Answer:
y= -4x+7
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Let's find the gradient of the line first.
Using the above formula,
Susbt. m= -4 into the equation:
y= -4x +c
Subst. a coordinate to find c.
When x=3, y= -5,
-5= -4(3) +c
-5= -12 +c
c= 12 -5
c=7
Thus the equation of the line is y= -4x +7.
<u>Answer:</u>
The ratio of the complement of x to the supplement of x is 2:5. The value of x is 30
<u>Solution:</u>
It is given that x represents the measurement of an acute angle in degrees. It is also given that the ratio of the complement of x to the supplement of x is 2:5.
Since it is given that x is an acute angle it means that it has to be less than 90.
Complement of an angle = 90 - x
Supplement of an angle = 180 - x
In this case it is given that the ratio of the complement of x to the supplement of x is 2:5
So we can write the relation as follows:
Therefore the value of x is 30.
