Answer:

Perimeters = 3 in : 7 in

Areas = 9 in² : 49 in²

Step-by-step explanation:

If the figures are squares, and the measurements are the length of that sides (as you have said), then we will do the following.

[The left square]

P = 4a

P = 4(15)

P = 60 in

A = a²

A = 15²

A = 225 in²

[The right square]

P = 4a

P = 4(35)

P = 140 in

A = a²

A = (35)²

A = 1,225 in²

[Simplifying ratios]

Perimeters = 60 in : 140 in

Perimeters = 6 in : 14 in

Perimeters = 3 in : 7 in

Areas = 225 in² : 1,225 in²

Areas = 45 in² : 245 in²

Areas = 9 in² : 49 in²

Which equation represents a line that passes through (–9, –3) and has a slope of –6?

tatiyna

Answer:

y+3 = -6(x+9)

Step-by-step explanation:

m(x-x1)= (y-y1)

-6[x-(-9)] = [y-(-3)]

-6(x+9) = y+3

What is the y-intercept of the line represented by the equation y = 2x - 3?

cestrela7 [59]

Y =Mx + C
where M = gradient / slope
C = y intercept

comparing with y = 2x - 3
M = 2
C = -3
