Answer:
positive
Step-by-step explanation:
the discriminant of the function is postive.
because from the graph we notice that it has 2 intercepts on x-axis, which means the function has 2 real solution when y=0
that implies the discriminant is positive.
if 
we have 2 distinct real solution
if 
we have no real solution but 2 complex solutions
if 
we have 2 identical real solution
20/4 = 5
$5 is the cost of 1 shirt.
Y=10x, 10 is the amount of money Miranda earns per hour , x is the amount of hours she works, y is the total amount of money she earns.
For Tommy’s earnings, use slope formula, which is y=y2-y1/x2-x1, take two random points from the table, (4,32) and (5,40)
(4,32) is (x1,y1). (5,40) is (x2,y2)
40-32/5-4= 8/1
The answer is 8. y=8x
Miranda earns more money per hour than Tommy.
Answer:
D
Step-by-step explanation:
Recall that the area of a triangle is given by:
In this case, the base is <em>x</em> and the height is <em>y</em>. Hence:
We can write the following ratios:
Solve for <em>x</em> and <em>y</em>:
Substitute:
And simplify. Hence:
In conclusion, our answer is D.
