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

so. what have you got so far?

How can a digit have no value?

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

Hope this helps!

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.

Step-by-step explanation:

0.8 is out of 1.0 so 0.8 + 0.2 = 1.0 and same for 8/10

Answer: True

Step-by-step explanation:

In order to see if the two given numbers are equal to each other, you need to turn one of them into either a fraction or a decimal so both of them are the same and you are able to compare.

In order to turn [tex]\frac{8}{10}[/tex] into a decimal, you divide 10 by 8.

8 ÷ 10 = 0.8

Both of the decimals are the same therefore the numbers are equal to each other and the statement is true.

Answer:

1 watch cost 19,200 (76800/4=19200)

9 watches cost 172,800 (9×19200=172800)

Step-by-step explanation:

Answer:

$172.8

Step-by-step explanation:

divide 76.800 by 4 to figure out how much each watch cost. Than once you got that answer multiply by 9 to find out the cost of 9 watches

76.800÷4= 19.2

19.2×9= 172.8

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.

Answer:

  5/2

Step-by-step explanation:

The ratio of the diameters is equal to the scale factor:

  sf = (15 in)/(6 in) = 5/2

The scale factor used to create circle A' is 5/2.

Let w represents the weight of the first box placed on the scale and y represent the weight of the second box.

The second box weigh 10 pounds less than the first box. Hence:

y = w - 10

-w + y = -10     (1)

The two boxes weigh 48 pounds. hence:

w + y = 48       (2)

Solving both equations gives:

w = 29, y = 19

The first box weighs 29 pounds while the second box weighs 19 pounds.
