NO LINK SPAM OR REPORT: Tell whether x and y show direct variation. Explain your reasoning. If so, find k.
x−y=0
Answer:
2. yes; the equation can be written as y = kx; k = 1
Step-by-step explanation:
x-y = 0
That means x and y have to be the same value.
If you multiply a number by 1, you get the same thing.
If you multiply x by one, you get y (the same value).

Question
A map of a farm is shown in a coordinate plane in which the coordinates are measured in yards. The map shows the barn at (-5, 4). A well is dug at (-5, y). What are two values of y such that the barn is 30 yards from the well?
Answer:
y-34 or y-30
Step-by-step explanation:
Use the distributive property & multiply the 2x + 3 inside the parenthesis using the 4 outside the parenthesis.
Then, multiply them to both sides, to get . (8x+12) = yDistribute by multiplying y with 8x + 12 using the distributive property.Your final result will be 8xy + 12y / 5Learn more about distributive property here: brainly.com/question/2807928

Write the Pythagorean theorem equation in an equivalent form with the a² isolated.
Answer:
[tex]a^{2}= -b^{2}+c^{2}[/tex]
Step-by-step explanation:
Rewrite the Pythagorean Theorem equation in terms of [tex]a^{2}[/tex].
[tex]a^{2}+b^{2}=c^{2}[/tex]
Subtract b squared from both sides.
[tex]a^{2}= -b^{2}+c^{2}[/tex]
Answer:
A^2=-B^2+H^2
Step-by-step explanation:
A^2+B^2=H^2
Isolate A^2. Subtract B^2 from both sides.
A^2=-B^2+H^2

Define a variable, set up an equation, then solve.
Max is already 224 miles into his road trip. If he is averaging 52 miles per hour and the trip is 640 miles total, how many more hours does he have left to drive?
x - hours left to drive
Answer:
8 hours.
Step-by-step explanation:
1. Subtract 640-224=416
2. Divide 416/52
3. 8 hours
8 hours.
Step-by-step explanation:
We have been given that Max is averaging 52 miles per hour and the trip is 640 miles total. Max is already 224 miles into his road trip.
Let us find the remaining distance of trip by subtracting the distance already covered from total distance.
Remaining Distance = 640 miles - 224 miles
Remaining Distance = 416 miles
We will use formula: Time = Distance/Speed to find the number of hours Max still have to drive.
Time = 416 miles/52 miles/hour
Time = 416 miles/52 × hour/miles
Time = 416/52 hour
Time = 8 hours
Therefore, Max have left 8 more hours to drive.

Answer:
2 7/15
Step-by-step explanation:
2 2/5 + 1/15
Turn them into improper fractions.
12/5+1/15
In order to add fractions, they need the same denominator.
12/5x3/3=36/15
36/15+1/15=37/15
=2 7/15

What is the solution to the equation?
Enter your answer as a decimal in the box.
Answer:
-4.6
Step-by-step explanation:
Given the equation [tex]x5 = -0.92[/tex] isolate [tex]x[/tex] by multiplying 5 in both sides of the equation.
[tex]5\cdot\frac{x}{5} = -0.92\cdot5 \\x = -4.6[/tex]

Please explain I am very confused!
Answer:
42°
Step-by-step explanation:
Altitude of an isosceles triangle divides it vertex in equal angles
so ∠ABD = ∠PBC = 48/2 = 24
In ΔABC sum of angles = 180 and ∠A = ∠C
48 + A + C = 180
2A = 180 - 48 = 132
A = 132/2 = 66 = ∠C
As PB = PC ---> ∠PBC = ∠PCB = 24
∠ACB = 66 = ∠PCD + ∠PCB
66 = ∠PCD + 24
∠PCD = 42
Explain the relationship between a strategy, such as number sense, and a written method , such as partial products or area models , for multiplying decimal number's.
Answer:
Hello
Step-by-step explanation:
You can take away the decimals
for example 0.33 x 0.7
do 33 x 7
which is 231
the 0.33 has 2 decimal spaces because there are 2 digits after the point
0.7 has 1 decimal place because there is 1 digit after the point.
so in total, there is 3 decimal
because you do 2 + 1
3
from the left, you count backwards and add the decimal point
the final answer should be 0.231
