Answer: Equivalent expression would be 9e-3.

Step-by-step explanation:

Since we have given that

$6e+3(e-1)$

As we need to simplify the above expression:

First we open the brackets :

$3(e-1)=3e-3$

Now, add it to 6e.

So, it becomes,

$6e+3e-3\\\\=9e-3$

Hence, equivalent expression would be 9e-3.

Which graph shows the solution set of the compound inequality 1.5 x minus 1 greater-than 6.5 or 7 x + 3 less-than negative 25?

saul85 [17]

Answer:

After solving the compound inequality $1.5x-1>6.5 \ or \ 7x+3$ we get $\mathbf{x>5 \ or \ x$

Option B is correct.

Step-by-step explanation:

We are given compound inequality: $1.5x-1>6.5 \ or \ 7x+3$

We will first solve the inequalities to find the value of x, then will draw the graph.

$1.5x-1>6.5 \ or \ 7x+36.5+1 \ or \ 7x+3-37.5 \ or \ 7x\frac{7.5}{1.5} \ or \ x5 \ or \ x< -4$

So, after solving the compound inequality $1.5x-1>6.5 \ or \ 7x+3$ we get $\mathbf{x>5 \ or \ x$

Now, the number line will be as shown in figure.

The description as given in options is:

A number line goes from negative 10 to positive 10. An open circle appears at negative 4 and positive 5. The number line is shaded from negative 4 toward negative 10. The number line is also shaded from positive 5 toward positive 10.

so, Option B is correct.

Which equation could be used to find the length of the hypotenuse ?

k0ka [10]

The pythagorean theorem is $leg^2+leg^2=hypotenuse^2$ . And since 2 and 5 are legs while c variable is the hypotenuse, the equation would be $2^2+5^2=c^2$ , or the first option.
