Answer: y≤4x+3 and y≤-3x-5

Step-by-step explanation:

The slope of the first line is 4. The slope of (-1,-1) and (0,3) is 4. And the line passes through 3, so the y-intercept is 3.

The slope of the second line is 3. The slope of (-3,4) and (-1,-2) is -3. And the line passes through -5, so the y-intercept of the second line is -5

A 85 inch piece of pipe is cut into three pieces, so that the second

nikdorinn [45]

Answer:

Step-by-step explanation:

x 2x 3x + 1

|---------|-------------------|---------------------------|

|<-------------------- 85 in ------------------------>|

85 = x + 2x + 3x + 1

85 - 1 = 6x

x = 84 / 6

x = 14

1st piece = 14 in

2nd piece = 2(14) = 28 in

3rd piece = 3(14) + 1 = 43 in

----------------------------

total = 85 in

A rectangular field has the area equal to that of a square field of side 60m.if the breadth of the rectangular field is 32m, fin

V125BC [204]

<u>Given</u> -

Area of rectangular field = Area of square field
side of square = 60m
breadth of the rectangular field = 32m

<u>To find</u> -

length of the rectangular field

<u>Solution</u> -

Area of square = side × side = (60 × 60)m² =

Area of square =3600m²

Hence,

Area of rectangular field = Area of square field = 3600m²

Area of rectangular field = l × b = 3600m²

=> l × 32m = 3600m²

=> l = $\sf{\frac{3600}{32}\:m}$

=> l = 112.5m

so, the length = 112.5m

Please solve this for me please

Natalka [10]

I’m having trouble reading your equations is it
(2i-1/x+1)^(4)-13(x-1/x+1)^(2)+36=0
I just want to confirm before doing it just comment if that’s the correct equation.
