Identify the zeros of the following function. f(h)=h(h-2)(2h-1)

1 answer:

5 0

{0, 2, 1/2}

f(h) = 0 when any set of parenthesis equals zero

1. h = 0

2. h - 2 = 0
add 2
h = 2

3. 2h - 1 = 0
Add 1
2h = 1
divide by 2
h = 1/2

X<25 true or false ? 100<4x -3x>-75 10>35-x Are these true or false ?

strojnjashka [21]

Answer:

What is the value of x

Step-by-step explanation:

X<25 true or false ? This says x is less than 25

100<4x

Divide each side by 4

100/4 <4x/4

25<x

This says x is greater than 25

-3x>-75

Divide each side by -3, remembering to flip the inequality

-3x/-3 < -75/-3

x < 25

x is less than 25

10>35-x

Add x to each side

10+x >35-x+x

10+x>35

Subtract 10 from each side

10-10+x>35-10

x>25

x is greater than 25

. Which of the following is equivalent to 7 - 2(x + 2) < -4 - 3(1 - x)?

andre [41]

Step-by-step explanation:

$7 - 2(x + 2) < -4 - 3(1 - x)$

First, let's distribute the terms outside each parentheses to get rid of them:

$7 - 2x - 4 < -4 - 3 + 3x$

$-2x + 3 < -7 + 3x$

Next, let's move the terms with an $x$ variable to the left side of the equation, and everything else to the right side:

$-2x -3x < -7 - 3$

$-5x < -10$

The running back for the Bulldogs football team carried the ball 5 times for a total loss of 11 1/4 yards. Find the average chan

Firdavs [7]

Answer:

$\displaystyle 2\ \frac{1}{4}$

Step-by-step explanation:

Fractions

They can be expressed as proper fractions, improper fractions or mixed numbers. Proper fractions are such that the numerator is less than the denominator, like 2/5, 7/11, -9/10. Improper fractions are those whose numerators are greater than the denominator, such as 5/3, 10/9, -21/8.

Mixed numbers are expressions made of whole numbers and a proper fraction, like 4 3/5, 1 1/2, -5 4/9. Mixed numbers can be transformed to improper fractions and vice-versa.

The question requires us to find the average change in field position on each run of the running back for the Bulldogs football team which carried the ball 5 times for a total loss of 11 1/4 yards.

The number 11 1/4 is mixed, to express it as an improper fraction, we add the numbers like

$\displaystyle 11+\frac{1}{4}=\frac{45}{4}$
