Answer:
a+b=6
a-b =4
______subtract
(a-a)+(b-(-b))=6-4
0+2b = 2
b= 1
put the value of b at any equation
a+1 =6
then a=6-1=5
a square+b square= 25+1= 26
Say x is the number of weeks until their money is equal. Then, we can set up an equation.
400 + 25x = 250 + 75x
Subtract 250 from both sides
150 + 25x = 75x
Subtract 25x from both sides
150 = 50x
Divide by 50 on both sides
3 = x
That means the answer is 3 weeks.

the number in the tenth place is 7 and It can´t be changed because 1 isn´t 5 or it also isn´t greater than 5.
Answer:
Maximum value:
the maximum value is 
Minimum value:
the minimum value is 7
Step-by-step explanation:
We are given function as
Firstly, we will draw graph
we can see the graph
and then we can identify maximum and minimum
Maximum value:
We know that
the largest y-value means maximum value of f(x)
We can see that curve is moving upward
so, the maximum value is
Minimum value:
We know that
the smallest y-value means minimum value of f(x)
we can see that
It starts from point (5,7)
so, the minimum value is 7
Thee function is given as:
<span>v(t)=t^2−2tv(t)=t^2−2t
</span>(a) What is the initial velocity?
Base from the function, the initial velocity would be zero.
(b) When does the object have a velocity of zero?
It would be during time zero. Also, at a time equal to two.
