Answer:

10.7a - 8.1b

Step-by-step explanation:

the simplest form of the expression (14.2a + 9.8b) - (13.1b - 0.2a) - (3.7a + 4.8b)

(14.2a + 9.8b) - (13.1b - 0.2a)- (3.7a + 4.8b)

To subtract the expressions we multiply negative sign inside the second parenthesis, change the sign of each term in second and third parenthesis

14.2a + 9.8b - 13.1b + 0.2a-3.7a-4.8b

Now we combine like terms

14.2a +0.2a-3.7a = 10.7a

9.8b - 13.1b-4.8b=-8.1b

So the expression becomes

10.7a - 8.1b

<h3>What is the linear relationship?</h3>
  • A statistical word used to express a straight-line relationship between two variables is a linear relationship (or linear association).
  • Graphs and mathematical equations of the form y = mx + b can both be used to represent linear relationships.
  • In everyday life, linear relationships are quite prevalent.

The midpoint of the axis is=

  • 10+24/2
  • 34/2
  • 17

In the intercept form-

  • y= mx+b
  • y= mx+3
  • y= mx +3
  • 10 =m(1) + 3

subtracting 3 from both sides-

  • 7=m
  • Y = 7x+3

Hence, the rate of change is 7ft/yrs.

What are the solutions to the equation (x – 6)(X + 8) = 0?
Norma-Jean [14]

Answer:

x = - 8, x = 6

Step-by-step explanation:

Given

(x - 6)(x + 8) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 8 = 0 ⇒ x = - 8

6x + 4x - 1 = 2(5x + 4)
MatroZZZ [7]

Answer:NO SOL

Step-by-step explanation:

Simplifying and applying the distributive property, we get 10x-1=10x+8. Subtracting 10x from both sides, we get -1 = 8, which is impossible. Thus, there are no solutions.
