400. 20×20=400 Its just like 2×2 but adding 2 more 0's. Why you should add the two 0's is because theres only one 0 at the end of 20 but there 2 20's which makes it 400.

Consider the function f(x)=-2x+5 what is f(5) enter your answer in the box
Oliga [24]

The value of f(5) is f(5)=-5

Step-by-step explanation:

The function is f(x)=-2x+5

To find f(5) substitute x=5 in f(x)=-2x+5

f(5)=-2(5)+5

Multiplying the terms, we get,

f(5)=-10+5

Adding the terms, we get,

f(5)=-5

Thus, the value of f(5) is f(5)=-5

egment AB falls on line 2x − 4y = 8. Segment CD falls on line 4x + 2y = 8. What is true about segments AB and CD?
jolli1 [7]

Answer:

The line segments AB and CD are perpendicular to each other.

Step-by-step explanation:

Segment AB falls on line 2x − 4y = 8.

Rearranging the equation into slope-intercept form we get,  ............. (1)

Therefore, slope of the line segment AB is

Now, the segment CD falls on line 4x + 2y = 8.

Rearranging the equation into slope-intercept form we get,  ............. (2)

Therefore, the slope of the line segment CD is, N = - 2

So, M × N =

Hence, we can conclude that the line segments AB and CD are perpendicular to each other

-X² + 5x - 6 = 2<br> Using the quadratic formula
Ivenika [448]

-x^2+5x-6=2\\-x^2+5x-6-2=0\\-x^2+5x-8=0\\

↝ Form into ax^2+bx+c = 0 where a > 0 (Optional)

x^2-5x+8=0 ↝ Multiply -1 for both sides.

↝ Then proceed with the Quadratic Formula.

x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula

x=\frac{-(-5)+-\sqrt{(-5)^2-4(1)(8)}}{2(1)}\\x=\frac{5+-\sqrt{25-32}}{2}\\

↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.

↝ Solution with Real Numbers  System ↝  There are no real solutions.

↝ Solution with Complex Number System ↝

x=\frac{5+-\sqrt{25-32}}{2}\\x=\frac{5+-\sqrt{-7}}{2}\\x=\frac{5+-\sqrt{7}i }{2}

Therefore, the answer for Complex Number System is (5±√7i)/2
