Answer:
D
Step-by-step explanation:
Given the 2 equations
4x - 5y = 18 → (1)
3x - 2y = 10 → (2)
Multiplying (1) by 3 and (2) by - 4, then adding will eliminate the x- term
12x - 15y = 54 → (3)
- 12x + 8y = - 40 → (4)
Add (3) and (4) term by term to eliminate x, that is
- 7y = 14 ( divide both sides by - 7 )
y = - 2
Substitute y = - 2 into either of the 2 equations and solve for x
Substituting into (1)
4x - 5(- 2) = 18
4x + 10 = 18 ( subtract 10 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
solution is (2, - 2 ) → D
The height of the oblique triangular pyramid is 18 units if the base area of 21 square units and a volume of 126 cubic units.
<h3>What is volume?</h3>
It is defined as a three-dimensional space enclosed by an object or thing.
We know the volume of an oblique triangular pyramid is given by:

Where b is the area of the base and h is the height of the pyramid.
We have b = 21 square units and V = 126 cubic units.

h = 18 units
Thus, the height of the oblique triangular pyramid is 18 units if the base area of 21 square units and a volume of 126 cubic units.

Answer:
The equation that represents the line passing through the point (2, -4) with a slope of one half is

Step-by-step explanation:
The equation of a line can be described by a first order equation in the following format:

In which a is the slope of the line.
Solution:
The line slope is
, so
.
The equation of the line now is:

The problem states that the line passes through the point(2,-4). This means that when x = 2, f(x) = -4
So:




So, the equation that represents the line passing through the point (2, -4) with a slope of one half is
