Answer:

=6\sqrt{3}

Step-by-step explanation:

This triangle is the same as a right triangle rotated around.

Pythagorean Theorem applies to this (because it's a right triangle)

a^{2} +b^{2} =c^{2}

36+b^{2} =144

144-36=108\\b^{2} = 108\\\sqrt{108} = 10.39\\ = \sqrt{b^{2} } \\b=10.39

x=10.39

Given a polynomial f(x), if (x + 7) is a factor, what else must be true? Help plzzz im running out of time
solong [7]
Answer: f(-7) = 0
For the factored form of f(x), if x = -7, then one of the factors will be equal to 0, since (-7 + 7) = 0. This will cause the entire y-value to be 0, because anything multiplied by 0 = 0.

Enter an inequality that represents the graph in the box.
mamaluj [8]

We know the y intercept is -6 and we know the slope is positive 4 (rise over run) so the equation is y=4x-6 if we plug in a shaded point (I would choose 0,0 for convenience reasons) 0=-6 since -6 is less than 0, the expression would be y≥4x-6

In the xy coordinate plane, the slope of a line is 4 and it passes through the point (1, 3). Find the equation of a line that is
igor_vitrenko [27]

Answer: Y=-1 or Y=-1+4

Step-by-step explanation:

<h3>Use the formula y2- y1 over x2-x1 so it should look like this 1-3 over 3-1 which is -2 over 2 then you divide that which is -1 and if you have to find one all you have to do is use one point label which is x and y so I pick (1,3) so you put 3=-1(1) once you have that you multipy so -1 times 1 is -1 so your gonna add 1 to the -1 and the three the -1 cancel out because it is a zero pair 3+1 is 4 so B=4 </h3>
