Answer:

When the discriminant value is zero, we get one real solution; When the discriminant value is negative, we get a pair of complex solutions; Standard Form. The standard discriminant form for the quadratic equation ax 2 + bx + c = 0 is. Discriminant, D = b 2 – 4ac. Where. a is the coefficient of x 2. b is the coefficient of x. c is a constant term.

What is the value of log(x exponent 2 y exponent 3 divided by z) when given the following:

Gekata [30.6K]

Answer:

B. 13

Explanation:

$\sf\:Given\:expression: log(\dfrac{x^2 y^3}{z} )$

Logarithm rules:

$\sf (i) \ \sf log(ab) = log(a) + log(b)\\ \\ (ii) \ log(a/b) = log(a) - log(b)\\\\ (iii) \ log(a^n) = n log(a)$

Breakdown of the expression:

$\rightarrow \sf log\left(\dfrac{x^2y^3}{z}\right)$

$\rightarrow \sf log\left(x^2\right) + log\left(y^3\right) - log(z)$

$\rightarrow \sf 2\log\left(x\right)+3\log \left(y\right)-\log \left(z\right)$

insert given values

$\rightarrow \sf 2(3)+3(2)-(-1)$

$\rightarrow \sf 13$

Let the number of games, x, and the number of rides y, For 2x + 4y = 20, what is the slope of the graph? What is the slope? (Hin

hram777 [196]

Answer:

m= -1/2, (0,5), (10,0)

Step-by-step explanation:

Let us write it in slope intercept form, y=mx +b where m is the slope:

2x+4y=20

4y= -2x+20

y= -1/2x+5

Therefore, the slope is -1/2

The y intercept can be found when we substitue 0 as x.

y= -1/2*0 +5

y=0+5

y=5

(0,5)

The x intercept can be found when we substitute 0 as y.

0=-1/2x+5

-5 =-1/2x

x= 10

(10, 0)
