Using a linear function, it is found that Tamara will need to order a new bag after 46 days.
What is a linear function?A linear function is modeled according to the following rule:
y = mx + b
In which:
m is the slope, which is the rate of change of the function, that is, the change in y divided by the change in x.b is the y-intercept, which is the the value of y when the function crosses the x-axis(x = 0).The slope and the intercept in the context of this problem are given as follows:
Slope of -0.4, as she uses 0.4 pounds a day.Intercept of 20, as the bag initially has 20 pounds.Hence the weight of the bag after d days is given by:
W(d) = 20 - 0.4d.
He needs to order a new bag when W(d) = 1.6, hence:
1.6 = 20 - 0.4d.
0.4d = 18.4
d = 18.4/0.4
d = 46 days.
Hence she needs to order the new bag in 46 days.

Which equation is correctly rewritten to solve for x? -fx -g = h
To solve for x, the equation -fx -g = h is correctly rewritten as x = -h/f - g/f.
Which equation is correctly rewritten to solve for x?An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.
Given the equation in the question;
-fx - g = h
Solve for x.
To solve for x simply means to make x the subject of the formula or equation.
-fx - g = h
Add g to both side
-fx - g + g = h + g
Negative g and positive g cancels out.
-fx = h + g
Now, divide each term in the equation by the coefficient of x
-fx/-f = h/-f + g/-f
x = -h/f + (-g/f)
x = -h/f - g/f
Therefore, to solve for x, the equation -fx -g = h is correctly rewritten as x = -h/f - g/f.

We write 5.14*10^5 to convert from 5.14*10^5.
What is scientific notation?
Using scientific notation, one can express extremely big or extremely small values. When a number between 1 and 10 is multiplied by a power of 10, the result is represented in scientific notation. For instance, 650,000,000 can be represented as 6.5 108 in scientific notation.Scientific notation consists of a coefficient multiplied by 10 raised to an exponent . To convert to a real number, start with the base and multiply by 5 tens like this: 5.14 × 10 × 10 × 10 × 10 × 10 = 514000(here are only 4 zeros because you cancel one zero to remove decimal) so we write 5.14*10^5 to convert from 5.14*10^5.

The mass of 7m chain = 7 x 2.16 kg = 15.12 kg
It says that 7m of grade 70 tow chain which has a diameter of 3/8'' is required to tow a car.
So length of the chain = 7m
Now given that the weight of the chain = 2.16kg/m
That is weight of 1m of chain = 2.16 kg = mass of 1m of chain
Here, weight corresponds to the mass itself, since both has the same unit 'kilograms(kg)'.
So to find the mass of 7m chain, we need to multiply mass of 1m chain to the length of the chain.
Thus, the mass of 7m chain = 7 x 2.16 kg = 15.12 kg

Write an equation for a line that is perpendicular to the line given by x=9 and passes through the point (-6,-3)
Answer:
y = -3
Step-by-step explanation:
We are given an equation of the line, x=9.
And we want to write another equation of the line that is perpendicular to x=9 and passes through (-6, -3).
There are 3 ways to write the equation of the line:
Slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept. Standard form, which is ax+by=c, where a, b, and c are integer coefficients, but a and b cannot be 0, while a also cannot be negative.Point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1,y_1)[/tex] is a point.Any one of these forms would work, but let's use slope-intercept form, as it is the most common way to write the equation of the line.
Perpendicular lines have slopes that multiply to get -1. They are also considered negative and reciprocal. For example, 5 and -1/5 would be the slopes of perpendicular lines.
So, let's find the slope of x=9.
If a line is written like x=9, it means that when it is graphed, it will be a vertical line, and a vertical line has an undefined slope.
As you may know, [tex]\frac{1}{0}[/tex] is also considered to be undefined. This means that the slope of this vertical line can be written as [tex]\frac{1}{0}[/tex].
Now, let's get the reciprocal of this slope (put the value of the numerator on the denominator and vice versa), then add a minus sign after it.
[tex]\frac{1}{0}[/tex] => [tex]-\frac{0}{1}[/tex] => 0
The slope of the line we're writing is 0.
We can replace m in y=mx+b with 0.
y = 0x + b
Now we need to find b.
As the equation passes through the point (-6,-3), we can use its values to help solve for b.
Substitute -6 as x and -3 as y in the equation.
-3 = 0(-6) + b
Multiply.
-3 = b
Replace b with -3 in the equation.
y = 0x - 3
This can also be written as:
y = -3
what is a possible absolute value inequality to represent -1≤x≤5?

What is Absolute Value?
The absolute value (or modulus) l x l of a real number x is the non - negative value of x without regard to its sign. For example, the absolute value of 5 is 5 , and the absolute value of -5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.
Now, the question is:
what is a possible absolute value inequality to represent -1≤x≤5
The representation of inequality -1≤x≤5 of absolute value will be :
-3 ≤ lx - 2l ≤ 3
Now, add 2 to each segment of the system of inequalities to solve for x while keeping the equation balanced:

x-15 = 7
+15 +15
x = 22
180-51 = 129
y+16 = 129
-16 -16
y = 113
Answer:
x = 22
y = 113
Step-by-step explanation:
The angles marked as (2x+7) and (3x-15) are vertical angles, and therefore are equal to each other.
2x + 7 = 3x - 15 simplifying:
7 = x - 15
22 = x
Angles marked as (3x-15) and (y+16) form a linear pair and are therefore supplimetery. Now that we know the value of x, we can set up the following equation.
3(22) - 15 + y + 16 = 180 simplifying:
66 - 15 + y + 16 = 180
66 + y + 16 = 195
y = 113

All the given options are correct
How to determine which of the equation is true?The variation expression is given as
(2x + 3y) ∝ (x + 5y)
Rewrite as an equation
So, we have
(2x + 3y) = k(x + 5y)
Remove the brackets
So, we have
2x + 3y = kx + 5ky
Collect the like terms
So, we have
kx - 2x = 3y - 5ky
This gives
x(k - 2) = y(3 - 5k)
Divide by both sides by y(k - 2)
x/y = (5k - 3)/(2 - k) --- option (a)
Multiply both sides by y
x = y(5k - 3)/(2 - k) --- option (b)
