Answer:

(- 5, - 7 )

Step-by-step explanation:

Equate f(x) and g(x), that is

2x + 3 = - 4x - 27 ( add 4x to both sides )

6x + 3 = - 27 ( subtract 3 from both sides )

6x = - 30 ( divide both sides by 6 )

x = - 5

Substitute x = - 5 into either of the 2 functions for y- coordinate

Substituting into f(x)

f(- 5) = 2(- 5) + 3 = - 10 + 3 = - 7

Thus point of intersection = (- 5, - 7 )

What is an equation of the line that passes through the points (-6, 5) and (6, 7)?

e-lub [12.9K]

Answer:

$y=\frac{1}{6}x+6$

Step-by-step explanation:

Let $(x_1,y_1)\rightarrow(-6,5)$ and $(x_2,y_2)\rightarrow(6,7)$

Determine slope

$m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{7-5}{6-(-6)}\\ \\m=\frac{2}{6+6}\\ \\m=\frac{2}{12}\\ \\m=\frac{1}{6}$

Use either ordered pair to find the y-intercept

$y=mx+b\\\\7=\frac{1}{6}(6)+b\\\\7=1+b\\\\6=b$

Final equation

$y=\frac{1}{6}x+6$

What is the probability of getting blue and green on a spinner that is 3/10 and 1/5 blue

DaniilM [7]

So 3/10 green and 1/5 blue. First, let's convert them into equal fractions. Now we have 3/10 and 2/10. When combined, it is 5/10. That means there is a 50% chance you will land on blue or green.
