Answer:
y <
Step-by-step explanation:
We will find the equation of the dotted line first.
Let the equation of the line is,
y = mx + b
Here, m = slope and b = y-intercept of the line
Slope 'm' =
m =
m =
Y-intercept 'b' = -3
Therefore, equation of the line is,
y =
Since, this line is a dotted line, it will represent an inequality with notation of less than or greater than (< or >)
Since, solution area (shaded area) of this inequality is below the line inequality will be,
y <
Answer:
6 inches squared
Step-by-step explanation:
The triangle is a right triangle. We can see this because it is attached a rectangle, which has angles of 90 degrees.
Now, notice that the hypotenuse is given as 5 inches and one of the legs is given as 3 inches. We can use the Pythagorean Theorem to find the third side: x =
The area of a triangle is A = (1/2) * b * h, where b is the base and h is the height perpendicular to the base. We know the base is 3, so b = 3, and we also see that the height is 4, so h = 4. Plugging these in:
A = (1/2) * b * h = (1/2) * 3 * 4 = 6
Thus, the area of one of the triangular faces is 6 inches squared.
Hope this helps!
