Line p passes through (8,-6) and is perpendicular to the line 2x+y=-7.
The slope of line p is?

A- -2
B- -1/2
C- 1/2
D- 2

(How do I solve to find slope)


Answers

Answer 1

Answer:

C) 1/2

Step-by-step explanation:

The slope of a perpendicular line is the negative inverse.

First, convert the given line to slope-intercept form.

2x + y = -7

y = -2x − 7

The slope of this line is -2.  So the slope of the perpendicular line is:

m = -1 / (-2)

m = 1/2

Which of the quadratic functions listed is written in standard form?

OC. Y - 7 = -2(x + 3)?
O D. Y= (x+1)(x – 5)

Answers

Answer: A

Step-by-step explanation:

f(x)=ax²+bx+c is the standard form for quadratic functions. Looking at the answer choices, we can eliminate B, C, D. They are not the same as the given standard form. B and C are point-slope formulas, which are not standard form. D is in intercept form, therefore it is not standard form. This leaves us with A as the correct answer.

At a track meet, the 3 members of a relay race ran a total distance of 3/8 of a mile. if each runner ran the same distance. how far did each person run?​

Answers

Answer:

.125 of a mile

Step-by-step explanation:

If the total distance was 3/8 of a mile and there were 3 runners, then each runner ran ___________________.

Change the 3/8 to a decimal

3/8 = 0.375 of a mile

Since there were 3 runners divide the total distance by 3

0.375/3 = 0.125

Each runner ran 1/8 of a mile or 0.125 of a mile.

Step-by-step explanation:

[tex](2x + 23) + (9x - 5) = 11x + 18 \\ 11x + 18 = 95 \: \: \: \: 11x = 77 \\ x = 7 \\ abd = (2 \times 7) + 23 = 37 \\ dbc = (2 \times 9) - 5 = 13[/tex]

Answer:

x=7

m<ABD=37°

m<DBC=58°

Step-by-step explanation:

Add the two equations.  They need to equal 95.  Solve for x.

(2x+23)+(9x-5)=95

11x+18=95

11x=95-18

11x=77

x=7

Substitute 7 in for x to both equations to solve for the angle degrees.

m<ABD=2x+23 = 2(7)+23 = 14+23 = 37

m<DBC=9x-5 = 9(7)-5 = 63-5 = 58

Answers

Answer:

(0, - 6)

Step-by-step explanation:

The y- intercept is where the function crosses the y- axis.

This occurs when x = 0 , thus

From the table when x = 0, f(x) = - 6

The y- intercept is therefore (0, - 6 )

NO is an angle bisector. Solve for x.

A. x = -10
B. Not enough information
C. x = 10
D. x = 4

Answers

Answer:
x= -10

Explanation:

When solving for x with 2 equations given, you’d add 3x+10 with 7x-30 like so: 3x+10=7x-30. you ALWAYS work your way from right to left till you’ve got nothing on your right but a number with no variable, so subtract 7x with 3x, giving you 4x, so now your equation would be: 4x+10=-30. Now that there is a single number to the right, you start to rotate, so subtract 10 from -30, giving you -40, so now your equation would be: 4x=-40. This is the last step, so all you have to do is divide 4x to itself and to -40. You DO NOT add the variable x to your answer, so it should be: x=-10 as your final answer.

j + k + 46° = 180° (staright line angles)

92° + k + 46° = 180°

k = 180° - 138°

k = 42°

or, 4 = -2x + 8

or, 4 - 8 = -2x

or, -4 = -2x

or, 2 = x

Answer:

The value of x is 2.

Answer:

x = 1

Step-by-step explanation:

4 = -2( x - 2) + 4

4 = -2x - (-2) +4

4 = -2x + 2 + 4

4 = -2x + 6

4 - 6 = -2
