Answer:

Consistent independent

x + y = 0  and  -x + y = -8

Step-by-step explanation:

Inconsistent: parallel lines, no solutions

Consistent dependent: same line, infinite solutions

Consistent independent: intersects at one point, one solution

Therefore, the pair of lines are Consistent independent

From inspection of the diagram:

One line has a negative slope and the other a positive slope.

One has a y-intercept of 0 and the other a y-intercept of -8.

Therefore, the solution is x + y = 0  and  -x + y = -8

Because:

x + y = 0  ⇒  y = -x  (neg slope, y-intercept of 0)

-x + y = -8  ⇒  y = x - 8  (pos slope, y-interecept at -8)

Answer:

Step-by-step explanation:

You got it right: the point (0, -1) is another point on the graph of y = 3x - 1.

Substituting 0 and -1 back into the equation, y = 3x - 1:

-1 = 3(0) - 1

So the pint is also a solution to the equation.

Answer:

4/7

Step-by-step explanation:

The conditional probability of A and B happening : P(AnB) is 1/6, and the conditional probability of B happening : P(B) is 7/24, the probability of A happening is 1/6 : 7/24 = 4/7

P(A/B) = Given that B occurs, find the probability of A occuring

Question 11

[tex]\sin(\theta)=\dfrac{\textsf{opposite side}}{\textsf{hypotenuse}}[/tex]

Given:

[tex]\implies \sin(x)=\dfrac{7}{13}[/tex]

[tex]\implies x=\sin^{-1}\left(\dfrac{7}{13}\right)[/tex]

[tex]\implies x=32.6\textdegree \textsf{ (nearest tenth)}[/tex]

Question 12

[tex]\sin(\theta)=\dfrac{\textsf{opposite side}}{\textsf{hypotenuse}}[/tex]

Given:

[tex]\implies \sin(64\textdegree)=\dfrac{x}{30}[/tex]

[tex]\implies x=30\sin(64\textdegree)[/tex]

[tex]\implies x=27.0\textsf{ (nearest tenth)}[/tex]

Given that: √{11 + 4√(7)}

Let √{11 + 4√(7)} = √(x) + √(y)

Squaring on both sides then

= [√{11 + 4√(7)}]² = {√(x) + √(y)}²

= 11 + 4√(7) = x + y + 2√(xy)

= 11 + 2√(7 * 2²) = x + y + 2√(xy)

= 11 + 2√(7 * 2*2) = x + y + 2√(xy)

= 11 + 2√(7 * 4) = x + y + 2√(xy)

= 11 + 2√(28) = x + y + 2√(xy)

On comparing with both sides, we notice that:

⇛2√(xy) = 2√(28)

⇛ xy = 28

We know that

(x-y)² = (x+y)² - 4xy

(x-y)² = (11)² - 4(28)

(x-y)² = (11*11) - 112

(x-y)² = 121 - 112

(x-y)² = 9

x - y = √(9)

x - y = √(3*3)

On adding equation (1) and equation (2), we get

x + y = 11

(+) x - y = 3

_______

2x = 14

Shift the number 2 from LHS to RHS, changing it's sign.

⇛x = 14/2

⇛x = 7/1

Simplify the fraction to get the value of x.

Now, substitute the value of x in equation (1) then

x + y = 11

⇛7 + y = 11

Shift the number 7 from LHS to RHS, changing it's sign.

⇛y = 11 - 7

Now, we have: x = 7 and y = 4

So,

√(x) + √(y) = √(7) + √(4) = √(7) + √(2*2) √(7) + 2

(Or)

√{11 + 4√(7)}

= √{11 + 2√(7*4)}

= √{11 + 2√(7)√(4)}

= √[{√(7)²} + {√(4)}² + 2√(7)√(4)

[since, (a+b)² = a² + 2ab + b²]

= √[{√(7) + √(4)}²]

= √(7) + √(4)

= √(7) + √(2*2)

Therefore, √{11 + 4√(7)} = √(7) + 2

Answer: Hence, the simplified form of √{11 + 4√(7)} is √(7) + 2

Area of 1 side: 3*3=9

Number of sides: 6

6*9=54

Answer:

54 square yards

Step-by-step explanation:

This is a cube, as the width, height, and length are all the same. To fine the surface area of a cube, simply find the area of one side and multiply it by six, as a cube has six sides.

[tex]Area = Width*Height\\Area = 3 * 3\\Area = 9[/tex]

The area of one side of the cube is 9 square yards. Therefore, the surface area of the entire cube is 6 x 9 or 54 square yards.

Answer:

In order to find the slope, we would need to format the coordinates like rise over run (y/x)

We find two points, (-6, 12) and (-5, 14)

Now we subtract the y coordinates from each other and do the same for the x coordinates

14 and 12 are our y coordinates so that will be our rise

-5 and -6 are x coordinates so that will be our run

50 cycles

Step-by-step explanation:

To find this out, we need to know how many cycles he sells a day. So as given he sells 5 cycles in 2 days, so what is half of five? While 2.5 cycles wouldn't make sense, lets use the variable to see what our answer would be approximately.

2.5 cycles x 20 days = 50 cycles.

So, in 20 days Josh would sell 50 cycles.

Answer:

50 cycles will be sold in 20 days

Step-by-step explanation:

2 days⇒5 cycles

1 day⇒5 divided by 2 days

20 days⇒5 cycles multiplied by 20 days divided by 2 days then the final answer is 50 cycles.
