Answer:

3 sqrt(10)

Step-by-step explanation:

To find the distance, we use the formula

d = sqrt( ( x2-x1)^2 + (y2-y1)^2)

  = sqrt( ( 2- -1)^2 + ( -4-5)^2)

  = sqrt( (2+1)^2 +(-4-5)^2)

  = sqrt( 3^2 +(-9)^2)

  = sqrt( 9+81)

 = sqrt(90)

= sqrt ( 9*10)

  3 sqrt(10)

Answer:

The correct options are;

The equation of the function is 2·y = -25·x + 200

The equation of the function is y = -25/2·x  + 100

The x-intercept of the function is (8, 0)

Step-by-step explanation:

From the graph of the function, the y-intercept is observed at (0, 100), the x-intercept occurs at (8, 0)

Therefore, we have the slope, m given by the following relation

Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}

Where:

y₁ = 100

x₁ = 0

y₂ = 0

x₂ = 8

Which gives;

m =\dfrac{0-100}{8-0} = -12.5

The equation in slope can be found as follows

y - 100 = -12.5×(x - 0)

y = -12.5·x  + 100 = -25/2·x  + 100

Multiplying by 2 gives;

2·y = -25·x + 200

25·x + 2·y =  200

Therefore, the correct options are;

The equation of the function is 2·y = -25·x + 200

The equation of the function is y = -25/2·x  + 100

The x-intercept of the function is (8, 0).

What is the product of (3x+5) and (x+4)
kodGreya [7K]

For this case we must find the product of (3x + 5) (x + 4)

By definition, the distributive property states that:

(a + b) (c + d) = ac + ad + bc + bd

Then, according to the expression we have:

3x ^ 2 + 12x + 5x + 20 =\\3x ^ 2 + 17x + 20

Answer:

3x ^ 2 + 17x + 20

Option C

Jim is a furniture salesman. his weekly pay is $300 plus3.5% of his total sales for the week.jim sell x dollar's worth of furnit
Lesechka [4]
For this case, the first thing we must do is define a variable.
 We have then:
 x: total sales for the week
 We now write the equation that models the problem.
 We have then:
 p (x) = 0.035x + 300
 Answer:
 a function, p (x), which can be used to determine his pay for the week is:
 p (x) = 0.035x + 300
