How many and what type of solutions does the equation have?

1 answer:

7 0

There are technically two solutions because the highest power of c is 2. However, when you solve the equation, you find that both answers are x=4 so you have one rational solutions

Hope this helps

Latoya gets paid by the hour. During a 20-hour week, latoya earns 120. If she works only 15 hours, how much does she earn?

Alisiya [41]

Answer:

If Latoya works 15 hours only, she will make $90.

Step-by-step explanation:

Divide the total she earns from the total amount of hours she worked to get the amount she gets per hour.

120/20 = 6

Latoya gets paid $6 per hour.

Multiply 6 with 15

15 x 6 = 90

If Latoya works 15 hours only, she will make $90.

(That's below minimum wage...)

What substitution should be used to rewrite 4x^4-21x^2+20=0 as a quadratic function?

pogonyaev

Answer:

see explanation

Step-by-step explanation:

Let u = x² ( choice of variable is flexible ), then

4u² - 21u + 20 = 0 ← expressed as a quadratic

This can now be solved for u and converted back into terms of x

Simplify the expression. Assume that all variables are positive. Exponents in simplified form should all be

Rainbow [258]

Given:

The given expression is $\frac{7^{\frac{1}{2}} \cdot 7^{\frac{3}{2}}}{7^{-3}}$

We need to determine the exponents in simplified form.

Exponents in simplified form:

Let us determine the exponent in simplified form.

Let us apply the exponent rule $\frac{x^{a}}{x^{b}}=x^{a-b}$

Thus, we have;

$7^{\frac{1}{2}+\frac{3}{2}-(-3)}$

Adding the fractions, we get;

$7^{\frac{4}{2}-(-3)}$

Cancelling the common terms, we have;

$7^{2-(-3)}$

Simplifying the exponent, we get;

$7^{2+3}$

Adding the exponent, we have;

$7^5$

Thus, the simplified form of the expression is $7^5$
