What are the slope and the y-intercept of the linear function that is represented by the equation y=-10x+1

Answers

Answer:

The slope is $-10$ and the y-intercept is $1$ .

Explanation:

This function is written in slope-intercept form, which is $y=mx+b$ . In this form, $m$ is the slope and $b$ is the y-intercept.

In this case, $m=-10$ and $b=1$ , so those are the answers to this problem.

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We have the following equation:

$y = -10x + 1$

So we have to:

$m = -10\nb = 1$

Answer:

$m = -10\nb = 1$

How do I draw and shade a figure that represents 100% 100% and describe it in words ?

Answers

Answer:

The required shaded figure is shown in Figure 2:

Step-by-step explanation:

Consider the provided statement.

You need to draw a figure and need to shade 100%

Let us first draw a figure of circle as shown in Figure 1:

Remember: You can draw any figure or shape for example: square, rectangle, triangle etc.

Now, it is given that we need to shade the figure that represents 100%.

100% of a figure is also know as the whole figure.

Thus, shade the whole figure. Where you can use any color in order to shade.

The required shaded figure is shown in Figure 2:

Draw anything and color the whole thing in. And should be described as "one whole" in words.

Apply the distributive property to create an equivalent expression.
−9⋅(5j+k)=

Answers

Multiply the number outside the parenthesis by each term inside the parenthesis:

-9 * 5j = -45j

-9 *k = -9k

−9⋅(5j+k) = -45j - 9k

Answer:

$-45j-9k$ .

Step-by-step explanation:

The given expression is

$-9\cdot (5j+k)$

We need to find the equivalent expression of given expression.

According to the distributive property,

$a(b+c)=ab+ac$

Using distributive property the given expression can be rewritten as

$-9\cdot (5j)-9\cdot (k)$

$-45j-9k$

Therefore, the required expression is $-45j-9k$ .

Answers

Answer:

a) 60

b) 0.24

c) 150

Step-by-step explanation:

a) P(green) = ⅕

Expected no. = 300 × ⅕

= 60

b) total = 300

P(purple) = 72/300

= 6/25 = 0.24

c) P(blue) = 45/300

= 3/20 = 0.15

Expected no.: 1000 × 0.15

= 150

For which equation is 7 a solution

Answers

3x + 1 = 27

3(7) + 1 = 27

22 ≠ 27

FALSE

3(x + 1) = 24

3(7 + 1) = 24

3(8) = 24

24 = 24

TRUE

2x + 3(x - 4) = 21

2(7) + 3(7 - 4) = 21

14 + 3(3) = 21

14 + 9 = 21

23 ≠ 21

FALSE

x^2 - 8 = 42

7^2 - 8 = 42

49 - 8 = 42

41 ≠ 42

FALSE
