Find
f '(a).
f(x) = 3 − 4x

Answer:

3(x+2) and 3x+6 are equivalent.

3(2x) is not.

Step-by-step explanation:

Simplify the expressions first.

1. 3(x+2) becomes 3x+6

2. 3x + 6

3. 3(2x) becomes 6x

The first and second are equivalent to each other.

The third one is not equivalent.

Answer:

$14.25

Step-by-step explanation:

First write 25% as a decimal by dividing by 100.

[tex]\frac{25}{100}[/tex] = .25

Now multiply the cost of the purse by the discount.

$19 x .25 = $4.75

That is the discount, now subtract the discount from the original price of the purse.

$19 - $4.75 = $14.25

Answer:

(5x - 1)(5x - 1) = 25x² - 10x + 1

Step-by-step explanation:

Let us solve the question step by step

We need to find the product of (5x - 1) and (5x - 1)

∵ 5 × 5 = 25

∵ x × x = [tex]x^{1+1}[/tex] ⇒ multiply same base means add their powers

∴ x × x = x²

∴ 5x × 5x = 25x²

∵ 5x × -1 = (5 × -1)x

∴ 5x × -1 = -5x

∵ -1 × 5x = (-1 × 5)x

∴ -1 × 5x = -5x

∵ -1 × -1 ⇒ (-)(-) = (+)

∴ -1 × -1 = 1

∵ (5x - 1)(5x - 1) = 25x² + -5x + -5x + 1

∵ -5x and -5x are like term, then add their coefficients

∵ -5x + -5x = (-5 + -5)x

∴ -5x + -5x = -10x

∴ (5x - 1)(5x - 1) = 25x² + -10x + 1

∵ (+)(-) = (-)

∴ (5x - 1)(5x - 1) = 25x² - 10x + 1

Answer:

y=4x-6

Step-by-step explanation:

The formula for y is -6+4x from the equation −4x+y=−6.

Two or more expressions with an Equal sign is called as Equation.

The given equation is −4x+y=−6

Minus four times of x plus y equal to minus six.

We need to solve the formula for y.

In the given equation x and y are the variables.

Isolate the variable y by add 4x on both sides of the equation

y=-6+4x

Hence, the formula for y is -6+4x from the equation −4x+y=−6.

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

From the question the point is (-1,-6) and slope 4

The equation of the line is

[tex]y + 6 = 4(x + 1) \\ y + 6 = 4x + 4 \\ y = 4x + 4 - 6[/tex]

We have the final answer as

Answer:

  20

Step-by-step explanation:

An equivalent decimal fraction is non-repeating if and only if the fraction denominator has a prime factorization consisting only of powers of 2 and 5.

Powers of 2 less than 300 are ...

  2, 4, 8, 16, 32, 64, 128, 256

Powers of 5 less than 300 are ...

  5, 25, 125

A fraction will have a finite decimal representation if its denominator is one of these numbers, or some product of these numbers.

Products would include ...

  10, 50, 250, 20, 100, 40, 200, 80, 160

The count of all of the listed numbers is ...

  8 powers of 2 + 3 powers of 5 + 9 powers of 2 and 5 = 20 listed numbers

There are 20 finite decimal fractions among the fractions 1/2 ... 1/300.

Answer:

-50

Step-by-step explanation:

Luckily for us this one is very simple.

(-5)(10) can also be written as [tex]-5*10[/tex] or with any other multiplicative operator (a symbol that represents multiplication). So this becomes very simple multiplication.

We know that when we multiply a positive number by a negative, the result will be negative - and we also know that 5 times 10 is 50. So our result will be: [tex](-5)(10) = -50[/tex]

The invested amount dogwood tree is $15000 and on maple tree is $45000 as per linear equation.

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."

Given, total invested amount is $60000.

Let, invested amount for dogwood trees is $x.

Therefore, invested amount for maple trees is ($60000 - x).

Now, the profit on a dogwood tree is 29% = 0.29.

The profit on a red maple tree is 17% = 0.17.

Again, the profit for the entire stock is 20%. = 0.20.

Therefore,

(x + x × 0.29) + [(60000 - x) + (60000 - x) × 0.17 = 60000 + 60000 × 0.20

⇒ 1.29x + 60000 - x + 10200 - 0.17x = 72000

⇒ 0.12x = 72000 - 60000 - 10200

⇒ 0.12 x = 1800

⇒ x = 15000

Therefore, invested amount  on dogwood tree is $15000.

Similarly, invested amount on maple tree is $(60000 - 15000) = $ 45000.

Answer:

This question is pretty simple, half the values given are just to confuse you

notice that we are given a function which gives us the height of the rock at any given time, so if we use that function for t=2 seconds, we will get the height of the rock after 2 seconds

We are given the function:

h(t) = -16t² - 50t + 220

replacing t with 2

h(2) = -16(2)² - 50(2) + 220

h(2) = -16(4) - 100 + 220

h(2) = -64 - 100 + 220

h(2) = 56 feet

Therefore, the height of the rock 2 seconds after throwing is 56 m

Answer:

There are no solutions   Hope this helped<3 :)

Step-by-step explanation:

Let's solve your equation step-by-step.

3(y+2)+y=4(y−1)+9

Step 1: Simplify both sides of the equation.

3(y+2)+y=4(y−1)+9

(3)(y)+(3)(2)+y=(4)(y)+(4)(−1)+9(Distribute)

3y+6+y=4y+−4+9

(3y+y)+(6)=(4y)+(−4+9)(Combine Like Terms)

4y+6=4y+5

4y+6=4y+5

Step 2: Subtract 4y from both sides.

4y+6−4y=4y+5−4y

6=5

Step 3: Subtract 6 from both sides.

6−6=5−6

0=−1

Answer:

There is no solution

Step-by-step explanation:

First step:  

3(y + 2) + y = 4(y – 1) +9

Second step, distributing:

3y + 6 +y  = 4y -4 + 9

Third step, combining like terms:

4y + 6 = 4y + 5

Fourth step:

determine if it has a solution which it does not. How do i know?

When you continue the problem 4y + 6 = 4y + 5 you need to subtract 6 on both sides which gets you -1. then you subtract 4y on both and you get

0=1. Therefore this is definitely no solution
