Answer:

x = 5

Step-by-step explanation:

If x + 5 = 10, then x would have to be 5 because 5 + 5 = 10.

The way you would solve this would be:

x + 5 = 10

subtract 5 from both sides of the equation

x + 5 - 5 = 10 - 5

simplify:

x = 5

Graph a triangle (STU) and reflect it over the y-axis to create triangle ST'U'.
lukranit [14]

The x-coordinates of \triangle S'T'U' will be the negation of the x-coordinates of \triangle STU

The line segment from S to the y-axis equals the line segment from S' to the y-axis. Similarly, the line segment from T to the y-axis equals the line segment from T' to the y-axis

See attachment for \triangle STU and \triangle S'T'U'

In order to solve this question, I will make the following assumptions.

Assume that the coordinates of \triangle STU are

S = (4,5)      

T = (5,9)

U=(3,8)

Refer to attachment for illustrations

<u>(1) Reflect </u>\triangle STU<u> over y-axis and describe the transformation</u>

To reflect \triangle STU across the y-axis, the following rule must be followed

(x,y) \to (-x,y)

This means that:

S = (4,5) \to S' = (-4,5)

T = (5,9) \to T' = (-5,9)

U=(3,8) \to U'=(-3,8)

<u>The description of the </u><u>transformation </u><u>is as follows:</u>

Notice that the signs of the x-coordinates \triangle STU and \triangle S'T'U' of both triangles are different.

In other words, if the x-coordinate of one is positive, then the other will have a negative x-coordinate; and vice versa.

<u>(2) Compare the segments and the line of reflection</u>

To reflect across the y-axis means that the reflecting line is the y-axis, itself.

The distance between a point to the y-axis is the absolute value of the x-coordinate.

So, the distance between S and the y-axis is:

S = |4| = 4

The distance between S' and the y-axis is:

S' = |-4| = 4

We can conclude that the two line segments are equal.

This is the same for other point T and T' because of the formula used above.

<u>From T and T' to the y-axis is:</u>

T =|5| =5

T' =|-5| =5

Solve 3x^2 + 4x - 12 = 0
Andrei [34K]

Answer: x^2 = 2

Step-by-step explanation: 3x^2 + 4x=12

                                             6x^2=12

                                             x^2= 12/6

                                             x^2= 2

Andy, who loves to cook, makes apple cobbler for his family. The recipe (serves 6) calls for 5 3/4 pounds of apples, 6 3/4 cups
ch4aika [34]
Apples : 5 3/4 * 2 1/2 = 23/4 * 5/2 = 115/8 = 14 3/8 lbs

flour : 6 3/4 * 2 1/2 = 27/4 * 5/2 = 135/8 = 16 7/8 cups

margarine : 1/8 * 2 1/2 = 1/8 * 5/2 = 5/16 cups

sugar : 3 5/8 * 2 1/2 = 29/8 * 5/2 = 145/16 = 9 1/16 cups

cinnamon : 2 * 2 1/2 = 2/1 * 5/2 = 10/2 = 5 teaspoons
