Answer:

$\frac{7}{10} y$

Step-by-step explanation:

To add fractions with the same denominator, simply add the numerators:

$\frac{a}{b} + \frac{c}{b} = \frac{a+c}{b}$

So:

$\frac{3}{10} y+\frac{4}{10} y=\frac{7}{10} y$

Tell whether xy is positive or negative. If x is negative and y is positive, the product is

mamaluj [8]

Negative. A negative number times a positive number is equal to a negative number. X multiplied by Y is a positive.

what is the maximum volume of water a hamster bath can hold with a depth of 1 2/3, a length of 2 1/3 inches, and a width of 2 in

8_murik_8 [283]

The volume is 70/9 or 7 7/9.
=========================================
$\frac{5}{3} \times \frac{7}{3} \times \frac{2}{1} = \frac{70}{9}$
$\frac{70}{9} = 7 \frac{7}{9}$
$l \times w \times h = v$

Solve for x in the equation x2-8x+41=0

Alinara [238K]

Answer:

d) 4 ± 5i

Step-by-step explanation:

Here we have to use the quadratic formula.

x = $\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}$

In the given equation x^2 - 8x + 41 = 0, a =1, b = -8 and c = 41

Now plug in the given values in the above formula, we get

x = $\frac{-(-8) +/- \sqrt{(-8)^2 - 4*1*41} }{2*1}$

Simplifying the above, we get

x = $\frac{8 +/- \sqrt{64 - 164} }{2}$

x = $\frac{8 +/- \sqrt{-100} }{2}$

[√-100 = √-1 *√100 = i*10 = 10i] because the value of √-1 = i]

x = (8 ± 10i )/2

Now dividing by 2, we get

x = 4 ± 5i

The answer is d) 4 ± 5i

Hope you will understand the concept.

Thank you.

10.3 Question 5. 6. Explain your answer for both questions....

AVprozaik [17]

First it is reflected in the x axis (beacuse the x value becomes negative but the y values stays the same)
second its dilated by a factor of a half ( the sides of the figure are reduced by a half)
then its translated 2 units to the left and 2 units upwards
