Answer:
Second choice.
Step-by-step explanation:
Option 1: solve the inequality. Add 7 to both sides, and multiply by -3 (don't forget that this makes the inequality switch direction!) to get or x > -9
Option 2. Plug 0 in it. You get -7 < 20, which is obviously true. So 0 is in the set of solution and it means B and C are possible solutions. So let's check another easy value. let's say -10. replacing it you get or
. But 23 is obviously greater than 20, which means -10 is not a part of the solution. Correct answer is B

Step-by-step explanation:
An expression is a <u>set of terms that are combined using addition, subtraction, multiplication, or division.</u> The following are examples of expressions:
Note: expressions do not equal anything.
In contrast, equations are <u>expressions that equal at least one term.</u> The following are examples of equations:
Note: equations <u>do</u> equal a term, as shown in the examples.
Answer:
Slope - intercept form
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the point (2,-4) and slope
Equation of the straight line passing through the point (x₁, y₁) and slope 'm'
y - y₁ = m( x-x₁ )
y - (-4) = ( x-2)
⇒ 5( y+4) = 3(x-2)
⇒ 5 y +20 = 3x -6
⇒ 3x - 5 y -6-20 =0
⇒ 3 x -5y -26=0
<u><em>Step(ii):-</em></u>
Slope - intercept form
5 y = 3x -26
