Answer:
slope = - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 5 is in this form with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= - 
Answer:
<h2>Let the common ratio b x thus the part becomes</h2><h2>=5x and 4x respectively</h2>
<h2>Thus,ATQ</h2>
<h2>5x+4x= 54</h2>
<h2>9x=54</h2>
<h2>x= 6</h2>
<h2>Sam will get is £30 (putting the value of x)</h2><h2>and Bethan will get £24</h2>
Step-by-step explanation:
the circumference of a wheel is one revolution
so
formula: circumference=π*diameter
D=26cm (13*2 to find the whole length from one end to other)
so you'll do 3.14*26 equals 81.64
one revolution=81.64
30 revolutions=2,448.3 inches (times by 30 with 81.64)
