Answer:

x = 19

Step-by-step explanation:

∠ YWX = ∠ ZYW = 2x ( alternate angles )

The sum of the 3 angles in Δ WXY = 180° , that is

3x - 5 + 2x + 90 = 180

5x + 85 = 180 ( subtract 85 from both sides )

5x = 95 ( divide both sides by 5 )

x = 19

Graph the equations to solve the system. <br> y=3x+3<br> 1/3y+x+1

riadik2000 [5.3K]

Given equation is y=3x+3 and $\frac{1}{3}y=x+1$

Let's simplify the 2nd equation $\frac{1}{3}y=x+1$ before we can start graph so that calculation will be easy

$\frac{1}{3}y=x+1$

multiply both sides by 3 to cancel out fractions

$3*\frac{1}{3}y=3*x+3*1$

y=3x+3

which is exactly same as the first equation so graph of both will be exactly same and solution will be infinitely many solutions.

y=3x+3 has y-intercept 3 so first point will be (0,3). Slope is 3 so rise 3 unit up then 1 right and graph the new point.

Which expression gives the distance between the points (5, 1) and (9, -6)?

Vesna [10]

So the distance formula: d = rad (x2 - x1)^2 + (y2 - y1)^2
it doesn't matter what order you do, you just have to make sure it's a y coordinate for y and an x coordinate for x.
rad (9-5)^2 + ((-6)-1)^2
rad 4^2 + (-7)^2
rad 16 + 49
rad 65
