Graph each absolute value function. State the domain, range, and y-intercept.
grandymaker [24]

Answer:

i) D: All real numbers

ii) R: y\le5

iii) Y-int: b=2

Step-by-step explanation:

i) The given absolute value function is

y=-|x+3|+5

The domain is all values of x that makes the function defined.

The absolute value function is defined for all values of x.

The domain is all real numbers.

ii) The given function is y=-|x+3|+5

The function has vertex (-3,5).

The function is reflected in the x-axis.

This means the vertex is the maximum point on the graph of the function.

The maximum y-value is 5.

The range is therefore y\le 5 or (-\infty,5]

iii) To find the y-intercept, put x=0 into the function.

y=-|0+3|+5

y=-|3|+5

y=-3+5

y=2

The y-intercept is (0,2) or b=2

See attachment for graph.

Panchito needs to make 80 ml of a 39% alcohol solution. He is going to make it by mixing a 50% alcohol solution with a 6% alcoho
devlian [24]

Answer:

60ml of the 50% alcohol solution  and 20ml of the 6% alcohol solution

Step-by-step explanation:

We can build a system of equation for solve this problem

x = first solution

y = second solution

x + y = 80

0.5x + 0.06y = 80 * 0.39

x + y = 80

0.5x + 0.06y = 31.2

x = 80 -y

0.5(80-y) + 0.06y = 31.2

40 - 0.5y + 0.06y = 31.2

-0.44y = -8.8

y = 20

x = 80 - 20 = 60
