Answer:
x+y=4
Step-by-step explanation:
No solution means that the lines will never intersect. We know that the slope of line A is -1, and it's y intercept is 2. If you look at the last option for the answer choices, it's slope is also -1, but it's y intercept is at 4. These lines have the same slope, also known as parallel, so they will never intersect, thus giving no solution
Answer:
x + y=4

I REALLY Need help ASAP
Answer:
A
Step-by-step explanation:
In order to multiply a whole number by a fraction, you can write the whole number in fraction form. -12 can also be written as [tex]\frac{-12}{1}[/tex].
Now you can write out [tex]\frac{-12}{1}[/tex] × [tex]\frac{20}{21}[/tex]
Multiply the numerators by each other and the denominators by each other to create one fraction.
-12 × 20 = -240 and 1 × 21 = 21
[tex]\frac{-12}{1}[/tex] × [tex]\frac{20}{12}[/tex] = [tex]\frac{-240}{21}[/tex] and now you can simplify the fraction by finding the greatest common factor of the denominator and numerator. -240 and 21 have the greatest common factor of 3. Divide each side by 3 and get the fraction -80/7

Answer in table format, picture below
Answer:
x = -0.35
Step-by-step explanation:
tep 1 - Multiply 64 and 0.5x. The answer ends up being 32x
Step 2 - You need to get all of the variables on one side and the regular numbers on the other side. To do that, you need to subtract 2.5x from each side so you are left with the equation -10.5 = 29.5x
Step 3 - The final step is to isolate the variable. To do this, you divide each side by 29.5 meaning that x = -0.35
Given the following graph
Find the amplitude and vertical shift?
Please write down the parent function and the function creating the graph.
Answer:
The amplitude = 2b, and the verticle shift = 2, which means it has been shifted down 2 units.
Step-by-step explanation:
The highest point is when y = 0 and the lowest point is when y = -4. The vertical distance between the peak and valley is 4 units, which cuts in half to 2. This is the amplitude. It's the vertical distance from the center to either the peak or valley.

8) If 15 balls cost Rs 225 then the cost of 8 balls is
Answer:
The cost of 8 balls is Rs $ 120.
Step-by-step explanation:
Given that 15 balls cost Rs $ 225, to determine the cost of 8 balls it is necessary to perform the following mathematical calculation:
(225/15) x 8 = X
15 x 8 = X
120 = X
Thus, the cost of 8 balls is Rs $ 120.

Consider that polynomials are a family. Members of the family are monomials, binomials, and trinomials explain
Answer:
Monomials mean one
binomials mean two
trinomials mean three
Step-by-step explanation:
mono means one
bino means two
Trump means three
Answer:
monomial, binomial, and trinomial is a polynomial. They are special members of the family of polynomials and so they have special names. We use the words ‘monomial’, ‘binomial’, and ‘trinomial’ when referring to these special polynomials and just call all the rest ‘polynomials’.
polynomial—A monomial, or two or more monomials, combined by addition or subtraction
monomial—A polynomial with exactly one term
binomial— A polynomial with exactly two terms
trinomial—A polynomial with exactly three terms

If the length of each square represents one inch, what is the length from corner B to corner C?
A.
15 inches
B.
12 inches
C.
14 inches
D.
13 inches
===========================================================
Explanation:
There are three methods to solve this problem
--------------------------
Method #1
Let point D be at the location (0,6). So this point is on line BC such that it cuts BC into two pieces of BD and DC.
BD is 7 inches long since it spans from x = -7 to x = 0
DC is also 7 inches long because it spans from x = 0 to x = 7
We can treat everything on line BC as if it was a number line.
So overall, BC = BD+DC = 7+7 = 14 inches
--------------------------
Method #2
Because points B and C are on the same horizontal level, we can subtract the x coordinates of each point. We apply absolute value to ensure the result of subtraction is never negative.
|B-C| = |-7-7| = |-14| = 14
or
|C - B| = |7 - (-7)| = |7 + 7| = |14| = 14
The order of subtraction doesn't matter as long as you use absolute value.
----------------------------
Method #3
We can use the distance formula to compute the distance from B(-7,6) to C(7,6)
So we'll make (x1,y1) = (-7,6) and (x2,y2) = (7,6)
Then we have the following steps
[tex]d = \text{Distance from B to C}\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-7-7)^2 + (6-6)^2}\\\\d = \sqrt{(-14)^2 + (0)^2}\\\\d = \sqrt{196 + 0}\\\\d = \sqrt{196}\\\\d = 14\\\\[/tex]
The distance from B to C is 14 inches, which is the same as saying segment BC is 14 inches long.
The distance formula is overkill in my opinion, so method 1 or 2 might be the better option.

3(5x - 6) = 6(2x - 12)
Answer:
x = -18
Step-by-step explanation:
Distribute: 3*5x = 15x ; 3*-6 = -18 ; 6*2x = 12x ; 6*-12 = -72
15x - 18 = 12x - 72
Add 18 to both sides: 15x = 12x - 54
Subtract 12x from both sides: 3x = -54
Divide both sides by 3: x = -18
Answer:
x= 17.666666...
Step-by-step explanation:
3(5x - 6) = 6(2x - 12)
(3 times 5x , 3 times -6) (6 times 2x, 6 times - 12)
15x-18 = 12x -72 (multiply insides)
-12x -12x (remove 12x from right side)
3x-19 = -72 (product)
+19 = +19 (add 19 left side to remove it)
3x = 53 (product)
x = [tex]\frac{53}{3}[/tex] (divide)
x= 17.666666... (answer)
x = 17.67 (if simplify)

Write an explicit formula for An, the nth term of the sequence 6, 18, 54, ....
Answer:
[tex] a_{n} = (6){3}^{n - 1} [/tex]
Step-by-step explanation:
6, 18, 54
First, recognize that this is a geometric sequence. To find the common ratio, divide the f
second term by the first term.
18/6 = 3
Check this with the second and third term.
54/18 = 3
Your common ratio is 3.
An explicit formula for a geometric equation is:
[tex] a_{n} = a_{1} {r}^{n - 1} [/tex]
We know the first term is 6 and the common ratio is 3. Plug in these values.
[tex] a_{n} = (6) {3}^{n - 1} [/tex]
This is your formula.
Hope this helps!
