<h3>
Answer: (3, -2)</h3>
Explanation:
Your teacher wants you to find the midpoint. This is the point that is in the middle of the two given points. Let's call this M. So the distance from M to (5,-5) will be the same as the distance from M to (1,1)
The x coordinates of (5,-5) and (1,1) are 5 and 1 respectively.
Add them up: 5+1 = 6
Divide by two: 6/2 = 3
The x coordinate of the midpoint is x = 3
Repeat for the y values -5 and 1
Add: -5+1 = -4
Divide in half: -4/2 = -2
The y coordinate of the midpoint is y = -2
So the midpoint is M = (x,y) = (3,-2)
If you were to use the distance formula, you would find that
distance from (5,-5) to (3,-2) = distance from (3,-2) to (1,1)
This is what it means to be "equidistant" (aka "equally distant")
Answer:
19 and 20
Step-by-step explanation:
Let x be the larger number
x - 1 + x = 4x - 41
We can combine like terms and isolate x:
2x - 1 = 4x - 41
2x = 40
x = 20
20 - 1 = 19
We have that
x²<span> + 3x = 24
</span><span>Group
terms that contain the same variable
</span>(x² + 3x) = 24
<span>Complete
the square. Remember to balance the equation by adding the same constants
to each side
</span>(x² + 3x+2.25) = 24+2.25
Rewrite as perfect squares
(x+1.5)² = 26.25
(+/-)[x+1.5]=5.12
(+)[x+1.5]=5.12----> x=5.12-1.5---> x=3.62
(-)[x+1.5]=5.12-----> x=-1.5-5.12---> x=-6.62
the answer is<span>
3.62, –6.62</span>
Yeah it’s defiantly then first but maybe
Answer:
x = 125.44
Step-by-step explanation:
you multiply both side by 7
so 7 • 17.92 = 7 • x/7
125.44 = x
