Answer:
x = 6 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the height )
Here b = 12 and h = 4, then
A = × 12 × 4 = 6 × 4 = 24 cm²
Then area of parallelogram = 3 × 24 = 72 cm²
The area (A) of a parallelogram is calculated as
A = bh ( b is the width and h the height )
Here b = x and h = 12, thus
12x = 72 ( divide both sides by 12 )
x = 6
The width of the parallelogram is 6 cm
Answer:
{(-14,9),(4,-7),(-8,6)}.
Step-by-step explanation:
To find the inverse you just swap x and y.
So if (a,b) is a point on the relation then (b,a) is on it's inverse.
So the inverse of {(9, –14), (–7, 4), (6, –8)} is:
{(-14,9),(4,-7),(-8,6)}.
A equals to 2.
<u>Step-by-step explanation:</u>
y = mx + c is the equation of the line and m is the slope and c is the y- intercept.
In the given equation, y = ax , a is the slope.
Slope A can be found by means of the formula, and using the points (2,4) and (-2-4)
slope, A = (y₂ -y₁) / (x₂-x₁)
Plugin the values as,
A = (-4-4) / (-2-2) = (-8) / (-4) = 2
So the value of A is 2.
You got add all the numbers up and divide it by how many numbers there are to get the average.
9.4 +9.7 + 9.9 + 9.8 = 38.8 divided by 4 =9.7 is Joey's average.
9.5 +9.2 +9.7 +9.6 =38 divided by 4 = 9.5 is Carlos' average.
Joey has more average by 0.2.
