You are least likely to choose white. Bc there are only 4 of those.
A = ab ( the area of rectangle )
a b = 192
a b r² = 363
192 r² = 363
r = √363 / 192 = √121/64
r = 11/8
The similarity ratio of the two rectangles is 11/8.
Answer: B
Step-by-step explanation:
Answer:
Simplifying
x + 5 = 9x2 + x + 1
Reorder the terms:
5 + x = 9x2 + x + 1
Reorder the terms:
5 + x = 1 + x + 9x2
Add '-1x' to each side of the equation.
5 + x + -1x = 1 + x + -1x + 9x2
Combine like terms: x + -1x = 0
5 + 0 = 1 + x + -1x + 9x2
5 = 1 + x + -1x + 9x2
Combine like terms: x + -1x = 0
5 = 1 + 0 + 9x2
5 = 1 + 9x2
Solving
5 = 1 + 9x2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9x2' to each side of the equation.
5 + -9x2 = 1 + 9x2 + -9x2
Combine like terms: 9x2 + -9x2 = 0
5 + -9x2 = 1 + 0
5 + -9x2 = 1
Add '-5' to each side of the equation.
5 + -5 + -9x2 = 1 + -5
Combine like terms: 5 + -5 = 0
0 + -9x2 = 1 + -5
-9x2 = 1 + -5
Combine like terms: 1 + -5 = -4
-9x2 = -4
Divide each side by '-9'.
x2 = 0.4444444444
Simplifying
x2 = 0.4444444444
Take the square root of each side:
x = {-0.666666667, 0.666666667}

Answer: y=1/2x-1
Step-by-step explanation:
To find the equation of the line that passes through the points, we need to find out slope, m.
We plug our points into this formula to find slope.
Our slope is 1/2. To find our y-intercept, b, we would plug any point into the equation for slope-intercept form.
y=mx+b
y=1/2x+b
1=1/2(4)+b
1=2+b
b=-1
Now that we know b, our equation is y=1/2x-1.
