Answer:
y = x - 8
Step-by-step explanation:
The equation of the straight line which is perpendicular to the straight line y = -x -3, will be y = x + c' ....... (1), where c' is a constant.
{This is because the product of the slopes of two mutually perpendicular straight line is -1}
Now, (3,-5) point satisfies equation (1).
Hence, -5 = 3 +c', ⇒c' = -8.
Therefore, the equation of the required straight line in slope-intercept form is y = x - 8 (Answer)
{Note: The slope-intercept form of a straight line is y = mx + c, where m is the slope of the line i.e. tanФ, and c is the length of y-axis intercept.}
The equation of a circle
defines a circle centred at (xc,yc) with radius r.
So with (xc,yc)=(0,3), and r=4
the equation becomes
Answer:
it will be 100 mpg
Step-by-step explanation:
because 20 times 2 gallons is 40 and 20 time 3 is 60 then 20 times 4 is 80 then 20 time 5 is 100 if you just remember your times tables for two you will get your answer all your doing is just add a 0 to two for 20
Answer:
22.4/33.6
Step-by-step explanation:
hope this helpsss
100/2+3 = 20
2*20= 40
3*20 = 60
