Semenov [28]3 years ago
4 0

Answer:

D

Step-by-step explanation:

y=2x²+2x+1.... i

y=2x+3......... ii

Equating i and ii,

2x²+2x+1=2x+3

2x²+1-3=0

2x²-2=0

x²-1=0

x=1 or -1.

From ii, if x=1,y=5

If x=-1, y=1.

The points are (-1,1) and (1,5)

Find the length and width of a rectangle.<br> Perimeter = 50<br> Side A = 3x + 2<br> Side B = x - 5
zmey [24]

Step-by-step explanation:

Perimeter = 2 * (Side A + Side B)

= 2 * (3x + 2 + x - 5)

= 2 * (4x - 3)

= 8x - 6.

We have 8x - 6 = 50, so 8x = 56 and x = 7.

Length of rectangle = 3(7) + 2 = 23.

Width of rectangle = (7) - 5 = 2.

What equation can I use to find the side of a cube whose area is 729?
Tom [10]
#1 There is no area of a cube. There is only a volume.
#2 The formula is V = s^{3} where s is the side.

Substitute 729 in V since that is the volume.
729 = s^{3}

Take the cube root and you will get 9.

So the formula is V = s^{3} and the side is 9.

Graph the data below and then answer the questions that follow. year 1=$20,000, year 2=$21,750, year 3=$23,500, year 4=$25,250,
Mariana [72]

Answer:

Since the difference between the value for each year is constant, this is an arithmetic sequence.

Step-by-step explanation:

Year 2 - Year 1 = 21,750 - 20,000 = 1,750

Year 3 - Year 2 = 23,500 - 21,750 = 1,750

Year 4 - Year 3 = Year 5 - Year 4 = 1,750
