Write an equation perpendicular to y=-1/5x+9 that passes trough the point (-2,-2)
2 answers:
Answer: y=5x+8
Step-by-step explanation:
To find the perpendicular line, we know that the slope is the negative reciprocal of the equation. Therefore, we know that the slope will be 5. All we have to do is plug in the point to find the y-intercept.
[plug in (-2,-2)]
[multiply]
[add both sides by 10]
Now, we know the perpendicular equation is y=5x+8.

Answer:
$2500
Step-by-step explanation:
Given that,
The lost percentage = 9%
Amount she had = $22,750
We need to find Mrs. Fisher's original investment.
As she had lost 9%, it means she will remain with 91% of her investment. Let the original investment is x.
So,
So, her original investment is equal to $25000.
Answer:
The statement is false
Step-by-step explanation:
we know that
The tangent function will be positive when the sine function and the cosine function have the same sign
so
In the first quadrant the tangent function is positive
In the third quadrant the tangent function is positive
so
The statement is false
