Answer:

k = 4

Step-by-step explanation:

k is the difference of y-intercepts (where the lines intersect with the y-axis). So, subtract the y-intercept of f(x) from the y-intercept of g(x).

2 - (-2) = 4

Hope that helps! :D

In kite ABCD, AB = BC and CD = DA. AB = (3x + 4), BC = x + 8, CD = y + 7, and DA = 2y + 5, find the perimeter of the kite

lana [24]

3x + 4 = x+ 8 > 3x - x = 2x > 2x + 4 = 8 > 8 - 4 = 4 > 2x / 2 crosses out > 4 / 2 = 2 > x=2
2y + 5 = y + 7 > 2y - y = y > y+ 5 = 7 > 7-5= 2 > y=2

the perimeter of the kite is 4

On Eduardo's workbench are the following

Maurinko [17]

Answer: 2/5

Step-by-step explanation:

Number of cans of red paint = 3

Number of cans of blue paint = 5

Number of cans of green paint = 8

Number of cans of yellow paint = 4

Total number of cans of paint = 20

The probability that Eduardo will

choose a can of red paint or a can of blue will be:

= P(red) + P(blue)

= 3/20 + 5/20

= 8/20

= 2/5

The probability is 2/5.

PLEASE HELP!!

Answer:

We can use excel regression data analysis tool to find the equation of the regression line that best fits the data.

The excel output is attached here.

Therefore, the equation of the linear regression is:

$\hat{y}=21.9028+1.5736x$

Where:

21.9028 is the intercept and 1.5736 is the slope.

$Given : \frac{\frac{4x}{5 + x}}{\frac{6x}{x + 2}}$

$\implies \frac{4x}{5 + x}\times\frac{x + 2}{6x}$

$\implies \frac{2}{x + 5}\times\frac{x + 2}{3}$

$\implies \frac{2(x + 2)}{3(x + 5)}$

$\implies \frac{2x + 4}{3x + 15}$
