Answer:
The ordered pair of P'=(-8.75, 5.25)
Step-by-step explanation:
To get the ordered pair of point P' you simply have to multiply the coordinates of P by scale factor of 7/4
P:(-5,3)
P'(x,y)= (-5* 7/4, 3*7/4)
P'(x,y) = (-35/4 , 21/4)
P'(x,y) = (-8.75, 5.25)..
Thus the ordered pair of P'=(-8.75, 5.25)....
B) 144,349 < 144,439 < 145,003
145,003 is greater than both 144,349 and 144,439 because of the 5 in the thousands place being greater than a 4 in the thousands place.
144,439 is greater than 144,349 because a 4 in the hundreds place is greater than the 3 in the hundreds place.
If you're trying to solve for x, you need to use the quadratic formula.
Plug in the numbers from the standard form of a quadratic equation
(which is
)
From here, this solves down to
Take the square root of 196, which is 14
Now, you can solve for both the + and - variations on the equation.
The solutions to your equation are 1.5 and 5/8 (probably)
- The length of a side "a" and the perimeter "2a + 2b" are not proportional.
- The length of a side "a" and the area "ab" are proportional.
<h3>How to calculate the perimeter of a rectangle?</h3>
Mathematically, the perimeter of a rectangle can be calculated by using this formula;
P = 2(L + W)
Assuming the length of the rectangle is "a" and the width is "b"
P = 2(a + b)
P = 2a + 2b
Therefore, the length of a side "a" and the perimeter "2a + 2b" are not proportional.
<h3>How to calculate the area of a rectangle?</h3>
Mathematically, the area of a rectangle can be calculated by using this formula:
A = LW
A = ab
If y = kx, k is a constant, and then y is proportional to x.
Therefore, the length of a side "a" and the area "ab" are proportional.

Answer:
I think the error is that the variable x came before the whole number 2.
