lianna [129]3 years ago
4 0

Answer:

D=41

Step-by-step explanation:

4x² + 3x − 2 = 0

To find the discriminant we need to use formula

D = b² - 4 ac

Quadratic equation in general form:

ax² + bx + c = 0

4x² + 3x − 2 = 0

We can see that

a = 4, b = 3 , c = -2

So, D = 3² - 4*4*(-2) = 9 +32 = 41

D = 41 is positive , so given equation has 2 real solutions.

If D = 0 , there is  1 real solution.

If D< 0 , then there is no real solutions.

Is 9-8x=y proportional
andrew-mc [135]

Answer:

No, proportional relations are of the form,

y = mx

Step-by-step explanation:

The given equation is

9 - 8x = y

This is an equation in the form:

y = mx + c

since we can rewrite to get:

y =  - 8x + 9

This equation has a non-zero y-intercept and does not pass through the origin.

A proportional relation, will have a zero y-intercept and pass through the origin.

Therefore a proportional relation is of the form,

y = mx
