Answer:

C: The Same Line

Step-by-step explanation:

So to start we need to first know what makes lines parallel or perpendicular. Two parallel lines will have the same slope, but different y-intercepts because we know they never cross. Two perpendicular lines will have opposite-reciprocal slopes, because we know that they intersect at a right angle.

Then, we  need to know the slope-intercept form of an equation. The slope intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope of the line and [tex]b[/tex] is the y-intercept. We can see that neither equation is in this form, so we have to convert it.

Starting with the first, (I assume despite the typo) we have [tex]25y+10x= 200[/tex]

So we need to isolate the [tex]y[/tex] from everything else.

First, we'll subtract [tex]10x[/tex] from both sides of the equal sign to get [tex]25y=-10x+200[/tex]

Second, we'll divide both sides by [tex]25[/tex] to get [tex]y=-\frac{2}{5} x+8[/tex]

This means that [tex]-\frac{2}{5}[/tex] is the slope and [tex]8[/tex] is the y-intercept of the first line.

Now onto the second we have [tex]5y+2x=40[/tex] so we're going to follow the same steps to isolate [tex]y[/tex].

First, we'll subtract [tex]2x[/tex] from both sides to get [tex]5y=-2x+40[/tex]

Second, we'll divide both sides by [tex]5[/tex] to get [tex]y=-\frac{2}{5}x +8[/tex]

This means that [tex]-\frac{2}{5}[/tex] is the slope and [tex]8[/tex] is the y-intercept of the second line.

Since both of the lines have a slope [tex]-\frac{2}{5}[/tex] we know that they are parallel, so we need to check to check if they're the same by looking at the y-intercept. We can see that [tex]8[/tex] is the y-intercept of both lines, so they would be the same line.

Answer:

x^3+x×2

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.

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)

Answer:

hope it helps...

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:

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:

Step-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

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:

I cant see the thing just dont the answers down pls i can help just cant see the pic

Step-by-step explanation:

Answer: x= 60 degrees, y=25 degrees

ABC is equilateral so all angles are 60.

Therfore, we know that angle bcd must be 120 degrees.

Triangles are 180

120+35= 155

180-155= 25

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
