Answer:

Sam is correct

Step-by-step explanation:

The third side is the one with greatest length. To make a triangle the other two lengths have to be greater than the greatest one when combined.

Hope this Helps.

Answer:

-1 and - 6

Step-by-step explanation:

Since you cannot have the denominator 0..... - 1 and - 6

make the denominator 0. Therefore they are excluded values

Attempted but just couldnt understand (25Points)

Rashid [163]

Answer:

a) Function:Yes

b) Domain: $-5\:$

c) Range: $-5\le y\le 3$

Step-by-step explanation:

The given graph passes vertical line test hence it is a function

The given function has x-intercepts at $x=-4.5, x=-1,x=3.5$

We can therefore write this function in factored form as $y=a(2x+9)(x+1)(2x-7)$

There is a y-intercept at (0,-2)

$-2=a(2*0+9)(0+1)(2*0-7)$

$-2=-63a$

$a=\frac{2}{63}$

The required function is

$y=\frac{2}{63}(2x+9)(x+1)(2x-7)$

b) The domain refers to all values of x for which this function is defined.

The domain from the graph is $-5\:$ because there are holes at the end of the graph.

c) The range is the value of y for which x is defined or the graph exists.

From the graph the range is $-5\le y\le 3$

In math i have to find the percent cost of 6 prices but i'm not sure how to.

tresset_1 [31]

My answer got deleted for some reason, so here we go again. To convert a number to a percent, you multiply the number by 100. So if you had the number 2.4, you would multiply it by 100 to get 240%. After multiplying it by 100, simply add a percent sign, and you're done!

Here is a system of equations. (y=x-6 y=-x-2 Graph the system. Then write its solution. Note that you can also answer "No soluti

sladkih [1.3K]

Answer:

Example system with no solution

We're asked to find the number of solutions to this system of equations:

\begin{aligned} y &= -3x+9\\\\ y &= -3x-7 \end{aligned}

=−3x+9

=−3x−7

Without graphing these equations, we can observe that they both have a slope of -3−3minus, 3. This means that the lines must be parallel. And since the yyy-intercepts are different, we know the lines are not on top of each other.

There is no solution to this system of equations.

Example system with infinite solutions

We're asked to find the number of solutions to this system of equations:

\begin{aligned} -6x+4y &= 2\\\\ 3x-2y &= -1 \end{aligned}

−6x+4y

3x−2y

=−1

Interestingly, if we multiply the second equation by -2−2minus, 2, we get the first equation:

\begin{aligned} 3x-2y &= -1\\\\ \blueD{-2}(3x-2y)&=\blueD{-2}(-1)\\\\ -6x+4y &= 2 \end{aligned}

3x−2y

−2(3x−2y)

−6x+4y

=−1

=−2(−1)

In other words, the equations are equivalent and share the same graph. Any solution that works for one equation will also work for the other equation, so there are infinite solutions to the system.
