the distance from the origin is 5, so
sqrt(x²+y²)=5
x²+y²=25
substitue y=x²
y+y²=25
y²+y-25=0
solve using calculator or the formula
to get
y =( -1+sqrt(1+4*25))/2
or y = (-1-sqrt(1+4*25))/2
the second solution is rejected because a square cannot be negative
the value of x is the positive or negative (sqrt... or -sqrt...) or y
Answer:
B.) Open circle on 3 and all numbers to the left shaded
Answer:
y = (-5/7) x + 1
Explanation:
The slope-intercept form of the line has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept
The given is:
5x + 7y = 7
To put this in slope-intercept form, we will need to isolate the y as follows:
5x + 7y = 7
7y = -5x + 7
y = (-5/7) x + (7/7)
y = (-5/7) x + 1
where:
m is the slope = -5/7
c is the y-intercept = 1

Answer:
$234 771.75
Step-by-step explanation:
Data:
Principal = $234 900
APR = 9 % = 0.09
Payment = $1890
Calculations:
1. Monthly interest rate
r = 0.09/12 = 0.0075
2. Interest for first month
Interest = 234 900 × 0.0075 = $1761.75
3. New Principal
Principal = $234 900.00
+ Interest = <u> + 1761.75
</u>
End of month = 236 661.75
- Payment = <u> - 1890.00
</u>
New principal = $234 771.75
The new principal is $234 771.75
