For (x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)

(4,19)
(7,28)

slope=(28-19)/(7-4)=9/3=3/1=3

What’s the answer to this?
Galina-37 [17]

Answer:

(x-8y)(x-8y)

Step-by-step explanation:

write the expression as a product with the factors x and 8y

8^2 -2(x)8y+64y^2

multiply terms with equal exponents by multiplying the bases

x^2 -2 (x) 8y + (8y)^2

factor

(x-8y)^2 which is equal to c

A. 3/13<br><br> B. 10/39<br><br> C. 5/12<br><br> D. 8/13
ELEN [110]
The equation to find P(A and B) is P(A and B)= P(A) x P(B/A). P(B/A) stands for probability of B given A. First we need to find out the P(A). The P(A) is 8/13 because you have 13 marbles total and 8 white marbles. For P(B/A), it is 5/12. This is because there are 5 red marbles and given that A happened, there would only be 12 marbles left in the bag, leaving you with a 5/12 chance of getting a red marble. Now plug it in. 8/13 x 5/12 = 40/156, which simplifies down to 10/39. Thus, B is the answer.

The points (10, -10) and (8, -10) fall on a particular line. What is its equation in slope-intercept form?
blondinia [14]

y = 0x - 10 is the equation in slope-intercept form given that the points (10, -10) and (8, -10) which fall on a particular line. This can be obtained by the formula of the slope-intercept form of the line.

<h3>What is its equation in slope-intercept form?</h3>
  • Linear equation is an equation that models a linear function.

In linear equation the variables are raised to the first power.

Example, Linear equation: 2x + 3, Not a linear equation: x² + 5

The graph of a linear equation contains all the ordered pair that are solutions of the equation.

The equation of a line is given by,

y = mx + c, m is the slope of the equation, c is the y intercept

m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} },  y intercept is the y coordinate of the point where y crosses the y axis.

Here in the question it is given that,

The points (10, -10) and (8, -10) fall on a particular line.

 

We have to find the equation in slope-intercept form.

Slope of the equation will be,

m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} } ⇒ m = \frac{-10 -(-10) }{8 -10 } ⇒ m = 0  

y-intercept of the equation will be,

y = mx + c ⇒ -10 = 0 + c ⇒ c = -10

The equation of the line in slope-intercept form will be,

y = 0x -10

Hence y = 0x - 10 is the equation in slope-intercept form given that the points (10, -10) and (8, -10) which fall on a particular line.

Evaluate: .25 (1.2 x 3 - 1.25) + 3.45
iragen [17]

The order to us solve is:

  1. Parentheses
  2. Multiplication
  3. Sum and subtraction

Let's go:

25(1.2\times 3 - 1.25) + 3.45\\25(3.6-1.25)+3.45\\25\times 2.35 + 3.45\\58.75+3.45\\62.2

Therefore, the result is 62.2.
