Use a table to find two consecutive integers between which the solution lies.

Mathematics
1 answer:
jolli1 [7]4 years ago
4 0

Answer:

  -5 and -4

Step-by-step explanation:

It is far easier just to solve the equation than to determine appropriate integer bounds on the solution.

In the attachment, we show a couple of initial trials at solutions. The nearness of y=5 to being correct suggests that the next higher integer may be helpful, too. It is.

We find -4 and -5 to bracket the solution.

_____

The actual solution is (3.4 -1.3)/-0.5 = -4.2.

Line k is graphed at right.
saw5 [17]

Answer:

See below ↓↓

Step-by-step explanation:

<u>Equation of line k</u>

  • y = mx + b
  • m = Δy/Δx (ratio of change in y to change in x) = 2/3
  • b = 3 (as y-intercept is [0,3])
  • ⇒ y = 2/3x + 3

<u />

<u>a. parallel line</u>

  • For parallel lines, slope (m) remains the same, but the y-intercept (b) changes
  • ⇒ <u>y = 2/3x + 1</u>

<u></u>

<u>b. perpendicular line</u>

  • For perpendicular lines, the slope (m) is the negative reciprocal of the original line and the value of b stays the same [it can be any point as long as it intersects the line]
  • ⇒ <u>y = -3/2x + 1</u>

Find the value of k so that the point A lies on the line given by equation.
PtichkaEL [24]

Answer:

k = 0

Step-by-step explanation:

<u>Explanation</u>:-

given straight line equation is k x+(k+1)y=2......(1)

The point A(2,2) lies on the equation is

substitute x = 2 and y=2

k(2) + (k+1)(2) =2

now simplify 2 k+2 k+2 = 2

subtracting '2' on both sides , we get solution is

4 k +2 -2 = 2-2

4 k =0

k = 0

aalyn [17]

Answer:

-75.955 kilometers

Step-by-step explanation:

multiply the speed by the time to get distance

the spacecraft is descending, so change in height will most likely be answered as a negative number

13.81 × 5.5 = 75.955
