Answer:
y=-9x-4
Step-by-step explanation:
Perpendicular lines meet the following condition:
m2*m1= -1 (a)
where m is the slope of a line
m1 is given through equation of line 1, y =1/9 x+2
m2 must be -9 -> from eq. (a)
The Line has the following equation: y=mx+b, where m=-9 and the b is the interception with y axis.
Evaluating the above equation in (-1,5) we have the following equation
5= -9*(-1)+b, we have b=-4
The line has the following equation
y=-9x-4
Slope intercept form
Answer:
Step-by-step explanation:
Find the unit rate for this painting:
3/5 of wall surface 3/5 15 9
------------------------------- = --------------- * --------- = -----------
(8/15) hour 8/15 15 8
Jane could actually paint the whole wall plus 1/8 more of it in one hour.
Answer:
(-♾, ♾)
Step-by-step explanation:
A quadratic can accept any real x value. So the domain is All Real Numbers. This in interval notation is
(-♾, ♾)
This is read as negative infinity to positive infinity
-2 / 5y = 4
Multiply both sides by 5y:
-2/ 5y * 5y = 4 * 5y
refine: -2 = 20 y
Switch sides:
20 y = - 2
Divide both sides by 20
20 y / 20 = - 2 / 20
y = -1/10
hope this helps!
Answer: 20 baskets
Step-by-step explanation:
5/10=2 2 baskets of strawberries can be picked by 1 person in an hour. Half of that because there is half the time is 1. Each person can pick 1 basket in half an hour.
