Answer:
The inverse is x/3 -1
Step-by-step explanation:
y = 3x+3
To find the inverse, exchange x and y
x = 3y+3
Solve for y
x-3 =3y+3-3
x-3 = 3y
Divide by 3
x/3 - 3/3 = 3y/3
x/3 -1 = y
The inverse is x/3 -1
Answer:
8,900
Step-by-step explanation:
Given Number: 8,937.2546
Determine the two consecutive multiples of 100 that bracket 8,937.2546
8,937.2546 is between 8,900 and 9,000
8,950 is the midpoint between 8,900 and 9,000
As illustrated on the number line, 8,937.2546 is less than the midpoint (8,950)
Therefore, 8,937.2546 rounded to the nearest hundred = 8,900
Answer:
First, we can make a proportion to find y
12/3=y/5
Cross multiply
3*y=12*5
3y=60
Divide both sides by 3
y=20
Next, we can use Pythagorean theorem to find x
a^2+b^2=c^2
a and b are the legs, and c is the hypotenuse
We know a is 15(12+3), b is x, and c is 25(20+5)
15^2+x^2=25^2
225+x^2=625
Subtract 225 from both sides
x^2=400
Take the square root of both sides
x=20
