Step-by-step explanation:
it is not clear, if RT = 20 or UT = 20.
both are possible scenarios.
I assume that RT = 20 (otherwise the sub-triangle RSU is not sufficiently defined, as R could be moved outward to the left it further inward to the right, and the rest of the triangle is unchanged).
for any triangle with sides a, b, c and semiperimeter
s = (a + b + c) / 2, the height to side a is
ha = 2×sqrt(s(s-a)(s-b)(s-c))/a
in our case here
s = (20+25+17)/2 = 62/2 = 31
hRT = SU = 2×sqrt(31×(31-20)(31-25)(31-17))/20 =
= sqrt(31×11×6×14)/10 = sqrt(28,644.)/10 =
= 16.9245384...
RU² = 17² -SU² = 289 - 286.44 = 2.56
RU = 1.6 ≈ 2
Answer:
C (y=5x-7)
Step-by-step explanation:
First, you find the slope between the 2 points which is 5, then you use one of the points to form an equation.
You then find it's y=5x-7.
I think the answer would be 1.
Answer:
A few examples:
0. 0
1. Undefined
2. -3/5
3. Undefined
...
7. 493
8. 5/2
....
Learn how to find the slope below for the other problems.
Step-by-step explanation:
Slope is the rate of change for a linear function. It is found by subtracting the y values of two point on the line and dividing that difference by the difference of the x values of the points.
It can also be found using the formula y=mx+b known as the slope intercept form.
Here are a few examples:
0. This is a horizontal line which always has slope 0.
1. This is a vertical line which always has slope undefined.
2. Find two points that cross through a grid line intersection The line appears to cross them at (5,3) and (0,6). Count the unit squares between the two by counting up 3 and over to the left 5. Because it is left it is negative. The slope is -3/5
3. To find the slope, use the slope formula:
Since we can't divide by 0, it is undefined.
7. y=493x-257 follows the formula y=mx+b where m is the slope. m=493. The slope is 493.
8. Covert the equation into y=mx+b by rearranging the terms using y=mx+b.
5x-2y=48
-2y=48-5x
y=5/2 x -24
So the slope is 5/2.
