The triangle has side lengths 10cm, 24cm, and 28cm, is it a right triangle? Explain please i dont understand
Nitella [24]

In every right triangle, if you add up the squares of the two
shorter sides, you get the square of the longest side. If you
don't then it's not a right triangle.

10² = 100
24² = 576

100 + 576 = 676

676 is the square of 26. 
It's NOT the square of 28.

So 10 - 24 - 28 is not a right triangle.

Write the equation of the line in fully simplified slope-intercept form.
Lina20 [59]

Answer:

y=-6x+2

Step-by-step explanation:

Hi there!

Slope-intercept form: y=mx+b where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0)

<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>

m=\displaystyle \frac{y_2-y_1}{x_2-x_1} where two points that fall on the line are (x_1,y_1) and (x_2,y_2)

Given the graph, we determine which points we could use. For example, we could use the two points (0,2) and (1,-4):

m=\displaystyle \frac{-4-2}{1-0}\\\\m=\displaystyle \frac{-6}{1}\\\\m=-6

Therefore, the slope of the line is -6. Plug this into y=mx+b:

y=-6x+b

<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>

Recall that the y-intercept occurs when x=0. Given the point (0,2), we know that the y-intercept is 2. Plug this into y=-6x+b:

y=-6x+2

I hope this helps!

Find factors of 15y^2-50y+35=
bazaltina [42]
First, factor out the common factor 5.

<span>15y^2-50y+35 =

= 5(3y^2 - 10y + 7)

Now we need to factor the trinomial.
3 can be factored as 3 * 1
7 can be factored as 1 * 7 or (-1) * (-7)
Since the middle term is negative, we need to use -1 and -7 as the factors of 7

= 5(3y - 7)(y - 1)
