Step-by-step explanation:
we start first by finding the gradient of the line
change in y/change in x
7-(-1)/3-7=8/-4
=-2
then for perpendicular lines m1m2=-1
therefore to find the gradient of that line
-2m2=-1
therefore m2=2
so therefore
y-5/x-3=2
so y-5=2x-6
y-2x=-1
in the form y= mx +c
then y=2x-1
Answer:
The rate of change is $1.50
Step-by-step explanation:
To find this answer i divided $150 by 100 and got 1.5 which is $1.50
Answer:
Step-by-step explanation:
Average rate equals the negative of delta concentration of reactants
Answer:
Domain: x >0
Range : y < 0
Step-by-step explanation:
Answer:
r = 32
Step-by-step explanation:
R is the variable that we are trying to find.
24 = 3/4r
Since r is being multiplied by 3/4, we need to divide 3/4 on both sides to "undo" the multiplication.
24 / 3/4 = 3/4r / 3/4
32 = r
Therefore, r = 32.
To check, we can plug 32 into the equation.
24 = 3/4 x 32
3/4 x 32 = 24
