Answer:

<em>(30, 0) and (0, 50)</em>

Step-by-step explanation:

( 0 , y ) are coordinates of y-intercept.

( x , 0 ) are coordinates of x-intercept.

25x + 15y = 750

25(0) + 15y = 750 ⇒ y = 50

( 0 , 50 ) are coordinates of y-intercept.

25x + 15(0) = 750 ⇒ x = 30

( 30 , 0 ) are coordinates of x-intercept.

M&lt;p= 21x+25 and m &lt;n= 675x-27/3
VladimirAG [237]

∠n and ∠p are supllementary angles, therefore m∠n + m∠p = 180°.

m\angle p=21x+25\\\\m\angle n=\dfrac{675x-27}{3}=\dfrac{675x}{3}-\dfrac{27}{3}=225x-9

therefore

(21x+25)+(225x-9)=180\\\\(21x+225x)+(25-9)=180\\\\246x+16=180\qquad|-16\\\\246x=164\qquad|:246\\\\x=\dfrac{164}{246}\\\\x=\dfrac{2}{3}

m\angle p=21x+25

substitute

m\angle p=21\cdot\dfrac{2}{3}+25=7\cdot2+25=14+25=39^o

m\angle n=225x-9

substitute

m\angle n=225\cdot\dfrac{2}{3}-9=75\cdot2-9=150-9=141^o

I need help!!<br> 23=x-9;x=14
soldier1979 [14.2K]

I'm not quite understanding what your question is.

If  23 = x - 9 , then  x = 32 , not  14.
