2(4a - 4b) + 4(3a + 2b)<br><br>plz solve this!!! ​
ivann1987 [24]

Answer:

2(4a - 4b) + 4(3a + 2b) = 20a

Step-by-step explanation:

2(4a - 4b) + 4(3a + 2b)

8a - 8b + 12a + 8b

8a + 12b - 8b + 8b

20a+ 0 = 20a

Thus, 2(4a - 4b) + 4(3a + 2b) = 20a

Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes
Eduardwww [97]
For ax^2+bx+c=0 the discriminant is b^2-4ac

there are 3 basic cases of what happens for different discriminants
1. if the discriminant is less than 0, then there are no real zeroes
2. if the discriminant is 0, then it has 1 zero
3. if the discriminant is greater than 0, it has 2 zeroes


so given
0=3x^2-7x+4
a=3,b=-7,c=4
thus the discriminant is (-7)^2-4(3)(4)=49-48=1
the discriminant is 1. 1 is positive, thus the equation has 2 zeroes because the discriminant is greater than 0

the answer is the equation has two zeroes because the discriminant is greater than 0

Just answer 9 and 10
grin007 [14]
Answer: (in point slope form as asked)
9: y-1=3(x-0)
10: y+3=-1(x-2)
Why?
Point slope equation: y-y1=m(x-x1)
M=slope
Y1= y for first point
X1= x for first point
9: First I found the slope but moving up 3 over 1 from point 0,1 up to point 1,4 because slope = rise/run this gave me 3.
10: I started at point 2,-3 and moved up to point 1,-2 which shows that the slope is 1, BUT it is a negative line so it’s a -1. Then because the equation for point slope is subtraction and -3 is negative it becomes addition

Hope this helps :D (comment if you need me to explain better)
