Answer:

The water weighs 37.575 pounds.

Step-by-step explanation:

Given : 1 gallon = 8.35 pounds

To Find : Lena put 4.5 gallons in a bucket how much does the water weight

Solution:

Since 1 gallon of water weighs 8.35 pounds

So, 4.5 gallons of water weighs = $4.5 \times 8.35$

= $37.575$

Hence the water weighs 37.575 pounds.

A conditional statement is logically equivalent to a biconditional statement. True False pls help i have a test and i was absent

andreyandreev [35.5K]

Answer:

false.

Step-by-step explanation:

A conditional statement is something like:

If P, then Q.

This means that if a given proposition P is true, then another proposition Q is also true.

An example of this is:

P = its raining

Q = there are clouds in the sky.

So the conditional statement is

If its raining, then there are clouds in the sky.

A biconditional statement is:

P if and only if Q.

This means that P is only true if Q is true, and Q is only true if P is true.

So, using the previous propositions we get:

Its raining if and only if there are clouds in the sky.

This statement is false, because is possible to have clouds in the sky and not rain.

(this statement implies that if there are clouds in the sky, there should be rain)

Then we could see that for the same propositions, the conditional statement is true and the biconditional statement is false.

Then these statements are not logically equivalent.

The statement is false.

Answer:

(a) y = -4x + 4 (b) y = 2x + 3

solving steps:

note: m refers to slope and y₁ to y point and x₁ to x point

coordinates: (2,-4)

slope: -4

equation:

y - y₁ = m(x - x₁)

y - -4 = -4(x-2)

y = -4x + 8 - 4

y = - 4x + 4

coordinates: (1,5), (-1,1)

slope: $\sf \dfrac{y-y_1}{x-x_1}$

$\sf \dfrac{1-5}{-1-1}$

equation:

y - y₁ = m(x - x₁)

y - 5 = 2(x - 1)

y - 5 = 2x - 2

y = 2x - 2 + 5

y = 2x + 3
