Answer:
Slope: 4.5
y = 4.5x + 20
Step-by-step explanation:
Slope = rise/run = 45/10 = 4.5
y = mx + b
m= slope = 4.5
b= y-intercept = 20
y = 4.5x + 20
Answer:
8/5 or 1 3/5
Step-by-step explanation:
First you need to add the 5 to the 2/5 to make it 4 7/5, then subtract 3 4/5, then you have you aweser.
Answer:
1/3
Step-by-step explanation:
This is about the interpretation of the graph
From the graph, we can see the 2 lines representing function f(x) and function g(x).
Now for us to find the value of x in g(x) = k⋅f(x), we need to get a mutual x-coordinate where we can easily read their respective y-coordinate values.
We see that the best point for that is where x = -3.
For f(x), when x = -3, y = 1
For g(x), when x = -3, y = -3
we can rewrite them as;
x = -3, f(-3) = 1 and x = -3, g(-3) = -3
Let us plug in the relevant values into g(x) = k⋅f(x) to get;
-3 = k(1)
Thus; k = -1/3

Answer:
x = 16.4
Step-by-step explanation:
For right-angle triangles, we can use the trigonometry equations;
In this case, we need to use the sine equation in particular:
sinθ = opposite/hypotenuse
sin(66) = x/18
x = 0.91...(18)
x = 16.4438... ⇒ 16.4
