Answer:

-8r/s

Step-by-step explanation:

r /s - 9r /s

The denominator is the same so subtract the numerators

r - 9r

-8r

Put this back over the denominator

-8r/s

Answer:

simplest Form (fractions) A fraction is in simplest form when the top and bottom cannot be any smaller, while still being whole numbers.

Step-by-step explanation:

To simplify a fraction: divide the top and bottom by the greatest number that will divide both numbers exactly (they must stay whole numbers). hope this helps you :)

What is the solution to the following system of equations? y = −x^2 − 5x − 4 y = −x^2 + 9x − 18

nika2105 [10]

Answer:

X=1 Y= -10

Step-by-step explanation:

$Y=-x^{2} -5x-4 equation 1 \\Y=-x^{2} + 9x-18$ equation 2

using equation 1, we substitute in equation 2

We have

$-x^{2} -5x-4 = -x^{2} + 9x-18\\-14x=-14\\x=1\\$

so, we substitute the X value in equation2

we have>

$y=-(1^{2})+ 9(1)-18)=-10\\y=-10$

Find the length of the missing side. Give your answer in the simplest radical form.

taurus [48]

Answer:

x = $2\sqrt{5}$

Step-by-step explanation:

Use Pythagorean theorem,

Hypotenuse² = base² + altitude²

x² = (√8)² + 4²

= 8 + 16

= 20

x = √20 = $\sqrt{2*2*5} = 2\sqrt{5}$

x = $2\sqrt{5}$

A parallelogram has a length of 6 centimeters and a width of 4.5 centimeters. This parallelogram is dilated by a scale factor of

Arada [10]

Scale factor is given by:
(length of larger figure)/(length of smaller figure)=(width of larger figure)/(width of the smaller figure)=3.4
The length of the larger figure will be given by:
length=(scale factor)*(length of smaller figure)
=3.4*6=20.4 cm
width of the larger figure will be given by:
width=(scale factor)*(width of smaller figure)
=3.4*4.5
=15.3 cm
Therefore the dimension of the new parallelogram will be 20.4 cm by 15.3 cm
