The first one x(y-5)=2 if you go
On desmos and put that equation in you will see
Answer:
Area of a circle = 3.14 X radius X radius
= 3.14 X 4.5 X 4.5 = 63.585 m2
Hope this helps....
We are given equation: y=ln(x) .
And translation is 5 units down.
We know the rule of transformation f(x) = y + k, if k is greater than 0 it would move up or if k is less than 0, it would move down.
For the given translation 5 unit down, 5 should be less than 0.
Number less than 0 are negative numbers.
So, we need to add -5 in the given function to ln(x).
So, we would get the final equation for five units down as
y =ln(x) - 5.
Answer: she worked 8 hours at Job A
She worked 16 hours at Job B
Step-by-step explanation:
Let x represent the number of hours that she worked job A.
Let y represent the number of hours that she worked job B.
Kathy works two part-time jobs for a total of 24 hours a week. This means that
x + y = 24
Job A pays $6.00 per hour, and Job B pays $7.30 per hour and she made $164.80 for the week. it means that
6x + 7.3y = 164.80 - - - - - - -1
Substituting x = 24 - y into equation 1, it becomes
6(24 - y) + 7.3y = 164.80
144 - 6y + 7.3y = 164.80
- 6y + 7.3y = 164.80 - 144
1.3y = 20.8
y = 20.8/1.3 = 16
x = 24 - y = 24 -16
x = 8
Solve the second equation for y
Substitute the given value of y into the first equation
Solve the equation for x
Substitute the given value of x into the second equation
Solve the equation for y
The possible solution of the system is the ordered pair (x,y)
