2 answers:

8 0

The percent of change would be -33.3% which would then equal a 33.3% decrease (when decimal is rounded)

what I did was turn 1/4 and 1/2 into decimals to make it easier to solve

The combined average weight of an okapi and a llama is 450450 kilograms. The average weight of 33 llamas is 190190 kilograms mor

Nataliya [291]

Answer:

Okapi 290 kg

Llama 160 kg

Step-by-step explanation:

Let weight of each llama be $l$

Let weight of each okapi be $o$

<em>Given, combined weight of 1 okapi and 1 llama is 450, we can write:</em>

<em>Also, average weight of 3 llama is 190 more than the average weight of 1 okapi, thus we can write:</em>

Now, substituting 2nd equation into 1st equation, we can solve for weight of 1 llama:

$l+o=450\\l+(3l-190)=450\\l+3l-190=450\\4l=450+190\\4l=640\\l=\frac{640}{4}=160$

Each llama weights 160 kg, now using this and plugging into 2nd equation, we get weight of 1 okapi to be:

$o=3l-190\\o=3(160)-190\\o=290$

Each okapi weigh 290 kg

Which equation represents a linear function that has a slope of 4/5<br> and a y-intercept of –6?

vredina [299]

Answer:

$\large\boxed{y=\dfrac{4}{5}x-6}$

Step-by-step explanation:

The slope-intercept form of equation of a linear function:

$y=mx+b$

m - slope

b - y-intercept

We have the slope m = 4/5 and the y-intercept b = -6. Substitute:

$y=\dfrac{4}{5}x-6$

PLEASE HELP ME SOLVE THIS FUNCTION!!!! 20 POINTS!!!!

const2013 [10]

The expression which represents the function required to be generated; (f +g)(x) as in the task content is; 13x -2.

<h3>What is the expression which represents the function required?</h3>

It follows from the function definitions in the task content that the functions given are;

f(x) = 4x +5

g(x) = 9x -7

Hence, the value of (f +g)(x) = f(x) + g(x) and ultimately;

= 4x +5 + 9x -7

= 13x -2
