Answer:

The solution is in the method

Step-by-step explanation:

we start with

$-8.5x-3.5x=-78$

finding x

Combine similar terms

$-12x=-78$

Divide both sides by $-12$

$x=-78/-12$

$x=6.5$

To verify the solution, plug the value of x back into the original equation and assess the outcome

we know that

If x is indeed a solution to the equation, it must hold true in the equation

thus

For $x=6.5$

$-8.5(6.5)-3.5(6.5)=-78$

$-55.25-22.75=-78$

$-78=-78$ -------> holds true

hence

The calculated x is a valid solution of the equation

Jason can confirm the accuracy of his solution by substituting the calculated x value back into the original equation to check if it holds true. If the equality fails, it indicates that his calculated x is incorrect.

Sample Response: To check his result, Jason should replace x with the value he calculated in the initial equation. Following that, he should simplify using the order of operations. If the outcome is a true statement, then Jason's answer is validated.

The parent function f(x) = log3x has been transformed by reflecting it over the x-axis, stretching it vertically by a factor of

babunello [11817]

The third option is correct. Step-by-step explanation: Various transformations apply to a function f(x). If a transformation is applied downward by 'k' units, the function shifts down; if upward, it rises 'k' units. Additionally, if scaled vertically by a factor of 'b', it will stretch; if reflected over the x-axis, the operation is indicated. Thus, since the parent function has undergone reflection over the x-axis, a vertical stretch by a factor of 2, and a downward shift of three units, we can derive that the transformed function is presented.

To divide 16 teams into 4 divisions, you take 16 and divide by 4 to result in 4 equal groups of teams.

Erika is writing a coordinate proof to show that the diagonals of a rectangle are congruent. She begins by assigning coordinates

Leona [12618]

Answer:

Option C is the right choice.

Step-by-step explanation:

The given coordinates define a rectangle, and our objective is to show that the diagonals JL and KM are congruent.

We know that rectangles possess four right angles.

To prove the congruence of the diagonals JL and KM, we will utilize the Pythagorean theorem.

In triangle KLM, KL has a length of b units while LM has a length of a units. By applying the Pythagorean theorem $\sqrt(a^{2}+b^{2})=KM$

In triangle JML, JM is b units long, and LM remains a units long. We again can apply the Pythagorean theorem $\sqrt(a^{2}+b^{2})=JL$

Thus, we find that $\sqrt(a^{2}+b^{2})=KM=LM$ and option C is the correct choice.

It takes 40 min for a bus to travel the 36 miles from Framingham to Worcester. A car traveling from Worcester to Framingham move

Inessa [12570]

The bus's speed is calculated as: velocity (bus) = 36 miles / 40 min, which simplifies to velocity (bus) = 0.9 miles / min. Given that the car's speed is 1.5 times that of the bus, we find: velocity (car) = 1.5 * 0.9 miles / min, leading to velocity (car) = 1.35 miles / min. At the point where they meet, the total distance covered equals 36 miles. Hence: 1.35 t + 0.9 t = 36, and thus 2.25 t = 36 resulting in t = 16 min. They will converge after 16 minutes.
