Answer:
Step-by-step explanation:
Given the coordinates D(-2, 3), E(5, 5), F(-4, 10), to find the measure of the sides, we will use the formula for calculating the distance between 2 points as shown:
D = √(y2-y1)²+(x2-x1)²
For DE;
D(-2, 3), E(5, 5),
DE = √(5-3)²+(5-(-2))²
DE = √2)²+7²
DE = √4+49
DE = √53
For DF;
D(-2, 3), F(-4, 10)
DF = √(10-3)²+(-4-(-2))²
DF = √7²+(-2)²
DF = √49+4
DF = √53
For EF;
E(5, 5) F(-4, 10)
EF = √(10-5)²+(-4-5)²
EF = √5²+(-9)²
EF = √25+81
EF = √106
Since two he sides DE and DF are equal, this shows that the triangle is an isosceles triangle. An isosceles triangle is a triangle that has two of its sides and angle equal
define the term perpendicular
Answer:
Perpendicular refers to that which has a right angle in relation to the intersection of two lines or planes. ... As seen in the Cartesian plane, what defines a line as perpendicular is its point of intersection with another line.

The value of y directly proportional to the value of x. If y= 8 when x= 12, what is the value of y when x= -15?
The value of y directly proportional to the value of x. If y= 3 when x= 24, what is the value of y when x= -8?
Answer:
The value of y should be -10
Step-by-step explanation:
If x and y are proportional, then 8/12=y/-15
The fractions just show the y values over the x values
Cross multiply to get 12y= -120
y= -10

Solve for the values of x:
(2x-1)(x+4) = 0
Step-by-step explanation:
x = -4, 1/2 is the value of x
The values of x that satisfy the equation (2x - 1)(x + 4) = 0 are
x = 1/2 and x = -4.
Here, we have,
To solve for the values of x in the equation (2x - 1)(x + 4) = 0, we can use the zero-product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be zero.
So, we set each factor equal to zero and solve for x:
2x - 1 = 0
Adding 1 to both sides:
2x = 1
Dividing both sides by 2:
x = 1/2
x + 4 = 0
Subtracting 4 from both sides:
x = -4
Therefore, the values of x that satisfy the equation (2x - 1)(x + 4) = 0 are x = 1/2 and x = -4.

What are the partial products of 364 x 257?
what is the inverse of f(x)? show the work
f(x)+3x+5
Answer:
[tex]f^-^1(x)=\frac{1}{3}x-\frac{5}{3}[/tex]
Step-by-step explanation:
To solve for the inverse, we need to switch the variables and solve for y.
Note that f(x) is the same as y or in other words, the output.
f(x) = 3x + 5
y = 3x + 5
~Switch variables
x = 3y + 5
~Subtract 5 to both sides
x - 5 = 3y
~Divide 3 to everything
1/3x - 5/3 = y
~Flip
y = 1/3x - 5/3

Answer:
x = 6°
y = 15°
Step-by-step explanation:
90 + 6y = 180 (linear pair, supplementary)
6y = 90 (180 - 90)
y = 15°
6y and 5x + 60 are corresponding angles. Corresponding angles are equal
Hence:
6y = 5x + 60
Sub y = 15° into equation
90 = 5x + 60
90 - 60 = 5x
5x = 30
x = 6°

Meghan has her own business. When she makes money, it is called income. When she spends money, it is called expenses. Choose the phrases below to explain how to use positive or negative integers to represent income and expenses. You would use positive integers to represent income because it is a Choose... amount. You would use negative integers to represent expenses because they are opposites of income.
Answer and explanation:
When you use positive interger to represent income, it shows that there has been an addition instead of a subtraction in money value to the business. In other words money is coming in instead of going out. Example when there is profit on goods sold say $10, it is indicated with a positive integer 10 to indicate addition in terms of operating income
When you use a negative value to represent expense, it indicates there has been a subtraction instead of an addition in money value. In other words money is going out of the business and not coming in. Example when there is a transportation expense to convey goods to the buyer, it is recorded as expenses subtracted from say revenue sales of the business. expenses are usually indicated in brackets in accounting to show negative value, although not a requirement since they are already named and recognized as expenses and subtracted regardless
