Find the rate of change: y = 5x - 2


A. 5

B. -2

C. 1/5

D. 2

Answers

Answer 1

Answer:

D. 2

Step-by-step explanation:

y = 5x - 2

At x = 0; y = 5(0) - 2 = - 2

(0, -2) is one point. It is Y intercept.

At Y = 0 ; 5x - 2 = 0 ; x = 2/5

(2/5, 0), is another point on the line.

Since it is a fraction , use your imagination to get two integers as co-ordinates.

At y = 8 ; 5x -2 = 8; 5x = 8 + 2 = 10 ; x =

(10/5) = 2

I Hope this helps!

Answers

Answer:

A and C

Step-by-step explanation:

Let's begin with simplifying the first expression

4x + 5x + 6 − 5x − 4

After adding and subtracting like terms, you end up with:

4x + 2

A would be a correct answer because the expression provided in that letter is the same as the original expression

B would be wrong

C would be correct too, after subtracting like terms, you end up with 4x + 2

D would be wrong

Answer:

A 4x + 2

C 9x − 5x + 2

Step-by-step explanation:

To solve;

4x + 5x + 6 − 5x − 4

Answer:

-6 degrees each minute

Step-by-step explanation:

if the temperature fell 48 degrees in 8 minutes, we must divide 48 by 8.

48 / 8 = 6

It fell 6 degrees every minute

Since we are talking about temperature dropping, it is negative

-6 degrees each minute

Problem 4 is correct.

You flip the y coordinate of point S from -4 to +4. The x coordinate stays the same.

=====================================================

Problem 5

Focus on the points W and X. Because the y coordinates are both 1, we subtract the x coordinates to get 4-1 = 3. The distance from W to X is 3 units. This is another way of saying segment WX is 3 units long. This applies to the preimage.

Then we're told the image has W'X' = 6 which is twice as long as WX = 3. Therefore, the scale factor is 2.

We can write it like this:

[tex]\text{scale factor} = \frac{\text{image length}}{\text{preimage length}} = \frac{W'X'}{WX} = \frac{6}{3} = 2[/tex]

This indicates that each side of W'X'Y'Z' is twice as long compared to each corresponding side of WXYZ.

How many solutions does the equation 10k-10k= 0 have? No solution,one solution,or infinite solutions?

Answers

Answer:

  infinitely many

Step-by-step explanation:

You want to know the number of solutions to the equation 10k -10k = 0.

Identity

The given equation can be simplified to ...

  0 = 0

It is true no matter what value is chosen for k. It has infinitely many solutions.

<95141404393>

The equation 10k - 10k = 0 has infinitely many solutions.

The equation 10k - 10k = 0 can be simplified as 0 = 0.

In this case, the variable "k" is eliminated from the equation, and we are left with a true statement that states 0 is equal to 0. This equation is an example of an identity, where both sides of the equation are always equal, regardless of the value of "k".

Since the equation is true for any value of "k", it means that any value of "k" would satisfy the equation. Therefore, this equation has infinitely many solutions.

When we have an equation with the same term on both sides that can be simplified to a true statement, it means that the equation is an identity. In this particular case, no matter what value we substitute for "k", the equation will always hold true.
