Solving the expression  -[-2(x-4) - |1-3|] = -2x18 we get value of x: x=\frac{3}{19}

Step-by-step explanation:

We need to solve the equation -[-2(x-4) - |1-3|] = -2x18 and find value of x

Solving:

-[-2(x-4) - |1-3|] = -2x18

Multiply -2 with terms inside the bracket

-[-2x+8 - |1-3|] = -2x18

Solving |1-3| we get |-2|=2

-[-2x+8 - 2] = -2x18

-[-2x+6] = -2x18

Multiply (-) sign with terms inside the bracket

+2x-6 = -2x18

Multiply 2x with 18

2x-6 = -36x

Add 36x on both sdides

2x-6+36x =0

38x-6 =0

Add 6 on both sides:

38x =6

Divide both sides by 38

x=\frac{6}{38}

Simplifying:

x=\frac{3}{19}

So, Solving the expression  -[-2(x-4) - |1-3|] = -2x18 we get value of x: x=\frac{3}{19}

Answer:

Yes, (0,4) is a solution

Step-by-step explanation:

We have to plug in 0 in x and 4 in y IN BOTH THE INEQUALITIES.

IF BOTH ARE TRUE, then the system of inequalities is TRUE.

<u>Let's check:</u>

y ≤ -3x+4

4 ≤ -3(0)+4

4 ≤ 4

Is 4 less than OR equal to 4? Yes. THis is satisfied.

<u>Now, checking 2nd one:</u>

y > x^2 + 3x - 2

4 > (0)^2 + 3(0) - 2

4 > -2

Is 4 greater than -2? Yes, it is. So this is satisfied as well.

Hence, (0,4) is a solution to the system of inequalities shown.

Can someone please help out? I’m stuck on this question and can’t figure it out for the life of me
Mumz [18]

The measure of angle A will be 61°

The sum of A and B is 122°

The sum of A B and C is 151°

<h3>How to calculate the angle?</h3>

It should be noted that complementary angles have an angle of 90°.

Therefore, the value of A will be:

= 90° - 29°

= 61°

The value of B will be:

= 90° - 29 = 61°

The value of A and B will be:

= 2 × 61°

= 122°

The value of A B and C will be:

= 122 + 29

= 151°
