How many solutions will this system of equations have? y = 3.5x − 3.5 y = −3.5x + 3.5

1 answer:

3 0

We have that
<span>y = 3.5x − 3.5
y =−3.5x + 3.5

using a graph tool
see the attached figure

the solution is the point (1,0)
x=1
y=0

the answer is
one solution</span>

There's a simple formula for the area of an ellipse: pi*a*b, where a and b are , half the lengths of the long axis and the short axis respectively.

Here, A = pi*(12 ft)(4 ft) = 48 pi ft^2, or about 150.8 ft^2.

Find the coordinate A if M (-5,-9) is the midpoint of AB and B has coordinate of (3,-5)

rodikova [14]

The coordinates of Point A are (-13,-13)

Step-by-step explanation:

The formula for mid-point of two points (x1,y1) and (x2y2) is given by:

$M = (\frac{x_1+x_2}{2} , \frac{y_1,y_2}{2})$

Given

M = (-5,-9)

B(x2,y2) = (3,-5)

Putting the values

$(-5,-9) = (\frac{x_1+3}{2} , \frac{y_1-5}{2})$

Comparing respective elements

$\frac{x_1+3}{2} = -5\\x_1+3 = -5 * 2\\x_1+ 3 = -10\\x_1 = -10-3\\x_1 = -13\\AND\\\frac{y_1-5}{2} = -9\\y_1-5 = -9 * 2\\y_1-5 = -18\\y_1 = -18+5\\y_1 = -13$

Hence,

The coordinates of Point A are (-13,-13)

Lea made two candles in the shape of right rectangular prisms. The first candle is 15 cm high, 8 cm long, and 8 cm wide. The sec

algol [13]

15*8*8 = 960 (volume of original candle)
20*8*8 = 1280 (volume of taller candle)
so that's an extra 320 cubic cm of wax
