Can a triangle have side lengths 3,13, and 7

Elan Coil [88]

No. This is because the two smaller lengths must be greater than the largest length (7+3=10) this is less than 13 meaning the triangle won’t work

A line with a slope of -7 passes through the points (u,0) and (8,-7) what is the value of u?

laila [671]

Answer:

u = 7

Step-by-step explanation:

Using the slope intercept formula:

$\frac{y2 - y1}{x2 - x1} = slope$

Substitute our values from the points and the known slope:

$\frac{-7 - 0}{8 - u} = -7$

Now we multiply both sides by (8 - u) to isolate the x:

(8-u) x $\frac{-7}{8 - u}$ = -7 (8 - u)

Next we add 56 to both sides:

-7 = -56 + 7u

Finish off by dividing both sides by 7:

7u = 49

u = 7
