Blue cassettes hold 45 minutes of music. Green cassettes hold 55 minutes of music. If Niko has 16 cassettes containing 830 minut
Aneli [31]
B + g = 16.....b = 16 - g
45b + 55g = 830

45(16 - g) + 55g = 830
720 - 45g + 55g = 830
-45g + 55g = 830 - 720
10g = 110
g = 110/10
g = 11 <=== there are 11 green cassettes

b + g = 16
b + 11 = 16
b = 16 - 11
b = 5 <=== there are 5 blue cassettes

What is the greatest common factor of 42a5b3, 35a3b4, and 42ab4? 7ab3   6a4b 42a5b4 77a8b7
lbvjy [14]

The <em><u>correct answer</u></em> is:

7ab³

Explanation:

The greatest common factor is the largest thing that each term is divisible by.

The coefficients of our terms are 42, 35 and 42.  Using the prime factorization for each,

42 = 6*7

6 = 2*3

42 = 2*3*7

35 = 5*7

The greatest common factor is 7.

For the variables, each term has at least a¹ and at least b³.  This means that ab³ is part of the GCF; this gives us a GCF of 7ab³.

Graph each absolute value function. State the domain, range, and y-intercept.
Inessa05 [86]
Answer:

i. D:All real numbers

ii.R:y\le-2

iii. Y-int: b=-2.5

Step-by-step explanation:

The given function is

y=-\frac{1}{2} |x-1|-2

The domain of this function are the values of x that makes the function defined.

The absolute value function is defined for all real values.

The domain is all real numbers.

ii. The range refers to the values of y for which x is defined.

y=-\frac{1}{2} |x-1|-2

The vertex of this function is

(1,-2)

The function is reflected in the x-axis.

The vertex is therefore the maximum point on the graph of the function.

The range is therefore;

y\le-2

Or

(-\infty,2]

iii. To find the y-intercept, we substitute x=0 into the funtion.

y=-\frac{1}{2} |0-1|-2

y=-\frac{1}{2} (1)-2

y=-2.5

The y-intercept is b=-2.5

The graph is shown in the attachment.
