<em>f(-5) = 15 (A)</em>
- Step-by-step explanation:
<em>f(x) = - 2x + 5</em>
<em>replace x = - 5</em>
<em>f(-5) = -2(-5) + 5
</em>
<em>(-)(-) = +
</em>
<em>f(-5) = 10 + 5
</em>
<em>f(-5) = 15 (A)</em>
If Terri had 5 blouses and 3 pairs of pants, Teri could wear 15 different combinations of clothes. 1 blouse can be worn with any of the three pairs of pants, as for the other 4. 5 * 3 = 15. The answer is 15 combinations.

Answer:
Two semi circles would equal one circle.
The perimeter of a circle is PI x diameter.
The diameter of the circle is shown as 56 m
The perimeter of the 2 ends = 56 x 3.14 = 175.84
The length of the inside of the track is given as 130 m, and there are 2 sides so 130 + 130 = 260 m.
Total perimeter = 260 + 175.84 = 435.84 m.
Step-by-step explanation:
y = | x -5| + |x+5|
as range of x is
-5 < x < 5
we can see if we put x = 0 we get
y = 10
we put any value of x in given range first term is always negative without absolute. and 2nd term is always positive
so
y = | x -5| + |x+5|
= -( x-5) + x + 5
= - x + 5 + x + 5
= 10
so
y = 10 where -5 < x < 5
