y= x + 2 and  y = x^2 - 4

Substitute mx + b for y

x^2 - 4 = x + 2

Solve for x

x^2 - 4 = x + 2

x^2 - x - 6 = 0

(x - 3)(x + 2) = 0

x - 3 = 0; x = 3

x + 2 = 0; x = -2

Substitute the first x value  into the linear equation and solve for y

y = 3 + 2

y = 5

One solution is (3, 5)

Substitute the second x value into the  linear equation and solve for y

y = -2 + 2

y = 0

Another solution is (-2 , 0)

Which choice provides the best evidence for the
Thepotemich [5.8K]

The choice which provides the best evidence for the previous question is Lines 1-6 ("MIT....years"). The correct option is A.

Given a passage that is shown in the attached images.

Option A is the best answer. The previous question asked Brynjolfsson and McAfee what has led to technological advancements in the workplace since 2000. The answer, that weak job growth is the result of these advances, is supported by the first sentence of the first paragraph: to automated translation services - largely responsible for the growth. employment has weakened by over the last 10 to 15 years. Alternatives B, C, and D are incorrect because citation lines do not support an answer to the previous question about what Brynjolfsson and McAfee say led to advances in technology in the workplace since 2000; instead, they point to industries not specifically examined by Brynjolfsson and McAfee 2 (option B), speculate as to whether changes might also be happening in other countries (option C), and explain the importance of productivity in the marketplace in the decades following World War II. (option D).

Hence, the choice which provides the best evidence for the answer to the previous question from the passage is Lines 1-6 ("MIT . . . years").

OleMash [197]

Answer:

  76%

Step-by-step explanation:

Let f represent the score on the final. Then Inara wants the final grade to be ...

  0.25·74 +0.20·99 +0.55·x ≥ 80

  38.3 +0.55x ≥ 80

  0.55x ≥ 41.7

  x ≥ 41.7/0.55 ≈ 75.82

Inara needs a final exam grade of 76% or better to earn at least 80% in the course.

The graph shows the midday temperature in Cambridge over the summer.
Mariulka [41]

Answer:

a) 6°C

b) upward

maximum temperature: 18 °C

minimum temperature: 12 °C

Then:

range of temperatures: 18-12 = 6°C

b) The trend is upward because, given any temperature, the next one is higher.
