Answer:
(1 , 27)
Step-by-step explanation:
The ordered pair (1 , 27) means:
x = 1
y = 27
Now putting value of x and y in given equation to check weather it satisfies:
y = 12x + 15.
27 = 12 (1) + 15
27 = 12 + 15
27 = 27
hence proved

The price after the discount was $45.
When the sporting goods store bought the snowboard and marked it up by 25%, the price became:
<em>= Original cost x ( 1 + markup percentage)</em>
= 120 x ( 1 + 25%)
= 120 x 1.25
= $150
The snowboard was then discounted by 70%, the new price becomes:
<em>= Current price x ( 1 - discount rate)</em>
= 150 x ( 1 - 70%)
= 150 x 30%
= $45
In conclusion, the price after the discount was $45.

The gradient is 3/7 make y the subject. Then put the coordinates in the equation.
Step-by-step explanation:
We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:

b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15
Using the values, we get:
