Anytime you have these slope questions read the graph like you’re reading a book: from left to right. When you read this graph from left to right, it declines so we know that its negative. Now, remember y=mx+b. Our sign is negative and intercepts at -3. All answer choices are at -3, but the answer would be B because as it declines its lesser than.
The correct answer is option B that is Each white blood cell contains millions of haemoglobin molecules. All blood cells come from one pool of stem cells.

II. In a sample of blood, there are more red blood cells than white blood cells.
III. HIV destroys red blood cells.
IV. All blood cells come from one pool of stem cells.
A. II and IV only
B. I and IV only
C. II and III only
D. I, III, and IV only
E. I, II, and IV only
<h3>What are blood cells?</h3>

4 large drinks
The pizza cost $13.00
$6.00 gift certificate
d= cost of one drink
equation
4d + 13 - 6 = 13.20
4d + 7 = 13.2
4d = 6.2
d = 1.55
answer
the cost of one large drink is $1.55
24 to the power of 4
24x10x10x10x10 = 240,000

Here is the method for solving that equation:
Step #1: Write the equation:
-15x = 0
Step #2: Divide each side of the equation by -15 :
<u>x = 0</u>
