Answer:

A. The blue line represents the equation 2x-3y=6, and the solution to the system of equations is (–6, –2).

Step-by-step explanation:

Here we have the system:

2x - 3y = -6

y = -(1/3)*x - 4

First, remember that if the slope is negative, then the equation is decreasing.

So, for the second equation, as x increases, y decreases, then the line of the second equation is the red one (because the red one decreases).

So the blue one represents the equation 2x - 3y = -6

Also remember that the solution of a system of equations is the point where the graphs of the equations intersect, here we can see that the intersection happens at the point (-6, - 2)

This means that the solution of the system is  (-6, - 2)

From this, we can see that the correct option is:

A. The blue line represents the equation 2x-3y=6, and the solution to the system of equations is (–6, –2).

A: The blue line represents the equation 2x-3y=6, and the solution to the system of equations is (–6, –2).

obtuse angle means the angle is larger than 90 degrees

Answer:

The coordinates of the P' point are (-17.3,-10).

Step-by-step explanation:

We can use the components of the vector from 0 to P point. We know that the diameter is 40 meters, so the magnitude of the vector will be 20 m.

Now, the angle from the negative x-direction to the vector is 210°-180° = 30°.

The x-component of the vector will be:

[tex]V_{x}=-Vcos(30)[/tex]

[tex]V_{x}=-20cos(30)=-17.32\: m[/tex]

It is negative because the component is in the negative x-direction.

The y-component of the vector will be:

[tex]V_{y}=-Vsin(30)[/tex]

[tex]V_{y}=-20sin(30)=-10\: m[/tex]

It is negative too because the component is in the negative y-direction.

Therefore, the coordinates of the P' point are P'(-17.3,-10)

Hello! answer: 30

Step-by-step explanation:

13 × 13 = 169

5 × 5 = 25

169 - 25 = 144

12 × 12 = 144 therefore 12 is the missing leg

so we will use this to find the area so...

12 × 5 = 60 60 ÷ 2 = 30 therefore the answer is 30 hope that helps!

C. y = 3x - 4

Step-by-step explanation:

Given coordinates:

(2, 2), (3, 5), (5, 11), (7, 17)

The equation of any straight line is

y = mx + c

Where

m = Gradient

c = Constant

Gradient = y2 - y1/x2 - x1

Substitute any two values of y with the respective values of x.

Gradient = 17 - 2/7 - 2

= 15/5

= 3

Substitute the gradient into the general formula.

y = 3x + c

Substitute any value of the coordinate to the equation

2 = 3(2) + c

2 = 6 + c

c = -4

From y = mx + c,

substitute the values of m, the gradient, and c, the constant.

y = (3)x + (-4)

y = 3x - 4

Answer:

[tex]2x + y = 11 - - - (a) \\ 4x - y = 25 - - - (b) \\ (a) + (b) : \\ 6x + 0y = 36 \\ 6x = 36 \\ x = 6[/tex]

bestie that is worth more than 15 pts

Answer:

Step-by-step explanation:

The total amount of students is 240

240(50%) = 120 > 60 so, the first true or false is False

240(5%) = 12 = 12 so, the the second true or false is True

240(60%) = 144 = 144 so, the third true or false is True

132 + 12 = 144

Answer:

c. 0.17

Step-by-step explanation:

The bag have 4 + 2 + 6 = 12 balls.

There are 2 red marbles, in 12, the probability to take one red is 2/12. Is important to remember that the first marble was replaced before the second outcome, so the chance for the second is also 2/12:

2/12 = 1/6 = 0.1666 ≈ 0.17

The expected value of the random variable that assigns  the number of red marbles to each outcome is 0.17.

Probability is used to estimate how likely an event would happen. The probability the event occurs with certainty is 1 and the probability that the event does not occur with certainty is 0.

Expected value = number of red marbles / total number of marbles

2/12 = 0.17

Answer:

3x + 2y = 29

5x + 2y = 35

Step-by-step explanation:

Let

x = cost of one-inch binders

y = cost of two-inch binders

Rasheed:

3x + 2y = 29 (1)

Matar:

5x + 2y = 35 (2)

3x + 2y = 29 (1)

5x + 2y = 35 (2)

Using elimination method, subtract (1) from (2)

5x - 3x = 35 - 29

2x = 6

x = 6/2

x = 3

Substitute x = 3 into (1)

3x + 2y = 29 (1)

3(3) + 2y = 29

9 + 2y = 29

2y = 29 - 9

2y = 20

y = 20/2

y = 10

Answer: Commutative Property of Addition

This property says that A+B = B+A. The order of addition doesn't matter.

As an example, 2+3 = 3+2 since both sides evaluate to 5.

Answer:

The value of x is incorrect he should be using 28/21 instead of 21/28

Step-by-step explanation:

tan = opp/adj

tanx = 28/21

The value of x is incorrect he should be using 28/21 instead of 21/28

Answer:

A) The value of x is incorrect. He should be using 28/21 instead of 21/28.

Step-by-step explanation:

Recall that [tex]tan\theta=\frac{opposite}{adjacent}[/tex]. This means that the correct setup would be [tex]tan\theta=\frac{28}{21}[/tex] since 28 is opposite of x° and 21 is adjacent to x°. Thus, your solution would be [tex]x^{o}=tan^{-1}(\frac{28}{21})=53.13010235^o\approx53.1^o[/tex]

Answer:

5.83

Step-by-step explanation:

Given data

x1= -8

y1= 0

x2= -5

y2= -5

The expression for the distance between two points is

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((-5-(-8))²+(-5-0)²)

d=√((-5+8)²+(-5²)

d=√(3)²+25)

d=√9+25

d=√34

d= 5.83

Hence the distance between the points is 5.83
