Answer:
X1= -1, X2= 2
Step-by-step explanation:
find the x-intercept/zero
hope this helps:)))
I just want to reccomend desmos, it really helped me with graphing because im not so good at it
But what I got is:
x-4y=-18
x=-18+4y
Root(-18,0)
Y-intercept: (0, 9/2)
Answer:
c (6)
Step-by-step explanation:
by the corresponding angles postulate, the angle above 20x-5 will be 65°.
20x - 5 + 65 = 180 <em>they are supplementary angles (angles that add up to 180°)</em>
20x + 60 = 180
20x = 120
x = 6

Answer:
The correct option is A.
Step-by-step explanation:
If a line passes through two points
and
, then the equation of line is

Let y be the profit (in millions) after x years.
From the given graph it is clear that the line passes through the point (1,-100).
The company paid for these costs and made combined profits of $80 million after 4 years. It means the graph passes through the point (4,80).
The line passes through (1,-100) and (4,80). So, the equation of line is




Subtract 100 from both sides.


The function form is

Therefore, the correct option is A.
