Question

Mathematics
1 answer:
tester [92]2 years ago
6 0

Answer:

Ø.

Step-by-step explanation:

Given the equation 7x^2 = -14. We are to find the value of x;

7x^2 = -14.

Divide both sides by 7

7x^2/7 = -14/7

x² = -2

Square root both sides

√x² = ±√-2

x = ±√2 i

The value of x is (-√2 i, √2 i)

Since there values is a complex values, hence there is no real solution. The answer is Ø.

Is respect more important or is money more important?Explain Why
antiseptic1488 [7]
Respect is definitely more important than money because money is printed everyday there is tons of it. But respect is hard to get nowadays and is even easier to lose. Have you ever stopped and thought about the meanest thing that you have said to your friend? To someone online? Does that sound like respect to you?

If f(x) varies directly with x and f(x) = 4 when x = 12, then what is the value of f(x) when x = 60?
ANTONII [103]
ANSWER

f(60)=3\times60=180

EXPLANATION
We were given that
f(x)
varies directly as
x.

We can write this mathematically as,

f(x) \propto \: x.

This implies that,

f(x) = kx
where k is the constant of variation.

f(4)=4k

This implies that,

4k=12

k = 3

The equation becomes

f(x)=3x

When x=60

f(60)=3\times60=180
