∠AXY=∠XBC=55°(corresponding angles)

XB=XC⇒ΔXBC is isosceles, so ∠XBC=∠XCB=55°

The sum of all the angles in a triangle is 180°⇒

55°+55°+∠BXC=180°

∠BXC=70°

What is the value of X on this triangle?

Nonamiya [84]

$\bf (x-4)+(3x)+100=180\implies x-4+3x+100=180 \\\\\\ 4x+96=180\implies 4x=84\implies x=\cfrac{84}{4}\implies x=21$

Is the graph shown at right the graph of -2x + 5y = 20? yes or no? explain your thinking

zimovet [89]

Yes

Rewrite the equation in slope intercept form.
First add 2x to both sides:
5y = 2x + 20
Divide both sides by 5
y = (2/5)x + 4

Based on this equation, the y-intercept is 4, which is true for the graph. The slope is 2/5, which is also true for the graph, seeing as how there are points at (-5,2), (0,4), and (5,6). Between each point you go 2 up and 5 to the right.
