When graphing, its how much you rise and run
thats the formula when u have a graph and the question is asking for the slope.
you chose a point, and go down or up however many times it goes to the next point, and you run to the left however many times it gets you to get to that point.
if the line goes downward the slope is therefore negative, and if the line goes upward, the slope is therefore, positive.
m in math is meant to be slope, so $m= \frac{rise}{run}$

Answer: 1/3

Step-by-step explanation: In algebra, we use the word slope to describe how steep a line is. Slope can be found using the ratio rise/run between any two points that are on that line.

For the line in the image provided, let's use the points A and B to find its slope. To get from point A to point B on this line, we would rise 1 unit and run 3 units. So the slope of this line or its rise over run is 1/3.

The variable that is used to represent slope is m. So for this line we would say that m = 1/3. It's important to understand that no matter what two points you choose along this line, the slope or rise over run can always be simplified to 1/3.

Given a polynomial f(x), if (x − 4) is a factor, what else must be true?

ollegr [7]

Answer:

$f(4)=0$

Step-by-step explanation:

The Remainder Theorem states that when you divide a polynomial $f(x)$ by a linear factor $(x-a)$ , where $a$ is a constant, the remainder is $f(x)$ evaluated at $x=a$

Moreover, according to the Factor Theorem, an extension of the Remainder Theorem, if the remainder of the function $f(x)$ is 0 when evaluated at $x=a$ , then $(x-a)$ is said to be a factor of the polynomial $f(x)$

Given the 2 theorems above, it follows that if $(x-4)$ is a factor of $f(x)$ , then the remainder is equal to 0 when $f(x)$ is evaluated at $x=4$

Which means $f(4)=0$

Third answer choice is correct.

The scatter plot shown gives the relationship between concentration and absorbance of a particular chemical, along with the line

Vesnalui [34]

Answer:

B) 0.24

Step-by-step explanation:

As we plot the point on the best fit line for the concentration of 0.2 the absorbance level predicted should be 0.24.

Z varies jointly as x and y. z=60 when x=5 and y=6. find z when x = 7 and y=3

Aneli [31]

Answer:

z = 42

Step-by-step explanation:

The question can be answered in 2 steps as follows:

Step 1: Calculation of the constant of the variation

The equation for the joint variation can be given as follows:

z = cxy ................... (1)

Where;

z = 60

c = constant = ?

x = 5

y = 6

Substituting the values into equation (1) and solve c, we have:

60 = c * 5 * 6

60 = c * 30

c = 60 / 30

c = 2

Step 2: find z when x = 7 and y = 3

Since from Step 1 c = 2, we now use equation (1) and substitute the values into it to find z as follows:

z = 2 * 7 * 3

z = 42

The possible values of x are given by x+8=<6. The greatest possible value of 7x is_____

kozerog [31]

Answer:

The possible values of x is given by $x\leq -2$ and they include: -2, -3, -4, -5, -6 and so on

The greatest possible value of 7x is $-14$

Step-by-step explanation:

We are given the equation: x + 8 <= 6

Let collect the like terms:

$x + 8 \leq 6\\x\leq 6 -8\\x \leq -2$

Therefore, x <= -2 and the possible values include: -2, -3, -4, -5, -6 and so on

To find the greatest possible value of 7x is when x = -2.

$7x = 7 * -2\\7x = -14\\$ .

I do not even know where to begin. Please help.

xenn [34]

F(x) = 2x + 1 when x <= -5
Now -10 is less than -5 so we plug x = -10 into 2x +1:-

f(-10) = 2(-10) + 1 = -19 answer

Now f(x) = x^2 when -5< x < 5
x =2 is within this range so f(2) = 2^2 = 4 answer

You can calculate the other 3 values by a similar method
