9. A full-grown giraffe is about 6 times
1 answer:
<h3>The mass of full grown giraffe is 372.42 kg and mass of full grown lion is 62.07 kg and mass of full grown cheetah is 15.51 kg</h3>
<em><u>Solution:</u></em>
Let "a" be the mass of full grown giraffe
Let "b" be the mass of full grown lion
Let "c" be the mass of full grown cheetah
<em><u>A full-grown giraffe is about 6 times heavier than a full-grown lion</u></em>
a = 6b ------- eqn 1
<em><u>A full-grown cheetah is about one-quarter as heavy as a full-grown lion</u></em>
<em><u>Together, they are about 450 kg</u></em>
Therefore,
a + b + c = 450
<em><u>Substitute eqn 1 and eqn 2 in above</u></em>
<em><u>Substitute b = 62.07 in eqn 1</u></em>
<em><u>Substitute b = 62.07 in eqn 2</u></em>
Thus, mass of full grown giraffe is 372.42 kg and mass of full grown lion is 62.07 kg and mass of full grown cheetah is 15.51 kg

Answer: y - 1 = –(x –7)
or y –5 = –1(x –3)
The attachment shows the graph of these equations (identical)
Step-by-step explanation:
The basic form for a point-slope equation is
y - b = m(x - a)
a is the x-value from the given coordinate, b is the y-value form the given coordinate, m is the slope. x and y are the variables in the function.
To find the slope, m, use the given coordinates. Get the difference in the y-values and divide by the difference in the x-values. This is "rise over run."
Subtract the first coordinate from the second coordinate.
Given coordinate points: (3,5) and (7,1) substitute values:
m= 1 –5 / 7 –3 becomes m= –4/4 so the slope, m = –4/4
That is –1 The "1" is "understood," so only the negative sign represents the slope in the equation
To write the equation: Take the basic form, substitute b and a values from either given coordinate. And use the value of m we just calculated.
y - b = m(x - a) Using the second coordinate: (7,1)
y - 1 = –(x –7)
or using the first coordinate:
y –5 = –(x –3)
