What must be true about the slopes of two perpendicular lines, neither of which is vertical?

Mathematics

anzhelika [568]3 years ago
7 0

Answer:

A

Step-by-step explanation:

Here, we are to select which of the options best answer the question. The correct answer here is that the product of the slopes of the two lines is -1.

When we talk about perpendicular lines, these are lines that are at an angle of 90 degrees to each other.

These lines have slopes of which their product is -1. What this means is that one of the slopes is a negative reciprocal of the other. By multiplying these two slopes together, we get -1.

Say we have two perpendicular lines with slopes m1 and m2 respectively, the product of both slopes is equal to -1.

Mathematically in this case;

m1 * m2 = -1

Answer:

Because f(g(x)) = g(f(x)) = x, f and g <u>are </u> inverse functions.

Step-by-step explanation:

f(g(x)) = f(\frac{1}{4}\sqrt{x}) = 16(\frac{1}{4}\sqrt{x} ) ^{2} = 16(\frac{1}{16}x)=x

g(f(x)) = g (16x^{2}) = \frac{1}{4}\sqrt{16x^{2} } = \frac{1}{4}(4x) = x

Sierra drives for h hours at a rate of 2x miles per hour. Which expression shows the distance that she drives after h hours
Eva8 [605]

Answer:

Distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh

Explanation:

Distance traveled by a body = Velocity of the body * Time taken by the body

Here velocity of Sierra =  2x miles per hour

Time taken by Sierra = h hours.

Distance traveled by Sierra = 2x * h = 2xh

So distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh

two trains leave the station at the same time one heading east and the other west. the eastbound train travels 14 miles per hour
Xelga [282]
You should look to units of measure when setting up problems. when math is done correctly, the units cancel out just as numbers and variables do.

 (miles / hr) * hr = miles

Speed = (miles / hr)

So if the Train W is traveling at x miles/hr
Then Train E is traveling (x+14) miles/hr

The combined distance they two trains travel is 320 miles

2x + 2(x+14) = 320
2x + 2x + 28 = 320
4x + 28 = 320
4x = 292
x = 292/4
x = 73 miles/hr

remember we set x as the speed for Train W
so Train E is going 73 + 14 = 87 miles/hr
