Solve and graph the inequality. −x4−6≥−8 {"version": "1.1","math": "-x4-6≥-8"} question 6 options: x ≤ 8 x < –4 x > 8 x ≥ –8 save question 7 (5 points) question 7 unsaved solve and graph the inequality. 6.7 ≥−0.2x + 4.5 {"version": "1.1","math": "6.7  ≥-0.2x  +  4.5"} question 7 options: x≥−11 {"version": "1.1","math": "x≥-11"} x≥−56 {"version": "1.1","math": "x≥-56"} x< −11 {"version": "1.1","math": "x< -11"} x < −56 {"version": "1.1","math": "x  <   -56"}

1. x < –4
The question is a bit ambiguous since x4 can be interpreted as x^4. Since there was no option for −x^4−6 ≥ −8 ,  I will solve the question assuming that the original question was −x(4−6)≥−8 
−x(4−6)≥−8 −x(-2)≥−8           ---> multiply x with -2 2x≥−8              > divide by 2x≥−4 
2.  x≥ -11
To solve inequality using > or < sign, you must be careful because multiplying the inequality with -1 will cause the sign to change direction(< will become > or vice versa). In this case, will solve the question without multiplying it with -1

6.7 ≥−0.2x + 4.5                 > move -0.2x to left, 6.7 to right
0.2x ≥ 4.5 - 6.7
0.2x ≥ -2.2
x≥ -11

Question 6: Option 1.

Question 7: Option 1.

Step-by-step explanation:

Question 6: The given inequality is

Add 6 on both sides.

Multiply both sides by -4. If we multiply or divide an inequality by a negative number, then we need to change the sign of inequality.

Therefore, the correct option is 1.

Question 7: The given inequality is

Subtract 4.5 from both sides.

Divide both sides by 2.2.

It can be rewritten as

Therefore, the correct option is 1.

Bi’m pretty sure hope it works
