Answer:
The equations should have been added up to equal 180 instead of being set to equal each other. The two are supplementary angles, which can be seen due the rule that a pair of interior angles on the same side of the transversal is supplementary. To fix this issue from the work that they did, they should subtract the 140 from 180, so the correct measure of DKH is actually 40 degrees.

Answer:-9
Step-by-step explanation:
If f(x) = -x + 6, find f(-3).
Find f
The value of function f when x is (-3) is 9.
To solve the value of function for the value of x as -3, we will simply keep the value of x in the equation.
Rewriting the equation
f(x) = -x + 6
Keep the values of x in the above equation
f(x) = - (-3) + 6
Adding the two negative signs, hence, the value will be 3.
f(x) = 3 + 6
Performing addition to find the value of f(x) when value of x is (-3)
f(x) = 9
Therefore, the value of f(x) is 9.

Step-by-step explanation:
first you will try to get x by its self.
so were it says -5x = 3 you wanna do
+5 +5 on both sides to cancel out 5 so that would be
X = 8 because -5 + 5 is 0 which in this case will be left with X

Which is a unit rate?
1 Cookie/ 1/3 bag
1 Cookie/ 9 bags
2/3 cookies
3 cookies/bag
Answer:
3 cookies/bag
Step-by-step explanation:
First of all, let's define a unit rate. A unit rate is a ratio of the amount of one measurement to one unit of another measurement term. Unit rates can be expressed as fractions.
Now, here is something easier for you to remember: the second unit always have to be something with the quantity of 1.
In this case, "3 cookies/bag" shows how there are three cookies per, or in each bag--which means 1 bag. The second unit, which is bag, has the quantity of one.

A coffee machine dispenses 8-ounce cups of coffee automatically. the amount of coffee may vary by 3%. what are the least and greatest number of ounces the coffee machine may dispense?
If a coffee machine dispenses 8-ounce cups of coffee automatically. and the amount of coffee may vary by 3% then the least and greatest number of ounces the coffee machine may dispense is 7.76 and 8.24 respectively.
The least and greatest number of ounces the coffee machine may dispense can be calculated by converting the percentage given.
As, 3% = 3 / 100
3% of 8 = 3 / 100 × 8 = 24 / 100 = 0.24
Now by adding and subtracting the calculated value to 8, the least and greatest number of ounces can be determined.
8 - 0.24 = 7.76
8 + 0.24 = 8.24
Hence, the least ounces the coffee machine may dispense is equal to 7.76 and the greatest number of ounces the coffee machine may dispense is calculated to be 8.24 ounces.

a certain corner of a room is selected as the origin of a rectangular coordinate system. if a fly is crawling on an adjacent wall at a point having coordinates (1.5, 1.3), where the units are meters, what is the distance of the fly from the corner of the room?
The distance formula to get the distance of the fly from the corner of the room in meters is 1.985 meter.
Distance formula -
The distance formula is given by the equation -
[tex]d=\sqrt{ (x2-x1)^{2} +(y2-y1)^{2} \\[/tex]
[tex]where , (x_1, x_2)[/tex] and [tex](y_1,y_2)[/tex] are two given points.
Apply the distance formula to get the distance of the fly from the corner of the room in meters.
Now,
[tex]x_1 ,y_1[/tex] are form the origin,
Given:
[tex](x_2,y_2) =(1.5,1.3)[/tex]
By using the equation ,
[tex]d=\sqrt{ (x2-x1)^{2} +(y2-y1)^{2} \\[/tex]
[tex]\\d = \sqrt[2]{(1.5^{2} -0^{2})+ (1.3^{2}-0^{2} ) }[/tex]
[tex]d=\sqrt{(2.25+1.69)\\\\d=\sqrt{\frac{225}{100} +\frac{169}{100} } \\d=\sqrt{\frac{394}{100} } \\d=\frac{\sqrt{394} }{10} \\\\[/tex]
Root value of 394,
[tex]\sqrt{394}[/tex] = 19.85
[tex]d= \frac{19.85}{10} \\\\d=1.985[/tex] metre.
Therefore, the distance formula to get the distance of the fly from the corner of the room in meters is 1.985

the segment.
-2
Mid point of the length segment PQ has endpoints P(-3, 4) and
Q(1, 7) is (1,11/2).
Mid point = {(-3+1)/2, (4+7)/2}
Mid point = (1,11/2)
The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the endpoints, and it is equally distant from both of them. It cuts the section in half.
A line is said to be a bisector when it divides another line into two identical segments. The line will be split at its midpoint by the bisector. A compass and straightedge can be used to determine the midpoint of a line segment. See creating a line segment's perpendicular bisector.

In ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°. Find the length of u, to the nearest 10th of an inch.
Answer:
5.7
Step-by-step explanation:
Delta math
In ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°. Hence, the length of u is 5.54 inches.
What is a cosine law?Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.
u² = s² + t² - 2(s)(t)·cos U
Given that the ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°.
We can find the length of u by using the Cosine rule
u² = s² + t² - 2(s)(t)·cos U
u² = 4.6² + 1.8² - 2(4.6)(1.8)·cos 118
u² = 19.78 + 3.24 - 16.56 x cos U
u² = 19.78 + 3.24 + 7.77
u² = 30.79
u = 5.54
Hence, the length of u is 5.54 inches.

What is an equation of the line that passes through the point (8,-4) and is parallel to the line x-4y=12?
The equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.
Two lines with slopes m₁ and m₂ are parallel when m₁ = m₂ and perpendicular when m₁*m₂ = -1.
In the question, we are asked for the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12.
The given line can be shown as:
x - 4y = 12,
or, - 4y = - x + 12,
or, y = x/4 - 12/4,
or, y = x/4 - 3.
Comparing it to the slope-intercept form of a line, y = mx + b, we get the slope, m = 1/4.
The line parallel to this will also have the slope, m = 1/4.
The required line passes through the point (8, -4).
Using the one-point formula, (y - y₁) = m(x - x₁), we can write the required equation as:
y - (-4) = (1/4)(x - 8),
or, y + 4 = x/4 - 2,
or, y = x/4 + 2,
or, x/4 - y = -2,
or, x - 4y = - 8.
Thus, the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.
