Answer:

m:number that is multiplied on x  b:the y-intercept

Step-by-step explanation:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".

In the equation y = mx + b, m represents slope and b represents y intercept.

In the equation y = mx + b, the variables "m" and "b" represent coefficients or constants. Specifically:

"m" represents the slope of the line. It determines the steepness or inclination of the line.

The slope indicates how much y (the dependent variable) changes for each unit change in x (the independent variable).

"b" represents the y-intercept of the line. It is the value of y when x is equal to zero.

The y-intercept is the point where the line intersects the y-axis.

m and b define the equation of a straight line in slope-intercept form, where "m" is the slope and "b" is the y-intercept.

The first 5 are

Given:

The system of equations is

[tex]3x-2y=7[/tex]

[tex]6x-4y=14[/tex]

To find:

The correct statement for the given system of equations.

Solution:

On comparing the given equations and general form of linear equation, i.e., [tex]ax+by+c=0[/tex], we get

[tex]a_1=3,b_1=-2,c_1=-7[/tex]

[tex]a_2=6,b_2=-4,c_2=-14[/tex]

Here,

[tex]\dfrac{a_1}{a_2}=\dfrac{3}{6}=\dfrac{1}{2}[/tex]

[tex]\dfrac{b_1}{b_2}=\dfrac{-2}{-4}=\dfrac{1}{2}[/tex]

[tex]\dfrac{c_1}{c_2}=\dfrac{-7}{-14}=\dfrac{1}{2}[/tex]

Since, [tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}[/tex], therefore, the two equations are equivalent and the system has infinitely many solutions.

Hence, the correct option is b.

Answer:

0.8

Step-by-step explanation:

Each increase is 1.6 apart. Because they're going by two cycles just divide that by two and you get 0.8

Answer:

Step-by-step explanation:

Since, speed of a car = [tex]\frac{\text{Distance traveled}}{\text{Time taken}}[/tex]

From  the graph attached,

A point (1, 60) lies on the line shown in graph.

At this point speed of the car = [tex]\frac{\triangle y}{\triangle x}[/tex]

                                                [tex]=\frac{60-0}{1-0}[/tex]

                                                = 60 miles per hour

But Billy says the speed of the car is [tex]\frac{1}{60}[/tex] miles per hour.

So the error in the Billy's answer is that he has used the wrong formula to calculate the speed.

(As per Billy, speed = [tex]\frac{\text{Time taken}}{\text{Distance covered}}[/tex])

=======================================================

Explanation:

Let n be the degree of the numerator

Let d be the degree of the denominator

If n < d, then the limit at infinity is always 0. This is because the denominator is growing faster compared to the numerator. I suggest looking at a table of values to see this in action.

In this case, n = 3 and d = 4, so we see that n < d is the case here. So that's why the answer is 0.

Answer:

(6/11, 16/11)

Step-by-step explanation:

While it's fairly obvious that you're supposed to "solve this system of equations," it'd be clearer if you were to say so specifically.  Also, reduce ambiguity by using parenthes:  You meant either (5/3)x or 5/(3x).  Which one?  I'm assuming it's (5/3)x.

Then our system is:

(5/3)x - 2y = -2

      x  +  y =  2

Let's eliminate y through addition/subtraction.  Multiply the 2nd equation through by +2:

(5/3)x - 2y = -2

     2x  + 2y = 4

------------------------

(11/3)x       =  2

Multiplying both sides by 3 eliminates the fractional coefficient:

11x = 6

Then x = 6/11.  Now we must solve for y:

-(6/11) + y = 2

Multiplying 2 by 11/11 yields:

-(6/11) + y = 22/11.

This simplifies to y = 16/11

Thus, the solution of this system is

(6/11, 16/11)

Answer:

Step-by-step explanation:

3x + 49 = 7x - 23

4x = 72

x = 18

11y - 1 = 3(18)

11y = 55

y = 5

The value of x is 18 and y is 5.

Following are the properties of parallel lines,

Given:

<1 = 7y -23

<2 = 11y -1

<3 = 3x

Using corresponding angle

7x - 23 = 3x + 49

4x = 72

x = 18

again, Using corresponding angle

3x = 11y - 1

3(18) = 11y - 1

11y = 55

y= 5

Hence, the value of x is 18 and y is 5.

Answer:

x = 574 and x = - [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

(1)

0.25x = 143.5 ( isolate x by dividing both sides by 0.25 )

x = 574

(2)

- 4x + [tex]\frac{1}{2}[/tex] = 3 [tex]\frac{1}{2}[/tex] ( subtract [tex]\frac{1}{2}[/tex] from both sides )

- 4x = 3 ( divide both sides by - 4 )

x = - [tex]\frac{3}{4}[/tex]

x = 574, How did I get this answer? I simply divided 143.5 by 0.25 and you get 574, which will be the missing number (also known as x.)

But, before you write this down as your answer - how can we check if 574 is correct?

Well we're going to have to do the reverse of dividing, which'll be multiplying.

Multiply 0.25 by 574! (It does equal 143.5), Therefore, you have checked your answer and now you know it is correct.

This equation simplifies to [tex]\frac{2x-1}{4} = \frac{7}{2}[/tex]. Let's go on ahead and figure this problem out step-by-step!

First, we have to cross multiply. As shown here:

(2x-1) × (2) = 7 × 4x

4x - 2 = 28x

After that, we're going to have to subtract 28x from both sides of the equation.

4x - 2 - 28x = 28x - 28x

-24x - 2 = 0

Next, add 2 to both of the sides.

-24x - 2 + 2 = 0 + 2

- 24x = 2

On your last step before finding out what x is, the final thing we've got to do is divide both sides by -24.

[tex]\frac{-24x}{24} = \frac{2}{-24}[/tex]

x = [tex]\frac{-1}{12}[/tex]. This is your solution for #2.

Answer:

Adults =193

children=52

Step-by-step explanation:

Step one:

let the number of tickets adults be x

and the number of tickets children be y

x+y=245--------1

6.5x+3y=1410.5---2

Step two:

solve the system of equation using substitution

x+y=245

x=245-y

put x=245-y in equation 2 we have

6.5(245-y)+3y=1410.5

1592.5-6.5y+3y=1410.5

-6y+3y=1410.5-1592.5

-3.5y=-182

y=182/3.5

y=52

put y=52 in x=245-y

x=245-52
