Answer:
12 weeks
Step-by-step explanation:
It will take Jackie 12 weeks to buy her car because she earns 172 per week.
If you divide 2000 buy 172 you end up with 11.6
if you multiply 11 and 172 you get 1,892 which is just a little under 2000
if you add another week = 172$ you will arrive at 2064 which is enough to buy
her car.
Hope this helps.
Answer:
y = -2x + 5
Step-by-step explanation:
Assuming this is linear, the slope would be constant. For every 1 x, y decreases by 2. This means that the slope is -2.
y = -2x + b
Now all we need is the y-intercept.
If we plug in the first point (1,3), we get:
3 = -2*1+b
3 = -2+b
b = 5
This is the y-intercept.
y = -2x + 5
Answer:
The system of inequalities is

The solution in the attached figure
Step-by-step explanation:
<u><em>The question is</em></u>
Write a system of linear inequalities.
Le
x ---> number of scarves knitted per week
y ---> number of knitted sweaters per week
we know that
Mary would like to spend no more than 40 hours per week knitting
The word "No more" means "less than or equal to"
so
----> inequality A
Mary would like to knit at least 5 items per week
The word "at least" means "greater than or equal to"
----> inequality B
Solve the system by graphing
The solution is the triangular shaded area
see the attached figure
Answer:
Step-by-step explanation:
Recursive formula
a1 = -17
a^n = a^n-1 + 5
Explicit formula:
a^n = -17 + (n-1) * 5
