Answer:
y = 2x - 6
Step-by-step explanation:
Use the slope-intercept form of the equation of a line.
y = mx + b
y = 2x + b
4 = 2(5) + b
4 = 10 + b
b = -6
y = 2x - 6
Okay, here we have this:
It says that: "Seven more than four times a number (x) is less than or equal to 6"
So, let's take the number as x and from the statement we obtain the following inequality:
7+4x≤6
And as it contains a variable the inequality is open by definition
Answer:
70 degrees
Step-by-step explanation:
The angle opposite x and x itself are vertical angles, meaning that they have the same angle measure. Since the sum of the interior angles of a triangle is 180 degrees:
x+55+55=180
x+110=180
x=180-110=70
Hope this helps!
Answer:
20/100=1/5
Step-by-step explanation:
find the gradient of the line to find the fraction
the line is 20 units high so the line starts and stops subtracting equals 20 and the line is 100 units long to get the gradient you find the rise over the run
