So, Tim has $70, and Rebecca has $6 less than 1/10 of the total money that Tim has.
70 divided by 10 would be 7, then Rebecca has $6 less than the 1/10, which would conclude to Rebecca having $1.
Tim and Rebecca together have a total of $71!
Hope this helped!
Step-by-step explanation:
AuB={3,4,7,9}U{8,9,10,11}
The value of x is 1 .(C)
Step-by-step explanation:
Three or more points lying on a straight line are said to be collinear
In this question, B is the point between A and C. This means;
AB+BC=AC where;
AB=10x+1
BC=5x+1
AC=17
10x+1 + 5x+1 =17
15x+2=17
15x=17-2
15x=15
x=15/15 =1

We know that
the x-intercepts of the quadratic function f(x)=x²<span>−3x−10 is when
f(x)=0
</span>x²−3x−10=0
Group terms that contain the same variable, and move the
constant to the opposite side of the equation
(x²−3x)=10
Complete the square. Remember to balance the equation
by adding the same constants to each side.
(x²−3x+2.25)=10+2.25
Rewrite as perfect squares
(x-1.5)²=12.25----------> (+/-)[x-1.5]=3.5
(+)[x-1.5]=3.5----> x1=5
(-)[x-1.5]=3.5-----> x2=-2
<span>
the answer is</span>
the x-intercepts of the quadratic function are<span>
x=5x=-2</span>
