Answer:
Step-by-step explanation:
(x – 4)(x – 4) = 0.
So factor are x-4=0
X=4 (D) is the answer
x = 3
x + y + y + 17 + y = ?
Thanks!!
Answer:
y = - x + 9
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given the line with equation
2x + 2y = 18 ( subtract 2x from both sides )
2y = - 2x + 18 ( divide through by 2 )
y = x + , that is
y = - x + 9 ← in slope- intercept form
Answer:
x=3.5
Step-by-step explanation:
To solve for x , we need to make same base on both sides
9 can be written as 3^2
27 can be written as 3^3
[tex[](3^2)^{x - 2} = 3^3[/tex]
multiply the inside exponent with inside exponent
Both sides have same base 3
so we equation the exponents
add 4 on both sides
divide by 2 on both sides
2, 3i, -3i are the real and complex solutions of the polynomial equation.
Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables
The given polynomial is x³-2x²+9x-18
x³-2x²+9x-18=0
Take the common terms from first two terms
x²(x-2)+9(x-2)
(x²+9)(x-2)=0
(x²+3²)(x-2)=0
x-2=0
x=2
and x²+3²=0
x=3i and x=-3i
Hence, 2, 3i, -3i are the real and complex solutions of the polynomial equation.

Answer:
$1 coin is 23
$2 coin is 14
Step-by-step explanation:
We need to form mathematical equations that we can solve from this Long citation.
Firstly, let the numbers of $1 coins be a and that of $2 be b.
We know that there are 37 coins. Hence
a + b = 37
Now, total is 51 Canadian dollars.
a + 2b = 51
Let’s now solve this simultaneously
From 2 , a + b + b = 51
Let’s say this is 3. Now substitute 1 into 3.
37 + b = 51, b = 51 - 37 = 14
Since a + b = 37
a = 37 - 14 = 23
