Answer: y=–2x–5
Step-by-step explanation:
The equation of a straight line:
y=mx+c
m must be the same for the two lines to be parallel.
y=mx+c
y=–2x+8 → m=–2
For a new equation:
x=–1, y=–3, m=–2, c=?
y=mx+c → –3=–2×(–1)+c
–3=2+c
c=–5
So:
y=–2x–5

Answer:
it represents a variable
Step-by-step explanation:
Andrew has saved 36 number of R5 coins, 90 number of R2 coins and 126 number of R1 coins.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The coins are in the ratio 2:5:7 respectively. If he has a R90 in R2 coins. If x represent the total coins, hence:
(5/14) * x = 90
x = 252
Number of R5 coins = (2/14) * 252 = 36
Number of R1 coins = (7/14) * 252 = 126
Andrew has saved 36 number of R5 coins, 90 number of R2 coins and 126 number of R1 coins,
