Question 3

Mathematics
1 answer:
crimeas [40]3 years ago
8 0

Answer:

D = 141

Step-by-step explanation:

The given quadratic equation is

5x^2+9x=3\\\\5x^2+9x-3=0.

It is required to find the value of the discriminant. The value of discriminant  of any quadratic equation is given by :

D=b^2-4ac

Here, a = 5, b = 9 and c = -3

On plugging all the values, we get :

D=(9)^2-4\times 5\times (-3)\\\\D=141

So, the value of discriminant for y is 141.

What is an equation of the line that is parallel to y=9−5x and passes through (0, 8) ?
TEA [102]

Answer:

y = -5x Y8  

Step-by-step explanation:

Parallel lines have the same slope.

Your function is

y = 9 − 5x = -5x+ 9

slope = -5

The parallel line

The line must have slope = -5 and include (0, 8), so

8 = -5×(0) + b

8 = 0 + b

b = 8

The equation for the parallel line is

y = -5x + 8

In the diagram below, the red line is the graph of y = 9 -5x.

The parallel blue line is the graph of y = -5x + 8.
