Answer:
See below.
Step-by-step explanation:
For y = a(x - b)^2 + c , the vertex is at (b, c) and the axis of symmetry is x = b.
So for y = (x-2)^2 - 2,
the vertex is (2, -2) and the axis of symmetry is x = 2.
Answer:
Number of roast beef sandwiches bought = 5
Step-by-step explanation:
Cost of a roast beef sandwich = $6.75
x = number of roast beef sandwiches bought
Amount Used for Payment = $50
Change Received = $16.25
Actual amount paid = Amount Used for Payment - Change Received
= $50 - $16.25
= $33.75
Actual amount paid = $33.75
Number of roast beef sandwiches bought = Actual amount paid / Cost of a roast beef sandwich
= $33.75 / $6.75
= 5 roast beef sandwiches
Number of roast beef sandwiches bought = 5
Answer:
9°
Step-by-step explanation:
In a ∆, equal sides make equal angle to the third side. So the angle that's not mentioned is same '2'.
Sum of angles in a ∆ = 180°
80° + m/_2 + m/_2 = 180°
80° + (5x + 5) + (5x + 5) = 180°
10x + 90° = 180°
10x = 90°
x = 9°
Answer:
1/3
Step-by-step explanation:
Left over pie=5/8
Payton eats=1/8 of the left over pie
Joy eats =1/6 of the left over pie
Total pie eaten by Payton and joy= 1/8+1/6
To add the fraction,
Find the lowest common multiple of 6 and 8 which is 48
Then,
divide 48 by 8 multiplied by 1 which is 6,
divide 48 by 6 multiplied by 1 which is 8
We have,
=6+8/48
=14/48
=7/24
Total pie eaten by Peyton and joy=7/24
Total pie left(after Peyton and joy share)= Total left over- total pie eaten by Peyton and joy
=5/8-7/24
=15-7/24
=8/24
=1/3
