Answer:

y = 2x - 4

Step-by-step explanation:

Using the equation y = mx + b we can write an equation, where m is the slope and b is the y-intercept. Plug in for the variables and you will get your answer.

y = 2x + (-4)

y = 2x - 4

Hope this helps.

Answer:

y=2x-4

Step-by-step explanation:

The equation of a line in slope-intercept form is:

y=mx+b

Where "m" is the slope, "b" is the y-intercept, and "x" and "y" are the x and y coordinates.

We are given the slope and the y-intercept therefore the equation would be:

y=2x+(-4)

y=2x-4

Answer:

They made 4 forks and 6 spoons last April.

Step-by-step explanation:

Let forks they made in april be x and spoons be y.

To make 1 fork we need $2

To make 1 spoon we need $1

They sell 1 fork for $6 and 1 spoon for the same amount So,

now,

Turning it into two equations :-

(x = number of forks and y = number of spoons)

2x + 1y = 14

6x + 6y = 60

Now,

2x + y = 14

y = 14 - 2x

Now,

6x + 6y = 60

or, 6x + 6(14-2x) = 60

or, 6x + 84 - 12x = 60

or, -6x = -24

so, x = 4

Now,

y = 14 - 2x

or, y = 14 - 2×4

or, y = 14-8

so, y = 6

Answer:

1 or 2/2

Step-by-step explanation:

4 divided by 2 is 2 and 18 divided by 9 is 2 so 2/2=1

There several forms of the equation of a line. Most of us learn the three most common forms, which are (in order from most common to least common):

1. The slope intercept form: y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line meets the y-axis)

2. The point-slope form: y - y1 = m (x - x1), where m is the slope of the line and (x1, y1) are the coordinates of a point on this line.

3. The Standard Form: Ax + By = C, where A, B, and C are real numbers, and A and B are not both zero (A & B cannot be zero simultaneously).

So, now that we know the three forms, we try to figure out which one of the three is easiest to find (unless the question asks to find a specific form), given the information.

Here, we are given the point (4, 12) and the value of the y-intercept -2. This means we are given two points, (4, 12) and (0, -2).

Using this information, we can first find the slope, using the formula: m = (y2 - y1)/(x2 - x1).

Here, m = (12 -(-2))/(4-0)  = 14/4 = 7/2

Now that we have the slope and the y-intercept, we can find the equation of this line in slope-intercept form:

y = (7/2)x - 2

Have a great day <3

Answer:

x = 20

Step-by-step explanation:

The 3 angles lie on a straight line and sum to 180° , that is

3x + 80 + 2x = 180

5x + 80 = 180 ( subtract 80 from both sides )

5x = 100 ( divide both sides by 5 )

x = 20

Answer:

Here,3x°+80°+2x=180° [Angles on a line]

or,3x°+2x°+80°=180°

or,5x°+80°=180°

or,5x°=180°-80°

or,5x°=100°

or,x°=100/5

Therefore,x°=20°

Answer:

2a)  -2

b) 8

Step-by-step explanation:

Equation of a parabola in vertex form

f(x) = a(x - h)² + k

where (h, k) is the vertex and the axis of symmetry is x = h

2 a)

Using the equation of a parabola in vertex form, a parabola with vertex (2, -6):  

f(x) = a(x - 2)² - 6

If one of the x-axis intercepts is 6, then

                 f(6) = 0

⇒ a(6 - 2)² - 6 = 0

⇒         16a - 6 = 0

⇒              16a = 6

⇒                  a = 6/16 = 3/8

So f(x) = 3/8(x - 2)² - 6

To find the other intercept, set f(x) = 0 and solve for x:

                    f(x) = 0

⇒ 3/8(x - 2)² - 6 = 0

⇒      3/8(x - 2)² = 6

⇒           (x - 2)² = 16

⇒              x - 2 = ±4

⇒                   x = 6,  -2

Therefore, the other x-axis intercept is -2

b)

Using the equation of a parabola in vertex form, a parabola with vertex (2, -6):  

f(x) = a(x - 2)² - 6

If one of the x-axis intercepts is -4, then

                 f(-4) = 0

⇒ a(-4 - 2)² - 6 = 0

⇒         36a - 6 = 0

⇒              36a = 6

⇒                  a = 6/36 = 1/6

So f(x) = 1/6(x - 2)² - 6

To find the other intercept, set f(x) = 0 and solve for x:

                    f(x) = 0

⇒  1/6(x - 2)² - 6 = 0

⇒       1/6(x - 2)² = 6

⇒           (x - 2)² = 36

⇒              x - 2 = ±6

⇒                   x = 8,  -4

Therefore, the other x-axis intercept is 8

Answer:

1 = 2 units

2 = 4 units

P = 36 units

A = 20 units²

Step-by-step explanation:

1. PART A:

Missing length 1 = 14 - 12 = 2 units

Missing length 2 = 1 + 3 = 4 units

PART B

The perimeter is the distance all the way around the outside of a 2D shape. To work out the perimeter, add up the lengths of all the sides

Perimeter = 1 + 12 + 3 + 2 + 4 + 14 = 36 units

PART C

Area of a rectangle = width x height

Separate the shape into 2 rectangles (so draw a line down from the internal corner of the L shape).

Total area = 1 x 14 + 2 x 3 = 14 + 6 = 20 units²

Answer: Choice B is correct

Explanation:

I think it's beneficial to look at [tex](a+b)^n[/tex] for small values of n such as n = 1, n = 2, n = 3, etc.

and so on.

In general, the expansion of [tex](a+b)^n[/tex] will have n+1 terms.

When dealing with [tex](x-8y)^{10}[/tex], we have n = 10 lead to n+1 = 10+1 = 11 terms.

The coefficients of each binomial expansion can be found in Pascal's Triangle. Or you can use the nCr combination formula.

68% falls within 83.4 ± 13.3 = (70.1, 96.7)

95% falls within 83.4 ± 2 * 13.3 = (56.8, 110)

99.7% falls within 83.4 ± 3 * 13.3 = (43.5, 123.3)

Empirical rule states that for a normal distribution, 68% falls within one standard deviation from the mean, 95% falls within two standard deviation from the mean and 99.7% falls within three standard deviation from the mean.

Given that mean = 83.4, standard deviation = 13.3, hence:

68% falls within 83.4 ± 13.3 = (70.1, 96.7)

95% falls within 83.4 ± 2 * 13.3 = (56.8, 110)

99.7% falls within 83.4 ± 3 * 13.3 = (43.5, 123.3)

  (a)  10x^2−x−21

Step-by-step explanation:

The area of a rectangle is given by the formula ...

  A = LW . . . . . where L is the length, and W is the width

__

The area of the given rectangle will be ...

  A = (2x -3)(5x +7)

This product is simplified using the distributive property to eliminate parentheses. Then like terms are combined.

  A = 2x(5x +7) -3(5x +7)

  = (2x)(5x) +(2x)(7) -3(5x) -3(7)

  = 10x^2 +14x -15x -21

  A = 10x^2 -x -21

The expression 10x^2 -x -21 represents the area of the rectangle in square inches.

Step-by-step explanation:

took the K12 test

In given figure, angle R is obtuse angle Therefore, option B is the correct answer.

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

An obtuse angle is a type of angle that is always larger than 90° but less than 180°.

In the given figure, angle R is greater than 90° but less than 180°.

So, angle R is obtuse angle

Therefore, option B is the correct answer.
