sorry if I am wrong
4x - 3y =5
3y = 4x - 5
y = 4/3 x - 5/3
Equation of the line passing through the point (-6,3) and parallel to L
a) Parallel lines have same slope so slope = 4/3
y - 3 = 4/3(x + 6)
y - 3 = 4/3 x + 8
y = 4/3 x + 11
Answer:
Equation y = 4/3 x + 11
b) Perpendicular lines, slope is opposite and reciprocal so slope = -3/4
y - 3 = -3/4 (x + 6)
y - 3 = -3/4 x - 4.5
y = -3/4 x - 1.5
Answer:
Equation y = -3/4 x - 1.5
Answer:
2 tee shirts
5 sleeves
Step-by-step explanation:
Let the number of shortsleeves be S and longsleeves L.
Total is 7
That is
L + S = 7
Total money spent is $73, while shorts cost 9 and longs 11
Hence,
9S + 11L = 73
We now have two equations we can solve simultaneously. From the first equation,
L = 7 - S
Putting this in equation 2
9s + 11(7 - S) = 73
9s + 77 - 11S = 73
2S = 4
S = 2
Since s = 2, then L = 5
Answer:
Jo's age = x = 8 years
Step-by-step explanation:
Let
Jo's age = x
Jo's mother, Anne's age = 4x
In four years time, Anne will be three times as old as Jo.
Jo's age =3( x + 4)
Jo's mother, Anne's age = 4x + 4
How old is Jo?
Equate Jo's age and his mother's age
3(x + 4) = 4x + 4
3x + 12 = 4x + 4
3x - 4x = 4 - 12
-x = - 8
Divide both sides by -1
x = 8
Therefore,
Jo's age = x = 8 years
