Answer:
Step-by-step explanation:
y= -1/4x
X² + 4x - 8 = 5
This is a simple quadratic equation. Let's move everything to the left side to start:
x² + 4x - 8 - 5 = 5 - 5
Now we have:
x² + 4x - 13 = 0
In a quadratic equation, x =
Therefore, we plug in a = 1, b = 4, and c = -13, and we find that x = -2 - sqrt{17} OR -2 + sqrt{17}.
Answer:
y = -5x + 2
Step-by-step explanation:
Slope-intercept form is written as y = mx + b.
m is the variable representing slope, how steep the line is.
b is the variable representing the y-intercept, when the graph hits the y-axis.
x and y, when substituted, tells you the points on the graph.
When writing the equation of a line, you need the slope and the y-intercept.
In y = mx + b, substitute m for -5 and b for 2.
y = -5x + 2
Answer:
Step-by-step explanation:
Area of the triangle
A = b*h/2
b = 18
h = 15
Area = 18*15/2
Area = 135
Area of Parallelogram
A = b * h
b = 18
h = 15
Area = 18 * 15
Area = 270
Note: The parallelogram = 2 * Area of Triangle.
