Answer:
Step-by-step explanation:
Logarithms are only able to make an equation linear if it is an exponential function. For example,
can be made linear by taking the natural logarithm of each side, causing it to become
. After some simplifying, you are left with
. You are then able to plot ln(y) vs. x to get a linear fit.
Step-by-step explanation:
2y+3=5x-18
swap both sides
5x-18=2y+3
add 18 to both sides
5x-18+18=2y+3+18
5x=2y+21
divide both sides by
5x/5=2y+21/5
X=2y+21/5
Answer:
0.12
Step-by-step explanation:
If you divide 2.40 by 20 you get 0.12
Answer:
Mark picked 35 cherries.
Step-by-step explanation:
Let sherry's cherry and mark's cherry be x and y respectively,
x + y = 75
x = 75 - y.....eqn ii
y - 15 = x/2...eqn ii
substituting eqn ii in eqn i,
y - 15 = x/2
or, y - 15 = (75 - y)/2
or, 2y - 30 = 75 - y
or, 2y + y = 75 + 30
or, 3y = 105
so, y = 35
