3x-30=0why does it equal 0 and how would I solve for it

Mathematics
1 answer:
agasfer [191]3 years ago
5 0

Answer: the reason why 3x - 30 = 0 is because x = 10

Step-by-step explanation:

3x - 30 = 0

first we try to get the value of x

so

3x = 30

x = 30/3

x = 10

so the reason why 3x - 30 = 0 is because x = 10

to confirm this

we substitute the value of x=10 into the equation

3x - 30 = 0

3*10 - 30 = 0

30 - 30 = 0

Find the slant height for a right circular cone with a radius of 3 and a height of 5.
babymother [125]

Answer: l = \sqrt{34}

Step-by-step explanation:

The slant height of a cone is given by

l = \sqrt{h^{2}+r^{2}  }

h= 5

r = 3

Therefore :

l = \sqrt{5^{2}+3^{2}  }

l= \sqrt{25+9}

l = \sqrt{34}

Solve using quadratic formula<br> 5x^2-4x+3=0
Semenov [28]

Answer:

Impossible

Step-by-step explanation:

In 5x^2-4x+3=0, standard form, substitute these values in the quadratic formula:

a = 5; b = -4; c = 3

The quadratic formula is x = \frac{ -b ± \sqrt{b^{2} - 4ac}}{2a}

(ignore the weird capital A)

Substitute a b and c:

x = \frac{-(-4) ± \sqrt{(-4)^{2} - 4(5)(3)}}{2(5)}

Simplify:

x = \frac{4) ± \sqrt{16 - 60}}{10}

Because \sqrt{16-60} is the square root of a negative number, the answer would be imaginary.

Therefore, there are not solutions to this equation.

A solution is the same as the roots or zeroes, where the graph would cross the x-axis when graphed.

The graph never meets the x-axis. It looks like this:
