Identity property because it doesn’t change the answer it’ll still be 4 if u multiply it by one

The concavity of a function is described by its

lesya [120]

The concavity of a function is described by its second derivative.

-The expression will not directly tell us whether the function is concave up or concave down and where it changes, though graphing the function may give us some sort of idea.

-The first derivative tells us the critical/important values (where there could be asymptotes), as well as where the function is increasing/decreasing.

-The second derivative tells us again the critical/important values, but also where the function is concave up/down. We find concavity in the same way we find increasing/decreasing using the first derivative.

-The third derivative, at least in my experience, has only been used to find acceleration of a function.

Hope this helps!! :)

If you are trying to figure out the total distance of them all then yes. if you are not no.

Can someone help me.me and my friends are at a loss

Ganezh [65]

From the number given is appears the rule is y = 2x + 1
This works for all three:
17 = 2(8) + 1
1 = 2(0) + 1
15 = 2(7)+1

Answer:

The only options which are having same solution as the given equation is A, B and D.

Explanation:

Given the equation: $\frac{3}{5}x+ \frac{2}{3} +x =\frac{1}{2}- \frac{1}{5}x$ ......[1]

Like terms are terms whose variables are the same.

In the given equation [1],

Combine like terms of variable x on LHS; we have

$\frac{3x+5x}{5}+ \frac{2}{3} =\frac{1}{2}- \frac{1}{5}x$

Simplify:

$\frac{8x}{5}+\frac{2}{3} =\frac{1}{2}- \frac{1}{5}x$

or we can write this as;

$\frac{8}{5}x +\frac{2}{3} =\frac{1}{2}- \frac{1}{5}x$ .

LCM(Least Common Multiple) to change each fraction to make their denominators the same as the least common denominator.

Taking LCM to both sides of an equation [1] as;

LCM of 3, 5 on LHS is 15 and LCM of 2 , 5 on RHS is 10;

$\frac{9x+10+15x}{15} = \frac{5-2x}{10}$

By cross multiplication we get;

$10 \cdot (9x+10+15x) = 15 \cdot (5-2x)$

Divide both side by 5 we get;

$2 \cdot (9x+10+15x) = 3 \cdot (5-2x)$

Using distributive property on both sides of an equation (i.e, $a\cdot (b+c) =a\cdot b+a\cdot c$ )

we have;

$18x+20+30x = 15-6x$ ......[2]

Additive Property of Equality states that allows one to add the same quantity to both sides of an equation.

Using additive property of equality:

Add 6x to both sides of an equation in [2];

$18x+20+30x+6x = 15-6x+6x$

Simplify;

$18x+20+30x+6x = 15$

Combine 18x and 6x we get;

$24x+20+30x= 15$ ......[3]

Subtraction Property of Equality states that allows one to subtract the same quantity to both sides of an equation.

Subtract 20 from both sides of an equation in [3] we get;

$24x+20+30x-20= 15-20$

Simplify:

$24x+30x= -5$

Therefore, from the given options only A, B and D have the same solution as $\frac{3}{5}x+ \frac{2}{3} +x =\frac{1}{2}- \frac{1}{5}x$
