If you are trying to find the area of each side you created when dividing the triangle into thirds, you should divide your numbers. Since the area of the whole triangle is 18 sq. units, and you need three separate pieces from the triangle, you can divide 18 by three. This would look like this:
18 / 3 = ?
And 18 / 3 = 6. So from that you can tell that each third of the triangle is going to equal 6 sq. units.
Hope that helps!
This would only be a double bracket...
but you do
(4x+6) (x-3)
F 4x * X = 4xsquared
O 4x* -3 = -12x
I. 6xX = 6x
L. 6*-3 = -18
collect like terms:
answer= 4x2 - 6x -18
the 4x is squared :)
The equation of the perpendicular line is y + 7 = -1/7(x - 3)
<h3>How to determine the line equation?</h3>
The equation is given as
y = 7x + 14
Also, from the question
The point is given as
Point = (3, -7)
The equation of a line can be represented as
y = mx + c
Where
Slope = m
By comparing the equations, we have the following
m = 7
This means that the slope of y = 7x + 14 is 7
So, we have
m = 7
The slopes of perpendicular lines are opposite reciprocals
This means that the slope of the other line is -1/7
The equation of the perpendicular lines is then calculated as
y = m(x - x₁) +y₁
Where
m = -1/7
(x₁, y₁) = (3, -7)
So, we have
y = -1/7(x - 3) - 7
Evaluate
y = -1/7(x - 3) - 7
Add 7 to both sides
y + 7 = -1/7(x - 3)
Hence, the perpendicular line has an equation of y + 7 = -1/7(x - 3)

Answer:
Step-by-step explanation:
Answer:
is the answer.
Step-by-step explanation:
Let the equation of the exponential function is,
Two points from the given table which lie on the graph are (0, 0.2) and (1, 0.1)
For a point (0, 0.2),
0.2 =
a = 0.2
For another point (1, 0.1),
0.1 =
b = = 0.5
Therefore, exponential function defined by the given table is,
