What is the solution to the inequality below?

−x + 5< 20

Answers

Answer 1

Answer:

x>−15

Step-by-step explanation:

−x+5<20

Step 1: Subtract 5 from both sides.

−x+5−5<20−5

−x<15

Step 2: Divide both sides by -1.

−x

−1

<

15

−1

x>−15

Answer:

x>−15

Answer 2

Answer:

x>-15 would be the answer!

Step-by-step explanation:

In the equality −x + 5< 20, you want x to be by its self. First of all, you'll subtract 5 on both sides so now you will have -x<15. Now, you must get rid of the negative so divide -1 to both sides. Oh, looks like you will have to flip the symbol since you're dividing a negative. In the end, you'll have an answer of x>-15.

The given lines are parallel in nature.

What is slope?

Numerical measure of a line's inclination relative to the horizontal.

Equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation.

Given:

y = 5x + 2 and y = 5x – 1

The slope for line 1 is 5.

David made an error when determining the product of (–2.5)(–8.3). Step 1: (–2.5)(–8.3) = (–8.3)(–2.5) Step 2: = (–8.3)(–2) + (–8.3)(–0.5) Step 3: = (–16.6) + (–4.15) Step 4: = –20.75 In which step did David make his first error? Step 1 Step 2 Step 3 Step 4

Answers

Answer:

Step 3.

Step-by-step explanation:

We need to tell the incorrect step in the given problem for the product of        (–2.5)(–8.3)

Step 1. (–2.5)(–8.3) = (–8.3)(–2.5)

Step 2:

We can write -2.5 = -(2+0.5)

(–8.3)(-(2+0.5)) = (–8.3)(-2)+(-8.3)(-0.5)

= 16.6 + 4.15

Step 3.

= 20.75

He has done an error in step 3. It should be 16.6 + 4.15 instead of (–16.6) + (–4.15). As a result, he get incorrect answer.
