[tex]\frac{3}{10} =\frac{12}{y}[/tex]

3 × y = 12 × 10

3y = 120

y = 40

Answer: No solution

Step-by-step explanation:

-3x+3y=4

-x+y=3

We will rewrite the first equation and then substitute it into the second equation since we are solving by substitution.

Rewriting

-3x + 3y = 4

3y = 4 + 3x

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

Substituting

-x + y = 3

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

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

[tex]\frac{4}{3}[/tex]  = 3

Hmmm, this doesn't look right, does it? This means there is no solution.

-> We can also see this when we graph the two equations, they never intersect.

The possible line of best fit is given by y = -0.5x + 10

A linear equation is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept.

Let y represent the students still participating in the final round while x represent the number of spelling words attempted.

Since the line of best fit has a negative, linear association, this means that the slope is negative. A possible linear function is:

y = -0.5x + 10

The possible line of best fit is given by y = -0.5x + 10

Speed = Distance / time

Distance is fixed so speed x time = constant

speed1 x time1 = speed2 x time2

speed1/speed2 = time2/time1

speed1/speed2 = 20/27

time2/time1 = 20/27

Percentage decrease in time = (time1 - time2)/time1 x 100%

= (1 - time2/time1) x 100%

= (1 - 20/27) x 100%

= 7/27 x 100%

= 25.9%

Let the equation of the angle bisector be y = mx + C

It is the angle bisector so its slope, m, is half way between slope of the two lines:

y = 2; slope = 0

y = 4x - 2; slope = 4

So m = (0 + 4) / 2 = 2

y = 2x + C

It is the angle bisector so the line must pass through intersection of the two lines:

y = 2 and y = 4x - 2

4x -2 = 2

x = 1

Intersection point is at x = 1 and y = 2

Substitute back into y = 2x + C

2 = 2(1) + C

C = 0

So the equation is y = 2x

Based on the residual plot, the linear model is not appropriate because  the residuals are relatively large.

A residual plot is a graph that shows the residual values on the y-axis and fitted values on the x-axis. The aim of a residual plot is to check if the residual are consistent with random error.  When the residuals center on zero, it means that the model’s predictions are correct on average. If this is not the case, the model's predictions are not correct.

Answer:

13, they could all split up into groups of 1

Step-by-step explanation:

The greatest common factor between the expressions is 6v.

We have the expressions:

We can see that the smallest power of "v" is 1, and it appears on the second expression, so the greatest common factor will be a number times v.

To get the number, we need to find the greatest common factor between the 3 coefficients.

12, 30, and 42.

Rewriting these 3 numbers we can see that:

12 = 2*2*3

30 = 2*3*5

42 = 2*3*7

In all the cases we can see that the factor 2*3 appears, so that is the greatest common factor between the coefficients.

So we can conclude that the greatest common factor between the expressions is:

2*3*v = 6v

And we can rewrite:

The value of x is 10.

What is Mean ?

Mean is the average value of the data, It depicts the central tendency of the data.

The numbers are 4 ,3,3,x

The Mean of the data is 5

The Mean = ( Sum of Data) / ( Number of Data)

Mean = (4+3+3+x ) / 4

5 = (10+x)/4

20 = 10+x

x = 10

Therefore, the value of x is 10.

Answer:

h > 2

Step-by-step explanation:

It may look hard, but it is not really.

1. Solve

Here we have the equation 5+h>7.

All we have to do to find h is to subtract 5 from both sides.

5+h>7

-5     -5

When you subtract 5 from both sides, you get

5 - 5 = 0

7 - 5 = 2

All is left is 0+h>2, or h > 2.

2. Substitute

To make sure, (I do this but you can if you want to) I will substitute.

The values of h have to be greater than 2. So, Let's substitute 3.

5 + h > 7 --> 5 + 3 > 7

It's simple math.

5+3=8

8>7

Now, also to confirm, let's try a value less than 2, 1.

5 + h > 7

5 + 1 > 7

6 > 7 is not true, so it is confirmed that anything less than 2 is not true and anything greater is true.

Hence, h > 2

Given -

↠ the length of a rectangle is 11 m less than three times the width (let the width be x then length = 3x - 11)

↠the area of the rectangle is 42 m².

To find -

the dimensions of the rectangle.

Solution -

As we know,

area of rectangle = length × width

➟ 42 = (3x - 11) x

➟ 42 = 3x² - 11x

➟ 3x² - 11x - 42 = 0

now splitting the middle term to find the value of x,

➟ 3x² - (18 - 7)x - 42 = 0

➟ 3x² - 18x +7x - 42 = 0

➟ 3x (x- 6) +7(x - 6) = 0

➟ (3x + 7)(x - 6) = 0

➟ x = -7/3, 6

➟ x = 6

We will take the value of x as 6 because the value of dimensions can never be in negative.

Hence, length = 3 × 6 - 11 = 7 cm and width = 6 cm

[tex]y = 2\sqrt{10}[/tex]

Step-by-step explanation:

In left small right triangle: we have the square of left side = 5^2 + y^2 = 25 + y^2

In right small right triangle: we have the square of right side = 8^2 + y^2 = 64 + y^2

In the large right triangle, we have (25 + y^2) + (64 + y^2) = (5 + 8)^2

89 + 2y^2 = 13^2 = 169

2y^2 = 169 - 89 = 80

y = 80/2 = 40

so

[tex]y=\sqrt{40} = 2\sqrt{10}[/tex]

Cada estudiante debe pagar 2.88 pesos para consumir 3 rebanadas.

Si sabemos que existen 52 alumnos que quieren comer 3 rebanadas, entonces tenemos que el total requerido de rebanadas es de 156 rebanadas.

Además, si dos pizzas tienen 16 rebanadas y cuestan 150 pesos, entonces el número de rebanadas dividido por el par de cajas es 1.025 pares. Por ende, quedarían 4 rebanadas sobrantes que pueden ser compartidas por alguien más o vendidas a alguien más a cambio de una tarifa módica.

Por último, el monto a pagar por cada estudiante es el precio de la oferta dividido el número de estudiantes. En consecuencia, cada estudiante debe pagar aproximadamente 2.88 pesos.

Answer:

Step-by-step explanation:

If it has the same shape, it has the same points, it has the same equation/expression.

The equation of the given graph is F(x) = x² - 5. The correct answer is an option (A).

A parabola is a U-shaped curve this is drawn for a quadratic function.

The graph of F(x) = x² - 5 is a parabola that opens upward and is shifted 5 units down compared to the graph of G(x) = x².

The vertex of the parabola is located at (0,-5) instead of (0,0) as it is for the graph of G(x) = x².

The shape of the parabola is the same as that of G(x) = x², but it is translated downward by 5 units.

This means that the minimum point (vertex) of F(x) is located 5 units below the minimum point (vertex) of G(x).

Thus, the correct answer is an option (A).
