Pls help I forgot all of this

Mathematics
1 answer:
bulgar [2K]4 years ago
6 0

Answer:

no solution

Step-by-step explanation:

Given the 2 equations

y = - 4x - 1 → (1)

8x + 2y = 5 → (2)

Substitute y = - 4x - 1 into (2)

8x + 2(- 4x - 1) = 5 ← distribute left side

8x - 8x - 2 = 5 ( add 2 to both sides )

0 = 7 ← not possible

This indicates the system has no solution

Layers of rock wear off during which of the following processes?
Maru [420]

Answer:

Exfoliation

Step-by-step explanation:

Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.

Rocky desert landscapes are particularly vulnerable to thermal stress. The outer layer of desert rocks undergo repeated stress as the temperature changes from day to night. Eventually, outer layers flake off in thin sheets, a process called exfoliation.

Can someone help me on the following?. 14.5n – 4 = 8 15. 2x + 5 – 4x = -3 16. 96=-6(-4 -3y)
leonid [27]
14. 5n - 4 = 8
           5n = 12
             n = 2.4

15. 3x + 5 - 4x = -3
              -x + 5 = -3
                    -x = -8
                     x = 8

16. 96 = -6(-4 - 3y)
      96 = 24 + 18y
      72 = 18y
        4 = y

17. 3(x - 5) = -14 + 17x
      3x - 15 = -14 + 17x
   -11x - 15 = -14
          -11x = 1
               x = -0.0909

18. 7z + 10 - z = 8z - 2(z - 5)
           6z + 10 = 8z - 2z + 10
           6z + 10 = 6z + 10
                   6z = 6z
                     z = z   (all real numbers are solutions)

Hope this helps.
