The point-slope equation of the line for the given slope and coordinates is found as : y = -3x - 16.
Define the term point-slope equation?A line's equation written using a single point here on line and the line's slope is referred to as the point-slope form. The slope has been the rise with run, or the proportion of the change there in y values out over changes in the x values, and the point form is denoted as (x,y).For the stated question.
The slope of the line m = -3.
Coordinates = (5,-7)
The general point-slope equation is given as:
y - y1 = m (x - x1)
y - 5 = -3(x + 7)
y - 5 = -3x - 21
y = -3x - 16
Thus, the point-slope equation of line for the given slope and coordinates is found as : y = -3x - 16.

Under his cell phone plan, Liam pays a flat cost of $69.50 per month and $5 per gigabyte. He wants to keep his bill under $90 per month. Write and solve an inequality which can be used to determine x, the number of gigabytes Liam can use while staying within his budget.
Using a linear function, the inequality is given by: 69.5 + 5x < 90.
The solution is: x < 4.1.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, we have that:
The y-intercept is the flat cost of $69.50.The slope is the cost per gigabyte of $5.Hence the cost of using x gigabytes is:
C(x) = 69.5 + 5x.
The cost has to be under 90, hence the inequality is:
C(x) < 90
69.5 + 5x < 90.
Then the solution is:
5x < 90 - 69.5.
x < 20.5/5
x < 4.1.

At 2 hours, the traveler is 725 miles from home.At 3 hours, the distance is constant, at 875 miles.The total distance from home after 6 hours is 1,062.5 miles.How to determine the times and distances are represented by the function?From the function, we have the following piecewise function and the domains
D(t) = 300t + 125, 0 ≤ t < 2.5
D(t) = 875, 2.5 ≤ t ≤ 3.5
D(t) = 75t + 612.5, 3.5 < t ≤ 6
When t = 2, we use the domain 0 ≤ t < 2.5
So, we have
D(2) = 300 * 2 + 125
Evaluate the product
D(2) = 600 + 125
Evaluate the sum
D(2) = 725 --- this is true
When t = 3, we use the domain 2.5 ≤ t ≤ 3.5
So, we have
D(t) = 875
This gives
D(3) = 875 -- this is true
When t = 6, we use the domain 3.5 < t ≤ 6
So, we have
D(t) = 75t + 612.5
This gives
D(6) = 75* 6 + 612.5
Evaluate the product
D(6) = 450 + 612.5
Evaluate the sum
D(6) = 1062.5 --- this is true

The total mass of 4 identical pencil boxes and a notebook is 700 g. each pencil box has a mass of 140 g. what is mass of the notebook?
Answer:
140g
Step-by-step explanation:
One pencil box has a mass of 140g, to find out the weight of 4 pencil boxes we multiply 140 by 4: 140*4 = 560g
Let the mass of the notebook be x: 560+x = 700
560+x = 700
x = 140g

No
Step-by-step explanation:
Lets simplify both expressions:
We will start with Gloria's first expression:
[tex]1/4 (12x + 24) -9x[/tex]
Apply distributive property:
[tex](3x + 6) -9x[/tex]
Combine like terms, we are then left with:

Now lets simplify the second expression

Rearrange:

Now we can see that the two equations are not equal, as the first is 12 greater than the second. Another way we could have tested this was plugging in a value for x and then solving.

Find the roots if one of the roots is the product of the other two
Step-by-step explanation:
x³ - x² - 24x - 36
factors of -36 are 1, 2, 3, 4, 6, 9, 12, 18, 36 and negative equivalents.
1 - 1 - 24 - 36 != 0
8 - 4 - 48 - 36 != 0
27 - 9 - 72 - 36 != 0
64 - 16 - 96 - 36 != 0
216 - 36 - 144 - 36 = 0
So one factor is 6
x = 6
(x - 6) = 0
x²(x - 6) = x³ - 6x²
5x(x - 6) = 5x² - 30x
6(x - 6) = 6x - 36
x³ - 6x² + 5x² - 30x + 6x - 36
(x - 6)(x² + 5x + 6)
(x - 6)(x² + 3x + 2x + 6)
(x - 6)(x(x + 3) + 2(x + 3))
(x - 6)(x + 3)(x + 2)
x - 6 = 0
x = 6
x + 3 = 0
x = -3
x + 2 = 0
x = -2
x = -2, -3, 6.
One is the product of the other 2 as -2 x -3 = 6.

Point A is at (3, -8) and point B is at (7, 3). Point M is the midpoint of point A and point B.
The midpoint of point A and point B is (5, -2.5)
How to determine the midpoint?The coordinates are given as:
A = (3, -8)
B = (7, -3)
The midpoint is calculated as:
(x, y) = 0.5 * (x1 + x2, y1 + y2)
So, we have:
(x, y) = 0.5 * (3 + 7, -8 + 3)
This gives
(x, y) = 0.5 * (10, -5)
Evaluate
(x, y) = (5, -2.5)
Hence, the midpoint of point A and point B is (5, -2.5)
