29-4 = 25
29+4 = 33
So, from 25 to 33 minutes.
y=2
Step-by-step explanation:
Make an equation of straight line by using the formula :y= mx+c
put the x-value of point (2,4) which is 2 and the gradient,m which is 2 into the straight line equation:
y=2x +c
So you need to find the y-intercept to complete the equation, therefore:
when y=0,
0=2(2)+c
c=-4
next the question ask to find the y-coordinate when x =3, therefore you just need to replace x in the equation with 3:
y=2(3)-4
y=4
we know that
Using the original score as the basis
If Misha increased her test score from 
% to 
%
then
the increase variation is equal to
%-%=
%
to find the approximate percent increase of Misha's test score we apply a rule of three
if %--------------> represents 
%
%----------------->x
%
therefore
the answer is
the approximate percent increase of Misha's test score is 
%
Answer:
x = -6
Step-by-step explanation:
-5x = 30
Divide each side by -5
-5x/-5 = 30/-5
x = -6
Answer:
Step-by-step explanation:
y intercept is 2
x intercept is 6.
