{4z=8} {3x-2z=11} {x-4y+z=11}

Mathematics
1 answer:
tino4ka555 [31]2 years ago
3 0

Step-by-step explanation:

4z = 8

z = 8/4

z = 2

3x - 2z = 11

3x - 2.2 = 11

3x - 4 = 11

3x = 11 + 4

3x = 15

x = 15/3

x = 5

x - 4y + z = 11

5 - 4y + 2 = 11

-4y = 11 - 5 - 2

-4y = 4

y = 4/-4

y = -1

Solution → {x,y,z} = {5,-1,2}

An egg of a certain kind of insect called a Tachinidae is 0.00002 meters long. What is this length in scientific notation?
GaryK [48]
2.0x10^-5 or 2.0E-5 —this is because as a small decimal number, you move the decimal to the right five spaces and then add a negative to the decimal to indicate that when you translate back (from scientific notation to 0.00002) you will move the decimal to the left

Help 30 points and i will mark brainliest for the best answer which will be more points
klasskru [66]

Answer:

See below

Step-by-step explanation:

From the table we see there is a relation between x and y values

Every step change of x = 0.5, every step change of y = 2

<u>This relation is linear. The formula for linear function is:</u>

  • y = mx + b

<u>Using to pairs of points to get the slope and y-intercept</u>

  • (0, 60) and (1, 64)

<u>Calculating the slope:</u>

  • m = (64 - 60)/(1 - 0) = 4/1 = 4
  • y - intercept is 60 as per point (0, 60)

<u>So the function is</u>

  • y = 4x + 60
<h3>Part A</h3>
  • Yes. Described above
<h3>Part B</h3>
  • y = 4x + 60
<h3>Part C</h3>
  • Slope is the steepness of the line.
  • y -intercept is the lowest score with no time spent studying
