Here is the solution for the eqns.
You are right the one you have highlighted .
Y=-1/2x+3
Answer:
66
Step-by-step explanation:
the order of operations is the acronym PEMDAS which stands for:
P: Parentheses
E: Exponents
M & D: Multiplication and Division
A & S: Addition and Subtraction
we do these in order, from left to right in the equation
for the equation (14 - 8) x (15 - 4), we would start with solving the parentheses
there are 2 sets of parentheses, so we will go from left to right in solving it:
(14 - 8) = 6
(15 - 4) = 11
we replace the values we have found from the parentheses into the equation
6 x 11
now we go through the list
we can already eliminate exponents because there are none in this equation
the next step is multiplication & division, in this equation there is only multiplication, so we multiply 6 x 11 which gives us the answer 66
there is nothing left for us to do at this point, so 66 is our final answer
Answer:
13 nickels and 8 dimes
Step-by-step explanation:
okay, we know that he has $1.45
we know $1= 100 cents.
so we know he has 145 cents
we know one nickel= $0.05
we know one dime=$0.10
we know he has twice as many minuses 3 nickels compared to dimes.
with this information we can make an equation d=dimes n= nickels
145= (5x(n-3)) + (10xd)
we know whatever we plug in for n, d will be half as much. so plug in even numbers that can easily be decided by 2 for n. then take whatever number you put for n and divide it by 2 to get d. for example, if you put 10 for n you would put 5 for d.
eventually you'll end up with an equation that looks like this
145=(5×(16-3))-(10×8)
meaning you have
16-3= 13 nickels
and. 8 dimes
The Phase Shift is how far the function is shifted horizontally from the usual position.
