I don't know if you still need help with this, but the answer is exact interest and he saves $1.34.
The answer is g. U need to find the domain to be able to solve all your other steps.
Answer:
x = -1 and y = -3
Step-by-step explanation:
The given equations are :
2x+3y= -11 ...(1)
8x -2y= -2 ...(2)
We need to solve the equations.
Multiply equation (1) by 4.
8x+12y= -44 ...(3)
Subtract equation (2) from (3).
8x+12y-(8x -2y) = -44-(-2)
8x+12y-8x +2y = -42
14y = -42
y = -3
Put the value of y in equation (2).
8x -2(-3)= -2
8x+6 = -2
8x = -8
x = -1
So, the values of x and y are -1 and -3 respectively.
Answer:
The answers should be
x^2 + 8x + 7
x(x + 8) +7
Step-by-step explanation:
(x + 7)(x + 1)
x(x) + x(1) + 7(x) + 7(1)
x^2 + x + 7x + 7
x^2 + 8x + 7
f(x) = 3x^2+12x+5f(x)=3x 2 +12x+5f, left parenthesis, x, right parenthesis, equals, 3, x, squared, plus, 12, x, plus, 5 What is

Answer:
Discriminant = 84
The polynomial has two real distinct roots
Step-by-step explanation:
Given: 
To find: discriminant of the given function and number of distinct real zeros
Solution:
For a polynomial 
, discriminant is given by 
If 
, then the polynomial has two real and distinct roots.
If 
then the polynomial has two real and equal roots.
If D<0 then roots are not real.
Here, in
a = 3, b = 12 and c = 5
As D > 0, the polynomial has two real distinct roots.
