Answer:

5

Step-by-step explanation:

Convert the equation into standard form and look for the value without a variable.

[tex]3x^2+7-2(4x+1)\\3x^2+7-8x-2\\3x^2-8x+7-2\\3x^2-8x+5[/tex]

9 is the constant

Answer:

(9,20)

Step-by-step explanation:

9 and 20 together... (9,20)

Answer:

4x - 12y = -1

Step-by-step explanation:

Standard form Ax +By = C

12y = 4x + 1

0 = 4x - 12y +1            Substract 12y from both sides

-1 = 4x - 12y  as  4x - 12y = -1      Substract -1 from both sides

These 4 consecutive multiples of 3 are of the form

3N, 3 (N + 1), 3 (N + 2), 3 (N + 3)

The given constraint is captured in the equation

5 (3N + 3 (N + 3)) = 13 (3 (N + 2)) - 6

Solve for N :

5 (3N + 3N + 9) = 13 (3N + 6) - 6

5 (6N + 9) = 13 (3N + 6) - 6

30N + 45 = 39N + 78 - 6

30N + 45 = 39N + 72

30N - 39N = 72 - 45

-9N = 27

N = 27/(-9)

N = -3

Then the 5 consecutive multiples of 3 are

-9, -6, -3, 0

Answer:

X=-33

Step-by-step explanation:

Answer:

x= -33

Step-by-step explanation:

Subtract 9 from both sides:

2/3x+9-9=-13-9

Simplify the arithmetic:

2/3 · x =-13-9

Simplify the arithmetic:

2/3 · x = -22

Multiply both sides by inverse fraction 3/2:

2/3x ·3/2= -22 ·3/2

Group like terms:

 2/3 ·3/2x= -22 ·3/2

Simplify the fraction:

x=-22 · 2/3

Multiply the fractions:

x= -22·2/3 ÷2

Simplify the arithmetic:

x = -33

Answer: 71

Step-by-step explanation:

An isosceles triangle has two equal angles. The sum of a triangle is 180 degrees so the answer of x is 71 degrees.

Answer:

[tex]\underline{\boxed{\sf x=74^o}}[/tex]

Step-by-step explanation:

The given triangle is in isosceles triangle because it has two congruent sides. Angles across from the congruent sides are also congruen, so the angle without a label measures x.

(3 angles in a triangle add up to 180°).

Equation:- [tex]\sf x^o+x^o+32^o=180^o[/tex]

Let's solve for x:-

[tex]\sf x+x+32=180[/tex]

[tex]\sf 2x+32=180[/tex] (Simplify)

[tex]\sf 2x+32-32=180-32[/tex] (Subtract)

[tex]\sf 2x=148[/tex]

[tex]\sf \dfrac{2x}{2} =\dfrac{148}{2}[/tex] (Divide)

[tex]\sf x=74^o[/tex]

Answer:

x = 4

Step-by-step explanation:

3x = x + 8

Subtract x from both sides

3x -x = 8

2x = 8

Divide both sides by 2

x = 8/2

x = 4

1st step is to copy a segment and an angle , 2nd step is to set the width of the compass to the length of segment. and last step to draw a perpendicular line.

What is geometry ?

Geometry is the branch of mathematics focused on the relationships and characteristics of solids, surfaces, solids, and other such objects.

Given, we must describe the first stage , which will be the process of copying a line segment, which ensures that the new line segment is the same length as the original line segment. An angle and a segment must be copied as a first step. The picture gives a description of the copying construction.

The width of the compass must then be adjusted to the segment length. The new angle will now be consistent with the original angle. This is the next step.

Making a perpendicular line is the next step. Here, it is demonstrated how to draw a line through a point that is perpendicular to the given line.

Therefore , 1st step is to copy a segment and an angle , 2nd step is to set the width of the compass to the length of segment. and last step to draw a perpendicular line.

Answer:

5 is the slope

Step-by-step explanation:

Because the equation is y=mx+b

m=slope and b=y intercept

Answer:

The slope of the line y = 5x + 4 is 5.

Step-by-step explanation:

In the equation y = mx + b,

m represents the slope

b represents the y-intercept.

In the equation y = 5x + 4, 5 takes place of m. Since this is the case, m = 5, or 5 is the slope.

Width: 15 cm

Area: 150 cm squared

Step-by-step explanation:

I did 10 + 10 to get the total of the two sides of the rectangle.

I subtracted 20 from 50 to get what the two widths are supposed to add up to.

The answer was 30 so I divided 30 by 2 to get what one width equals.

The width equals 15.

To get the area of a rectangle you have to multiply the length by the width which would be 150 cm squared.

Step-by-step explanation: the width is 15cm

Chronological

Step-by-step explanation:

These texts organize events in the order they happened. This structure is common in current events, history and in works of fiction or memoir. Key words include time markers like “first,” “next,” “then” and “finally.”

This type of prediction is extrapolation

Give the equation for the line of best fit expressed as:

y = -3x + 21

If x = 10, substitute the value of x into the function to get y

y = -3(10) + 21

y = -30 + 21

y = -9

This type of prediction is extrapolation.  Extrapolation has to do with estimating a value given that a particular variable is given.

The fraction of the labelled angle is: 2/3 of one semicircle.

In radians, it is: 2.0944 rad.

Recall:

One semicircle = 3.1416 radian

One semicircle = 180 degrees

Thus, 120 degrees of a semicircle as a fraction would be:

Therefore, 120 degrees equals 2/3 semicircle.

Convert to radians:

One semicircle = 3.1416 radian

2/3 semicircle = x

[tex]x = 3.1416 \times \frac{2}{3} \\\\\mathbf{x = 2.0944 $ rad}[/tex]
