Whats the rate of change in y=1.5x

Answers

Answer 1

Answer: "Rate of change" is how much one variable changes when the other changes. In linear equations this is know as "slope" (since slope equals the change in Y relative to the change in X). Next remember that any linear equation can be written in the form: y = mx + b, where m = slope and b = y-intercept (place where line crosses the y-axis). Therefore to figure out rate of change (or slope) of a linear equation simply rewrite the equation in the y = mx + b form. In your case, the equation is already written that way. y = 1.5x (note that in this case b = 0) So in this formula m = 1.5. The rate of change is equal to 1.5. Another way this could be said is that when x increases by one unit, y will increase by 1.5 units. Plugging in any set of numbers will show this is true: If X = 1; Y = 1.5 If X = 2; Y = 3 (X increases by 1; Y increases by 1.5) If X = 3; Y = 4.5 (Again X increase by 1; Y increase by 1.5) ...

Is 1/3 equivalent to 1/3x explain your reasoning

Answers

So the question is does 1/3 = 1/3x

To solve this, basically we just have to solve for x to see if it gives us a true statement. Since x is a variable, it could represent any number... so we have to determine whether the statement could be true with any other numbers as well...

1/3 = 1/3x divide each side by 1/3 (multiply by the reciprocal)
1/3 x 3/1 = x
1 = x

So when x = 1 then the statement 1/3 = 1/3x is true. If we put any other number as x the statement would be false... for example if you let x = 2, then 1/3 x 2/1 = 2/3... that does not equal 1/3 so it is a false statement and they are not equivalent when x = 2.

Your answer is, YES 1/3 is equivalent to 1/3x but ONLY when x = 1

Step-by-step explanation:

f(x)-g(x)=(3x^2+6x-1)-(2x^2-3x-3)

=3x^2+6x-1-2x^2+3x+3

=(3x^2-2x^2)+(6x+3x)+(-1+3)

=x^2+9x+2

Answer:

x^2-6x+7

Step-by-step explanation:

You can use synthetic division since you are dividing by a linear factor with leading coefficient 1. (You can also do synthetic division when dividing by a linear factor whose leading coefficient is not 1 but it is a bit trickier.)

So since we are dividing by x-2, 2 goes on the outside.

(If we were dividing by x+2, -2 would go on the outside.)

Now the thing that goes on top inside is the dividend, the numerator which is 1x^3-8x^2+19x-14. If you were missing any terms you would have to place a zero but we aren't. All exponents between 3 and 0 (inclusive meaning to include the 3 and the constant term) on variable x is accounted for.

2| 1 -8 19 -14

| 2 -12 14

1 -6 7 0

So the remainder is 0 and the quotient is x^2-6x+7.

the lenght of a rectangle is 2 cm less than 7 times the width. the perimeter is 60 cm . find the width and lenght

Answers

First, you want to establish your equations.

L=7W-2
P=60

This is what we already know. To find the width, we have to plug in what we know into P=2(L+W), our equation to find perimeter.

60=2(7W-2+W)

Now that we only have 1 variable, we can solve.

First, distribute the 2.
60=14W-4+2W

Next, combine like terms.

60=16W-4

Then, add four to both sides.

64=16W

Lastly, divide both sides by 16

W=4

To find the length, we plug in our width.

7W-2

7(4)-2

28-2

L=26
