Answer:

Step-by-step explanation:

5x+9y=-3             Multiply both sides by 8

40x+72y=-24

-53x-8y=-3  Multiply both sides by 9

-477x -72y= -27

sum the equations vertically to eliminate one variable  

40x+72y= -24

-477x-72y= -27       (the y cancels out )

-477x =-51                (-24 + -27=-51)

-477x=-51 / -477       divide both sides by -477

x =51/437

5x 51/437=9y= -3   substitute the value of x

y= -174 /437

(x,y) = (51/437,  -174/437)

Explicación paso a paso:

Sean enteros impares consecutivos:

x, x + 2, x + 4

3 (x + 2) = (x + x + 4) + 5

3x + 6 = (2x + 4 + 5)

3x + 6 = 2x + 9

3x - 2x = 9 - 6

x = 3

Por lo tanto,

x = 3; (x + 2) = 3 +2 = 5; x + 4 = .3 + 4 = 7

Step-by-step explanation:

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

With the regrouping strategy, we get,

50 x 10; 7 x 10; 50 x 8; 7 x 8

Option B is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

57 x 18

This can be written as,

(50 + 7) x (10 + 8)

Simplifying we get,

(50 x 10) + (50 x 8) + (7 x 10) + (7 x 8)

Now,

With the regrouping strategy, we get,

(50 x 10)

(50 x 8)

(7 x 10)

(7 x 8)

Thus,

With the regrouping strategy, we get,

50 x 10; 7 x 10; 50 x 8; 7 x 8

Option B is the correct answer.

Answer:The slope is 6/7

Step-by-step explanation:

when finding the slope you will need to move the 6x to the other side of the equation by subtracting which gives you 7y=14-6x and all that is left is to divide by 7 which gives y=14-6/7y

Answer:

6x - 7y = 14

⇔ 6x - 14 = 7y

⇔ 6/7.x - 2 = y

=> the slope is 6/7

Step-by-step explanation:

The greatest number of rows that can be formed in the garden will be 3.

The Highest Common Factor (HCF) of two numbers is the highest possible number that is divisible by both numbers.

In other words, the highest common factor is the common factor between the two numbers but it should be the highest among all common factors.

As per the given,

Ramon has 27 tomato plants, 15 cucumber plants, and 6 basil plants.

Factors of 27 = 1, 3, 9, and 27.

Factors of 15 =  1, 3, 5 and 15

Factors of 6 = 1, 2, 3 and 6

The GCF of 27,15 and 6 is 3.

Thus, only three raws are possible.

Hence "The greatest number of rows that can be formed in the garden will be 3".

Answer:

The value of x is 3

Step-by-step explanation:

∵ Quadrilateral ABCD is congruent to quadrilateral JKLM

∴ AB = JK and BC = KL

∴ CD = LM and AD = JM

∵ BC = 8x + 7

∵ KL = 31

∵ BC = KL

→ Equate their right sides

∴ 8x + 7 = 31

→ Subtract 7 from both sides

∵ 8x + 7 - 7 = 31 - 7

∴ 8x = 24

→ Divide both sides by 8 to find x

∴ [tex]\frac{8x}{8}[/tex] = [tex]\frac{24}{8}[/tex]

∴ x = 3

∴ The value of x is 3

The slope between (5, 13) and (9, 10) is:

Step-by-step explanation:

Given the points

Finding the slope between (5, 13) and (9, 10)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{10-13}{9-5}[/tex]

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

Therefore, the slope between (5, 13) and (9, 10) is:

Let x be the number we are searching for.

(3/4)x = 1/10

Answer:

(-4,3) or X=-4, y=3

Step-by-step explanation:

when solving for the first variable once you have the result then substitute the result into the other equation.

Answer:

Any line with a slope of 8 is parallel to y = 8x + 11.  Some examples are:

y = 8x + 5

y = 8x + 1000

y = 8x +9

It doesn't matter what the y-intercept as long as the slope remains the same for a parallel line.

Answer:

Like the other person said, any line that has the same slope (8) will be parallel.

Step-by-step explanation:

Let us write the factors of 100. A factor of 100 can only be a multiple of five if it is divisible by five.

Factors of 100 ⇒ numbers divisible by 100 ⇒ 1, 2, 4, 5, 10, 20, 25, 50, 100

When checking each factor of 100;

⇒ Five factors are multiples of 5.

Therefore, five factors of 100 are multiples of 5.

Answer:

  y = 2x + 4

Step-by-step explanation:

You have the graph, so you can read the slope and y-intercept from it. The line goes up 2 units for each unit to the right, so the slope is ...

  slope = rise/run = 2/1 = 2

The y-intercept is where the graph crosses the y-axis, at y=4.

The slope-intercept form of the equation for a line is ...

  y = mx + b

where m is the slope (2) and b is the y-intercept (4). Your equation is ...

  y = 2x +4
