Symmetry means that if you split it in half, the two sides would be equal. For example, the letter X is symmetrical.

What is the math term for you taking parentheses away?

TEA [102]

You might be thinking of "distribution" or "distributive property"

Example:

2(3x+5) = 2*3x+2*5 = 6x+10

I multiplied the outer 2 by each term inside (3x and 5)

The braking distance, D, of a car is directly proportional to the square of its speed, v. When d=5, v=10

Ivenika [448]

Answer:

Step-by-step explanation:

d is directly proportional to the square of a speed v

d = av²

5 = a•10²

5 = 100a

a = 0.05

d = 0.05v²

d = 0.05•70²

d = 0.05•4900

d = 245

If the data is skewed to the left, the mean of this data is?

hodyreva [135]

Answer: substancially lower / more to the left

If the data is skewed to the left the mean will be moved more to the left so it will decrease. The mean is greatly changed by the skew of the data

Answer:

$\large\boxed{C.\ y=2+x^4}$

Step-by-step explanation:

The slope-intercept form of an equation of linear function:

$y=mx+b$

<em>m</em> - slope

<em>b</em> - y-intercept

============================

$A.\\\\9y+3=0\qquad\text{subtract 3 from both sides}\\\\9y=-3\qquad\text{divide both sides by 9}\\\\y=-\dfrac{3}{9}\\\\y=-\dfrac{1}{3}\to m=0,\ b=-\dfrac{1}{3}$

$B.\\\\y-4x=1\qquad\text{add}\ 4x\ \text{to both sides}\\\\y=4x+1\to m=4,\ b=1$

$C.\\\\y=2+x^4\qquad\text{nonlinear, because}\ x\ \text{is in fourth power}$

$D.\\\\x-2y=7\qquad\text{subtract}\ x\ \text{from both sides}\\\\-2y=-x+7\qquad\text{divide both sides by (-2)}\\\\y=\dfrac{1}{2}x-\dfrac{7}{2}\to m=\dfrac{1}{2},\ b=-\dfrac{7}{2}$

$E.\\\\\dfrac{x}{y}+1=2\qquad\text{subtract 1 from both sides}\\\\\dfrac{x}{y}=1\to y=x\to m=1,\ b=0$
