Answer:
see explanation
Step-by-step explanation:
(i)
+ 
= 1 ( multiply through by 6 to clear the fractions )
2x + 3y = 6 ( subtract 2x from both sides )
3y = - 2x + 6 ( divide through by 3 )
y = - 
x + 2
(ii)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope ( gradient ) and c the y- intercept )
y = - x + 2 ← is in slope- intercept form ( that is part (i)
with gradient m = -
(-2/3)*(-2 1/4)*(3/4) Convert the mixed fraction to improper fraction.
(-2/3)*(-9/4)*(3/4) Then you multiply the numerators with numerators and denominators with denominators
(-2*-9*3) negative times negative is positive, so the negative sign is gone
-------------
(3*4*4*) The lines (-----) is the line of the fraction
54/48 This is the product of this multiplication, now you need to simplify
by reducing the numbers of the fraction
9/8 And that would be the answer
The volume of the cylinder with a height of 9 cm and a radius of 5 cm is 706.9 cm³, if the radius is doubled, the volume would be 2827.4 cm³ (4 times)
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Volume of cylinder = π * radius² * height = π * 5² * 9 = 706.9 cm³
If the radius is doubled:
Volume of cylinder = π * (2 * 5)² * 9 = 2827.4 cm³
The volume of the cylinder with a height of 9 cm and a radius of 5 cm is 706.9 cm³, if the radius is doubled, the volume would be 2827.4 cm³ (4 times)
