The diameter is 12 units long. Their equation could be seen in y = 1, because it is a horizontal line. From x = - 7 to x = 0 is 7 units. From x = 0 to x = 5, is 5 units. 5 + 7 = 12. This means the radius is 6. We will use this later. If you need another way to find the radius, let me know. I can just use distance formula.
We will use these endpoints to find the center.
Midpoint =

=

=

= (- 1, 1)
This is the center.
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.
Plug in our given information now.
(x + 1)² + (y - 1)² = 6²
(x + 1)² + (y - 1)² = 36 is your equation.
Find the unit rate, which is also known as slope, constant rate of change!
Skippy should invest $ 7500 in account offering 4 % interest and $ 2500 in account offering 8 % simple interest
<em><u>Solution:</u></em>
Given that Skippy has a total of $10,000 to split between two investments
One account offers 4% simple interest, and the other account offers 8% simple interest
Total interest earned = 500
Number of years = 1
Let the principal with rate of interest 4 % is x
So the principal for rate of interest 8 % is 10000 - x
Total interest earned = simple interest for 4 % interest + simple interest for 8 % interest
Simple interest is given as:

Where "p" is the principal and "r" is the rate of interest and "n" is the number of years
Therefore,


Therefore skippy should invest $ 7500 in account offering 4 % interest
And skippy should invest (10000 - x) = (10000 - 7500) = $ 2500 in account offering 8 % interest

Answer: 114
Step-by-step explanation:
Let the number be y
35% of y = 40
35/100 × y = 40
35y/40 = 100
Cross multiply
35y = 100×40
35y= 4000
y= 4000/35
y= 114.29
The number is 114.29
