what is the slope of a line b perpendicular to line a with equation y=7x-9

Answers

Answer 1

Answer:

The slope of line b would be -1/7.

Step-by-step explanation:

This happens because if you have the slope of any line and are trying to find the perpendicular line to said line, the slope of the perpendicular line will always be the opposite reciprocal of the original slope.

Then, all you need to do is find some points and graph the lines.

Answers

Answer:

Step-by-step explanation:

One of the things you should keep in mind about parallel lines is that there are 8 angles in this configuration.

4 are equal to one value

and 4 other angles which are the supplements to the first four. If you know the value of one of the 8 angles, you know the value of the other seven.

So angles (8) 6 4 and 2 are all 82 degrees.

Angles 1 3 5 7 and all equal to 180 - 82 = 98

Number 8 is given as 82. It's the red number.

number 6 is vertically opposite number 8 so those two are equal

Number 6 is an alternate interior angle to 4. Those two are equal.

Number 2 is number 4s vertically opposite angle. The others are all done somewhat the same way.

Answer:

j = 7

Step-by-step explanation:

First expand the right hand side:

3 = 3(j-6)

3 = 3j - 18

Then we can move 18 to the left hand side and calculate for j.

3 = 3j - 18

21 = 3j

j = 7

Two angles are supplementary. One angle is 40° more

angles.

Answers

Answer:

Let x = the measure of the smaller angle

Let 3x + 40 = the measure of the larger angle

x + 3x + 40 = 180

4x = 140

x = 35º

3x + 40 = 3(35) + 40 = 145º

f(x)

m = y - y1

x - x1

m = 2 - 0

m = 2

y - y1 = m(x - x1)

y - 0 = 2(x - 2)

y = 2x - 4

f(x) = 2x - 4

g(x)

(2/3, 0) and (1, 2)

m = y - y1

x - x1

m = 2 - 0

1 - 2/3

m = 6

y - y1 = m(x - x1)

y - 2 = 6(x - 1)

y = 6x - 4

g(x) = 6x - 4

since both equations are linear that means the graphs will be straight lines with y-intercept being -4 for both of the graphs.

if,

g(x) = f(k*x)

f(x) = 2x - 4

f(k*x) = 2k*x - 4

6x - 4 = 2k*x - 4

6x = 2kx

6 = 2k

k = 3.

The perimeter of a rectangle is 34 units. Its width is 6.5 units.

1. Write an equation to determine the length (l) of the rectangle.

2. Find the length of the rectangle.

Answers

Answer:

10.5 units

Step-by-step explanation:

Given

Perimeter P = 34 unitsWidth w = 6.5 unitsLength l = ?

Equation, in terms of l:

2(l + 6.5) = 34l + 6.5 = 17l = 17 - 6.5l = 10.5

Answer:

Equation:6.5 + 6.5 + L +L =34

Answer: 10.5

Step-by-step explanation:

To find perimeter you need L+W+L+W. You have a width of 6.5. When you plug that into the equation you get 6.5 + 6.5+ L+L=34. Combine like terms (6.5 +6.5). That leaves you with 13 + 2L = 34. Now, you want to subtract 13 from both sides to isolate the L. You now have 2L = 21. Now you should divide everything by 2. 21/2 = 10.5

A meteorologist says that there is a 50% greater chance of rain than no rain on Wednesday. What is the probability that it will rain on Wednesday?

Answers

Answer:

2/3

Step-by-step explanation:

The probability that it will rain on wednesday will be 0.75.

What is a expression? What is a mathematical equation? What is Probability?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. The formula to calculate the probability of occurrence of an event 'A' can be written as -  

P(A) = n(A)/n(S)

where -

n(A) = Number of outcomes favorable to event A.

n(S) = Total number of outcomes.

We have a meteorologist who says that there is a 50% greater chance of rain than no rain on Wednesday.

Assume that the probability that it will rain on wednesday be [x]. Now, we can write -

P[R] = P[N.R.] + 1/2

P[R] + P[R] = P[N.R.] + P[R] + 1/2

2 P[R] = 1 + 1/2

2 P[R] = 1.5

P[R] = 1.5/2

P[R] = 0.75

Therefore, the probability that it will rain on wednesday will be 0.75.
