What is the solution set for x2+12x=-11​

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

x^2 + 12x = -11

x^2 + 12x + 11 = 0

(x + 1)(x + 11) = 0

x + 1 = 0         x + 11 = 0

x = -1              x = -11

x = -1, x = -11

What is the slope of the line that passes through the points? (-4,4), (3,2)?

Answers

Hi there!

Step-by-step explanation:

SLOPE=(Y_2-Y_1)/(X_2-X_1)=(RISE)/(RUN)

(2-4)/(3-(-4))=(-2)/(7)

Slope is -2/7

Final answer is -2/7.

Hope this helps!

Have a nice day! :)

Thank you! :)

The formula of a slope:

m=(y_2-y_1)/(x_2-x_1)

We have the points (-4, 4) and (3, 2). Substitute:

m=(2-4)/(3-(-4))=(-2)/(3+4)=-(2)/(7)

Answer: The slope is - 2/7.

Mrs. Ishimitsu is installing a rubber bumper around the edge of her coffee table. The dimensions of the rectangular table are (2x2 – 16) feet and (–x2 + 4x + 1) feet. Which expression represents the total perimeter of the table, and if x = 3, what is the length of the entire rubber bumper?

Answers

Answer:

P = 2x² + 8x - 30

P = 12 (if x = 3)

Step-by-step explanation:

Perimeter Formula: 2l + 2w

Step 1: Find perimeter

2(2x² - 16) + 2(-x² + 4x + 1)

4x² - 32 - 2x² + 8x + 2

2x² + 8x - 30

Step 2: Plug in x = 3

2(3)² + 8(3) -30

18 + 24 - 30

42 - 30

joseph had a quarter of a cookie. ellen had a half of a different cookie. The peice joseph had was larger. how could ellens peice be smaller? explain.

Answers

My theory is the cookie could be smaller because Ellen's cookie might have been smaller as a full than Joseph's. 

For example, Joseph's cookie may have 24 pieces, while Ellen's cookie may have been 4 pieces.
The Cookie that joseph was eating was larger. Half of a small cookie is smaller than a quarter of a larger cookie.

Which statement is correct?A:A horizontal line has no slope.
B:A vertical line has a slope of zero.
C:A line that rises from left to right has a positive slope.
D:A line that falls from right to left has a negative slope.

Answers

Final answer:

The correct statement is B. A vertical line has a slope of zero.

Explanation:

The correct statement is option B: A vertical line has a slope of zero. A slope of zero means that there is no relationship between x and y. Graphically, the line is flat, with zero rise over the run. A vertical line goes straight up or down and has no change in the x-coordinate, resulting in a slope of zero.

For Example: Consider the equation x = 2. This represents a vertical line that passes through the point (2, y) for any value of y. Since the x-coordinate does not change, the slope is zero.

#SPJ2

Answer:

A line that rises from left to right has a positive slope

Step-by-step explanation:

Verify each statement

case A) A horizontal line has no slope

The statement is False

Because a horizontal line has a slope equal to zero

case B) A vertical line has a slope of zero

The statement is False

Because a vertical line has a undefined slope

case C) A line that rises from left to right has a positive slope

The statement is True

case D) A line that falls right to left has a negative slope

The statement is False

Because a is a positive slope
