Answer:
20
Step-by-step explanation:
Let Kayla's age be k.
Let Isaac's age be a.
Kayla is 6 years older than Raoul. This means that:
k = y + 6
lsaac is 4 years younger than Raoul. This means that:
a = y - 4
y = 12
=> k = 12 + 6 = 18
and
a = 12 - 4 = 8
The sun of Raoul's age and Isaac's age is:
12 + 8 = 20
Answer:
see explanation
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ), thus
P(1, - 1 ) → P'(1, 1 )
Q(3, - 2 ) → Q'(2, 3 )
R(3, - 4 ) → R'(4, 3 )

(b) 2 phones calls
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer: f(x) = (2/3)*x -3 -- which is not a provided answer..
Discussion:
We are given that y + 7 = (2/3) * (x + 6). Multiply out the right hand side:
y + 7 = (2/3) * x + (2/3) * 6 = (2/3) *x + 12/3
= (2/3)*x + 4
Subtract 7 from both sides:
y + 7 - 7 = (2/3)*x + 4 - 7
or
y = (2/3)*x -3
Thank you,
MrB
y + 7= 2/3(x+6)
Hope this helps
