What is the equation of a line that goes through the point (3, 12) and is perpendicular to the line given by the equation y = -1

/3x - 7?
y = -3x - 12
y = -1/3x + 6
y = 3x + 3
y = (1/3x) - 6

Y=3x+3

Perpendicular lines have the product of their gradients =-1
since gradient of line 1 =-1/3
then gradient of line 2 is
-1/3*m=-1
m=3

Roxanne has 1/2 as many beads as Sherie. The number of beads Sherie has is 4/5 that of ting ting's. Ting Ting has 165 beads. How

Rom4ik [11]

Step-by-step explanation:

T = beads of Ting Ting = 165

S = beads of Sherie.

R = beads of Roxanne.

S = 4/5 × T = 4/5 × 165 = 4 × 33 = 132 beads

R = 1/2 × S = 1/2 × 132 = 66 beads

Ting Ting has therefore 165 - 66 = 99 more beads than Roxanne.

How to solve this math -9(-6w+3u-4)

Goryan [66]

-54w-27u+36 because -9 times 6 = 54 and -9 times 3 = 27 and -9 times -4 = 36 so -54w -27 u + 36

A hovercraft takes off from a platform. Its height (in meters), xx seconds after takeoff, is modeled by: h(x)=-2x^2+20x+48h(x)=?

tangare [24]

Answer: 5 seconds

<u>Step-by-step explanation:</u>

Maximum height is the y-value of the vertex. The number of seconds at maximum height is the x-value (aka axis of symmetry).

h(x) = -2x² + 20x + 48

a=-2 b=20 c=48

Axis of symmetry: x = $\frac{-b}{2a}$

= $\frac{-20}{2(-2)}$

= $\frac{-20}{-4}$

= 5
