-7/12 should be subtracted from the sum of ( 5/6 + -2/3 ) to get 3/4.
Linear equations in one variable
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
For example, 2x+3=8 is a linear equation having a single variable in it.
Let x should be subtracted from the sum of ( 5/6 + -2/3 ) to get 3/4
Therefore
[ 5/6 + (-2/3 ] - x = 3/4
⇒ ( 5/6 - 2/3) - x = 3/4
⇒ ( 5/6 - 4/6) - x = 3/4
⇒ 1/6 - x = 3/4
⇒ x = 1/6 - 3/4
⇒ x = 4/24 - 18/24
⇒ x = -14/24
⇒ x = -7/12

Translate the sentence into an inequality.
The product of y and 5 is greater than or equal to - 20.
The product of y and 5 is greater than or equal to - 20 is 5y ≥ -20
What is an inequality?Inequalities are created through the connection of two expressions. It should be noted that the expressions in an inequality aren't always equal. Inequalities implies that the expressions are not equal. They are denoted by the symbols ≥ < > ≤.
In this case, the product of y and 5 is greater than or equal to - 20 will be:
(5 × y) ≥ -20
5y ≥ -20
This is the inequality.

Put the following equation of a line into slope-intercept form, simplifying all
fractions.
8x-20y=40
The equation of a line into slope-intercept form is represented as:
y = mx + c
where m = slope of the line
c = y-intercept of the line
On simplifying 8x - 20y = 40, the equation will be:
⇒ 2 (4x - 10y) = 2 (20)
⇒ 4x - 10y = 20
⇒ 2x - 5y = 10
⇒ 2x - 10 = 5y
⇒ 5y = 2x + (-10)
⇒ y = 2x/5 + (-10/5)
⇒ y = 2x/5 + (-2)
The slope of this line = 2/5
y-intercept of the line = -2
What is the Slope of a Line?A line's steepness is based on its slope. The slope is m in the equation y = mx + b, which is the common equation for a line. Additionally, it is frequently referred to as "rise over run," which indicates how much the y-value changes as the x-value changes.When a line advances from left to right and has a positive slope, the line rises (slopes up). When a line moves from left to right and has a negative slope, it descends (goes down).A line's slope can be determined by selecting two points from the line's graph and then providing the line's graph as input.The simplest method for doing this is to choose 2 locations on the line with integer coordinates, then add up the changes in x and y.To learn more about the Slope of a Line, refer to:

DeShawn ran 40.7 miles less than Mark (m) last week. DeShawn ran 9.3 miles. How many miles did Mark run? Do not include spaces in your answers. 20 points!!!
The number of miles that Mark ran was 50 miles.
How do we get the number of miles that Mark ran?We can get the number of miles that Mark runs by first assigning him the figure x.
Since DeSahwn ran 40. 7 miles less than Mark, we can express this thus:
x - 40. 7 miles.
If the number of miles that DeShawn ran was 9.3 miles we can factor that into the equation as follows:
x - 40. 7 miles = 9.3 miles
x = 9.3 + 40.7
x = 50 miles.
Therefore, the total number of miles that Mark ran was 50 miles.

Write equation in point slope form.
Answer:
y = (4/5)x + 16
Point-slope form:
y - 12 = (4/5)(x + 5)
Step-by-step explanation:
slope = m; (-5, 12)
m = (4/5) (x₁, y₁)
y - y₁ = m(x - x₁)
y - 12 = (4/5)(x - (-5))
y - 12 = (4/5)(x + 5)

Giorgio used all the vegetables shown in the table above for his dinner.
a. How much money did his meal cost?
Considering the cost of 3 bell peppers are $2.05, 4 tomatoes are $1.09, 2 onions are $0.65 and 5 potatoes are $0.33, and Giorgio used all these vegetables for his dinner, then his meal costed a total amount of $4.45.
As per the question statement, no information about the vegetables Gorgio used for his dinner or their prices are provided in the question statement, and thus we are considering that, Gorgio used 3 bell peppers that costed $2.05, 4 tomatoes at $1.09, 2 onions at $0.65 and 5 potatoes at $0.33 in his dinner recipe.
We are required to calculate how much does Gorgio's dinner meal cost.
To solve this question, we simply have to add up the prices of the ingredients and we will obtain our desired answer.
That is, Gorgio's meal costed a total amount of $(2.05 + 1.09 + 0.65 + 0.33)
= $4.45

Step-by-step explanation:
The graphs obey the function equations but the intervals are marked incorrect in #s 2 and 4
One thing to keep in mind is that when you have a piecewise function valid on certain intervals, the circle shape denoting the beginning of the interval is very important
If it is a filled circle it denotes a ≤ (or ≥) inequality
If it is an unfilled (hollow) circle it denotes a < (or >) inequality
Looking at the second graph we see that
f(x) = -1 for -∞ < x < -1
Assuming the interval is correctly defined, that solid circle at x = -1, y = -1 should be a hollow circle not a filled circle
Similarly for f(x) = 3x² + 3, the interval is given as -1 ≤ x < ∞ but the starting circle for this interval is an unfilled circle, it should be a filled circle
A similar situation applies to the fourth choice and you should be able to figure that out yourself

A portion of a square and a portion of a circle were used to create this figure. The perimeter of the figure is 36.28 units.
Given that,
A portion of a square and a portion of a circle were used to create this figure.
We have to find the perimeter of the figure.
Three linear sides are measured in units of 4, 8, 8, 4.
Radius of the circular part = 4 units
Measure of a polygon's circumference equals the polygon's perimeter.
From the figure we can see,
Figure perimeter equals the sum of the lengths of the three straight lines and the circumference of the quarter circle.
Measure of linear sides = 4 + 8 + 8 + 4 = 24 units
Circumference of the quarter circle = 1/4(2πr)
=1/2×π×4
=2×π
=2×3.14

Perimeter of the figure is 30+6.28

1. Point slope form
2. y = -2x + 25
The formula for point slope form is:
y − y1 = m(x − x1), which is exactly what y-7=-2(x-9) is, as y1 is 7, m is -2 and x is 9.
To get this into slope intercept form, we have to solve for y/ isolate it.
y - 7 = -2 (x-9)
First, distribute the -2.
y - 7 = -2x + 18
Then add 7 on both sides to get rid of the -7.
