Thé vertex of the graph of the following function f(x)=x2+8x-2 is (-4,-18).
Step-by-step explanation:
the general slope intercept form is
y = ax + b
a is the slope. a parallel line must have the same slope.
in our case here it is -3.
b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).
we get b by using the point coordinates in the equation and solve for b :
-4 = -3×-9 + b = 36 + b
b = -40
so, the full equation of the parallel line is
y = -3x - 40
Answer:
73
Step-by-step explanation:
When you have a line intersecting another line, the angles produced by the intersection will be equal to 180.
This means that (-39 + x) + 146 = 180. Solve for x.
(-39 + x) + 146 = 180
-39 + x = 34
x = 73
L= length
W= width
Perimeter= 2L + 2W
substitute the known numbers
34 ft= 2(8 ft) + 2W
34= 16 + 2W
subtract 16 from both sides
18= 2W
divide both sides by 2
9 ft= W
ANSWER: The width is 9 feet.
