X² - 7x - 8 = 0
You can use the Viet theorem
x₁ + x₂ = -p
-1 + x₂ = 7
x₂ = 7+1
x₂ = 8

Answer:
We can write the range for w as : 18 ≤ w ≤ 34
Step-by-step explanation:
The perimeter of rectangle is given as :
P = 2 ( length + width)
or P = 2 l + 2 w
Now, given the length of the garden is 16 feet
Also given is that the perimeter of the garden must be at least 68 feet and no more than 100 feet.
So, this can be written as :
or,
Substitute l = 16, we get:
So, we can write the range for w as : 18 ≤ w ≤ 34
Answer:
15.4 degrees
Step-by-step explanation:
b= 53
h = 55
cos -¹( 53/53)= 15.4
Answer:
y=
Step-by-step explanation:
Notice for this problem, point(0,-5) and (5,1) is being given.
Use the formula (y2-y1)/(x2-x1)
(-5-1)/(0-5)
=6/5
This finds the slope of the function.
To find the y-intercept, it is where the graph first intercept the y-axis.
In this case, it intercept it at y=-5.
Thus, the answer is y=6/5x-5
