<span>Simplifying 7b + -4 + 3b + 11 + -1b = 0

Reorder the terms: -4 + 11 + 7b + 3b + -1b = 0

Combine like terms: -4 + 11 = 7 7 + 7b + 3b + -1b = 0

Combine like terms: 7b + 3b = 10b 7 + 10b + -1b = 0

Combine like terms: 10b + -1b = 9b 7 + 9b = 0

Solving 7 + 9b = 0

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '-7' to each side of the equation.
7 + -7 + 9b = 0 + -7

Combine like terms: 7 + -7 = 0 0 + 9b = 0 + -7 9b = 0 + -7

Combine like terms: 0 + -7 = -7 9b = -7

Divide each side by '9'. b = -0.7777777778 Simplifying b = -0.7777777778</span>

Identify a sequence of transformations that maps triangle ABC onto triangle A"B"C" in the image below.

Murljashka [212]

Answer:

The correct option is B.

Step-by-step explanation:

It is given that triangle A"B"C" is the image of triangle ABC after transformation.

From the given figure it is noticed that the point C lies on positive y-axis and point C" lies on negative x-axis.

It means the figure is rotated either counterclockwise 90° or clockwise 270°. The rotation rule is

$(x,y)\rightarrow (-y,x)$

The corresponding sides of image A"B"C" are smaller than the preimage ABC.

$k=\frac{A"B"}{AB}=\frac{3}{6}=\frac{1}{2}$

Since k<0, therefore the transformation shows the reduction. The dilation rule is

$(x,y)\rightarrow (-\frac{1}{2}y,\frac{1}{2}x)$

$A(-3,0)\rightarrow (-\frac{1}{2}(0),\frac{1}{2}(-3))\rightarrow (0,-1.5)$

$B(3,0)\rightarrow (-\frac{1}{2}(0),\frac{1}{2}(3))\rightarrow (0,1.5)$

$C(0,5.2)\rightarrow (-\frac{1}{2}(5.2),\frac{1}{2}(0))\rightarrow (-2.6,0)$

Option B is correct.

A store has a $120 dress. Then there is a 200% increase in the price of the dress. What is the final price of the dress?

LenKa [72]

Multiply 120 by 200 percent and you would get 240, then you would add 240 and 120 to get 360.

A glacier in Alaska moves about 29.9 meters a day. About how much farther will it move in 1000 days then it will move in 100 day

Xelga [282]

If it moves 29.9 meters a day, then we need to find the total amount of days:

1000 days + 100 days = 1100 days

Since it moves 29.9m per day, we can write:

29.9m x 1100 which equals 32 890m

So it moved 32 890m
