If
x+y=-4
y-3x=16 or we cn write as
x+y=-4
-3x+y=16
i multiply the first equation by 3
3x+3y=-12
-3x+ y=16
4y=4
y=1
x+1=-4
x=-5

If a rug was 5 times as long as this record sheet. The length of this record sheet in centimeters is 100x centimeter
<u>Solution:
</u>
Given that a rug was 5 times than the record sheet.
Let assume the length of the record sheet = x units
Then from given information,
Length of the rug = 5x units
Conversion of measure of record sheet in centimeter completely depends upon in which unit the length is given.
Suppose the given length is in meters, than need to multiply the given length by 100 to get the length in centimeter that is
x meter =
= 100x cm
Conversion factor will change accordingly to the unit of given length which needs to be convert into centimeter.
Answer: (1.5, 0)
Step-by-step explanation:
Given : The shape of his satellite can be modeled by
where x and y are modeled in inches.
Now,the given equation
is a equation of parabola.
Here, coefficient of x is positive, hence the parabola opens rightwards.
On comparing this equation with standard equation
, we get

In standard equation, coordinates of focus=(m,0)
Thus for given equation coordinates of focus=(1.5,0)
