Answer: Choice C
The solution is
The graph has an closed filled in circle at 8 on the number line, with shading to the right of that closed circle.
=======================================================
Explanation:
see note below
note: I divided both sides by -4 to undo the multiplication done to z; the inequality sign flips because we divided both sides by a negative number
So the solution set is the set of z values such that z is 8 or larger. We are including the endpoint 8 so we use a filled in closed circle (not an open circle or hole). We include the endpoint because of the "or equal to" as part of ht inequality sign.

Answer:
468
Step-by-step explanation:
If the first term of a geometric series and the common ratio are known, then the sum of the infinite series is
a
s = --------------
1 - r
In this particular case we have:
156
s = -------------- = 156/(1/3) = 468
1 - 2/3
Answer:
a)4x ≤30 where x is the quantity of muffins b) The greatest amount of muffins you can purchase is 7. c) 2dollars
Step-by-step explanation:
a) 4x ≤30 where x is the quantity of muffins
b) 4x≤30
x≤7.5
It means that you can buy only 7.5 muffins or less. But you can buy only whole muffin, so you can buy 7 muffins or less. The greatest amount of muffins you can purchase is 7.
c) If you purchase 7 muffins you spend 7*4= 28 dollars
And then you will have 30-28=2dollars
U gotta use pythagorean theory
So a^2 +b^2 = c^2
C=7 since its the one facing the right angle
5.2^2 + b^2 = c2
27.04 +b^2= 49
Subtract 21.96 from both sides, so ur left with 21.96=b^2
Under the square root and rounded up would equal 4.7
Hope this helps
