Answer:
2 imaginary roots
Step-by-step explanation:
The discriminate is the portion of the quadratic equation under the square root
D = b^2 - 4ac
D = 8^2 - 4(2)(16)
D = 64 - 128
D = -64
Since the discriminate is negative the square root will be imaginary
and there will be 2 of them
2 imaginary roots
Answer:
Total sales= 10000
Step-by-step explanation:
Given data
monthly salary=$1500
commission on total sales= 5.75%
gross pay=$2,075
Firstly, let us deduct the salary
2075-1500=$575
so Saiah earned a commission of $575
let the total sales be x
so 5.75% of x= $575
5.75/100*x=576
0.0575x=575
x=575/0.0575
x=10000 sales

Nov 20, 2016 · If we assume that initially Number of red counter is 1 Number of blue counter is 3 Now to make ratio reverse you need to add 8 more red counters so that ratio becomes 9:3=3:1
Step-by-step explanation:
f(x) = 4x + 3
That's one-to-one, a linear function that will give a different f(x) for each different x.
For the inverse let's swap x and y and solve for y
x = 4y + 3
x - 3 = 4y
y = (x- 3)/4
That's the inverse,
Answer: (x- 3)/4, second choice
The domain and range of the inverse is all real numbers. It's two lines; I'll leave the graphing to you.
