Answers
Answer:
Options B and E.
Step-by-step explanation:
We want to see for which systems the point (-3, 2) is a solution (a solution of a system means that both equations intersect in that point).
The point (-3, 2) is a solution of the system only if this point belongs to both linear equations in the system.
Then for each system, we need to replace x by -3 and y by 2 in both equations and see if the equality is true or not.
A)
6x - y = 15
-3x + 4y = -18
In the first equation we have:
6*(-3) - (2) = 15
-18 - 2 = 15
-20 = 15
This is false, so we can discard option A.
B)
2x + y = -4
3x + 2y = -5
In the first equation we have:
2*(-3) + 2 = -4
-6 + 2 = -4
-4 = - 4
This is true, now let's look at the other equation.
3*(-3) + 2*(2) = -5
-9 + 4 = -5
-5 = - 5
This is also true, then the point (-3, 2) is a solution for both equations, then the point (-3, 2) is a solution for the system.
C)
x + 8y = 19
4x - 5y = 2
In the first equation we have:
(-3) + 8*(2) = 19
-3 + 16 = 19
13 = 19
This is false, then we can discard option C.
D)
8x + y = 22
-2x - 5y=4
In the first option we have:
8*(-3) + 2 = 22
-24 + 2 = 22
-22 = 22
This is false, so we can discard option D.
E)
5x - y = -17
x + 4y = 5
In the first option we have:
5*(-3) - (2) = -17
-15 - 2 = -17
-17 = -17
This is true, now let's look at the other equation:
(-3) + 4*(2) = 5
-3 + 8 = 5
5 = 5
This is also true, then the point (-3, 2) is a solution for both equations in the system, which means that the point (-3, 2) is a solution for the system.
Then the correct options are B and E.

Pisces is replacing paving stones for her inground pool. Her pool is 10m by 5m and is surrounded by a 1 1/2 border of paving stone. If each paving stone was 25 cm by 40 cm, in theory, how many paving stones will she need?
Answers
Answer:
The number of paving stones she needs is 540 paving stone
Step-by-step explanation:
The given dimensions of Pisces' inground pool = 10 m by 5 m
The thickness of the border surrounding the pool = 1 1/2
The dimensions of each paving stone = 25 cm by 40 cm = 0.25 m by 0.4 m
The length dimension of the pool and border = 10 + 2 × 1 1/2 = 13 m
The width dimension of the pool = 5 + 2 × 1 1/2 = 8 m
The total area of the paving stone, [tex]T_A[/tex] = Area of pool + border - Area of pool
∴ [tex]T_A[/tex] = 13 m × 8 m - 10 m × 5 m = 54 m²
The total area of the paving stone = 54 m²
The area of each paving stone, [tex]A_{EP}[/tex] = 0.25 m × 0.4 m = 0.1 m²/paving stone
The number of paving stones she needs, n = (The total area of the paving stone)/(The area of each paving stone)
∴ n = 54 m²/(0.1 m²/paving stone) = 540 paving stone.

Solve the equation 506x - 92y + 90 = 498 - 4x + 6y
Answers
506 x - 92 y + 90 = 498 - 4 x + 6 y
Geometric figure:
line
y = (255 x)/49 - 204/49
510 x - 98 y - 408 = 0
506 x - 92 y + 90 = 6 (y + 83) - 4 x
Real solution:
y = (255 x)/49 - 204/49
Solution:
y = (255 x)/49 - 204/49
Integer solution:
x = 49 n + 40, y = 255 n + 204, n element Z
Solution for the variable y:
y = 51/49 (5 x - 4)

PLZ HELP ASAP!! Given g(x)=f(x)+k, enter the value for k that transforms the function f into g?
What does k=
Answers
Answer:
k = -2
Step-by-step explanation:
firstly, let us examine the kind of transformation that we have
We have a transformation from (3,2) to (3,0) and (-3,0) to (-3,-2)
So, we are actually subtracting 2 from the values of f(x) to get the values of g(x)
This shows a vertical translation to the tune of 2 units in the downward direction
So, the correct answer here is that -2 is being subtracted from f(x) to give g(x)
Accordingly, the value of k in the question is -2

A central angle of a circle of diameter 6 cm measures 86°. What is the length of the intercepted arc?
A)
2.8 cm
B)
4.5 cm
C)
5.1 cm
D)
9 cm
Answers
Answer:
B)
4.5 cm
Step-by-step explanation:
The formula for arc length when our central angle is in degrees =
2πr(θ/360)
θ = 86°
Diameter = 6cm Radius = Diameter /2
Radius = 6cm/2 = 3cm
Hence,
Intercepted arc length = 2 × π × 3 (86/360)
= 2 × π × 3 × 0.2388888889
= 4.5029494701 cm
Approximately = 4.5 cm
Option B is the correct answer
