Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
The formula of a slope:
Q1.
We have the equation of a line <em>p </em>in the standard form
Convert to the slope-intercept form:
<em>subtract 3x from both sides</em>
<em>divide both sides by (-3)</em>
The slope
From the table we have the points (4, 3) and (7, 5). Calculate the slope of line <em>q</em>:
Divide the slope of <em>p</em> by the slope of <em>q</em>:
Q2.
Parallel line have the same slope. Therefore, if we have the equation of the line in the slope-intercept form, then we have the slope:
Q3.
Parallel line have the same slope.
Calculate the slope from given points (-11, 5) and (-6, 1):
The length is two times its width, and the perimeter equals 24.
All the sides added up equal 24.
4 and 8 could be the width and the length of the rectangle.
4*2= 8 and
4+4+8+8= 24
width= 4 length= 8

Answer:
x = 0 and y = 3
Step-by-step explanation:
Using elimination method, we can solve for x and y in the simultaneous equation
y = 2x + 3 .................................eqn 1
y = -3x + 3 .................................eqn 2
multiply equation 1 by 3 and equation 2 by 2, then we will have
(y = 2x + 3) × 3
(y = -3x + 3) × 2
3y = 6x + 9 ...............................eqn 3
2y = -6x + 6 ................................eqn 4
Add eqn 3 and 4 together and we will eliminate x and have
5y = 15
Divide both sides by 5, and we will have
y = 3
To solve for x, substitute 3 for y in eqn 1
y = 2x + 3
3 = 2x + 3
collect like terms
3 - 3 = 2x
0 = 2x
Therefore x = 0
Let's factorise and use the difference of two squares (D.O.T.S):
the (x-2) in the numerator and denominator cancel out so we are left with:
So the answer is B
