Answer:
2667
Step-by-step explanation:
4+4x6+3+9{9+89}x3 = 2667
Answer:
(1,2021)
Step-by-step explanation:
P and q can vary subject to their sum being 2020.
Consider one parabola with p1 and q1 and another with p2 and q2.
y1=(x1)^2+(p1)(x1)+(q1)
y1=(x2)^2+(p2)(x2)+(q2)
At their intersection, the x and y coordinates are the same.
y1=y2=y
x1=x2=x
x^2+(p1)x+(q1)=x^2+(p2)x+(q2)
Solve for x
x(p1-p2)=q2-q1
x=(q2-q1)/(p1-p2)
Use the constraint that p+q=2020 to eliminate p1 and p2.
p1=2020-q1
p2=2020-q2
x=(q2-q1)/(2020-q1-2020+q2)
x=(q2-q1)/(q2-q1)
x=1
Substitute in the equation for y.
y=1^2+p(1)+q
y=2021
Answer:
x=21
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
Answer:
48 = 12 +9w
36 = 9w
w = 4
Worked out:
you need 48 dollars, you already have 12. so now you need to save 9 per week, which would be 9w. so you would want to add 9w to 12 to get to 48. simplifying and solving for <em>w</em> would be 4 weeks
