Opposite:
Just change the sign.
If it's a positive number, make it negative.
If it's a negative number, make it positive.
Absolute value:
Even easier.
Just throw away the sign, and you have it.
Answer:
To find the x intercept, let y=0. To find the y-intercept, let x=0. Hence, the x-intercept of the given equation is -2 and the y-intercept is -5/2.
Step-by-step explanation:
Let - 5x - 4y = 10 be the given equation.
Simplify the whole equation by dividing both sides by -1 :
To get the x-intercept, simply let y=0 :
- 5x + 4(0) = -10 (substitution)
- 5x = -10 (evaluate)
- x = -2 (simplify by dividing both sides of the equation by 5)
To get the y-intercept, simply let x=0 :
- 5(0) +4y = -10 (substitution)
- 4y = -10 (evaluate)
- y = -10/4 (simplify by dividing both sides of the equation by 4)
- y = -5/2 (simplify the fraction)
This is the way I got it the answer is v= 45
The function represents a reflection of f(x) = 5(0.8)x across the x-axis is f(x) = -5(0.8)^x
<h3>Reflection of functions and coordinates</h3>
Images that are reflected are mirror images of each other. When a point is reflected across the line y = x, the x-coordinates and y-coordinates change their position. In a similar manner, when a point is reflected across the line y = -x, the coordinates <u>changes position but are negated.</u>
Given the exponential function below
f(x) = 5(0.8)^x
If the function f(x) is reflected over the x-axis, the resulting function will be
-f(x)
This means that we are going to negate the function f(x) as shown;
f(x) = -5(0.8)^x
Hence the function represents a reflection of f(x) = 5(0.8)x across the x-axis is f(x) = -5(0.8)^x
