Answer:

$total \: angleof \: a \: triangle = 180 \\ then \\ x + 3x - 1 + x - 19 = 180 \\ 5x - 20 = 180 \\ 5x = 180 + 20 \\ 5x = 200 \\ x = \frac{200}{5} \\ x = 40 \\ thank \: you$

Calculate the distance between points (-8,-2) and (4,3)

Kamila [148]

To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:

$\mathsf{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$

"d" represents the distance and coordinates are expressed as follows: (x, y)

Let's go to the calculations.

$\mathsf{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}\\\\ \mathsf{d=\sqrt{(4-(-8))^2+(3-(-2))^2}}\\\\ \mathsf{d=\sqrt{(4+8)^2+(3+2)^2}}\\\\ \mathsf{d=\sqrt{(12)^2+(5)^2}}\\\\ \mathsf{d=\sqrt{144+25}}\\\\ \mathsf{d=\sqrt{169}}\\\\ \underline{\mathsf{d=13}}$

The answer is 13 uc.

Solve 3x+2y-6=0 for y

2y-6=-3x

2y=-3x+6

y=-1.5x+3

So the slope of the reference line is -1.5. For two lines to be parallel they must have the same slope so our line will also have a slope of -1.5 so we have:

y=-1.5x+b, now we can solve for b given the point (0,0)

0=-1.5(0)+b

0=0+b

b=0 so our line is:

y=-1.5x
