Answer:

(-3,0)

Step-by-step explanation:

The two points that are located on the line y=5 are (-3,5) and (8,5), so the other two points have to be on the same line y=0 because of the y coordinate in (8,0). The shape is a rectangle so the the distance between (-3,5) and (8,5) will be the same as (8,0) and S. So, S has to be at (-3,0).

The graph below shows the distance traveled by a person biking at a rate of 6
Oxana [17]

Answer:

d = 8t

Step-by-step explanation:

Oil that costs 22.50/barrel is mixed with oil that costs 35.00/barrel. How many barrels of each oil should be included in 1250 b
timama [110]
So 22.5 per barrel



so 22.5
x represents the number of 22.5 barrels

y represents the number of 35 barrels

so
x+y=1250

then find the total cost
1250 barrels
27.5 per so mutiply by 1250 and get 34375 total cost

22.5x+35y=34375

we have 2 senctances
x+y=1250
22.5x+35y=34375

elimination
mulitply first equation by -35 to clear y
-35x-35y=-43750
add to second equation
-35x-35y=-43750
<u>22.5x+35y=34375    +</u>
-12.5x+0y=-9375
-12.5x=-9375
multiply -1
12.5x=9375
divie both sides by 12.5
x=750


subsitute
x+y=1250
750+y=1250
subtract 750
y=500


750 barrells of the 22.5 oil should be included and
500 barrells of the 35 oil should be included

Which of the following is a logarithmic function?
Ipatiy [6.2K]

Only a function that actually shows the word "ln" or "log" or "log to the base b" is a log function.


Taking a closer look at #3: y = log 0.25^x, we see that this can be simplified by writing the base (10) as follows: 10 10


and then using y as the exponent of the first 10 and log 0.25^x as the exponent of the second 10:



10^y = 10^(log 0.25^x)


You were not asked to do this, but this discussion may be of interest and help to you down the line.


10^y = 0.25^x
