Answer:
y= mx+c
-4= -3/5(-5) + c
-4= -3/5 *-5+ c
-4=3+c
-4-3=c
-7=c
therefore the equation of the line is y=-3/5x-7
Step-by-step explanation:
the equation of a line is
y=mx +c
where y is the y coordinate
where m is the slope
where x is the x coordinate
where c is the y- intercept
I may not help. But i believe it is something to do with the lowest common multiple between those 2 being 60
Answer:
(a) x + y = 63 OR 3x = 63
(b) 21
(c) 42
Step-by-step explanation:
Let Vijay's age be x and Ajay's be y.
Ajay is <u>twice</u> as old as Vijay
==> Ajay's age = 2 × Vijay's age
==> <u>y = 2x</u>
<h3>(a)</h3>
<u>Sum</u> of their ages = 63
==> x + y = 63
<em>Substituting</em><em> </em><em>2</em><em>x</em><em> </em><em>for</em><em> </em><em>y</em><em>:</em>
==> x + 2x = 63
==> 3x = 63
<h3>(b)</h3>
<em>Solving the above-obtained equation:</em>
<u>==> x = 21</u>
<h3>(c)</h3>
Ajay's age = 2 times that of Vijay
==> y = 2x
==> y = 2×21
<u>==> y = 42</u>
