1) Jane is (x - y) years old
2) Anna was (x - 3) years old 3 years ago
3) Jane will be (x - y + 5) years old in 5 years
4) The sum of their current ages is (2x - y) years
Answer:
b. The graph of g(x) is a translation 10 units right and 8 units up from the graph of f(x).
Step-by-step explanation:
See attached image.
X2-6x+5 is the quadratic eqution
Answer:
In every 2.5 hours number of sales made by Lydia=10 sales
2.5 hours = 10 sales
Dividing both side by 2.5
In 1 hour = 4 sales
On a particular day
In 2 hours , number of sales made=6 sales
As we have to find number of sales in next 6 hours.
Total number of hours =2+6=8 hours
So, number of sales should be=8×4=32
But in 2 hours , she made 6 sales.
In order to meet his average sale , she should sell →32- 6=26 sales in next 6 hours.
y = - 
x - 2
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x + 5y = 10 into this form
subtract 2x from both sides
5y = - 2x + 10 ( divide all terms by 5 )
y = - x + 2 ← point- slope form with slope m = -
Parallel lines have equal slopes hence
y = - x + c is the partial equation of the parallel line
to find c, substitute ( 5, - 4 ) into the partial equation
- 4 = - 2 + c ⇒ c = - 4 + 2 = - 2
y = - x - 2 ← equation of parallel line
