Answer:
B
Step-by-step explanation:
Answer:
y = -6x + 31
Step-by-step explanation:
In order for us to make this an equation of the form y = mx + b we have to find the slope.
The formula for slope is rise/ run. The rise is 6 and the run is -1.
So, the slope is 6/-1 or -6.
Our equation is now: y = -6x + b
Substituting 4,7 into the equation we get 7 = -24 + b
So, b = 31.
To check out answers we substitute 5,1 in and it works.
The larger number is 200. The ratio is 20:10 and 200 + 100 = 300.
The function g whose graph represents the indicated transformation of the graph of f(x)=x+2; translation 2 units right is g(x) = x
<h3>Translation of functions</h3>
Translation is a technique used to change the position of an image on an xy-plane. Given the function below;
f(x) = x +2
If the expression is translation 2 units to the right, the translation rule will be:
g(x) = f(x )- 2
Substitute
g(x) = x + 2 - 2
g(x) = x
Hence the function g whose graph represents the indicated transformation of the graph of f(x)=x+2; translation 2 units right is g(x) = x

The measure of the angle of elevation from the ground to the top of the ladder is 68.73 degrees
<h3>Angle of elevation and depression</h3>
These method is used to determine the side and angles of a triangle
From the question given, we have the following parameters
Base of the building = 7feet (Adjacent side)
Height of the building = 18 feet (Opposite side)
Required
angle of elevation of the building
Using the SOH CAH TOA identity
tanФ = opp/adj
tanФ = 18/7
Ф = 68.73 degrees
Hence the measure of the angle of elevation from the ground to the top of the ladder is 68.73 degrees
