Answer:

13x - 8y

Step-by-step explanation:

Step 1: Write expression

(6x - y) + (7x - 7y)

Step 2: Combine like terms

13x - 8y

Answer:

The answer is

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1) [/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (6 , - 1) and slope - 1/2

So we have

[tex]y + 1 = - \frac{1}{2} (x - 6) \\ y + 1 = - \frac{1}{2} x + 3 \\ y = - \frac{1}{2} x + 3 - 1 \\[/tex]

We have the final answer as

[tex]y = - \frac{1}{2} x + 2 \\ [/tex]

Step-by-step explanation:

Answer:

-1/2

Step-by-step explanation:

The slope of a perpendicular line is opposite reciprocal. So the opposite of 2 is -2, and the reciprocal of 2 is 1/2.

Answer:

[tex]\boxed {\tt m= -\frac{1}{2}}[/tex]

Step-by-step explanation:

Perpendicular slopes are negative reciprocals.

First, let's find the slope of the line. The equation is:

y=2x+3

This line is in slope-intercept form: y=mx+b. m is the slope and b is the y-intercept. Therefore, 2 is the slope.

Now, find the perpendicular slope.

1. Negate the slope

The slope is 2. Negate the slope, or switch the sign. It becomes -2.

2. Find the reciprocal

To find the reciprocal, switch the numerator and denominator.

The slope -2 is equal to -2/1. Switch the top number and bottom number and the result is -1/2.

The perpendicular slope is -1/2

Answer:

Q(0) = -2

Q(1) = 2

Q(-2) = -34

Step-by-step explanation:

Step 1: Define

Q(x) = x³ - 3x² + 6x - 2

Q(0) is x = 0

Q(1) is x = 1

Q(-2) is x = -2

Step 2: Substitute and Evaluate

Q(0) = 0³ - 3(0)² + 6(0) - 2

Q(0) = 0 - 0 + 0 - 2

Q(0) = -2

Q(1) = 1³ - 3(1)² + 6(1) - 2

Q(1) = 1 - 3 + 6 - 2

Q(1) = -2 + 6 - 2

Q(1) = -4 + 6

Q(1) = 2

Q(-2) = (-2)³ - 3(-2)² + 6(-2) - 2

Q(-2) = -8 - 3(4) - 12 - 2

Q(-2) = -8 - 12 - 14

Q(-2) = -20 - 14

Q(-2) = -34

Answer:

Step-by-step explanation:

Given the inequality  4x - 2y < 22, to get the ordered pair of the inequality, we will have to set x = 0 and y = 0 and then solve for the corresponding inequalities as shown;

when x = 0;

4(0)-2y < 22

-2y < 22

Divide both sides by -2

-2y/-2 > 22/-2

y > -11

When y = 0

4x - 2(0)<22

4x < 22

x < 22/4

x < 11/2

Hence the ordered pair for the inequality expression are y > -11 and x< 11/2

Answer:

x = 55

Step-by-step explanation:

125 is a corresponding angle to the supplesmntary angle of x. ( the angle next to x, the one that completes x to make it 180, is the same value as 125)

180 - 125 = 55

x = 55

- hope this makes sense

Based on the consecutive exterior angles theorem, the value of x is calculated as: 55°

Therefore,

x = 180° - 125°

x = 55°

Answer:

Step-by-step explanation:

12). From the picture attached,

     Supplementary angle of the angle measuring 113° = 180° - 113° = 67°

     Since, angles measuring 67° as shown in the figure are the alternate interior angles,

     Therefore, by the converse of alternate interior angles theorem, lines j and k will be parallel.

13). Angles formed on the one side of the parallel lines and the transverse line are equal in measure (90°).

   Therefore, by the converse of corresponding angles postulate, lines j and k will be parallel.

Answer: sq rt 136

Step-by-step explanation:

The Pythagorean theorem is a basic relationship between the three sides of a right triangle in Euclidean geometry. The length of the line is √136. Thus, the correct option is D.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The size of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides, according to this rule.

As per the given graph, the vertical length of the line is 6 units, while the horizontal length of the line is 10 units. Therefore, using the Pythagorean theorem we can write the length of the line as,

Length² = 6² + 10²

Length = √(36 + 100)

Length = √136

Hence, the length of the line is √136. Thus, the correct option is D.

Answer:

[tex](x-4)^{2}[/tex]>0

[tex](x-4)^{2}[/tex]+4>0

so the function is always positive.

Step-by-step explanation:

As [tex](x-4)^{2}[/tex] always positive, because when you square numbers you will get always a positive number.

So [tex](x-4)^{2}[/tex]+4>0, because the (+4) will not effect the answer as (x-4)^{2} will be positive.

Answer:

total number of students is  2500

ratio is 18:7

Step-by-step explanation:

since 72% of the school are boys and number of boys is 1800

means that :

72% * x = 1800

NB : is the number of students in the school

x = 1800/72%

x = 1800/0.72

x = 2500

total number of students is  2500

the number of girls in the school

2500 - 1800

= 700 girls

1800 : 700

can divide by 100

18 : 7

t pounds = 3.5 (or just t = 3.5c)

Step-by-step explanation:

2 pounds of tomatos for 7$ means that one pound of tomatos for 3.5$. Therefore, t pounds = 3.5 c

The equation which represents the sales of tomatoes will be ( t = 3.5c).

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

2 pounds of tomatoes for 7$ means that one pound of tomatoes for 3.5$. Therefore, t pounds = 3.5 c
