Answer:

f(2)  = (-2)

Step-by-step explanation:

f (x) = 5x -12

f(2) = 5 * 2 - 12

      = (-2)

Solve for y <br> 5y-x=10<br><br> Is it 2?
svet-max [94.6K]
5y-x=10
Isolate the variable
add x to both sides
5y-x+x=10+x
5y=10+x
Divide both sides by 5
5y/5=10+x/5
y=2+1/5x 
So y is equal to 2+1/5x

A bacteria cell splits into two cells every hour. Write and evaluate an exponential expression to find how many cells there will
ryzh [129]
Easy

equation is
f(x)=2ˣ

where x=number of hours elapsed

after 6 hours
f(6)=2⁶=64 bacteria


to solve for 1024

1024=2ˣ
take ln of both sides
ln(1024)=ln(2ˣ)
ln(1024)=x(ln(2))
divide both sides by ln(2)
ln(1024)/ln(2)=x
using calculator
10=x

or you could recognize that
1024=2¹⁰
or keep divising 1024 by 2


10 hours for 1024 bacteria

I need help ASAP!!!!
mrs_skeptik [129]

Answer:

Step-by-step explanation:

the shape is made up of 2 circles and one box add the 3 areas up

circle area = \pir^{2}

3.14*4^{2} = 50.24

50.24*2 =100.48

box, box,  pit now  :P  ooh I was thinking formula one racing,  ( i've been watching that lately)  anyway

box = 8*8 = 64

total = 164.48  is that an option? hmm, yes the bottom two choices.. now the perimeter .  the perimeter is made up of the 2 circles

the circumference of a circle is 2\pir

2*\pi*r

2*\pi*4 =25.1327    that's one whole circle , multiplied by 2 , I can see , by math in my head that's about 50.26

sooo

the 3rd choice looks good  :)
