We see that each triangle takes up precisely one half of the parallelogram. From this, we see that the area of a triangle is one half the area of a parallelogram, or the area of a parallelogram is two times the area of a triangle
TLDR: 1 is 3, 2 is 5, 3 is 8.
Luckily for you, question 1 and 2 are linear functions. You don’t have to do any extra calculations to find the rate of change, because it’s always consistent. Question 1 is 3, and question 2 is 5.
Question 3 involves the evaluation of a quadratic, so we have to do a little bit of math. Plug in the two endpoints of the interval into the equation to obtain their y-coordinate values; we’ll use these points to calculate the slope.
(1,3) and (3, 19)
Now, using the slope formula:
M=y2-y1 = 19-3 = 16=8
x2-x1 3-1 2
The slope for Question 3 is 8.
If the matrix is of 2 by 2 then we can find the determinant of the matrix.

Then (ad - bc ) gives you the determinant of the matrix.
For example,

= (2)(-2) - (1)(4)
= - 4 - 4
= -8
Answer:
see below
Step-by-step explanation:
The y-coordinate measures the vertical distance relative to the x-axis on the coordinate plane. A point that is 3 units below the x-axis will have a y-coordinate of -3. The y-coordinate is listed 2nd in an (x, y) ordered pair, so you're looking for an ordered pair with -3 in the second spot.
(Root symbol) and under that 3x. And then outside of the root symbol -2x
