A line with a slope of 8 passes through the points (-1,1) and (0,k). What is the value of k?
Diano4ka-milaya [45]

Answer:

k = 9

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 8

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)

m = \frac{k-1}{0+1} = k - 1 = 8 ( add 1 to both sides )

k = 9

ana wants to earn 88 percent in her chemistry class she has one quiz left to take on the first 5 quizzes she received a 74 perce
Alinara [238K]

Answer: 91

Step-by-step explanation: I assume you had a typo and mean what did Ana need on the 5th quiz since you only listed 4 quiz scores.

(74 + 92 + 83 + 100 + x)/5 = 88

(349 + x)/5 = 88

((349 +x)/5) x 5 = 88 x 5

349 + x = 440

x = 440-349

x  = 91

The planet Venus has a mass of 4.869 ∙ 1024 kilograms. Use scientific notation to express the planet’s mass in milligrams. 1 kil
Ostrovityanka [42]
<span>To do this you need to multiple 1,024 by 1,000,000 to get 1,024,000,000 and then convert it to scientific notation. For that you need to know how many places there are after the first number. In this case it is 9. This will be 1.024 x 10^9. You have to remember that it is to the power of however many numbers are after the first. So even though we show 3 digits after the . we still have to include those in the power.</span>
