Answer:
Equation for the skating palace
= 6 + 2x
Step-by-step explanation:
Let the number of hours = x
For skating palace, the equation is written as:
The slating palace charges a $6.00 shoe rental fee plus $2.00 an hour to skate.
$6 + $2 × x
= 6 + 2x
For Mathland , the equation is written as:
Mathland skating rink charges $4.00 an hour to skate .
$4 × x
= 4x
Therefore, the equation that represents the situation on the skating palace is :
6 + 2x
Answer:
see below
Step-by-step explanation:
To find the x- and y-intercepts, set each of the variables to zero and solve for the other:
y-intercept: 0 +4y = 12 ⇒ y = 12/4 = 3
x-intercept: 3x +0 = 12 ⇒ x = 12/3 = 4
Plot these points (0, 3) and (4, 0), and draw a straight line through them.
Answer:
for x=+1 , y=3
for x=-1 , y=-3
Step-by-step explanation:
y=3x and x^2+y^2=10
y^2=9x^2
x^2+9x^2=10
10x^2=10
x^2=1
x=1 and x=-1
for x=1 , y=3x that means y=3
for x=-1 , y=3x that means y=-3
Answer:
Step-by-step explanation:
l(x) - m(x) = 5x² - 7y² + 4xy - [ -10x² + 9y² - 12xy + 4]
= 5x² - 7y² + 4xy + 10x² - 9y² + 12xy - 4
= 5x² + 10x² - 7y² - 9y² + 4xy + 12xy - 4 {Combine like terms}
= 15x² - 16x² + 16xy - 4
