Step-by-step explanation: Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Rewrite it as y=6x-7/5
Flip the x and y
x=6y-7/5
Solve
5x=6y-7
5x+7=6y
5/6x+7/6=y
f^-1(x)=5/6x+7/6
Answer:
x= -2, y = -2
Step-by-step explanation:
Solve the following system:
{2 y - 4 x = 4 | (equation 1)
{4 x - y = -6 | (equation 2)
Add equation 1 to equation 2:
{-(4 x) + 2 y = 4 | (equation 1)
{0 x+y = -2 | (equation 2)
Divide equation 1 by 2:
{-(2 x) + y = 2 | (equation 1)
{0 x+y = -2 | (equation 2)
Subtract equation 2 from equation 1:
{-(2 x)+0 y = 4 | (equation 1)
{0 x+y = -2 | (equation 2)
Divide equation 1 by -2:
{x+0 y = -2 | (equation 1)
{0 x+y = -2 | (equation 2)
Collect results:
Answer: {x = -2
, y = -2
Hello!
To solve this exercise, let's think a bit and choose the best option for each alternative.
<h2>(a) Karen's desk is about 3...</h2>
Well, a desk with 3mm or 3cm is too small, and with 3km is too big.
In this case, the best option is 3 meters (even though it's big, it's the best option).
<h2>(b) Dan's refrigerator has a mass of 80...</h2>
Usually, a refrigerator is heavy. So the best option is kilograms.
<h2>(c) The bucket holds about 5... of water.</h2>
5ml of water is too little, it fits in a spoon. The correct option is liters.
Answers:
a. meters
b. kilogr
Let C equal bags of cookies
Let M equal money earned
2.75c=m
Probably not enough sorry if it isn't
