Let
x------> Cathy's<span> ages
</span>y------> Tony's ages
we know that
x+y=65-----> x=65-y-----> equation 1
y-8=(2/5)*(x-8)-----> equation 2
substitute equation 1 in equation 2
y-8=(2/5)*(65-y-8)---> y-8=22.8-0.4y----> y+0.4y=22.8+8
1.4y=30.8-----> y=22
x=65-y-----> x=65-22----> x=43
the answer is
Cathy's ages is 43 years
Tony's ages is 22 years
Answer:
Please provide more information so the question could be answered
Step-by-step explanation:
KJ^2=6^2+3^2
KJ=the square root of 36+9
KJ=square root of 45
kJ= 3 times the square root of 5
The answer is D
Start at 4 and since it a negative go down one and over one
Step-by-step explanation:
4 is the A or Ampltiude
To find the period set it equal to 2 pi/B
b=
b=
There is no phase shift
The midline or d or vertical shift is 1.
Our equation for 8 is
9.Use sin function. The a value is 2 or -2 your choice.
Set up the period equal to the equation
Which equal 6.
B=6
There is no C and the D and Vertical Shift is 1.
Our equation is
