Find an equation of the line with the given properties parallel to y=-1/3x-2 containing the pt (6,-10)
Salsk061 [2.6K]

Answer:

y + 10 = -1/3 (x - 6) OR y = -1/3x-8

Step-by-step explanation:

take the slope of y = -1/3x - 2 (the slope is -1/3)

plug the slope and the point into this equation: y - y1 = m (x - x1)

m represents your slope, y1 and x1 represnt your points so just plug in

so y + 10 = -1/3 (x - 6) or y = -1/3x-8 (subtract 10 from both sides and distribute the -1/3 to (x -6)).

Maria is 11 inches shorter than her sister Nancy.Brad is 11 inches than his brother Chad.If Maria is shorter than Brad,how do th
nexus9112 [7]

Answer:

Let M represents Maria's height, N represents Nancy's height, B represents Brad's height and C represents Chad's height.

Note : all heights are in inches.

Given,

M < N

Such that M = N - 11,

B < C,

Such that, B = C - 11,

M < B,

⇒ M < B < C,

Thus, there is the less information to compare the height of Nancy and Chad.

If M = B,

Then M = C - 11 ⇒ C = M + 11

But N = M + 11

⇒ C = N

Thus, if Maria and Brad are the same height then the height of Nancy and Chad will same.

How to solve for x in these shapes?
DiKsa [7]

Answer:

Step-by-step explanation:

a

sum of angles of a quadrilateral=360°

4x+5x+20+5x-10+3x+10=360

17x=360-20

17x=340

x=340/17

x=20

b.

sum of angles= (n-2)×180

where n is the number of sides.

5x+4x+2+5x+6+2x-2+3x+5+x-10=(6-2)×180

20x+1=720

20x=719

x=35.95

I NEED SOME HELP AGAIN PLS
ozzi

Answer:

The y-intercept is (26, 0)

Step-by-step explanation:

The Y intercept is the point at which the line crosses the  y-axis, or when x is equal to zero. Here when x = 0, y = 26. So the y-intercept is (26, 0). They want to trick you into choosing the slope is -1/6, but that is wrong because id you look at the x-axis it is not going by 1's.
