Answer:

The last one is incorrect

Step-by-step explanation:

-4c^2 - 2c^2 = -6c^2

9c - c = 8c

9c - c is equal to 8c so that means the polynomial is wrong since they put 10c instead of 8c.

The distance between two stars is 9.0 x 10 to the power of -3 light years. A light year is equal to

sergey [27]

Answer:

The distance between the two stars in miles is 5.292 * 10^10 miles

Step-by-step explanation:

Here, we want to make a conversion from light year to miles

To make this conversion, we simply are going to multiply the light year by the miles

Mathematically, we have this as;

9 * 10^-3 * 5.88 * 10^12

= 52.92 * 10^9

= 5.292 * 10^10 miles

Alika [10]

Answer:

2 additional premium channels

Step-by-step explanation:

Using the given function, we substitute c(x) = 114 and solve for x:

114 =90 + 12x

Subtract 90 from both sides:

24=12x

Divide both sides by 12:

2=x

So you have ordered 2 additional premium channels.

Are the ratios 84/105 and 128/160 proportional? Give two different reasons to support your answer.

Karolina [17]

We have been given two ratios and we are supposed to compare our ratios whether they are proportional or not.

1. We will reduce our fractions to compare our ratios. Let us simplify each of our given fractions.

$\frac{84}{105}$

Let us divide numerator and denominator with greatest common factor. We can see that 21 is GCF of our ratio.

$\frac{4}{5}$

Now we will simplify our second ratio.

$\frac{128}{160}$

GCF of our fraction is 32. Upon dividing our fraction by 32 we will get,

$\frac{4}{5}$

We can see that our both ratios are similar.

2. Now we will find decimal values of our fractions.

$\frac{84}{105}=0.8$

$\frac{128}{160}=0.8$

We can see that $0.8=0.8$ .

Therefore, we can say that our ratios are proportional.
