Answer:
<h2>Sam cycled fast, at a rate of 10 miles per hour.</h2>
Step-by-step explanation:
To solve this problem we have to find the slope of each case. The definition of a slope is:
Where 
is the first point, and 
is the second point.
Let's find each slope.
<h3>Sam.</h3>
Let's use the points 
and 
Applying the definition of the slope, we have:
This relation means that Sam cycled 10 miles per hour.
<h3>Bobby.</h3>
Let's use the points 
and 
Bobby cycled 9 miles per hour.
Therefore, according to these ratios, Sam cycled fast, at a rate of 10 miles per hour.
Y=2x-3.
Answer B.
Proof
When y=1 then x=2
y=2x-3
1=2*2-3
1=4-3
1=1
.............
Answer:
x = 
Step-by-step explanation:
Given 2 intersecting chords, then the product of the parts of one chord is equal to the product of the parts of the other chord, that is
18x = 9 × 3 = 27 ( divide both sides by 18 )
x = 
=
44. You can come to this answer by using algebra,
1/2x = 22
Multiply both sides by 2(denominator) thus,
X = 44.
Or you can use lateral thinking and realise that if 22 is 50%, you need to multiply by 2 to reach 100%.
