gayaneshka [121]

Since the lines are parallel their slopes are equal. So, the equation is y=4x+b
Now we need to find the y-intercept, which is b.
Now, Plug in point p to find b:
3=4*(-1)+b
b=3+4=7
The equation is: y=4x+7

Answer:

$\displaystyle m^{\frac{35}{12}}n^{-\frac{28}{15}}=\frac{m^{\frac{35}{12}}}{n^{\frac{28}{15}}}$

Step-by-step explanation:

The relevant rule of exponents is ...

(a^b·c^d)^e = a^(be)·c^(de)

Then ...

(m^(5/4)·n^(-4/5))^(7/3) = m^(5/4·7/3)·n^(-4/5·7/3)

= m^(35/12)·n^(-28/15)

Since you want positive rational exponents, you can write this as ...

= m^(35/12)/n^(28/15)

Saydi is buying a pair of jeans that regularly cost $60. They are on sale for 40% off. If the tax rate is 9%,what is the sale pr

Karo-lina-s [1.5K]

Answer:

$39.24

Step-by-step explanation:

Let's determine the sale price before tax:

0.40($60) = $24 is the discount, so

the sale price is $60 - $24, or $36.

Multiplying this result by 1.09 results in the total price, including tax. It is $39.24.
