for some real number A, the graph of the line Y=(A+1)x+8 in the standard (x,y) coordinate plane passes through (2,6). What is th

kondaur [170]

Answer:

-1

Step-by-step explanation:

The given equation has a y-intercept of 8, so goes through the point (0, 8).

If the line also goes through the point (2, 6) it has a slope of ...

(y2 -y1)/(x2 -x1) = (6 -8)/(2 -0) = -2/2 = -1

The slope of the line is -1.

_____

The value of A is -2.

Find all the zeros of the equation<br> -3x^4 + 27x^2 + 1200 = 0

guajiro [1.7K]

Answer:

$\displaystyle x=-5,\ x=5,\ x=4i,\ x=-4i$

Step-by-step explanation:

Biquadratic Equation

It's a fourth-degree equation where the terms of degree 1 and 3 are missing. It can be solved for the variable squared as if it was a second-degree equation, and then take the square root of the results

Our equation is

$\displaystyle -3x^4+27x^2+1200=0$

If we call $y=x^2$ , our equation becomes a second-degree equation

$\displaystyle -3y^2+27y+1200=0$

Dividing by -3

$\displaystyle y^2-9y-400=0$

Factoring

$\displaystyle (y-25)(y+16)=0$

It leads to these solutions

$\displaystyle y=25\ ,\ y=-16$

Taking back the change of variable, we have for the first solution

$\displaystyle x^2=25\Rightarrow x=-5,x=5$

Now for the second solution, we get imaginary (complex) values

$\displaystyle x^2=-16\Rightarrow x=4i,\ x=-4i$

Summarizing, the four solutions for x are

$\displaystyle x=-5,\ x=5,\ x=4i,\ x=-4i$

Which simplified ratio correctly compares 10,000 centimeters to 1000 meters

dangina [55]

Answer:

10000 cm to 1000 m ratio is 1:10

Step-by-step explanation:

To find : The simplified ratio correctly compares 10,000 centimeters to 1000 meters.

Solution :

To find the ratio first we make the unit same.

1 m= 100 cm

1000 m= 1000 × 100 cm

1000 m= 100000 cm

Now, to compare 10,000 cm to 1,00,000 cm

The ratio is

$\frac{10000}{100000}=\frac{1}{10}$

10000 cm to 100000 cm ratio is 1:10

or 10000 cm to 1000 m ratio is 1:10
