ss7ja [257]

Answer:

<h2>no real solution</h2>

Step-by-step explanation:

$-3x^2-4x-4=0\qquad\text{change the signs}\\\\3x^2+4x+4=0\\\\\text{use the quadratic formula:}\\\\\text{for}\ ax^2+bx+c=0\\\\\text{if}\ b^2-4ac0,\ \text{then an equation has two solutions:}\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

$\text{We have}\ a=3,\ b=4,\ c=4.\\\\\text{Substitute:}\\\\b^2-4ac=4^2-4(3)(4)=16-48=-32$

Suppose the body length L in inches of a baby snake is given by L(m) = 1.5 + 2m, where m is the age of the snake in months until

Inessa [10]

L(m) = 1.5 + 2m.....when snake is 8 months..m = 8
L(8) = 1.5 + 2(8)
L(8) = 1.5 + 16
L(8) = 17.5 inches <==

L(m) = 1.5 + 2m....length is 25.5.....L(m) = 25.5
25.5 = 1.5 + 2m
25.5 - 1.5 = 2m
24 = 2m
24/2 = m
12 = m ....12 months <==

You pay sales tax on your purchases at the rate of 0.07. What fraction of your money is this? Remember to reduce your fraction

Gemiola [76]

Answer:

This is $\frac{7}{100}$ of your money.

Step-by-step explanation:

We have a decimal number, and we want the answer to be a fraction. To transform a decimal number into a fraction, we multiply both the numerator and the denominator by 10 until none of them have decimal parts. So

$0.07\times \frac{10}{10} = \frac{0.7}{10}\times \frac{10}{10} = \frac{7}{100}$

This is $\frac{7}{100}$ of your money.
