How to Write an Equation that Models a Situation?Using the information given, we can create an equation in slope-intercept form y = mx + b, where m would be the slope and b would be the y-intercept of the linear equation.
Let,
y = total costx = number of calendarm = cost per calendar = slope = 5b = initial value/y-intercept = 151. To create an equation that models the situation, substitute m = 5 and b = 15 into y = mx + b:
y = 5x + 15.
2. The variables and numbers in the equation are:
y = total cost
x = number of calendar
m = cost per calendar = slope = 5
b = initial value/y-intercept = 15
3. Substitute x = 200 into y = 5x + 15
y = 5(200) + 15
y = 1,015
Total cost = $1,015.
4. The equation in slope-intercept form is: y = 5x + 15
5. The slope (m) = 5
6. The y-intercept (b) = 15
To find the x-intercept, substitute y = 0 into y = 5x + 15
0 = 5x + 15
-5x = 15
x = 15/-5
x = -3
The x-intercept = -3.

Help am i correct? I need help please give explanation
====================================================
Reason:
Focus on the numerator for now. The [tex](11^8)^2[/tex] is the same as [tex]11^{16}[/tex] because we multiply the exponents. The general rule is [tex](a^b)^c = a^{bc}[/tex]
Alternatively we can think of it like this
[tex](11^8)^2 = (11^8)(11^8) = 11^{8+8} = 11^{16}[/tex]
So far we have [tex]\frac{(11^8)^2}{11^3} = \frac{11^{16}}{11^3}[/tex]
------------
The last step is to subtract exponents due to the rule [tex]\frac{a^b}{a^c} = a^{b-c}[/tex] and the order of subtraction is important.
Therefore, [tex]\frac{(11^8)^2}{11^3} = \frac{11^{16}}{11^3} = 11^{16-3} = 11^{13}[/tex]
Is 0.6294 terminating or repeating
Answer:
This is terminating. As a fraction it would be: [tex]\frac{6294}{10000}[/tex] not simplified
Step-by-step explanation:
If it was repeating you would see a repeat bar over part of the number. Or 3 .... showing that the number goes on.

How much 8% saline solution should Kent mix with 60 cubic centimeters (cc) of an 18% saline solution to produce an 11% saline solution?
cubic centimeters of an 8% saline solution is needed.
X
5
Based on the concentration of the saline solution and the cubic centimeters of the saline solution, the amount that should be mixed is 140 cubic centimeters
How to find out the cubic centimeters for mixing?Assuming that the quantity of the saline solution that Kent should mix is denoted by x, the formula would be:
0.08x + (0.18 x 60) = 0.11 (x + 60)
Solving gives:
0.08x + 10.8 = 0.11x + 6.6
10.8 - 6.6 = 0.11x - 0.08x
4.2 = 0.03x
x = 4.2 / 0.03
x = 140 cubic centimeters
In conclusion, 140 cubic centimeters of the saline solution is needed.

What is linear equation ?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."a manual computation on how 1 member recruits his members until week 5.

Answer:
(-3, -5)
Step-by-step explanation:
Adding the equations, we get 2y = -10, and thus y = -5.
Substituting this back into the first equation gives us that x = -3.

How many liters each of a 10 % acid solution and a 40 % acid solution must be used to produce 60 liters of a 35 % acid solution? (Round to two decimal places if
necessary.)
Hence , 10 liters of a 10% acid solution and 50 liters of a 40% acid solution must be used.
System of Equations: Setting up a system of equations containing the 2 unknown values, the substitution technique is also accustomed acquire associate degree equation with just one of the unknowns. The ensuing equation could then be resolved to search out the worth of the remaining unknown. From here, the second worth is also obtained by subbing the primary worth back to at least one of the equations.Let the amount of 10 % acid solution be " x " and the amount 40 % acid solution be " y " .
The total volume of the resulting solution is 60 L which can be given by
x + y = 60 .....(1)
The total acid in the resulting solution is 35 % acid solution which is given by 0.10 x + 0.40 y = 0.35(60) .....(2)
Multiplying by 100 in equation (2) , we get
10 x + 40 y = 2100 .....(3)
Putting x = 60 - y in equation (3) , we get
10 ( 60 - y ) + 40 y = 2100
600 - 10y + 40y = 2100
30y = 1500
y = 50
Putting y = 50 equation (1) , we get
x = 60 - 50 = 10

Michael and Lauren each have a coin collection.
The number of coins in Michael's collection can be represented by x.
The number of coins in Lauren's collection is 5 times the number in Michael's collection.
The total number of coins in both collections is 366.
What is x, the number of coins in Michael's collection?
If the number of coins in Lauren's collection is 5 times the number in Michael's collection and the total number of coins in both collection is 366, then the number of coins in Michael's collection is 61
The number of coins in Michael's collection = x
The number of coins in Lauren's collection is 5 times the number in Michael's collection
Then the number of coins in Lauren's collection = 5x
The total number of coins in both collection = 366
Combine the values and the equation will be
x+5x=366
Add like terms
6x= 366
x=[tex]\frac{366}{6}[/tex]
x=61
Hence, if the number of coins in Lauren's collection is 5 times the number in Michael's collection and the total number of coins in both collection is 366, then the number of coins in Michael's collection is 61
