The system of equations has one solution because the lines will eventually intersect.
O The system of equations has one solution because the lines will never intersect.
The system of equations does not have one solution because the lines will eventually intersect.
The name rintinnn dannnathavannenlistinn hann the linell RAUA internant
Answer:
The two lines are coincident (essentially the same line) so every point on the line is a solution. Normally you would say they have infinitely many solutions.
An example of this would be:
y = 2x + 3
2y = 4x + 6
The statement that matches this situation would be D.
Answer:
D. The system of equations does not have only one solution (it has infinitely many) because the lines do not intersect at *only* one point.

Which are equivalent expressions?
Check all that are true.
A) a + b + c = 3abc
B) 4x + 8y = 2(2x + 4y)
C) 4x + 8y = 4(x + 2y)
D) 4x + 8y + 12z = 4(x + 2y + 3z)
E) 5x + 10y = 5(x + 2y)
Answer:
B) 4x + 8y = 2(2x + 4y)
C) 4x + 8y = 4(x + 2y)
D) 4x + 8y + 12z = 4(x + 2y + 3z)
E) 5x + 10y = 5(x + 2y)
Step-by-step explanation:
We would assume a value for the variables a, b, c, x, y and z.
Let x, a = 1
Let y, b = 2
Let z, c = 3
A) a + b + c = 3abc
When a = 1, b = 2 and c = 3
Substituting into the above equation, we have;
1 + 2 + 3 = 3(1*2*3)
6 ≠ 3(6)
6 ≠ 18 (not equivalent)
B) 4x + 8y = 2(2x + 4y)
When x = 1 and y = 2
Substituting into the above equation, we have;
4(1) + 8(2) = 2(2*1 + 4*2)
4 + 16 = 2(2 + 8)
20 = 2(10)
20 = 20 (equivalent expression)
C) 4x + 8y = 4(x + 2y)
When x = 1 and y = 2
Substituting into the above equation, we have;
4(1) + 8(2) = 4(1 + 2*2)
4 + 16 = 4(1 + 4)
20 = 4(5)
20 = 20 (equivalent expression).
D) 4x + 8y + 12z = 4(x + 2y + 3z)
When x = 1, y = 2 and z = 3
Substituting into the above equation, we have;
4(1) + 8(2) + 12(3) = 4(1 + 2*2 + 3*3)
4 + 16 + 36 = 4(1 + 4 + 9)
56 = 4(14)
56 = 56 (equivalent expression).
E) 5x + 10y = 5(x + 2y)
When x = 1 and y = 2
Substituting into the above equation, we have;
5(1) + 10(2) = 5(1 + 2*2)
5 + 20 = 5(1 + 4)
25 = 5(5)
25 = 25 (equivalent expression).

What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Josie buys a scoop of dried cranberries and a scoop of dried bananas to make trail mix.
The dried cranberries weigh 8.5 ounces and cost $0.30 per ounce
The dried bananas weigh 10.5 ounces and cost $0.20 per ounce.
We need to find how much does Josie spend on the dried fruit in all
The total cost for cranberries weigh is 8.5×0.30
$2.55
The total cost for dried bananas weigh is 10.5×0.20
$2.1
The total Josie spend on the dried fruit in all is $2.55+$2.1

500 Bhadgaule caps bought for Rs. 200000 in Nepali market are sold in Britain after paying
5% export tax then 150% profit was made. Find the selling price of each Cap in Pound Sterling.
[£ 1 = Rs. 155.63]
Answer:
Selling price of each cap = £6.75 (Approx.)
Step-by-step explanation:
Given:
Number of caps = 500
Cost of caps = Rs. 200,000
Export tax = 5%
Profit = 150%
£ 1 = Rs. 155.63
Find:
Selling price of each cap
Computation:
Cost of 1 cap = 200,000 / 500
Cost of 1 cap = Rs 400
After Add export tax = 400 + 400(5%)
After Add export tax = Rs 420
After profit = 420 + 420(150%)
After profit = Rs 1050
Selling price of each cap = 1,050 / 155.63
Selling price of each cap = £6.75 (Approx.)

x = 120/29
Step-by-step explanation:
-1/6(x + 18) + 1/5(x + 5) = x - 6
-1/6x - 3 + 1/5x + 1 = x - 6
-1/6x + 1/5x + 1 - 3 = x - 6
-1/6x + 1/5x - 2 = x - 6
-5/30 + 6/30x = x - 6 + 2
1/30x = x - 4
1/30x - x = -4
-29/30x = -4
-29/30x • 30/29 = -4 • 30/29
-x = -4/1 • 30/29
-x = -120/29
-x/-1 = 120/29/-1

If $120.99 is charged for 654 units of electricity
used, find the cost of one unit of electricity,
plz help me solving this question step by step this is important for me
Answer:
The cost of one unit of electricity is $0.185
Step-by-step explanation:
Amount charged = $120.99
Units of electricity used = 654
The cost of a unit of electricity can be determined by dividing the amount charged by the number of units used.
So that,
cost of one unit of electricity = [tex]\frac{120.99}{654}[/tex]
= 0.185
cost of one unit of electricity = $0.185
This implies that the cost of electricity used is charged at $0.185 per unit.
Thus for 654 units of electricity used, the cost would be;
654 x $0.185 = $120.99

Answer:
53.33% probability he calls a person from school.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
What is P(call a person from school)?
He has 30 total contacts, of which 16 are from school. So
[tex]P = \frac{16}{30} = 0.5333[/tex]

OA (2,00)
OB. (5,00)
OC. (-00, 2)
OD. (-0,5)
Answer:a
Step-by-step explanation:
The function h(x) is increasing on the interval (5, ∞).
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
The function h(x) = |x − 5| + 2 is increasing on an interval where the derivative is positive.
If x < 5, then h(x) = -(x-5) + 2 = 7-x, and if x > 5, then h(x) = x - 5 + 2 = x - 3. Thus,
h'(x) =[tex]\left \{ {{ -1, for x < 5} \atop { 1, for x > 5}} \right.[/tex]
Since h'(x) is positive for all x > 5, the function h(x) is increasing on the interval (5, ∞).

What is the perimeter of the figure below?
r
X
r-2
Answer:
Perimeter = 5x - 2
Step-by-step explanation:
Perimeter of the figure = sum of all its side lengths
Thus:
Perimeter = (x - 4) + (x + 3) + (x - 2) + x + (x + 1)
Perimeter = x - 4 + x + 3 + x - 2 + x + x + 1
Collect like terms
Perimeter = x + x + x + x + x - 4 + 3 - 2 + 1
Perimeter = 5x - 2
