Answer:

x = 5i

x = -5i

Step-by-step explanation:

x² + 25 = 0

x² = 0 - 25

x² = -25

x = √-25

x = 5i

x = 5i   x =-5i

Step-by-step explanation:

x^2+25=0

Rewriting

x^2 - (-25)=0

Writing as the difference of squares

a^2 - b^2= (a-b) (a+b)

where a = x and b = (sqrt(-25)) =±5i

( x-5i) ( x+5i) =0

Using the zero product property

x-5i =0    x+5i =0

x = 5i   x =-5i

Which of the following is the correct slope-intercept form of the equation -4x + 2y = 14? y = 4x + 14 y = -4x + 14 y = 2x + 7 y
DerKrebs [107]

Answer:

Step-by-step explanation:

The slope intercept form equation of a straight line is expressed as

y = mx + c

Where

m represents slope

c represents y intercept.

Comparing the given equations with the slope intercept form equation,

2) y = 4x + 14 is in the slope intercept form. Its slope is 4 and the intercept is 14.

3) y = -4x + 14 is in the slope intercept form. Its slope is - 4 and the intercept is 14.

4) y = 2x + 7 is in the slope intercept form. Its slope is 2 and the intercept is 7.

5) y = -2x + 7 is in the slope intercept form. Its slope is - 2 and the intercept is 7.

If the bathtub holds a total of 46.2 gallons, how many minutes would it take to fill the entire tub? Write an equation in one va
sergejj [24]

Answer:

It will take 2.8 minutes

Step-by-step explanation:

Given

x \to Minutes

y \to Gallons

See attachment for complete question

Required

Time to fill the tube with 46.2 gallons

The attached table is a represents a direct proportional relationship between x and y.

This relationship is:

y = kx

Where k is the constant of proportionality.

When (x,y) = (1,16.5), we have:

16.5 = k*1

16.5 = k

k=16.5

So, we have:

y = kx

y = 16.5x

To calculate the required time to fill 46.2 gallons, we make x the subject

x = \frac{y}{16.5}

Where

y =46.2

x = \frac{46.2}{16.5}

x = 2.8
