Answer:
x = 1, y = 4, or x = -2, y = 1
Step-by-step explanation:
y = -x^2 + 5
-x + y = 3
Use substitution to solve for the equation
-x + (-x^2 + 5) = 3
-x^2 - x + 5 = 3 (simplifying)
-x^2 -x + 2 = 0 (simplifying)
(-x + 1)(x+2) = 0 (factoring)
-x + 1 = 0 or x + 2 = 0
x = 1, or x = -2
-x + y = 3
-(1) + y = 3, or -(-2) + y = 3
y = 4, or y = 1
just choose any one...
x = 1, y = 4
or x = -2, y = 1
(they both work)

Use the add-on method for determining interest on a loan of $,2540 with an annual rate of 6% and a term of 4 years. Then, determine the annual interest rate during the last month of the loan.
Answers
Answer:
Part A
The interest on the loan is $609.6
Part B
The interest amount on the last month is $12.7
Step-by-step explanation:
Part A
With the add-on interest method, the interest on the loan is added before the monthly payment is determined
The monthly payment, A = (P × I)/n
Where;
A = The amount payed monthly
P = The principal amount borrowed = $2,540
I = The interest on the loan = P × R × T
R = The interest on the loan = 6%
T = The duration of the loan = 4 years
n = The number of monthly payment = 4 × 12 = 48
Plugging in the variables to the simple interest formula, we get;
I = $2,540 × 6/100 × 4 = $609.6
The interest on the loan, I = $609.6
Part B
The monthly payment is therefore;
∴ A = ($2,540 + $609.6)/48 = $65.61[tex]\overline 6[/tex]
The amount payed as interest on the last month, [tex]I_m[/tex], is given as follows;
$65.61[tex]\overline 6[/tex] - $2,540/48 = $12.7
The amount payed as interest on the last month = $12.7

Answers
Answer:
Step-by-step explanation: both graphed is D
The graph D represents the solution of the system of the equation.
What is the system of equation?One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given, the system of equation;
y = -3x - 5 {equation 1}
y = 3x + 1 {equation 2}
Add both of the equation:
2y = -4
y = -2
And x = 1
And the solution set is (1 , -2).
And only D have the solution set (1 , -2)
Therefore, the graph D represents the solution of the system of the equation.

Answer:
C
Step-by-step explanation:
First, eliminate choice B b/c the max is 28, not 26.
Next, lets find the median.
(12+18+20+20+24+26+28+28) = (20+24)/2 = 22
That leaves us with only A & C as a possible answer.
Q1 = The median of the first half of the data (12, 18, 20, 20)
Q1 = (18+20) / 2 = 19
A & C have the same Q1 values, so we need to compare Q3 values.
Q3 = The median of the second half of the data (24, 26, 28, 28)
Q3 = (26+28) / 2 = 27
The Correct Answer is C b/c A had a different Q3 value.

The actual length of a building is 168 feet and its width is 152 feet. If the scale length of the bulding in the drawing is 21 inches and the width is 19 inches what scale was used in the drawing
Answers
Answer:
40
Step-by-step explanation:
Answer:
1 inch = 8 feets
Step-by-step explanation:
Actual Length = 168 feets
Scale length = 21 inches
168 / 21 = 8
Actual width = 152 feets
Scale width = 19 inches
152 / 19 = 8
Hence, we can conclude that
Scale used :
1 inch = 8 feets
That is 1 inch in drawing equals 8 feets of the actual size
