100-69.78=30.22-26.73=3.49 the sales tax is 3.49
C is the correct answer.<span />
Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
36p=5p(7.5)
Step 1: Simplify both sides of the equation.
36p=37.5p
Step 2: Subtract 37.5p from both sides.
36p−37.5p=37.5p−37.5p
−1.5p=0
Step 3: Divide both sides by -1.5.
−1.5p
−1.5
=
0
−1.5
p=0
Answer:
(1,0)
(-2,3)
(5,24)
Step-by-step explanation:
To solve this you can can just plug in the x and y values and see which work
y = x²-1
Lets test (0,1):
1 = 0²-1
1 = -1
This pair <em>does not</em> work, because 1 does not equal -1
Lets test (1,0):
0 = 1²-1
0 = 0
This <em>does</em> work, because 0 equals 0
Lets test (3,5):
5 = 3²-1
5 = 9 - 1
5 = 8
This pair <em>does not</em> work, because 5 does not equal 8
Lets test (5,24):
24 = 5²-1
24 = 25 -1
24 = 24
This pair <em>does</em> work, because 24 equals 24
Lets test (-2,3):
3 = (-2)²-1
3 = 4-1
3 = 3
This pair <em>does</em> work, because 3 equals 3
Lets test (-4,-17):
-17 = (-4)²-1
-17 = 16 - 1
-17 = 15
This pair <em>does not</em> work, because -17 does not equal 15
So the pairs that are on the graph are:
(1,0)
(-2,3)
(5,24)
