-\pi) +4
 h (0) = 2 (-1) +4&#10;&#10;h (0) = -2 + 4&#10;&#10;h (0) = 2

 Therefore, the graph with the intersection with the largest y axis is h (x)

 Answer:
 
the greatest y-intercept is for:
 
C. h(x)
