You can use the distance formula to find the distance between any two points ion the plane. In this case, look carefully at the coordinates:
R(-1, 7) and T(-7, 7), Notice they both have y-coordinate 7. That means they are both on the same horizontal line. To find their distance, just subtract -7 from -1 and take the absolute value.
|-1 - (-7)| = |-1 + 7| = |6| = 6
The distance is 6 units
6/4 =rise/run
3/2 if it was simplified
Since the ratio is 1 to 1.5, the measurement 30 inches must correspond to 1. Thus multiply 1.5 by 30.
30*1.5 = 45
Your answer should be 45. An alternate way could be to go through all of them but for me I personally prefer this way as it is much faster and easier. Hope this helps!
Answer:
<em>Each son received from their mother $287.50</em>
Step-by-step explanation:
3(x - 275) = x - 250
2x = 825 - 250
<em>x = 287.50 </em>
$287.50 - $275 = $12.50
<u><em>Check the answer:</em></u>
After spending the older son has $12.50
$287.50 - $250 = $37.50
After spending the younger son has $37.50
$37.50 ÷ $12.50 = 3 times
Answer:
y=2/3x-2
Step-by-step explanation:
A linear equation is in the form of y=mx+b
You need to find the slope and y-intercept.
The slope is 2/3 Up 2, over 3 to the right.
The y-intercept is (0,-2)
So the equation would be, y=2/3x-2
Hope this helps :)
