The table below show 2 equations. Equation 1: 3x-1=7+2 Equation 2: 2x+1+4=3 which statement is true about the solution to the tw

olya-2409 [2.1K]

You have not added your options, so I will just solve and hope that my answer is in your choices.

For the first equation we have:
3x-1=7+2
3x = 7+2+2
3x = 10
x = 10/2

For the second equation we have:
<span>2x+1+4=3
</span>2x = 3-4-1
2x = -2
x = -1

Therefore, there isn't a solution that satisfies both equations. Based on this, this system of equations has no solution.

Can someone please help me and write out the answer

Answer:

$- 30$

Step-by-step explanation:

$\sin {}^{ - 1} ( - \frac{1}{2} ) =$

Using the identity,

$\sin( - x) = - ( \sin(x) )$

$\sin( \frac{1}{2} ) = \frac{\pi}{6}$

$\sin {}^{ - 1} ( \frac{ - 1}{2} ) = - \frac{\pi}{6}$

Convert to degrees.

$- 30$

3. Emma said that when you multiply three negative decimals , the product will be positive . Use these numbers to answer the que

mina [271]

Using multiplication signal rules, it is found that:

A: Emma's statement is always false.

B: The result is always negative.

C: Emma's statement is always true.

The rule used for this exercise is as follows:

When two numbers of different signals are multiplied, the result is negative.
When two numbers have the same signal, the result is positive.

Part A:

Three numbers are multiplied, all negative.
The multiplication of the first two result in a positive number.
Then, this positive number is multiplied by a negative number, and the result will be negative, which mean that Emma's statement is always false.

Two examples are:

$-2.5(-3.8)(-2) = 9.5(-2) = -19$

$-2.5(-2)(-0.7) = 5(-0.7) = -3.5$

Part B:

The rule is that the result is always negative.

Part C:

The multiplication of the first two negative numbers result in a positive number.
Then, this positive number is multiplied by another positive number, and the result will be positive, which mean that Emma's statement is always true.

Two examples are:

$-2.5(-3.8)(2) = 9.5(2) = 19$
