X + 3y = 7
x = -3y + 7
2x + 4y = 8
2(-3y + 7) + 4y = 8
-6y + 14 + 4y = 8
-2y = 8 - 14
-2y = - 6
y = -6/-2
y = 3
x + 3y = 7
x + 3(3) = 7
x + 9 = 7
x = 7 - 9
x = -2
solution is (-2,3)
It will just be x=1 and y=7
Answer: the area of the rectangle is 4000 meter square.
Step-by-step explanation:
Answer:
r = 35 / ( 3200 × 12 ) = 0.00091146
r = 0.00091146
converting r decimal to a percentage
R = 0.00091146 * 100 = 0.0911%/year
The interest rate required solve for the simple interest of $ 35.00
from a principal of $ 3,200.00
over 12 years is 0.0911% per year.
Step-by-step explanation:
Answer:
The zeros of the given function are -9,-1 and 12.
Step-by-step explanation:
The given function is

It is given that the x-intercept of the graph is -9, therefore -9 is a zero of the function.
Since -9 is the zero of the function, therefore (x+9) is a factor of f(x). Use synthetics method or long division method to divide the function by (x+9).




Use zero product property and quote each factor equal to 0.

Therefore zeros of the given function are -9,-1 and 12.
