Answer:

x>-1

Step-by-step explanation:

On the number line you can see that x is greater than -1

By the way the dark blue line represents what x equals :)

Are the ratios 25/45 and 15/27 proportional? Explain.

liberstina [14]

Write them out as a fraction then reduce them. If theyre the same then its proportional.

25/45 can be cancelled down to 5/9

15/27 can be cancelled down to 3/9

So no theyre not.

Which value is equivalent to: 1 1/2 divided by 4 1/2 x 1 1/3

Nostrana [21]

Answer:

The answer is 4/9

Step-by-step explanation:

Hi. Here's the work.

First turn everything into an improper fraction.

$1 \frac{1}{2}$ ÷ $4 \frac{1}{2} * 1 \frac{1}{3}$ = $\frac{3}{2}$ ÷ $\frac{9}{2} * \frac{4}{3}$

To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.

$\frac{3}{2}$ ÷ $\frac{9}{2} * \frac{4}{3}$ = $\frac{3}{2} *\frac{2}{9} *\frac{4}{3}$

Now we just multiply the fractions!

$\frac{3 * 2 * 4}{2 * 9 * 3}$ = $\frac{4}{9}$

The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)

What is a equation of the line that passes through the point (−5,7) and is parallel to the line x+5y=10

dsp73

Answer:

$\displaystyle y = -\frac{1}{5} x +6$

Step-by-step explanation:

<u>Equation of a LIne</u>

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

We are required to find the equation of a line that passes through the point (-5,7) and is parallel to the line x+5y=10.

This information provides us the values of h=-5 and k=7. We now need to determine the value of the slope.

Two parallel lines have equal values for the slopes. The equation of the line

x + 5y = 10

Can be rearranged in such a way we can find its slope. Let's solve it for y:

5y = -x + 10

$y = -\frac{1}{5}+2$

The slope of this line is -1/5 and that is the same value of the slope of our line, thus its equation is:

$\displaystyle y - 7 = -\frac{1}{5} ( x + 5 )$

Adding 7:

$\displaystyle y = -\frac{1}{5} ( x + 5 )+7$

Operating:

$\displaystyle y = -\frac{1}{5} x + -\frac{1}{5}*5 +7$

$\displaystyle y = -\frac{1}{5} x -1+7$

$\boxed{\displaystyle y = -\frac{1}{5} x +6}$
