we have the function

f(x)=(x-15)(x+1)(x-10)

we know that

The zero's of the function are the values of variable x when the value of the function is equal to zero

so

in the given function the zero's are

x=15\\x=-1\\x=10

therefore

<u>the answer is</u>

x=15

The answer should be x=15 because once u subtract 15-15 u get 0 and then u substitute 15 in "x" and then. Multiply 0 by everything else n u get 0:))

How to do: -8(1-a)=-7-(1-3a)
Fiesta28 [93]

In this question, you're solving for a.

Solve for a:

-8(1 - a) =-7 -(1 - 3a)

<em>use the distributive property</em>

-8 + 8a = -7 -(1 - 3a)

-8 + 8a = -7 - 1 + 3a

<em>combine like terms</em>

-8 + 8a = -8 + 3a

<em>subtract 3a from both sides</em>

-8 + 5a = -8

<em>add 8 to both sides</em>

5a = 0

<em>divide both sides by 5</em>

a = 0

What is mKNL?<br> Enter your answer in the box.
sergejj [24]

Answer:

102°

Step-by-step explanation:

As the vertically opposite angles are equal,

5x+2={3(x+14)

Now let's solve for x now

5x+2=3(x+14)\\

5x+2=3x+42

5x-3x=42-2

2x=40

\frac{2x}{2} =\frac{40}{2}

x=20 \\

Now let's find the value of KNL

3(x+14)\\3(20+14)\\3*34\\102

Hope this helps you.

Let me know if you have any other questions ;-)

What is the slope of the line that passes through the points (1, -2) and (3, -5)?
Ksivusya [100]

Slope of the line is -3/2

Step-by-step explanation:

  • Step 1: Given points are (1, -2) and (3, -5)
  • Step 2: Equation for slope, m = (y2 - y1)/(x2 - x1)

⇒ m = (-5 - -2)/(3 - 1) = -3/2

Suppose John is a high school statistics teacher who believes that scoring higher on homework assignments leads to higher test s
EleoNora [17]

Answer:

A. R2 = 0.6724, meaning 67.24% of the total variation in test scores can be explained by the least‑squares regression line.

Step-by-step explanation:

John is predicting test scores of students on the basis of their home work averages and he get the following regression equation

y=0.2 x +82.

Here, dependent variable y is the test scores and independent variable x is home averages because test scores are predicted on the basis of home work averages.

The coefficient of determination R² indicates the explained variability of dependent variable due to its linear relationship with independent variable.

We are given that correlation coefficient r= 0.82.

coefficient of determination R²=0.82²=0.6724 or 67.24%.

Thus, we can say that 67.24% of total variability in test scores is explained by its linear relationship with homework averages.

Also, we can say that, R2 = 0.6724, meaning 67.24% of the total variation in test scores can be explained by the least‑squares regression line.
