Answer:
0
Step-by-step explanation:
(-4,0) and (3,2)
m1=(2-0)/(3+4)=2/7
y=2/7x+b1, using point (-4,0) to find b1 (substitute x=-4 and y=0 in the form)
0=2/7*(-4)+b1 ⇒ b1= 8/7
-----
(-3,2) and (4,0)
m2=(0-2)/(4+3)= -2/7
y= -2/7x+b2, using point (4,0) to find b2 (substitute x=4 and y=0 in the form)
0= -2/7*4+b2 ⇒ b2=8/7
----
m1b2+m2b1= 2/7*8/7 -2/7*8/7=0
Answer:
8 m3
Step-by-step explanation:
Since Box A has a volume of 64 cubic meters, that means each side length is 4 m3. It says to make Box B, they divided these lengths by 2. With that info, you get 8 as your volume
Answer: So, your relative takes N tablets each 6 hours. a day has 24 hours, and 24/6 = 4, so he takes N tablets 4 times per day, so he takes 4*N tablets.
each tablet has 200mg, and 2.3 g (or 2300 mg) is toxic.
this means that 4*N*200mg must be less than 2300, if we are seeking for the maximum N possible, then:
4*N*200mg = 2300mg
4*N = 2300/200 = 11.5
N = 11.5/4 = 2.87
if you round up this number, you will end up taking more than 2.3g of tylenol per day, this implies that N must be equal to 2.
So your relative needs to take maximum 2 tablets per day.
Let
n-------> the number of nickels
q------> the number of quarters
we know that
so
----> equation A
----> equation B
substitute equation B in equation A
![0.05n+0.25[3n]=1.60](https://tex.z-dn.net/?f=0.05n%2B0.25%5B3n%5D%3D1.60)
Find the value of q
therefore
<u>The answer part a) is</u>
the number of nickels are 
and the number of quarters are 
<u>the answer Part b) is</u>
The expressions that represents the number of quarters is
Answer:
the slope is 5
Step-by-step explanation:
f(x) = 5x
f(8) = 5(8) = 40 (8,40)
f(7) = 5*7 = 35 ( 7,35)
the slope is 5
