Answer:
Step-by-step explanation:
(7x-3)(12x-7)
we are solving for x and we are multiplying.
we start with the x's 7x*12x= 84x
-3*-7=21
so now we have
84x+21=0
the 0 is a placer for answering the question
we minus 21 to both sides
84x=-21
now we divide
84/-21= -4
x=-4
Y = 4/5x + 30
4/5 because the slope is 4 up, 5 right. 30 is the y-int
angles x y z are all acute because they are less than 90 degrees
