Anise wants to have longer hair than her sister. Her sister’s hair is 2.25 feet long. How long does Anise’s hair have to be? Which graph represents the scenario? a. A number line going from negative 3 to positive 5. A closed circle is at 2.25. Everything to the right of the circle is shaded.

b. A number line going from negative 3 to positive 5. An open circle is at 2.25. Everything to the right of the circle is shaded.

c. A number line going from negative 3 to positive 5. An open circle is at 2.25. Everything to the left of the circle is shaded.

d. A number line going from negative 3 to positive 5. A closed circle is at 2.25. Everything to the left of the circle is shaded.

d no solution

step-by-step explanation:

$20 bought 16 songs

therefore each song costs $20/16 = $5/4 = $1.25

so:

2 songs would cost 2 * $1.25

3 songs would cost 3 * $1.25

songs would cost x * $1.25

since renata started with $20, then her balance (y) after buying x songs would be:

y = 20 - 1.25*x

well we can use $ left as the y axis and the amount songs purchased as the x axis.   first we are going to divide 20 by 16 to get 1.25 which means that each song is $1.25. *which means after 16 songs on the x axis the lone should be at the bottom at point (0, 0).*   your equation is y=20-1.25x if you need more information just let me know : )

part a.

angle addition postulate:

if a point lies on the interior of an angle, that angle is the sum of two smaller angles with legs that go through the given point.

from the diagram you can see that point w lies on the interior of an angle, then

m∠uvx=m∠uvw+m∠wvx.

answer: correct choice is b.

part b.

substitution property of equality:

if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.

given that xy≅yz and xy=4a+4, yz=20, you can substitute instead of xy the expression 4a+4 and instead of yz the expression 20 into the iquality xy≅yz and obtain

4a+4=20

answer: correct choice is a.
