Is 3 a solution to 4x - 3<5?

Answers

Answer:

To solve this

4x-3<5

4x<5+3

4x<8

x<8/4

x<2

so no, three is not a solution

Step-by-step explanation:

Answer: No

Step-by-step explanation:

X = 3

Replace the variable X with 3

4 x 3 - 3 (less than or equal to) 5

4 x 3 = 12 - 3 = 9

9 is not equal to or less than 5, thus 3 is NOT a solution

f(x)=x2−4x, find f(−3)

Answers

Answer:

f(-3) = 21

Step-by-step explanation:

To solve this, you can replace all x's with -3 and then solve to find the answer.

f(x) = x^2 - 4x

f(-3) = -3^2 - 4(-3)

f(-3) = 9 - (-12)

f(-3) = 21

12x 5 =(4x 2 )(C)12, x, start superscript, 5, end superscript, equals, left parenthesis, 4, x, squared, right parenthesis, left parenthesis, C, right parenthesis C=

Answers

Answer:

3x³

Step-by-step explanation:

Given the expression

12x^5 =(4x^2 )(C)

We are to find the value of C

Rewriting the equation will give;

(4×3)x²•x³ = 4x²C

4x²•3x³ = 4x²C

Divide both sides by 4x²

4x²•3x³/4x² = 4x²C/4x²

3x³= C

Hence the function C is 3x³

HELP ILY A tree is 4 1/2 feet tall. It is expected to grow by 1 3/4
feet per year.
At this growth rate, how many years will it take for the tree to have a height greater than 40 feet? Enter the answer in the box.
years

Answers

Answer:

It will take 21 years.

Step-by-step explanation:

First, find what x would be for it to equal 40 feet. This can be done with the equation 4.5 + 1.75x = 40.

4.5 + 1.75x = 40

Subtract 4.5 from both sides. This cancels out the +4.5.

1.75x = 40 - 4.5

Subtract 4.5 from 40 to get 35.5.

1.75x = 35.5

Divide both sides by 1.75. This cancels out the *1.75.

x = 35.5/1.75

Expand 35.5/1.75 by multiply both the numerator and denominator by 100.

x = 3550/175

Reduce 3550/175 by canceling out 25.

x = 142/7 = 20 2/7

Go up by one from 20 to get the answer of 21 years.
