Answer:

13.8196601125

Step-by-step explanation:

i think i just did the math

slope intercept form:

y = mx + b

m = slope

b = y-intercept

the y-intercept is the place on the y-axis (vertical) where the line crosses. In this problem, the line crosses at (0,4), meaning the y-intercept is 4.

y = mx + 4

the slope is technically the rate of change (rise over run) bewteen points.

If you take the distance from point (-1,3) and (0,4) you get a slope of 1/1, or just 1

y = 1x +4

this could also be:

y = x + 4

(because the 1 is invisible but still there)

Answer:

3 x 2 − 2 x + 4 = 2 x 2 − 4

Step-by-step explanation:

Write the problem as a mathematical expression.

3 x 2 − 2 x + 4 = 2 x 2 − 4

Subtract  2 x 2 − 4  from both sides of the equation.

3 x 2 − 2 x + 4 − 2 x 2 − 4 = 0

Simplify each term.

Subtract  4  from  2 . 3 x 2 − 2 x + 4 − 2 x − 2 = 0

Rewrite the expression using the negative exponent rule  

b − n =1 b n . 3 x 2 − 2 x + 4 − 2 1 x 2 = 0

Combine  − 2  and  1 x 2 . 3 x 2 − 2 x + 4 + − 2 x 2 = 0

Move the negative in front of the fraction.

3 x 2 − 2 x + 4 − 2 x 2 = 0

Answer:

76 t-shirts

Step-by-step explanation:

The computation of the highest number of t-shirts purchased by the sports committee is as follows:

Since it is given that there is a fund of $2,790 among three committee that shared equally

That means

= $2,790 ÷ 3 committees

= $930 each

Now the sports committee wants to use its share for purchasing the t-shirt

And, if cost of each t-shirt is $12

So, the highest number of t-shirt purchase is

= $930 ÷ $12

= 77.5

= 76 t-shirts

Answer:

The equation of line shown in the graph is [tex]\mathbf{y=-\frac{1}{2}x -1}[/tex]

Step-by-step explanation:

We need to find equation of the line shown in graph.

The equation of line will be in slope-intercept form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

We need to find slope and y-intercept.

Finding y-intercept

Looking at the graph, we can find y-intercept when x =0, the value of y is known as y-intercept.

So, when x =0, y=-1

So, y-intercept is -1

Finding Slope

Now, for finding slope, consider 2 points on graph

(0,-1) and (-2,0)

Slope can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have [tex]x_1=0, y_1=-1, x_2=-2, y_2=0[/tex]

Putting values and finding slope:

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{0-(-1)}{-2-0} \\Slope=\frac{0+1}{-2-0} \\Slope=\frac{1}{-2} \\Slope=-\frac{1}{2}[/tex]

So, slope is [tex]m=-\frac{1}{2}[/tex]

Equation of line

Now, equation of line having slope [tex]m=-\frac{1}{2}[/tex] and y-intercept b = -1 is

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

So, equation of line shown in the graph is [tex]\mathbf{y=-\frac{1}{2}x -1}[/tex]

The solution is Option G.

The value of the equation A = ( 2/3 ) x 15% x $ 2000 = $ 200

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( 2/3 ) x 15% x 2000   be equation (1)

On simplifying the equation , we get

A = ( 2/3 ) x ( 15/100 ) x 2000

A = ( 2/3 ) x ( 15 ) x ( 20 )

On further simplification , we get

A = ( 2/3 ) x 300

A = 2 x 100

A = $ 200

Therefore , the value of A is $ 200

Hence , the equation is A = $ 200

Answer:

It is clear that both equations are identical. Hence, the solution to the system of equations would contain infinitely many solutions.

Step-by-step explanation:

Given the system of equations

y = -4x + 2

y = -4x + 2

It is clear that both equations are identical. We know that when the system of equations is identical, then the system of equations will have infinitely many solutions.

Hence the given system of equations would contain infinitely many solutions.

solving the system of equations

[tex]\begin{bmatrix}y=-4x+2\\ y=-4x+2\end{bmatrix}[/tex]

Substitute y = -4x+2

[tex]\begin{bmatrix}-4x+2=-4x+2\end{bmatrix}[/tex]

For y = -4x+2

Express y in terms of x

[tex]y=-4x+2[/tex]

Thus, the solution to the system of equations would be:

[tex]y=-4x+2,\:x=x[/tex]

It is clear that x = x is true no matter what. Hence, the solution to the system of equations would contain infinitely many solutions.

There are two unique triangles that can be formed two side lengths of 10 centimeters and one 40º angle.

Step-by-step explanation:

There are theoretically three unique triangles that can be formed with two side lengths of 10 centimeters and one 40º angle. We include a representation of possible triangles:

Case A - Law of Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]C = 40^{\circ}[/tex])

[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex] (1)

[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 40^{\circ}}[/tex]

[tex]c\approx 6.840\,cm[/tex]

Case B - Laws of Sine and Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]B = 40^{\circ}[/tex])

[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex] (2)

[tex]\sin A = \frac{a\cdot \sin B}{b}[/tex]

[tex]A = \sin^{-1}\left(\frac{a\cdot \sin B}{b} \right)[/tex]

[tex]A = \sin^{-1}\left[\frac{(10\,cm)\cdot (\sin 40^{\circ})}{10\,cm} \right][/tex]

[tex]A = 40^{\circ}[/tex]

[tex]C = 180^{\circ}-A-B[/tex]

[tex]C = 100^{\circ}[/tex]

[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex]

[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 100^{\circ}}[/tex]

[tex]c \approx 15.321\,cm[/tex]

Case C - Laws of Sine and Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]A = 40^{\circ}[/tex])

[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex]

[tex]\sin B = \frac{b\cdot \sin A}{a}[/tex]

[tex]B = \sin^{-1}\left(\frac{b\cdot \sin A}{a} \right)[/tex]

[tex]B = 40^{\circ}[/tex]

[tex]C = 180^{\circ}-A-B[/tex]

[tex]C = 100^{\circ}[/tex]

[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex]

[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 100^{\circ}}[/tex]

[tex]c \approx 15.321\,cm[/tex]

There are two unique triangles that can be formed two side lengths of 10 centimeters and one 40º angle.

Answer:

(x,y)--> (-x,-y)

Answer:

B

x = 22

Step-by-step explanation:

2x + 8 + 3x + 5 = 123    (external angle in a triangle = the two opposite angles)

5x = 123 - 13

5x = 110

x = 22

Answer: B

Step-by-step explanation:

By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.

(2x+8)+(3x+5)=123       [combine like terms]

5x+13=123                     [subtract both sides by 13]

5x=110                           [divide both sides by 5]

x=22

Now, we know that the answer is B.

Answer:

A rectangle is a quadrilateral in which all angles are right angles. A rectangle is a parallelogram, so its opposite sides are equal. The diagonals of a rectangle are equal and bisect each other.

Step-by-step explanation:

The quadratic equation is x² + (p - 5)x + 2q = 0.

By Vieta's Formula,

we have SOR = -b/a and POR = c/a.

=> (-3) + (6) = -(p - 5) and (-3)(6) = 2q.

=> 3 = 5 - p and -18 = 2q

Hence, p = 2 and q = -9.

Alternate Method:

We have (x + 3) and (x - 6) as factors of the quadratic equation x² + (p - 5)x + 2q = 0.

=> (x + 3)(x - 6) = x² - 3x - 18.

By Comparing Coefficients,

(p - 5) = -3 and 2q = 18.

Hence p = 2 and q = -9.
