Solve the system of equations. y= 3x y= x2-10

Mathematics
1 answer:

Answer:

(-5, 2) and (2, 6)

Step-by-step explanation:

Use the substitution method. We know that y = 3x and y = x^2 - 10, so we can set them equal to one another.

3x = x^2 - 10

x^2 - 3x - 10 = 0

Use the quadratic equation to solve for x.

x = - 5, 2

Now solve for y using these two values of x by substituting it back into the equations.

y = - 15,  6

In coordinate form, (-5, 2) and (2, 6)

I need help with multiplying and dividing powers
Tamiku [17]
You need to know these two formulas:

\huge a^b \times a^c = a^{b+c}\\\\\huge \frac{a^b}{a^c}=a^{b-c}

For example,

5^2 \times 5^3 = 5^{2+3} = 5^5

\frac{2^6}{2^4} = 2^{6-4} = 2^2

What is the correct answer of 1/3
serious [3.7K]
The correct answer of 1/3 is the decimal form of it which is 0.3 repeated (you can put a line on top of the 3). If not just leave it as 1/3 it is simplified as a fraction.
