What is the solution to the inequality -.4x-1.2 &gt;.8
Mademuasel [1]

Answer:

x < -1

Step-by-step explanation:

Solve -.4x-1.2 >.8 for x.

Start by adding 1.2 to both sides, to isolate -0.4 x:

-0.4x > 0.4

Divide both sides by -0.4, remembering the reverse the direction of the inequality sign:

x < -1

Step-by-step explanation:

  1. put your finger on zero and move it to -1 then go up to positive 1 and put ur dot there.
  2. put ur finger on 0 again then go to -1 but now u move down to -2 and put ur dot there.
  3. now put ur finger on the zero and go to the opposite side to positive 2 then go down to -2 and put ur dot there. Hope that helps :)

4) Solve ∆ABC, a = 2.5 cm, c = 3.6 cm, and ∠A = 43°. Begin by sketching and labelling
mezya [45]

The length of b and angle B and C are 3cm, 45  degrees and 79 degrees respectively.

<h3>How to determine the parameters</h3>

To determine the angles and length of sides, we use the sine rule

The sine rule is thus:

\frac{sin A}{a} = \frac{sin B}{b} = \frac{sin C}{c}

Given;

  • a = 2. 5cm
  • c = 3. 6cm
  • ∠A = 43°

Let's find angle C

\frac{sin 43}{2. 5} = \frac{sin C}{3. 6}

cross multiply

0. 682 × 3. 6 = sin C × 2. 5

sin C = 2. 4552/ 2. 5

C = sin^-^1(0. 982)

C = 79°

To find length of b

b= \sqrt{c^2 - a^2}

substitute the values

b = \sqrt{3.6^2 - 2. 5^2}

b = \sqrt{6. 71}

b = 2. 59 cm

b = 3cm

To find angle B, we have

\frac{sin 43}{2. 5} = \frac{sin B}{2. 59}

cross multiply

0. 682 × 2. 59= sin B × 2. 5

sin B = 0. 7065

B = sin^-^1(0. 7065)

B = 45°

Hence, the length of b and angle B and C are 3cm, 45  degrees and 79 degrees respectively.
