The first mistake made in the steps to solve the equation is; Step 3 is incorrect and should be x = 10/8

<h3>How to solve algebraic equations?</h3>

We are given the algebraic expression;

6x - 1 = -2x + 9

Step 1; By addition property of equality, add 2x to both sides to get;

6x - 1 + 2x = -2x + 2x + 9

8x - 1 = 9

Step 2; By addition property of equality, add 1 to both sides to get;

8x - 1 + 1 = 9 + 1

8x = 10

Step 3; By division property of equality, divide both sides by 8 to get;

8x/8 = 10/8

x = 10/8

Step 4; By simplifying the fraction, we have;

x = 5/4

Step 3 shows 8/10 and as such it is the first mistake.

5x^3+9x^2+6x+1 times the polynomial x?
zhannawk [14.2K]

Answer:

(5x^{4} + 9x^{3} + 6x^{2}  + 1x)

Step-by-step explanation:

(5x^{3} + 9x^{2} + 6x + 1) * x

Multiplying the term by x, adds 1 to the power.

EG

5x^{3} * x = 5x^{3+1} = 5x^{4}

Therefore

(5x^{3} + 9x^{2} + 6x + 1) * =\\(5x^{4} + 9x^{3} + 6x^{2}  + 1x)

Question 2*
lilavasa [31]

Answer:

The average rate of change between these times is 68 miles per hour

Step-by-step explanation:

Here, we are to determine the average rate of change between hour 2 and hour 7

The distance traveled at hour 2 is 140 miles

The distance traveled at hour 7 is 480 miles

So we can say we have two points and we want to know the rate of change between these points

Mathematically, we can represent the rate of change as Δ

Thus, between the two different times, we have;

Δ = (D7-D2)/(T7-T2)

where (T7,D7) = (7,480) and (T2,D2) = (2,140) represents the time and distance at hour 2 and hour 7 respectively

Now inputing the values into the equation, we have;

Δ = (480-140)/(7-2) = 340/5 = 68 miles/hour
