1) Answer: The part of the quadratic formula tells us whether the quadratic equation can be solved by factoring is b^2-4ac
2) 4x^2+6x+2=0
ax^2+bx+c=0; a=4, b=6, c=2
b^2-4ac=(6)^2-4(4)(2)=36-32
b^2-4ac=4
Answer: b^2-4ac=4
Answer:
p = 2.7x - 20
p(90) = $223
Step-by-step explanation:
revenue → f(x) = 3x ,where x is the number of downloads.
the statement “Your profit p is $20 less than 90% of the revenue for x downloads”
<u><em>means</em></u>

<u><em>means</em></u>
<u><em></em></u>
<u><em>means</em></u>

<u><em>means</em></u>

<u><em>means</em></u>

………………………………
the profit for 90 downloads :
= p(90)
= 2.7×(90) - 20
= $223
Answer:
n=5, m = 4
Step-by-step explanation:
It is a parallelogram so m+8 = 3m and 2n-1 = 9
A. equation: y = -3x - 2
B. y-intercept: -2
<em><u>Solution:</u></em>
Given that,
<em><u>Write the equation 12x = - 4y - 8 in slope-intercept form</u></em>
The slope intercept form is given as:

Where,
m is the slope and "c" is the y intercept
From given

Thus the slope intercept form is found
Comparing with y = mx + c ,
c = -2
Thus the y intercept is -2
The answer to the equation is 15
