Answer:

x = -1

Step-by-step explanation:

to find axis of symmetry, use the following equation:

x = -b/2a

in this problem, a = 3, b = 6, c = -12

x = -6/2(3)

x = -6/6

x = -1

Answer:

$4.20

2.50+1.70=4.20

Answer:

Jack= $4.20

Bobby=$4.20

Ted=$4.20

Step-by-step explanation: This is the answer because if you add up all the drinks the total they payed is $12.60 so you just divided that by how many people there are and get $4.20

Step-by-step explanation:

A composite figure is made up of simple geometric shapes. To find the area of a composite figure or other irregular-shaped figures, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure. Formula = a(a=lw+bh)

The scale of drawing is 1 inch : 27 inch

The scale factor is a measure for similar figures, who look the same but have different scales or measures. The scale factor states the scale by which a figure is bigger or smaller than the original figure.

Given that, the measurement of the tile = 27/4 inches

Side of the drawing = 1/4 inches

The scale of the drawing =

1/4 inch of drawing = 27/4 inch of tile

That means, 1 inch of the drawing = 27 inch of the tile

Therefore,

The scale of the drawing is 1 inch : 27 inch

Hence, option D is correct

Answer:

y = 60°

Step-by-step explanation:

The tangent- chord angle y is half the measure of its intercepted arc , then

y = [tex]\frac{1}{2}[/tex] × 120° = 60°

The value of y is 60 °

Given , the angle is 120°

Now apply the  tangent- chord angle theorem, " a chord meeting at the point of tangency is half the measure of the intercepted "

y = 1/2 × 120°

y = 1/2 × 120° = 60°

Therefore, the value of angle y is 60°.

Answer:

x = 5

Step-by-step explanation:

x² + (2x+2)² = (2x+3)²

x² + 4x² + 8x + 4 = 4x² + 12x + 9

x² - 4x - 5 = 0

(x - 5)(x + 1) = 0

x = -1  This can be discounted as the answer because you cannot have a negative length

answer: x = 5

Answer:

Option 4: y -x

Step-by-step explanation:

Option 1

Multiplying a positive and a negative number will result in a negative number.

For example, if x= -1 and y=5,

x(y)= -1(5)= -5 (a negative number)

Thus, option 1 is incorrect.

Option 2

In this option, we are essentially multiplying -1 to y, a positive number, before adding the result with x.

Since y is a positive number, -y is a negative number and hence x -y (when x is a negative number) will result in a negative number. Let's plug in values into x and y to check this.

For example, x= -2 and y=3.

x -y= -2 -3= -5

Option 2 is thus incorrect.

Option 3

Dividing a positive number with a negative number will result in a negative number.

For example: 6÷(-2)= -3

Option 3 is also incorrect.

Option 4

Subtracting a negative number from a positive number will result in a positive number.

For example: x= -1, y= 8

y -x= 8 -(-1)= 8 +1= 9

As seen from the example above, when the negative number is multiplied to negative 1, a positive sign results.

In summary, when a positive number is multiplied to a positive number, the resulting number is positive.

When a negative number is multiplied to a negative number, the resulting number is positive.

When a positive number is multiplied to a negative number, the resulting number is negative.

+(+)= +

-(-)= +

+(-)= -

This applies to division too.
