Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes
r-ruslan [8.4K]

Answer:

The equation has two zeros because the discriminant is greater than 0.

Step-by-step explanation:

3x^2 – 7x + 4

a=3   b = -7   c=4

The discriminant is

b^2 -4ac

(-7)^2 - 4(3)(4)

m = 54 \:  \: degrees

n = 144 \:  \: degrees

Step-by-step explanation:

k = 36(vertically \:  \:  \: \\  opposite \:  \:  \: angles)

90 + m + 36 = 180 \\ 126 + m = 180 \\ m = 180 - 126 \\ m = 54 \:  \: degrees

90 + m = n \\ 90 + 54 = n \\ 144 \:  \: degrees = n

How many groups of 60 equal 300
hichkok12 [17]
Okay, ask yourself this : how many times does 6 goes into 30?

6 and 1 = 6
6 and 2 = 12
6 and 3 = 18
6 and 4 = 24
6 and 5 = 30

6 goes into 30 a number of 5 times. And so that means that :

60 and 1 make 60.
60 and 2 make 120
60 and 3 make 180.
60 and 4 make 240
60 and 5 make 300

FIVE (5) groups of 60
make 300.
