Answer:
Option C. 6 square units
Step-by-step explanation:
we know that
Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.
Let
a,b,c be the lengths of the sides of a triangle.
The area is given by:

where
p is half the perimeter
p=
we have
Triangle ABC has vertices at A(-2,1), B(-2,-3), and C(1,-2)
the formula to calculate the distance between two points is equal to

step 1
Find the distance AB



step 2
Find the distance BC



step 3
Find the distance AC



step 4



Find the half perimeter p
p=
Find the area




Answer:
x < -11/6.
Step-by-step explanation:
−12x + 13 > 35
-12x > 35 - 13
-12x > 22
Divide both sides by -12 and invert the inequality sign:
x < -22/12
x < -11/6.
Answer:
The line equation in slope-intercept form is:

Hence, option D is true.
Step-by-step explanation:
Given the points
Finding the slope between the points




As the y-intercept is obtained by setting the value x = 0.
As we know that when x = 0, the vale of y-intercept y = 4
so the y-intercept is b = 4.
As the slope-intercept form is
substituting the slope m = -2/5 and the y-intercept b=4


Therefore, the line equation in slope-intercept form is:

Hence, option D is true.
