Determine the slope
Since the equation is already given in slope-intercept form, we'd assume that the slope is the coefficient of x.
2 is the slope
To write the equation in perpendicular form, change the slope to opposite-reciprocal.
2 opposite-reciprocal is -1/2
So, the equation would be y= -1/2x - 3
Answer:
y= -1/2x - 3
A. 61.8 inches
B. 31.8 inches
C. 63.6 inches
D. 67.2 inches
Answer:
The answer is 63.6
Step-by-step explanation:
In order to determine the area of the quadrilateral, we have to know the values of its sides. The area of the quadrilateral is:
a= length of the quadrilateral
b=width of the quadrilateral
We know the area and the width of the quadrilateral, so we can determine its length:
Then, the perimeter of the quadrilateral is:
P=2*a+2*b
P=2*15+2*16.8
P=63.6
Finally, the perimeter is 63.6
C. 63.6 inches
That is because to find the length of the quadrilateral do this since you already know the width of the polygon:
252/16.8 = 15
Now that we know the length do this since this is the formula to find the perimeter or for me I would just 2x:
2(16.8) + 2(15) =
33.6 + 30 = 63.6
The perimeter of the quadrilateral is 63.6 inches

Answer:
x = 47
y = 94
Step-by-step explanation:
Givens
Let the larger number = y Note: y must be even. Why is that?
Let the smaller number = x
Equations
x = 1/2 y
x + y = 141
Solution
Substitute x from the first equation into the second equation
1/2 y + y = 141
Change 1/2 y to 0.5y
0.5y + y = 141
Combine the left
1.5y = 141
Divide both sides by 1.5
1.5y/1.5 = 141/1.5
Do the division
y = 94 And y is even.
================
x = 1/2y
x = 1/2*94
x = 47
Check
The smaller number is 1/2 the larger one This is correct.
47 + 94 = 141 and this also checks.
Answer:
x = 47
y = 94
Step-by-step explanation:
We know that one number is half another number and the sum of these two numbers is 141. We are to find the numbers.
Assuming and
to be the numbers, we can write it as:
--- (1)
--- (2)
Substituting the value of from (1) into (2) to get:
y = 94
Now substituting this value of in (1):
x = 47
Translating it in other words:
One number is double the other number and the sum of the two number is 141.
