Answer:

The approx. length of a reptile that has a mass of 20.5 grams is 75

Step-by-step explanation:

y=0.3x-2

Okay so the value for y in the equation would be 20.5 so plug the value of y into the equation:

20.5 = 0.3x-2

And we are wanting to find the approximate length of a reptile that has a mass of 20.5 grams.

1. 20.5=0.3x-2

2. 20.5=\frac{3x}{10} -2

20.5=\frac{3x}{10} + \frac{10(-2)}{10}

I would give you the whole explanation, but to save time the answer is x=75

Hope this helped you

Please give 5 stars and a thank you if correct! Have a good day!

The length of a rectangular floor is 2 feet more than the width. The area of the floor is 168 square feet. Kim wants to use a ru
defon
The area of the rectangular is expressed in the formula A = l*w where l is the length and w is the width. from the first satement, l = 2  + w; then A = (2+w)*w = 2w + w^2. If A is equal to 168, then w should be equal to 12 feet and l is equal to 14 feet. Hence the width due to the border limits is 12- 2*2 equal to 8 feet

Find the inverse of the function f (x) = 0.25x + 12.
worty [1.4K]

Answer:

g(x)=4x-48

Step-by-step explanation:

f(x)=0.25x + 12

substitute

f(x) with y

y=0.25x + 12

then replace x with y and y with x

x=0.25y + 12

swap equation

0.25y + 12 = x

0.25y = x - 12

divide both sides by 0.25

Y=4x-48

Find n please help me i’m desperate
Rus_ich [418]

Answer:

Step-by-step explanation:

First thing we need to do is to reconcile that r to the negative power.  You do that by following the rules for exponents.  If

\frac{x^m}{x^n}  then the rule is to subtract the lower exponent from the upper:

x^{m-n}

Doing that with our base of r:

\frac{r^3}{r^{-4}}   is  r^{3-(-4)}  which is  r^7

So it looks like what we have now is:

p^3q^2(p^4q^nr^7)=p^7q^5r^7

NOW we will follow the rules for multiplying like bases with exponents.  The rule for that is if you have like bases and you are multiplying those like bases, you add the exponents.  So I'm going to kind of break up that problem and put the like bases together:

p^3p^4q^2q^nr^7=p^7q^5r^7

Working on the left side, p to the 3rd times p to the 4 gives you p to the 7th, which is what we have on the right.  The r to the 7 is also the same on the left and the right.  Working on the q's now, if we have q to the 2nd and we are looking for n, then

q^{2+n}=q^5  so 2 + n = 5 and n = 3
