Answer:
The answer to your question is: 11 < pH < 14
Step-by-step explanation:
Data
Bleach have a pH less than 14 and greater than 11.
We have to use these symbols:
< greater than > less than
and pH will be in the middle
11 < pH < 14
This inequality means the Bleach has a pH between 11 and 14
The correct answer is <u><em>(2,−1)</em></u>
If you draw out a rectangle, two opposite sides will be 10 feet and the other two sides we will label as x.
The perimeter of a rectangle is adding up all the sides, so if you add up all those sides you get
x + x + 10 + 10
we know the perimeter is 28 feet, so we know
x + x + 10 + 10 = 28
now we can solve for x
x + x + 10 + 10 = 28
2x + 20 = 28
2x = 8
x = 4
one of the other sides is 4 feet

Answer:
<em>The coordinates of B' are (-3,-15)</em>
Step-by-step explanation:
We are given the point A(-3,-1) and we know it was dilated to the point A'(-9,-3) by some scale factor.
The scale factor can be found by dividing each coordinate of A' by the same coordinate of A. Let's call the factor as k:
k = -9/(-3) = 3
k = -3/(-1) = 3
Thus the scale factor is 3.
If we apply the same factor to B(-1,-5), we get the coordinates of B' as:
B'( 3*(-1) , 3*(-5) ) = B'(-3,-15)
The coordinates of B' are (-3,-15)
