y=3x+5

plug your coordinate points into the equation for slope (left corner or the paper)

multiply by the denominator on both sides of the equation

x-6 cancels out and leaves y-23=3(x-6)

multiply x and -6 by 3

add 23 to both sides to isolate y

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

3 = 3j - 18

Answers

f(x)

(2, 0) and (3, 2)

m = y - y1

x - x1

m = 2 - 0

3 - 2

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.

I hope the answer is correct. All the best!

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.

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.

Two step equations word problems

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
