Step-by-step explanation:

m= y2 - y1/ x2 - x1( slope of a line)

m = 8 -0 / 7- 0

8/7 = m

m = 1.1

since m =y - y1/ x - x1

1.1 = y - 0/ x-0

1.1 = y/x(cross multiply)

y = 1.1 x

y -1.1 x = 0

or

y - 8/7 x = 0

Answer:

Step-by-step explanation:

See the steps below:

First Method: (By splitting the middle term)

We have to find p and q such that p+q = 20 and

pq = 3×(-7) = -21

Let us looks for the pair of factors of -21 such that their sum is 20 and product is -21.

20 = 21 - 1 and -21 = 3(-7)

∴ 3x² + 20x - 7 = 3x² + 21x - 1x - 7

= 3x(x + 7) -1(x + 7)

= (x + 7)(3x - 1)

Second method: (Using the factor theorem)

Answer:

Step-by-step explanation:

Answer:

1.) x = -5

   y = -4

Point to graph: (-5, -4)

2.) x = 0

    y = -6

Point to graph: (0, -6)

3.) x = 5

    y = 8

Point to graph: (5, 8)

Step-by-step explanation:

Substitute x for the given value, then find y.

1.) -2(-5)-5y = 30

10-5y = 30

-5y = 20

y = -4

2.) -2(0)-5y = 30

-5y = 30

y = -6

3.) -2(5)-5y = 30

-10-5y = 30

-5y = 40

y = -8

Answer:

y values are

-4

-6

Answer:

L = (18r - 12)/W

Step-by-step explanation:

A = L * W

18r - 12 = L * W

(18r - 12) = L * W

(18r - 12)/W = L

There are 4 numbers (any number from 0-9) in a 4-digit number and the starting number should be 1 or bigger than 1. The thousands place in a 4-digit number cannot be 0. The smallest 4 digit number is 1000 and the greatest 4 digit number is 9999. There are 9000 four-digit numbers in all

Answer:

-1/4

Step-by-step explanation:

Use the slope formula

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\frac{-8-(-5)}{0-(-12)}[/tex]

Which equals -1/4

Answer:

Step-by-step explanation:

Given points:

Use slope formula:

[tex]\\ \sf\longmapsto Slope=m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{-2+3}{-5+3}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{1}{-2}[/tex]

The value of x in the equation [tex]\frac{x}{2} = \frac{x^2}{x - 2}[/tex] are x = 0 and x = -2

The expression is given as:

[tex]\frac{x}{2} = \frac{x^2}{x - 2}[/tex]

Cross multiply

[tex]x(x - 2) =2 * x^2[/tex]

Open the bracket

[tex]x^2 - 2x =2x^2[/tex]

Collect like terms

[tex]- 2x =2x^2 - x^2[/tex]

Evaluate the like terms

[tex]- 2x =x^2[/tex]

Rewrite as:

[tex]x^2 + 2x =0[/tex]

Factor out x

x(x + 2)  =0

Expand

x = 0 or x + 2 = 0

Solve for x

x = 0 or x = -2

Hence, the value of x are x = 0 and x = -2

Step-by-step explanation:

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

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.
