Answer:
The solution would be (-19, 40)
Step-by-step explanation:
In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.
5x + 2y = 15
5x + 2(-3x - 2) = 15
5x - 6x - 4 = 15
-x - 4 = 15
-x = 19
x = -19
Now that we have the value of x, we can find the value of y.
y = -3x - 3
y = -3(-19) - 3
y = 43 - 3
y = 40
To find out how much Stan is paid a day, simply find out how many miles Stan drives per day, and multiply that with the amount Stan is paid per mile (in this case $3.50 per mile). Then, add that with the daily amount Stan earned (which is $75).
For example, on Monday, Stan drove a total of 30 miles (and he's paid $3.50 per mile).
Simply multiply $3.50 (per mile) with 30 (total number of miles driven), and that should equate to $105 earned for driving a total of 30 miles.
Then, add $105 (earned from driving 30 miles) to $75 (daily pay) and that equals $180.
Stan had been paid a total of $180 on Monday.
well the x would be 2 and the y would be 25 i think
Answer: (-4,-2)
Step-by-step explanation:
Looking at the graph, if you move from the zoo downwards for 7 units, you will arrive at point B which is also 2 units from the park.
Point B is therefore the doctor's office and its coordinates are, (-4, -2)
Answer:
There are no solutions
Step-by-step explanation:
2(x+1)=2x+5
Distribute the values on the left:
2x+2=2x+5
subtract 2x from each side
2x(-2x)+2=2x(-2x)+5
2=5
These value are not equal so there are no solutions
