Step-by-step explanation:

The equation that models this situation is z = 7.9y + 12.

A linear equation is a function that has a single variable raised to the power of 1.  An example is x = 4y + 2.

Where:

From the equation given, 12 would be the constant, the independent variable would be 7.9 and z would be the dependent variable.

z = 7.9y + 12

Using the principle of probability, the likelihood that Shreya wins by getting 2 blues and 1 red is 0.416

Creating an area model for the first two spinners :

___ G _ B _ B _ R _R _R

R_RG_RB_RB_RR_RR_RR

R_RG_RB_RB_RR_RR_RR

B_BG_BB_BB_BR_BR_BR

B_BG_BB_BB_BR_BR_BR

B_BG_BB_BB_BR_BR_BR

B_BG_BB_BB_BR_BR_BR

G_GG_GB_GB_GR_GR_GR

G_GG_GB_GB_GR_GR_GR

Creating an area model or tree diagram for the third spinner would result in a sample space of (48 × 12) = 576 combinations.

However, the probability that Shreya would win can be obtained thus :

To win he needs to pick get 2 blues and 1 red in any order :

3! = 3 × 2 × 1 = 6 ways

P(BBR) = 1/3 × 4/8 × 5/12 = 0.0694444

P(winning) = 6 × 0.0694444 = 0.416

Therefore, the probability that Shreya wins is 0.416.

Answer:

6

Step-by-step explanation:

You can solve this using Pythagorean Theorem;

a² + b² = c²

c is always the hypotenuse or the longest length in the triangle which is always opposite to the forming 90° angle.

a and b values can be the other 2 legs, doesn’t matter which one is which

we are given;

a = 8

c = 10

a² + b² = c²

(8)² + b² = (10)²

64 + b² = 100

b² = 100 - 64

b² = 36

√b² = √36

b = 6

Therefore the answer = 6

Answer:

a₃₂ = - 59

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 3 and d = a₂ - a₁ = 1 - 3 = - 2 , then

[tex]a_{n}[/tex] = 3 - 2(n - 1) = 3 - 2n + 2 = - 2n + 5

Then

a₃₂ = - 2(32) + 5 = - 64 + 5 = - 59

Answer:

y<x+1

Step-by-step explanation:

Plug your slope and a point into the formula y = mx + B, in which "m" is the slope, (x, y) is a point on the line and "b" is the y-intercept, to find the equation governing the inequality line. Plugging in (0, 0), you obtain 0 = 0 + b, so b = 0. Rewriting the equation, you obtain y<x+1

Answer:

I think C or D not sure about the question answer

He was earning 3562 each hour.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Kyle Lowry earned $31.2 million.

So, In each month he read

= 31200000 / 12

= $2,600,000

and, in each day she earn

= 2, 600, 000 / 30

=86,666.666

and, in each hour she earn

= 2, 600, 000 / 24

= 3611

Hence, He was earning 3562 each hour.

Answer:

Question 1) Option C: 2(2x+1) = y, y = 2x + 8.

Question 4) Option C:  y = x + 4,  2y = 2x + 8

Step-by-step explanation:

The graph of perpendicular lines will show an intersection of two lines at a single point, forming 90° adjacent angles. Since perpendicular lines intersect at exactly one point, then it means that they will have one solution.  Additionally, perpendicular lines have negative reciprocal slopes for which multiplying the slopes of both lines result in a product of -1.

Lines that have the same slope and y-intercept. Therefore, they are equivalent equations that will result in an infinitely many solutions. The graph of these lines will coincide on top of each other, as if they are the same line.  The systems of linear equations that result in an infinitely many solutions are dependent and consistent. They are dependent if they have an infinite number of solutions, and consistent because they have at least one solution.

Parallel lines have the same slope.  A systems of linear equations whose graph involve parallel lines have no solution, as there is no point of intersection between those two lines.  Therefore, parallel lines have no solution, making it an inconsistent system.

We must transform these equations in its slope-intercept form, y = mx + b, which will allow us to easily determine the type of lines a given system has based on their slopes.

Equation 1:  2x + y = 10

Equation 2: y = −2x + 8

Transform Equation 1 to slope-intercept form:

2x + y = 10

Subtract 2x from both sides:

2x - 2x + y = - 2x + 10

y = -2x + 10  ⇒ This is the slope-intercept form of Equation 1.

Since Equations 1 and 2 have the same slope, but different y-intercepts, then it means that they are parallel lines that have no point of intersection.

Transform both equations to slope-intercept form:

Equation 1:  2x + 4y = 10

                   [tex]\large\bf\sf{y\:=\:-\frac{1}{2}x\:+\:\frac{5}{2}}[/tex]  ⇒ This is the slope-intercept form of Equation 1.

Equation 2:  2(x+2y) = 10

Distribute 2 into the parenthesis:

2(x+2y) = 10

2x + 4y = 10  ⇒ It is clear at this point that this equation matches Equation 1. Thus, the slope-intercept form of Equation 2 will be the same:

[tex]\large\bf\sf{y\:=\:-\frac{1}{2}x\:+\:\frac{5}{2}}[/tex]  ⇒ Slope-intercept form of Equation 2.

It turns out that Equations 1 and 2 are equivalent, as they have exactly the same slope and y-intercept. Therefore, they have coinciding lines and have infinitely many solutions.

Transform both equations to slope-intercept form:

Equation 1:  2(2x+1) = y

                    y = 4x + 2  ⇒ Slope-intercept form of Equation 1.

Equation 2:  y = 2x + 8  

Equation 1: y = 10 − 2x

                    y = − 2x + 10  ⇒ This is the slope-intercept form of Equation 1.

Equation 2:  y = −2x + 7

Since Equations 1 and 2 have the same slope, but different y-intercept, then it means that they are parallel from each other.

Out of all the given four options, Option C seems to be the correct answer, since the given system has varying slopes and y-intercept.  Therefore, the correct answer for Question 1 is Option C:  2(2x+1) = y, y = 2x + 8.

For Question 4, I will not elaborate as thoroughly as in Question 1 since I'll be using the same techniques.

Equation 1:  2x+ 7x + y = 6

Combine like terms:

2x+ 7x + y = 6

9x + y = 6

Subtract 9x from both sides:

9x - 9x + y = - 9x + 6

y = - 9x + 6 ⇒ Slope-intercept form of Equation 1.  

Equation 2: y = 9x + 6

Option A Explanation:

Equations 1 and 2 have different slopes and the same y-intercept. This implies that they will have a point of intersection = one solution. However, they don't have perpendicular lines because their slopes are not negative reciprocal of each other.  Hence, Option A is not a valid answer for  question 4.

Equation 1:  y = 5x + 7

Equation 2:  y = 2x + 8

Option B explanation:

Similar to Option A, Equations 1 and 2 have different slopes and varying y-intercepts. Since they are not parallel from each other, and do not have coinciding lines, then Option B is not a valid answer for  question 4.

Equation 1:  y = x + 4

Equation 2:  2y = 2x + 8

Transform Equation 2 to Slope-intercept form:

Divide both sides by 2 to isolate y:

[tex]\displaytext\mathsf{\frac{2y}{2}\:=\:\frac{2x\:+\:8}{2}}[/tex]

y = x + 4  ⇒ This is the slope-intercept form of Equation 2.  

Option C explanation:

Equations 1 and 2 are equivalent, as they have exactly the same slope and y-intercept. They also have coinciding lines, having infinitely many solutions.  

Equation 1:  7x − y = 10

                    y = 7x - 10  ⇒ This is the slope-intercept form of Equation 1.

Equation 2:  y = 6x + 8

Option D explanation:

Similar to Option B, Equations 1 and 2 have different slopes and varying y-intercepts. Since they are not parallel from each other, and do not have coinciding lines, then Option D is not a valid answer for  question 4.
