Two lawns more than last week so two more than something with n being that something is; n+2
-16t² + 180t
-16(2)² + 180(2)
-64 + 360

Answer:
it x=-2(y-7)
3
Step-by-step explanation:
Answer:
y = -2x - 7
Step-by-step explanation:
x - 2y = 6
-2y = -x + 6
Divide the whole equation by (-2)

slope = 1/2
Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/2)

(-3, - 1)
y -y1 = m(x -x1)
y - [-1] = -2(x - [-3])
y + 1 = -2(x + 3)
y + 1= x* (-2) + 3*(-2)
y + 1 = -2x - 6
y = -2x - 6 - 1
y = -2x - 7
Answer: 4x - 13
<h2>
Step-by-step explanation:
</h2>
<em>First, we need to get triple of x:</em>
Triple of x is: 3x
<em>Next is to get the difference between 3x and 13:</em>
x + 3x -13
4x - 13
Hence, the variable expression is 4x - 13
