Answer:

A

Step-by-step explanation:

This would be directly conflicting and would result in no answer as you would be saying that x could equal a number that would turn out the same if 2 were added to it and 3 were subtracted from it.

Answer:

A

Step-by-step explanation: Here's something that I learned. Same slope different y-intercept (no solution). Same slope and same y-intercept (Infinitely many solutions). Different slope and same y-intercept (one solution). Different slope and different y-intercept (one solution).

Answer:

look for the LCM of all the denominators, devide the denominators by the LCM and add the numerators( don't forget the signs ), then add and subtract your answers ( by this time the LCM becomes the denominator and the answer from th subtraction and addition of the numerators becomes the present numerator ), then reduce to lowest term the answer gotten

Answer:

y-4=3/2(x+4)

Step-by-step explanation:

If you plug the numbers into the equation (y-y1=m(x-x1)), you get y-4=3/2(x+4).

Answer: y=3/2x+13

Step-by-step explanation: y-4=3/2(x-(-6))

y-4=3/2x+9

y=3/2x+13

I got this : ) I hope it helped

The expression x³ + 2x represents the sum of the cube of a number and two times the number "x."

"the sum of the cube of a number and two times the number."

Let "x" represent the unknown number.

Express the given in algebra form as x³ + 2x.

To calculate the value of this expression for a specific value of "x," substitute the value of "x" into the expression.

Cube the number by raising it to the power of 3 (x³).

Multiply the number by 2 (2x).

Add the results

expression x³ + 2x represents the sum.

Step-by-step explanation:

25/100 x 79

= 19.75

= 79 - 19.75

= $59.25 (before tax)

7/100 x 59.25

= 414.75/100

= 4.15

= 59.25 + 4.15

= $63.4 (after adding tax)

First we have to take out the percentage of discount and minus it from the total cost . To find the discounted price with tax, we have to take out the percentage of the tax from the discounted amount and add it to the discounted amount to get the total cost.

Answer:

144.6°

Step-by-step explanation:

180-35.4

144.6°

Answer:

144.6

Step-by-step explanation:

Supplementary angles add to 180

Let x be the unknown angle

x + 35.4 = 180

Subtract 35.4 from each side

x = 180-35.4

x =144.6

Answer:

Step-by-step explanation:

Let the number of weeks = x

4*2.54 + 4x = growth for A

10*2.54 + 1*x= growth for B

So they will be the same when the 2 left sides are equated.

10.16 + 4x = 25.5 + x            Subtract 10.16 from both sides

4x =25.5-10.16 + x                Combine

4x = 15.34 + x                       Subtract x from both sides.

4x-x = 15.34

3x = 15.34                             Divide by 3

x = 15.34/3

x = 5.11

So the answer is just a little over 5 weeks.

Answer:

345.333333Step-by-step explanation:

Answer:

Step-by-step explanation:

(5x - 1) (5x - 1)

= [tex](5x - 1)^{2}[/tex]

Using laws of exponents,

[tex](a - b)^{2} = a^{2} - 2ab + b^{2}[/tex]

here, a = 5x, b = 1

so it becomes,

[tex]5x^{2}[/tex] - 2 × 5x × 1 + [tex]1^{2}[/tex]

[tex]25x^{2}[/tex] - 10x + 1

Answer:

Step-by-step explanation:

If there are 2 or more right angles in a triangle, it is impossible to connect without a fourth side, making it a square. There can only be 1 right angle in a triangle

Answer:

There can Only be 1 Right angle in a Triangle!

Step-by-step explanation:

Triangles have 180 degrees in total, If You had Two Right Angles, Then it would equal 180, since there is three angles,three sides and etc on a triangle that won't work. In a Triangle you could have 1 right angle and Two 45 degree angles to get your total of 180 degrees and a complete Triangle!!

Answer:

(6, -11), (-10, -7) and (-2, -11)

Step-by-step explanation:

Coordinates of a triangle are represented in the form of a matrix as,

[tex]\begin{bmatrix}x_1 & x_2 & x_3\\ y_1 & y_2 & y_3\end{bmatrix}[/tex]

If the given triangle is shifted by 1 unit left and 4 units down,

Translation of vertices in the matrix form will be,

[tex]\begin{bmatrix}x_1 & x_2 & x_3\\ y_1 & y_2 & y_3\end{bmatrix}+\begin{bmatrix}-1 & -1 & -1\\ -4 & -4 & -4\end{bmatrix}[/tex]

For a triangle having vertices (7, -7), (-9, -3) and (-1, -7) when shifted 1 units left and 4 units down will be,

[tex]\begin{bmatrix}7 & -9 & -1\\ -7 & -3 & -7\end{bmatrix}+\begin{bmatrix}-1 & -1 & -1\\ -4 & -4 & -4\end{bmatrix}[/tex]

= [tex]\begin{bmatrix}7-1 & -9-1 & -1-1\\ -7-4 & -3-4 & -7-4\end{bmatrix}[/tex]

= [tex]\begin{bmatrix}6 & -10 & -2\\ -11 & -7 & -11\end{bmatrix}[/tex]

Coordinates of the triangle after the translation will be,

(6, -11), (-10, -7) and (-2, -11)
