Answer:
11, 60.61
Step-by-step explanation:
this is the only set that fits a^2 +b^2=c^2
you square the first two numbers, add them together. Then you take the square root of that sum. This number must equal the third number for it to be a triple.

<h3><u>The value of y is -2.5</u></h3><h3><u>The value of x is -2.</u></h3>
x - 8y = 18
-16x + 16y = -8
We can multiply each term in the first equation by 2 to better assist this elimination.
2x - 16y = 36
Now, we can use elimination.
Add equations together.
-14x = 28
Divide both sides by -14
x = -2
Now that we have a value for x, we can solve for y.
-2 - 8y = 18
Add 2 to both sides.
-8y = 20
Divide both sides by -8
y = -2.5
Answer:
Brady did not distribute the -1 correctly.
Step-by-step explanation:
The given expresion is
Recall that for all real numbers a, b, and c, the distributive property says that:
We apply this property to get:
But Brady said it is equivalent to 1.3-4.5
Hence Brady did not apply the distributive property correctly.
Answer:
B(6,-1)
Step-by-step explanation:
mid point of AB = (1,3)
MID POINT FORMULA=(x1+x2/2 , y1+y2/2)
1=x1+x2/2 , 3=y1+y2/2
2= -4 + x2 , 6 = 7 +y2
x2=6, y2=-1
