Answer:

Given equation have two solutions.

x = -\frac{5}{2} and -\frac{8}{3}

Right option is (D)

Step-by-step explanation:

We have given,

6x^{2} +40=-31x

we can rewrite this equation in the form given as:

6x² + 40 + 31x = 0

or 6x² + 31x + 40 = 0

On solving this quadratic equation, we get :

x = -\frac{5}{2} and -\frac{8}{3}

That means, given equation have two solutions.

Right option is (D)

Answer:

Option D is correct, i.e. two solutions.

Step-by-step explanation:

Given the equation is 6x² + 40 = -31x.

Rearranging the terms:- 6x² +31x +40 = 0.

Then a = 6, b = 31, c = 40.

Finding Discriminant as follows:-

D = b² -4ac

D = 31² -4*6*40

D = 961 - 960

D = 1

If we have positive value of D, then it has two real solutions.

Hence, option D is correct, i.e. two solutions.

Find the product of (5.2 · 10-6) and (8 · 103).
sertanlavr [38]
The first one is 46 because according to the order of operations in this problem you have to multiply first so you do 5.2 times 10 which is 52 . Next do 52 - 6 = 46. Next multiply 8 times 103 which is 824. Then you multiply the two (46 times 824) and you get 37904

Find the equation of the line shown.
Luda [366]

Answer:

y = -x + 9

Step-by-step explanation:

✔️Find the slope using (9, 0) and (7, 2):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 0}{7 - 9} = \frac{2}{-2} = -1

Slope (m) = -1

✔️Find the y-intercept (b):

The line intercepts the y-axis when y = 9. Therefore, y-intercept (b) = 9

✔️Substitute m = -1 and b = 9 into y = mx + b

Thus,

y = -1(x) + 9

y = -x + 9
