The linear equation that best models the situation is: y = 15x + 125.
How to Write a Linear Equation that Models a Situation?To write a linear equation, you need to determine the value of the unit rate or slope (m), and the value of the y-intercept or starting value (b). The linear equation in slope-intercept form that models the relationship between two variables x and y is expressed as, y = mx + b.
From the information given, we have:
The one-time membership fee is the starting value or y-intercept (b) = $125The cost per month to be a member is the unit rate or slope (m) = $15Let y represent total cost
let x represents number of months.
To write the linear equation that models this situation, substitute m = 15 and b = 125 into y = mx + b:
y = 15x + 125.

you are driving on a road that has a 8% uphill grade. this means that the slope of the road is 8/100. approximate the amount of vertical change in your position when you drive 200 feet.
the amount of vertical change in your position when you drive 200 feet is 16 feet
you are driving on a road that has a 8% uphill grade.
this means that the slope of the road is 8/100.
approximate the amount of vertical change in your position when you drive 200 feet
Therefore our proportion is: (where x is the "vertical" rise)
Slope is defined as rise so
8/100 = x/200
(8*200)/100 = x
16 feet = x
Hence , the amount of vertical change in your position when you drive 200 feet is 16 feet

The equation given 5x + 2y = 10 given, represents the slope considering the form Ax + By = C: by slope = - A/B = -5/2
How to find the slope of the lineAx + By = C
rewriting in standard form which is y = mx + c, where m is the slope, is done as follows
By = -Ax + C
y = ( - Ax + C ) / B
y = - Ax/B + C/B
comparing with standard form the slope, m is - A/B

Points X(6,4) and Y(-4,-6) are the endpoints of XY. What are the coordinates of point Z on XY such that XZ is 4/5 the length of XY
Answer:
(-2, -4)
Step-by-step explanation:
Z_x = (Y_x - X_x) * (4/5) = (-4 - 6) * (4/5) = -8
Z_y = (Y_y - X_y) * (4/5) = (-6 - 4) * (4/5) = -8
-8 + 6 = -2
-8 + 4 = -4
There is a proportional relationship between the amount of dark chocolate (in ounces), x, and the amount of almonds (in ounces), y, in each package of Sweet and Salty trail mix.
x (ounces of dark chocolate) 2 y (ounces of almonds) 8
Answer:
y = 4x
Step-by-step explanation:
You want an equation that represents the proportional relationship between ounces of chocolate (x) and ounces of almonds (y) when we know (x, y) = (2, 8).
Proportional relationA proportional relation can be written using the equation ...
y = kx
where k is a constant.
The value of k can be found if a pair of values is known for x and y.
k = y/x . . . divide by x
k = 8/2 = 4 . . . . use (x, y) = (2, 8) from the table.
The equation for the relationship is ...
y = 4x
The proportional relationship that accounts between the amount of dark chocolate and the amount of almonds is y = 4x.
What is ratio and proportion?
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. An equation known as proportion shows that the two ratios presented are equal to one another. A ratio is the comparative or condensed form of two quantities of the same type. We may determine how many times one quantity is equal to another using this relationship. The ratio can be defined as the number that can be used to represent one quantity as a percentage of another.
Given, for 2 ounces of dark chocolate(x), 8 ounces of almonds(y) are put in.
Taking the ratio as y to x, we have:
y/x = 8/2 ⇒ y/x = 4 ⇒ y = 4x
Thus, the proportional relationship that accounts between the amount of dark chocolate and the amount of almonds in each package of Sweet and Salty trail mix is y = 4x.

What are mathematics operations?
An operation is a function in mathematics that converts zero or more input values (also known as "operands" or "arguments") to a well-defined output value.The operation's arity is determined by the number of operands.Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the most commonly studied operations.A zero-arity operation, also known as a nullary operation, is a constant.The mixed product is an example of an arity 3 operation, also known as a ternary operation.Amy has 4 pounds of ground beef to make meatballs and he uses 3/8 pound per meatball to make 9 meatballs
We have to subtract 3/8 from 4
= 4 - 3/8
= 29/8
There are 29/8 pounds of ground beef left
Therefore the number of 1/8 pound meatball that can be produced from 29/8 pounds of ground beef can be calculated as follows;

Answer:

Step-by-step explanation:
f(x) = 3x³ - 4x + 6 and g(x) = x³ + 3x² + x - 3
A. (f+g)x = 3x³ - 4x + 6 + x³ + 3x² + x - 3 = 4x³ + 3x² - 3x + 3.

An Irrational Number is a real number that cannot be written as a simple fraction: 1.5 is rational, but π is irrational. The root values will also be irrational.
The number -3 is a rational number. We can write -3 in the form of p/q, i.e -3/1 where p is -3 and q is 1.
All rational numbers are obtained by dividing one integer by another.
Since it is possible to obtain -3 by dividing the integer
i.e -3 by 1, as in -3/1,

Step-by-step explanation:
-4/5+-1/3+1 2/5+7/3
Convert all to fractions having the least common denominator. The mixed denominators of 3 and 5 could be converted to denominators of 15, thereby allowing them to be numerically combined.
-4/5+-1/3+1 2/5+7/3
(-4/5)(3/3) = -12/15
(-1/3)(5/5) = -5/15
(+1 2/5) = (5/5 + 2/5) = (7/5)(3/3) = 21/15
(7/3)(5/5) = 35/15
Since we have a common denominator (15) we can now sum the individual fractions by adding their numerators:
-12 -5 + 21 + 35 = 39
Now add back the denominator
The result is 39/15

Write and solve an inequality which can be used to determine xx, the number of 40-kilogram crates that can be loaded into the shipping container.
HURRY !
We can load less than or equal to 285 number of 40 kg crates in the shipping container.
The inequality is like 13100 + 40x ≤ 24500
Given,
The weight of crates transported by a shipping container = 40 kg
The greatest weight that can be loaded into the container = 24500 kg
The weight of already loaded shipments in the container = 13100 kg
We have to find and solve an inequality that determines the number of 40 kg crates that can be loaded into the shipping container:
Lets take x as the number of 40 kg crates.
Therefore, weight of container = 40x
The weight should be less than or equal to the maximum weight that can be loaded into the container:
That is,
13100 + 40x ≤ 24500
Now, solve the inequality:
40x ≤ 24500 - 13100
40x ≤ 11400
x ≤ 11400/40
x ≤ 285

What is Rounding?
To estimate a certain number in a context, rounding is a process. Look at the next digit in the correct position to determine how to round a number; if it is less than 5, round down, and if it is 5 or more, round up. The term "rounding decimals" describes the accurate rounding of decimal figures.
How to round a figure
It rounds to the most important figure in the number. To round to a significant figure: look at the first non-zero digit if rounding to one significant figure. look at the digit after the first non-zero digit if rounding to two significant figures.
To understand this term lets take and example:
24982 correct to 1 significant figure
If we round up, then the answer is
30,000
but if we were to round down, the answer would be
20,000;
If we want to determine which one is correct, we have to look at the second digit of the original number, which is
4
Since the second digit is less than 5
we can round down, so the answer would have to be
20,000
Hence, 24982 round to 1 significant figure is 20,000
