Answers

Answer:

0

Step-by-step explanation:

let (-3,2) be (x1,y1)

and(3,2)be(x2,y2)

Now,

slope = y2-y1/x2-x1

=2-2/3-(-3)

=0/3+3

Write y+1=-2x-3 in standard form

Answers

Answer:

y=2x-4

Step-by-step explanation: this looks alot like an equation for slope is it?

Answer:

-2x - y = 4

Step-by-step explanation:

Standard Form: Ax + By = k

Note that while k is a variable, it stands for constant, which means the number with no variables attached would fill in the space. Isolate the constant. Subtract y, and add 3 to both sides:

y + 1 = -2x - 3

y (-y) + 1 = -2x - 3 (-y)

1 = -2x - 3 - y

1 = -2x - 3 - y

1 (+3) = -2x - 3 (+3) - y

4 = -2x - y

Set the equation so that it looks like the standard form equation given above:

-2x - y = 4 is your answer.

Find a · b.
a = −5, 1 / 2 ,
b = −5, 6

Answers

Answer:

a · b  = 28 units

Step-by-step explanation:

Given vectors

a = (-5, 1/2)

b = (-5, 6)

The scalar or dot product of the two vectors, given by a · b is

a · b  = (-5, 1/2) · (-5, 6)

To solve this, multiply the first term in a with the first term in b and add the result to the product of the second term in a and the second term in b. i.e

a · b  = (-5 x -5) +  (1/2 x 6)

a · b  = 25 + 3

a · b  = 28

Therefore, the dot product of a and b is

a · b  = 28 units

ej bisects def, m dej-5x+7, m JEF=8x-8. find x

Answers

Answer:

x = 5

Step-by-step explanation:

The information given has been sketched out in the attachment below.

Line segment EJ is an angle bisector of angle DEF. Therefore, m<DEJ = m<JEF.

The equation to find x would be expressed as follows:

5x + 7 = 8x - 8

Subtract 5x from each side (subtraction property of equality)

5x + 7 - 5x = 8x - 8 - 5x

5x - 5x + 7 = 8x - 5x - 8

0 + 7 = 3x - 8

7 = 3x - 8

Add 8 to both sides of the equation (addition property of equality)

7 + 8 = 3x - 8 + 8

15 = 3x

Divide both sides by 3

15/3 = 3x/3

5 = x

x = 5

#4. Identify the conclusion of the conditional statement: "I must reset the

clock if it's Daylight Saving time."*

A- I must reset the clock

B-It's Daylight Saving time

C-There is not conclusion

Answers

Answer:

C-There is not conclusion      

Step-by-step explanation:

In a conditional statement, there is a hypothesis and a conclusion. It is usually symbolized or represented by " If X, then Y." It is an if - then statement.

Here, the statement "X" is called the hypothesis and the statement "Y" denotes the conclusion. The conclusion is true if the hypothesis is true.

The conclusion of any conditional statement is the immediate phrase that follows the word 'then'.

In the context, the sentence "I must reset the  clock if it's Daylight Saving time." , the word 'then' is not there, so we can say that there is no conclusion in the statement.
