The data given are
<span>X -1 -2 -3 2 3
Y 3 5 7 -3 -5 

which fits into the linear equation
y = -2x + 1

Function 2
The rate of change or the slope of the line
(3 - 0) /(0 - (-1) = 3

The rate of change of function 1 is -2
The rate of change of function 2 is 3

The global surface water area is 361, 132,000 square metres. Calculate the volume of water needed to cause a 3mm in sea level.
vovangra [49]

Answer:

The volume of water is 396 cubic meter.

Step-by-step explanation:

Area of water, A = 132000 square meter

Height, h = 3 mm = 0.003 m

The volume of water is given by

V = Area x height

V = 132000 x 0.003

V = 396 cubic meter.

Factor each expression.<br><br> (9) 5a - 25<br><br> (10) 28 - 7x<br><br> (11) 12z + 28 - 7z - 3
Nimfa-mama [501]

Answer:

Step-by-step explanation:

Look for the GCF and then divide every term by the GCF to see what remains

(9) 5a - 25  ( GCF is 5 so take out 5 and divide every term by 5)

     5(a-5)

(10) 28 - 7x     ( GCF is 7 so take out 7 and divide every term by 7)

     7(4-x)

(11) 12z + 28 - 7z - 3=  (combine terms) =

       5x+25( GCF is 5 so take out 5 and divide every term by 5)

        5(x+5)

Due in 10 min help! <br> Find t.
lys-0071 [83]

Given:

A right angle triangle with angles 45, 45, 90 degrees.

Hypotenuse of the triangle = 7\sqrt{2} mm

Base of the triangle = t

To find:

The value of t.

Solution:

In a right angle triangle,

\cos \theta=\dfrac{Base}{Hypotenuse}

Using this trigonometric ratio in the given triangle, we get

\cos (45^\circ)=\dfrac{t}{7\sqrt{2}}

\dfrac{1}{\sqrt{2}}=\dfrac{t}{7\sqrt{2}}

\dfrac{7\sqrt{2}}{\sqrt{2}}=t

7=t

Therefore, the value of t is 7 millimetres.

The area of a rectangular garden can be expressed as A = 2x^2 -x -6. The width of the garden is 2x+3. Find an expression for the
zalisa [80]

Answer:

Step-by-step explanation:

2x² -x - 6 = 2x² - 4x + 3x - 3*2

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

              = (x-2)(2x + 3)

A = 2x² -x - 6

A = (x - 2)(2x + 3)

length*width = (x - 2)(2x + 3)

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

length=\frac{(x-2)(2x+3)}{(2x+3)}

length = x - 2
