Step-by-step explanation:
14x and 6y both have variables attached to them
the most basic form for a function like this is ax+by+c
the definition of constant is a fixed value. the reason your constant has to be a solo number, not attached to a variable, is that these variables change the number!! so, -5, the only number that won't change in the function, is the constant.

Carmen is an engineer making plans to run a rail line, represented by the transversal t, through a city.
Parallel lines v and w are crossed by transversal t. Clockwise from top left, the angles formed with line v are 155 degrees, blank, blank, blank; with line w are 1, 2, 3, 4.
Examine Carmen’s rail plans to identify the measure of ∠1. The streets represented by lines V and W are parallel.
What is the mAngle1?
25°
35°
145°
155°
Answer:
155
Step-by-step explanation:
The measure of <1 is 25.
What is Parallel line?The fundamental characteristics listed below make it simple to recognize parallel lines.
Straight lines that are always the same distance apart from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.Given:
The streets represented by lines V and W are parallel.
We need to determine the measure of ∠1.
As, Corresponding angles are those in the matching corners formed when a transversal line crosses two parallel lines.
Additionally, the size of the corresponding angles is consistently the same.
So, From the figure, the ∠1 and the other angle in the parallel line V with the measure of angle 155° are corresponding angles.
Thus, the measure of ∠1 is 155°

3. Write an equation in slope-intercept form of the line that passes
through the point (4, -1) and has a slope of 2.
A. y = 2x - 7
B. y = 2x - 9
C. y = 2x + 7
D. y = 2x + 9
Answer:
B. y = 2x - 9
Step-by-step explanation:
All of the answer choices has a slope of 2, but B is the only answer choice that has (4,-1) on its line.
You can tell by plugging the point into the equation and seeing if the result is true.
y = 2x - 9

Answer:
1815 pi cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the diameter =22
so the radius is d/2 = 22/2 =11
V = pi (11)^2 (15)
V = pi1815

The Last Equation
Step-by-step explanation:
[tex]2(x+3)=32[/tex] is the same thing as [tex]2x+6=32[/tex].
Why? Because if you apply the distributive property...
[tex]2(x+3)=32\\2 * x =2x\\2*3 = 6\\\boxed {2x+6=32}[/tex]
You get what was mentioned in the question!
So, 2(x+3)=32 should have the same solution as 2x + 6 =32.
Brainilest Appreciated.
Answer:
The bottom choice, 2(x + 3) = 32
Step-by-step explanation:
2x + 6 = 32
Subtract 6 from both sides of the equation
2x = 26
x = 13
Substitute the new value for x into all of the possible equations
1) 2x = 38, 2) x - 3 = 16 3) x + 6 = 16 4) 2(x - 3) = 16
13 * 2 = 38 13 - 3 = 16 13 + 6 = 16 2x - 6 = 16
26 = 38 10 = 16 19 = 16 13(2) - 6 = 16
False False False 26 - 6 = 16
20 = 16
False
5) 2(x + 3) = 32
2x + 6 = 32
2(13) + 6 = 32
26 + 6 = 32
32 = 32
True
The last answer choice, (the 5th one down) is correct

Solve for x. Show or explain your work. Then, verify that your solution is correct.
Answer:
see below
Step-by-step explanation:
-15 = 2x + 1
Subtract 1 from each side
-15-1 = 2x + 1-1
-16 = 2x
Divide each side by 2
-16/2 = 2x/2

-15 = -15
Answer:
-8
Step-by-step explanation:
subtract 2x to move it to the left side
-2x-15=1
add 15 to move it to the right side then add 1 to 15 since it would be 15 plus 1
-2x=16
divide by -2 to get x by its self
-2x=16/2x

Explain your work please
Answer:
6√2
Step-by-step explanation:
This is a right triangle. The legs of a right triangle are the sides that make up the right angle, and the hypotenuse is the side opposite to the right angle. To find x, we will use the Pythagorean Theorem. This states that a² + b² = c², where a and b are the legs and c is the hypotenuse. Since we know that the legs are both x and the hypotenuse is 12, we can plug these values into our equation to get x² + x² = 12².
2x²=144 → x² = 72 → x = √72, which simplifies to x = 6√2. Hope this made sense and helps!

4. compare 5 gal and 18 qt
6. compare 4.5 km and 5,000m
PLS HELP HURRY ASP BEST ANSWER. GETS BRAINLESST
Answer: >,<
Step-by-step explanation:
18 qt = 4.5 gallons which is not greater than 5 gallons
4.5km = 4,500 m is not greater than 5,000 m
Answer:
1st: 5 gal > 18 qt
2nd: 4.5 km < 5,000 m
Step-by-step explanation:
1 gallon is equal to 4 quarts
Going by this logic, 5 gallons should be 20 quarts. Since it says 18, 5 gallons is more than it. So the answer is '>'.
1 kilometer is the same as 1000 meters
4.5 kilometers * 1000 = 4,500 meters
5000 meters / 1000 = 5km
So the answer should be '<' since 5,000m is greater than 4.5km.

In quadrilateral BCED, we have BD = 11, BC = 9, and CE=2. Sides BD and CE are extended past B and C, respectively, to meet at point A. If AC = 28 and AB = 24, then what is DE?
Answer:
DE = 11.25 units
Step-by-step explanation:
The image of the quadilateral BCED and the extensions of BD and CE to move past B and C to meet at A is presented in the attached file to this answer.
Let the angle at A be θ
Let the length of DE be x
ABC forms a triangle which van allow θ to be obtained using cosine rule.
BC² = AB² + AC² - (2×AB×AC×cos θ)
BC = 9
AB = 24
AC = 28
9² = 24² + 28² - (2×24×28×cos θ)
-1279 = -1344 cos θ
Cos θ = (1279/1344) = 0.9516
θ = 17.89°
Note that ADE also forms a triangle and we can also use cosine rule to obtain the required side DE
DE² = AD² + AE² - (2×AD×AE×cos θ)
DE = ?
AD = AB + BD = 24 + 11 = 35
AE = AC + CE = 28 + 2 = 30
θ = 17.89°
DE² = 35² + 30² - (2×35×30×cos 17.89°)
DE² = 126.54
DE = √126.54 = 11.25
Hope this Helps!!!
The value of DE in the quadrilateral is 11.25 units.
How to solve the quadrilateral?From the information given, the cosine rule can be used. This will be:
BC² = AB² + AC² - (2 × AB ×AC × cos)
Therefore,
9² = 24² + 28² - (2 × 24 × 28 × cos)
cos = 17.89°
Therefore, the value of DE will be calculated thus:
DE² = 35² + 30² - (2 × 35 × 30 × cos 17.89)
DE = ✓126.54
DE = 11.25
In conclusion, the value of DE is 11.25 units.
