Directions

You have to do this by following directions.

1, Go one circle to your right. Make it the top circle.

2, Drop a perpendicular from the circle you've just been directed to.

3. Draw until you hit the center of the circle below the circle you started your line from. You should get a square.

Find the area of the square.

Each side of the square is 2 feet. You get that because the side of the square = 2 radii -- one radii from the two circles in the center.

Area Square = s^2

Area Square = 2 * 2

Area Square = 4

Find the are of the circles

The 4 central circles that are touching (2 to the left and 2 to the right)  are each are 1/4 of a full circle. 4 * 1/4 circle Area = 1 full circle.

Area = pi * r^2 = 3.14 * 1^2 = 3.14

Find the area of the star

Area of the star = area of square - area of circle.

Area of the star = 4 - 3.14

Area of the star = .86 sqr feet

Answer:

six plastic bricks and four wooden blocks

Step-by-step explanation:

plastic bricks=10

wooden blocks:5

lets make plastic x and wooden y

if we made an eight pound mixture of only plastic bricks, that would get us to 80, but would not be enough weight. if we substitute one x pound for two y, we would have 9 pounds and $80. if we substitute this again, we have ten pounds and $80. we added four wooden blocks, and we took two away from the 8 plastic we had, so that is 6 plastic. so we have 6x and 4y, using the variables I assigned for the blocks above.

Answer:

1) The slope-intercept and standard forms are [tex]y = -5\cdot x + 1[/tex] and [tex]5\cdot x +y = 1[/tex], respectively.

2) The slope-intercept form of the line is [tex]y = \frac{5}{2}\cdot x -\frac{9}{2}[/tex]. The standard form of the line is [tex]-5\cdot x +2\cdot y = -9[/tex].

3) The slope-intercept form of the line is [tex]y = \frac{5}{2}\cdot x + 5[/tex]. The standard form of the line is [tex]-5\cdot x +2\cdot y = 10[/tex].

4) The slope-intercept and standard forms of the family of lines are [tex]y = \frac{2}{7}\cdot x -\frac{c}{7}[/tex] and [tex]2\cdot x -7\cdot y = c[/tex], [tex]\forall \,c \in \mathbb{R}[/tex], respectively.

5) The slope-intercept form of the line is [tex]y = 2\cdot x-7[/tex]. The standard form of the line is [tex]-2\cdot x +y = -7[/tex].

Step-by-step explanation:

From Analytical Geometry we know that the slope-intercept form of the line is represented by:

[tex]y = m\cdot x + b[/tex] (1)

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]m[/tex] - Slope, dimensionless.

[tex]b[/tex] - y-Intercept, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

In addition, the standard form of the line is represented by the following model:

[tex]a\cdot x + b \cdot y = c[/tex] (2)

Where [tex]a[/tex], [tex]b[/tex] are constant coefficients, dimensionless.

Now we process to resolve each problem:

1) If we know that  [tex]m = -5[/tex] and [tex]b = 1[/tex], then we know that the slope-intercept form of the line is:

[tex]y = -5\cdot x + 1[/tex] (3)

And the standard form is found after some algebraic handling:

[tex]5\cdot x +y = 1[/tex] (4)

The slope-intercept and standard forms are [tex]y = -5\cdot x + 1[/tex] and [tex]5\cdot x +y = 1[/tex], respectively.

2) From Geometry we know that a line can be formed by two distinct points on a plane. If we know that [tex](x_{1},y_{1})=(1,-2)[/tex] and [tex](x_{2},y_{2}) = (3,3)[/tex], then we construct the following system of linear equations:

[tex]m+b= -2[/tex] (5)

[tex]3\cdot m +b = 3[/tex] (6)

The solution of the system is:

[tex]m = \frac{5}{2}[/tex], [tex]b = -\frac{9}{2}[/tex]

The slope-intercept form of the line is [tex]y = \frac{5}{2}\cdot x -\frac{9}{2}[/tex].

And the standard form is found after some algebraic handling:

[tex]-\frac{5}{2}\cdot x +y = -\frac{9}{2}[/tex]

[tex]-5\cdot x +2\cdot y = -9[/tex] (7)

The standard form of the line is [tex]-5\cdot x +2\cdot y = -9[/tex].

3) From Geometry we know that a line can be formed by two distinct points on a plane. If we know that [tex](x_{1},y_{1})=(-2,0)[/tex] and [tex](x_{2},y_{2}) = (0,5)[/tex], then we construct the following system of linear equations:

[tex]-2\cdot m +b = 0[/tex] (8)

[tex]b = 5[/tex] (9)

The solution of the system is:

[tex]m =\frac{5}{2}[/tex], [tex]b = 5[/tex]

The slope-intercept form of the line is [tex]y = \frac{5}{2}\cdot x + 5[/tex].

And the standard form is found after some algebraic handling:

[tex]-\frac{5}{2}\cdot x+y =5[/tex]

[tex]-5\cdot x +2\cdot y = 10[/tex] (10)

The standard form of the line is [tex]-5\cdot x +2\cdot y = 10[/tex].

4) If we know that [tex]a = 2[/tex] and [tex]b = -7[/tex], then the standard form of the family of lines is:

[tex]2\cdot x -7\cdot y = c[/tex], [tex]\forall \,c \in \mathbb{R}[/tex]

And the standard form is found after some algebraic handling:

[tex]-7\cdot y = -2\cdot x +c[/tex]

[tex]y = \frac{2}{7}\cdot x -\frac{c}{7}[/tex], [tex]\forall \,c\in\mathbb{R}[/tex] (11)

The slope-intercept and standard forms of the family of lines are [tex]y = \frac{2}{7}\cdot x -\frac{c}{7}[/tex] and [tex]2\cdot x -7\cdot y = c[/tex], [tex]\forall \,c \in \mathbb{R}[/tex], respectively.

5) If we know that [tex](x,y) = (3,-1)[/tex] and [tex]m = 2[/tex], then the y-intercept of the line is:

[tex]3\cdot 2 + b = -1[/tex]

[tex]b = -7[/tex]

Then, the slope-intercept form of the line is [tex]y = 2\cdot x-7[/tex].

And the standard form is found after some algebraic handling:

[tex]-2\cdot x +y = -7[/tex] (12)

The standard form of the line is [tex]-2\cdot x +y = -7[/tex].

6x-6+6x-x-1=452+2x

9x = 459

x=51

The numbers are 50, 51, and 52.

Step-by-step explanation:

[tex] f(x) \: = \: \frac{4}{5} - \frac{5}{x + 1} [/tex]

[tex]f(x) \: \: = \: \: \frac{(4)(x + 1) - 5(5)}{5x + 5} [/tex]

[tex]f(x) \: \: = \: \: \frac{4x + 4 - 25}{5x + 5} [/tex]

[tex]f(x) \: \: = \: \: \frac{4x - 21}{5x + 5} [/tex]

f(x) = g(x)

[tex] \frac{4x - 21}{5x + 5} = \frac{2}{5x + 5} [/tex]

4x - 21 = 2

x = (21 + 2)/4

Answer:x =24

Step-by-step explanation: If we reverse that we will get x= 32x3/4 which is 24

Answer:

x = -24

Step-by-step explanation:

(-4/3)x -6 =26

Add 6 to both sides:

(-4/3)x = 32

(-4/3) = -1.33333333

divide both sides by -1.33333333

x = -24

Substitute:

(-4/3)(-24) -6 =26

32 - 6 = 26

26 = 26

x = -24

Answer:

Y=3x+12 (its the first option)

Step-by-step explanation:

I did the assignment.

The equation of the line parallel to (3x - y = 7) passes through the point (-5, -3) is y = 3x + 2 and this can be determined by using the one-point slope form.

Given :

The line passes through the point (-5, -3) and is parallel to the line (y - 3x = -7).

The following steps can be used in order to determine the equation of a line that passes through the point (-5, -3) and is parallel to the line (y - 3x = -7):

Step 1 - The one-point form of a line is used in order to determine the equation of a line that passes through the point (-5, -3) and is parallel to the line (y - 3x = -7).

Step 2 - The one-point form is given below:

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

Step 3 - According to the given data, the line is parallel to the line (y = 3x - 7). So, the slope of the line is 3.

Step 4 - Now, substitute the values of slope and the point in the above expression.

[tex](y+3) = 3 (x+5)[/tex]

y = 3x + 2

The probability that the bag has buttons is 0.38.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes.

Given that, a company makes 130 bags.

Here, the number of favorable outcomes = 49 and the total number of outcomes =130

Now, probability of an event = 49/130
