Answer:
the slope is 0
Step-by-step explanation:
If 7 = -4, then the line will be horizontal on (-4) going on forever, never moving up or down. Therefore, there will be no slope.
Answer:
The statement is a tautology.
Step-by-step explanation:
We have the following statement:
To reduce the statement to a tautology we need to use the table of logical equivalences as follows:
by the the logical equivalence involving conditional statement.
by the the logical equivalence involving conditional statement.
by the Associative law.

by the Domination law.
Let's solve your inequality step-by-step.
5x+38<4(2−5x)
Step 1: Simplify both sides of the inequality.
5x+38<−20x+8
Step 2: Add 20x to both sides.
5x+38+20x<−20x+8+20x
25x+38<8
Step 3: Subtract 38 from both sides.
25x+38−38<8−38
25x<−30
Step 4: Divide both sides by 25.
<u>25x</u> <u>-30</u>
25 < 25
25
x< <u>−6</u>
<u>
</u> 5
