Answer:
x > -35
Step-by-step explanation:
When Janet got rid of the 4, she added it to -3 instead of subtracting 4.
So, the next step should look like this:
> -7
Then, multiply both sides by 5.
x > -35
This is the correct way of solving for x in this inequality.
Answer:
the range is all real numbers greater than or equal to -4.
Step-by-step explanation:
this is because the range of the function's lowest point is -4, including -4. therefore, the range is all real numbers greater than or equal to -4.
Answer:
8
Step-by-step explanation:
if we do 128+7.95 we get 135.95. but when we do 128+8(wich is 6.25% of 128) we get 136. so she will pay 8 dollars in shipping
Hope this helps.
A.
continuious means they both approach the same number as they approach 1
basically, find the vallues of q in terms of p for which both of them equal 1
so
1+2p(1-1)+(1-1)^2=1 (this simplifies to 1=1 so don't mess with the p)
q(1)+p=1, q+p=1, q=1-p
the value of q that will make it continous at x=1 is 1-p
B. find the values of p and q such that their derivitives are equal at x=1
first one's derivitive:
2px+2x-2, at x=1, 2p+2-2=2p
2nd one's derivitive:
q
so
2p=q
from the value in part a
q=1-p
2p=1-p
add p to both sides
3p=1
divide by 3
p=1/3
q=1-1/3
q=2/3
the function is
1+(2/3)(x-1)+(x-1)^2 for x≤1 and
(2/3)x+(1/3) for x>1
C. take the derivitive twice to get
0 and
0
both same deriritive
find if they have the same value
well, 0=0
yes
A. q=1-p
B. p=1/3, q=2/3
C. yes, both have value of 0 and change of slope is 0
