The value of x will be -3.
The slope formula is y2-y1/x2-x1
In this case fill in using the two sets of numbers (x is still missing).
-6-1, which equals -7.
X-4, which you have to figure out mathematically.
Well in order to get a slope of 1 -7 has to be divided by itself, which is still -7.
What subtracted by 4 equals -7?
That would be -3.
Answer:
She used the incorrect area formula.
She converted the mixed number to an improper fraction incorrectly.
She multiplied incorrectly.
Step-by-step explanation:
The area of a parallelogram is
A = bh not A = 1/2 bh
She started with the wrong formula
A = 7 2/5 * 2
Change to an improper fraction
The improper fraction is 37/5 not 35/5
A = 37/5 *2
She multiplied incorrectly
A = 74/5

Answer:
The distance between A and A' is:
![distance=\sqrt{20}](https://tex.z-dn.net/?f=distance%3D%5Csqrt%7B20%7D)
Step-by-step explanation:
Notice that point A' after the given translation becomes: (-2+4, 3+2) = (2, 5),
So one can calculate the distance between A (-2, 3) and A' (2, 5) using the distance formula:
![distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\distance=\sqrt{(2-(-2))^2+(5-3)^2} \\distance=\sqrt{(4))^2+(2)^2} \\distance=\sqrt{(16+4} \\distance=\sqrt{20}](https://tex.z-dn.net/?f=distance%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D%5C%5Cdistance%3D%5Csqrt%7B%282-%28-2%29%29%5E2%2B%285-3%29%5E2%7D%20%5C%5Cdistance%3D%5Csqrt%7B%284%29%29%5E2%2B%282%29%5E2%7D%20%5C%5Cdistance%3D%5Csqrt%7B%2816%2B4%7D%20%5C%5Cdistance%3D%5Csqrt%7B20%7D)
Answer:
x = 2
Step-by-step explanation:
x + 5 = 2x + 3 ( subtract x from both sides )
5 = x + 3 ( subtract 3 from both sides )
2 = x
