Answer:
$82.16
Step-by-step explanation:
78.25 * .20 = 15.65 as a tip,
78.25 *.15 = 11.74 as the discount, subtract from initial value:
78.25 - 11.74 = 66.51
then add the tip: 15.65 + 66.51 = $82.16
Answer:
-98
Step-by-step explanation:
Answer:
(1,4)
Step-by-step explanation:
The two lines intersect at 1,4 when you graph them
The first equation is already in slope intercept from, so you know the y-int. is 7 and the slope is 3. However, the second equation must be put in slope int. form.
5x+2y=3
move the y to the other side
5x=3-2y
move the 3 to the other side, so the y variable is by itself
5x-3=-2y
divide by -2 to the equation is equal to y
(-5x/2)+(3/2)=y
you now know the y int. of the second equation is 3/2 and the slope is -5/2
know that you know the slop int. formulas for both equations you can graph them
