Another question 5x + 8 = 7x + 2

Mathematics
1 answer:
DochEvi [55]3 years ago
8 0

Answer: x=3

Step-by-step explanation: Subtract 2 from both sides and subtract 5x from both sides. Then you'll end up with 6 = 2x. Then divide through by 2 on both sides and you're left with x=3.

If the sidewalks are wet, then it has been raining determine the truth of each conditional
Debora [2.8K]

The hypothesis (If the sidewalks are wet) of this conditional statement is true, but the conclusion (it has been raining) is false.

<h3>What is a conditional statement?</h3>

A conditional statement can be defined as a type of statement that can be written to have both a hypothesis and conclusion. This ultimately implies that, it typically has the form "if P then Q."

Where:

P and Q represent sentences.

<h3>What is a hypothesis?</h3>

In Science, a hypothesis is primarily considered to be a tentative or an educated guess and it can be defined as a testable explanation for an observation or a specific experimentation (scientific) problem, especially by using the "if . . . then . . . because" format..

The hypothesis (If the sidewalks are wet) of this conditional statement is true, but the conclusion (it has been raining) is false. Also, this can be proven with this counterexample "If the sidewalks are wet, then it is cause of an erosion/irrigation."

What is the discriminant of 3x2 + 6x = 2?. a.12. b.18. c.42. d.60
Vikki [24]
<u><em>Answer:</em></u>
D. 60

<u><em>Explanation:</em></u>
<u>The general form of the quadratic equation is:</u>
ax² + bx + c = 0

<u>The given equation is:</u>
3x² + 6x = 2
This can be rewritten as:
3x² + 6x - 2 = 0

<u>By comparison, we can find that:</u>
a = 3
b = 6
c = -2

<u>Now, the discriminant of a quadratic equation is given by:</u>
b² - 4ac

<u>Substitute with the given values to get the discriminant for the given equation as follows:</u>
b² - 4ac = (6)² - 4(3)(-2) 
             = 36 - (-24)
             = 36 + 24
             = 60

Hope this helps :)

A fishing boat is hauling up a lobster trap. A machine called a winch pulls the trap up at a constant rate of 85 feet per minute
alexandr402 [8]

Answer:

A, C, D

Step-by-step explanation:

We know that velocity is 85 feet/minute, and distance is velocity * time, so we can multiply 85 by time to see if it equals the output

(A) 1*85-85

(B) 0.85*85 = 72.75

(C) 0.2*85 = 14

(D) 3.5*85 = 297.5

(E) 4* 85 = 340

A, C, and D match up
