Step-by-step explanation:
The standard form of an equation of a line:
We have the equation in the point-slope form. Convert:
Answer:
x=0, y=-12
Step-by-step explanation:
you can use substitution to solve for x
-3(x-12)=2x+36
-3x+36=2x+36
subtract 36 from both sides and add 3x to both sides
0=5x
x=0
now plug in 0 as x for either equation
y=0-12
y=-12
to check your work plug in x and y into the other equation
-3(-12)=2(0)+36
36=36
The equation that models the total cost is y = 100 + 22.5m
Step-by-step explanation:
Fitness member ship cost = $100
Monthly fee = $25
Discount = 10% on monthly fee
To calculate new monthly fee after discount,
25 - (25*10%) --> 25 - 2.5 --> $22.5
Number of months = m
Fee in m months = 22.5*m = 22.5m
<u>Equation:</u>
(c) is constant which is the membership fee
(x) is the monthly fee $22.5
(m) is the number of months
(y) is the total cost
So,
y = mx + c
y = m(22.5) + 100
y = 100 + 22.5m
Therefore, the equation that models the total cost is y = 100 + 22.5m

So 52 words per 1 minute
364 words per x minute
52:1 as is 364:x so
divide 364 by 52 and get 7
she typed 7 minutes
so 40% means 40/100 or 4/10
so 364=4/10
divide 364 by 2
364/2=182=2/10
multiply 182 by 5 ( to make 2/10 into 10/10) and get 910=words total to type
BUT WE WANT TO FIND WORDS LEFT so
910-364=546
she has 546 words left to type
