Write a word sentence as an inequality. A number k minus 8.4 is greater than 21.

Mathematics

Travka [436]3 years ago

Answer: k-8.4>21

Step-by-step explanation: K subtracted by 8.4 is greater than 21, so we start the equality off with our unknown variable K. Because K-8.4 is greater than 21, our symbol faces the direction of K-8.4 (symbol always faces the direction of the greater values).

What is an equation of the line that passes through the points (4,4) and (8.1)
andrey2020 [161]

Answer:

  • y = - 3/4x + 7

Step-by-step explanation:

<u>Use both points and find the slope:</u>

  • m = (1 - 4) / (8 - 4) = - 3/4

<u>Find the line, using point-slope form and point (4, 4):</u>

  • y - 4 = - 3/4(x - 4)
  • y - 4 = - 3/4x + 3
  • y = - 3/4x + 7

The ratio of Mike buying fish to Millie buying fish was 8 to 2. If in total they bought 150 pounds of fish. How many pounds did
Lady bird [3.3K]

Answer: Mike bought 120 pounds of fish and Millie bought 30 pounds  of fish.

Step-by-step explanation:

If the ratio is 8 to 2 then  8/10 will be the probability of Mike buying fist and 2/10 will be the probability of Millie buying fish.

Now multiply each fraction by the total number of pounds to find how many pounds each bought.

8/10 * 150 = 1200/10 = 120

2/10 * 150 = 300/10 = 30  

In this case, Mike bought 120 pounds of fish and Millie bought 30 pounds  of fish.

Line b passes through points (9, 1) and (1, 6). Line c passes through points (10, 7) and (2, 12). Are line b and line c parallel
andre [41]
<h2>Answer:  Lines b & c are parallel.⇄</h2>

Step-by-step explanation:

  • When lines are perpendicular, the product of their slope is -1 (the slopes are negative reciprocal).
  • When lines are parallel, they have the same slope.

Slope = ( y₂ - y₁) / (x₂ - x₁)

Slope of Line b = ( 6 - 1 ) ÷ ( 1 - 9 )

                         =  5  ÷  (- 8)

                         =   - ⁵/₈

Slope of Line c =  ( 12 - 7 )  ÷  ( 2 - 10 )

                         =  - ⁵/₈

⇒ Line b ║ Line c
