To find this out, lets find out how much one mouse cost:
Divide the cost by the number of mice:
8.35/5 = 1.67
Then multiply it by 2, the hypothetical number of mice sold:
2 x 1.67 = 3.34
So the final answer is $3.34
Hope this helps!
Answer:
The legs are A and B
Step-by-step explanation:
Question 21
Let's complete the square
y = 3x^2 + 6x + 5
y-5 = 3x^2 + 6x
y - 5 = 3(x^2 + 2x)
y - 5 = 3(x^2 + 2x + 1 - 1)
y - 5 = 3(x^2+2x+1) - 3
y - 5 = 3(x+1)^2 - 3
y = 3(x+1)^2 - 3 + 5
y = 3(x+1)^2 + 2
Answer: Choice D
============================================
Question 22
Through trial and error you should find that choice D is the answer
Basically you plug in each of the given answer choices and see which results in a true statement.
For instance, with choice A we have
y < -4(x+1)^2 - 3
-7 < -4(0+1)^2 - 3
-7 < -7
which is false, so we eliminate choice A
Choice D is the answer because
y < -4(x+1)^2 - 3
-9 < -4(-2+1)^2 - 3
-9 < -7
which is true since -9 is to the left of -7 on the number line.
============================================
Question 25
Answer: Choice B
Explanation:
The quantity (x-4)^2 is always positive regardless of what you pick for x. This is because we are squaring the (x-4). Squaring a negative leads to a positive. Eg: (-4)^2 = 16
Adding on a positive to (x-4)^2 makes the result even more positive. Therefore (x-4)^2 + 1 > 0 is true for any real number x.
Visually this means all solutions of y > (x-4)^2 + 1 reside in quadrants 1 and 2, which are above the x axis.
Answer:
<em>Choice C is correct because -4 + 4 = 0 as required.</em>
Step-by-step explanation:
<u>Addition and Subtraction</u>
The number line shown in the image indicates the integer +4.
We need to find a number that added to 4 results in 0.
Choice A is not correct because 4 + 4 = 8
Choice B is not correct because -1/4 + 4 = 15/4
Choice C is correct because -4 + 4 = 0 as required.
Choice D is not correct because 1/4 + 4 = 17/4
A cause 4 divide by 5 is .8 and 6 divide by 5 is 1.2
