Answer:

Step-by-step explanation:

$x=\frac{mx2+nx1}{m+n}\\let~coordinates ~of~K~be~(x,y)\\12=\frac{3x+4*6}{3+4}\\12*7=3x+24\\3x=84-24\\3x=60\\x=60/3=20\\18=\frac{3y+4*9}{3+4}\\18*7=3y+36\\3y=126-36\\3y=90\\y=90/3=30\\so~K~is~(20,30)$

A line contains the points (4,5) and (3, -9). Write the equation of the line using point-slope form.

neonofarm [45]

Answer:

Step-by-step explanation:

original formula is: y - y1 = m (x - x1) ordinates= (x1, y1)

insert the a corresponding x and y coordinate:

y + 3 = -2 (x + 9)

Don't forget to change the signs depending on whether their positive or negative:

(3, -9) since 3 is positive but there is a minus in the formula it would be -3

since -9 is negative and in the equation there's a minus sign you would change it to positive. (negative times a negative equals a positive)

ASAP PLEASE HELP An ostrich egg has a mass of 1.2 kg to the nearest tenth of a kilogram. Find the minimum and maximum possible m

katen-ka-za [31]

The maximum possible measurement is 1.25 Kg and the minimum possible measurement is 1.15 kg

<u>Solution:</u>

Given mass of an ostrich egg is 1.2 Kg

We have to find the minimum and maximum possible measurements to the nearest tenth of a kilogram

The greatest possible error in measurement nearest tenth of a kilogram, is a half a tenth of a kilogram which is:-

$\frac{1}{2} \times \frac{1}{10}=\frac{1}{20}$

Now, the maximum value will be equal to calculated amount plus the error in measurement of value .i.e.

$\text { Maximum value }=1.2+\frac{1}{20}=1.2+0.05=1.25$

Now, the minimum value will be equal to calculated amount minus the error in measurement of value .i.e.

$\text { Minimum value }=1.2-\frac{1}{20}=1.2-0.05=1.15$

Hence, maximum possible measurement is 1.25 Kg

And the minimum possible measurement is 1.15 kg
