Answer:
A (-1,-6)
Step-by-step explanation:
A system of equations is a set of two or more equations which intersect at a point (x,y). This is the solution. Any system can be solved using graphing, elimination or substitution. To solve this system of equations, use elimination. Line up each variable and subtract the like terms.
2x - 3y = 16
5x - 3y = 13
---------------------
-3x = 3
x = -1
Substitute x = -1
2(-1) - 3y = 16
-2 - 3y = 16
-3y = 18
y = -6
Answer:
<h2>
(1000m⁹)²</h2>
Step-by-step explanation:
A monomial is an expression containing just one term. Given the monomial 1000000m¹⁸, to get the monomial we need to raise to the power of 2 to get this given monomials, the following steps must be taken using the laws of indices.
In indices,
, applying this rule to the question we have;
1000000m¹⁸
= (10*10*10*10*10*10)m¹⁸
= 10⁶m¹⁸
= 10⁶*(m³)⁶
= (10*m³)⁶
= (10m³)⁶
= (10m³)²ˣ³
= (10³m⁹)²
= (1000m⁹)²
The last result gives the required expression
Answer:
x = 2
Step-by-step explanation:
To find the value of x, we simply need to use the know values for the lengths, widths, and perimeter of the rectangle.
The formula for the perimeter of a rectangle is as follows:
P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
Let L = 7x + 5 and W = x - 3
Now, we will simply plug our values into the formula and solve for x.
P = 2L + 2W
36 = 2 ( 7x + 5 ) + 2 ( x - 3 )
36 = 14x + 10 + 2x + -6
36 = 16x + 4
32 = 16x
2 = x
Thus, we have found the value of x to be 2.
Cheers.
I believe it's C E.
They both look pretty equal and line up perfectly with E. Hope this helps!
