for 2nd -> 3rd

6396==5330*x, solve algebraically to get .20  == 20% increase from 2nd month to 3rd month.

Answer:

Statement false.

Statement true.

Step-by-step explanation:

The left hand side of the equation is not equal to the right hand side, the statement is false.

[tex]16\% \: of \: 250 \: = 0.16 \: \times \: 250 = 40[/tex]

[tex]16\% \: of \: 250 \: is \: equal \: to \: 250\% \: of \: 16[/tex]

The result of both statement is the same, the statement is true.

Answer:

x=3 and x=-1.25

Step-by-step explanation:

4x^2-7x=15

subtract 15 from each side:

4x^2-7x-15=0

factor  (trying different numbers that the sum is 7 and the quotient is 15)

(2x-6 )(2x+2.5 )=0

2x-6=0 add 6 to each side

2x=6

x=3

2x+2.5=0   subtract 2.5 from each side

2x=-2.5

x=-1.25

Answer:

Step-by-step explanation:

The function can be used to find p, the profit when c paintings are sold is p = 25x - c.

Given that, an artist spent $75 on supplies to create paintings.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Let the x be the number of paintings sold.

Now selling price of articles = $25x

Profit (p) = 25x - c

Hence, the function can be used to find p, the profit when c paintings are sold is p = 25x - c.

Answer:

Step-by-step explanation:

24 : 30 = 4 : 5

44 : 99 = 4 : 9

108 : 36 = 3 : 1

33 : 9 = 11 : 3

49 : 14 = 7 : 2

Answer:

y = x + 9 ( in years)

Step-by-step explanation:

Given that Patrick is x years old and his brother is 9 years older than he is. Then;

His brother's age will be

= x + 9

If his brother is y years old then

y = x + 9

Since y is the subject, y has been expressed in terms of x. Where y is the age of Patrick's brother and x is Patrick's age.

Answer: She read 242 pages last week.

Step-by-step explanation:

Total pages = 360

Let the number of pages she read last week = x

( Pages read last week) + (Pages read today) = [tex]\dfrac45[/tex] (Total pages)

i.e. [tex]x+46=\dfrac45(360)[/tex]

[tex]\Rightarrow x+46=288\\\\ \Rightarrow x= 288-46\\\\ \Rightarrow x=242[/tex]

Hence, she read 242 pages last week.

Answer:

3) [tex]all \: real \: numbers[/tex], [tex]( - \infty , \infty )[/tex], or [tex]- \infty \leqslant x \leqslant \infty[/tex] (same thing)

4) [tex] - \infty < y < 0[/tex] or [tex]( - \infty ,0)[/tex] (same thing)

5) [tex]-2[/tex] or [tex](0, -2)[/tex] (same thing)

Step-by-step explanation:

3) Domain represents the amount of [tex]x[/tex]-values in a function. The image shows that the function's arrows point in both directions (right and left), infinitely, so the domain would be [tex]all \: real \: numbers[/tex], [tex]( - \infty , \infty )[/tex], or [tex]- \infty \leqslant x \leqslant \infty [/tex](same thing).

4) Range represents the amount of [tex]y[/tex]-values in a function. The function goes downward forever ([tex] - \infty < y[/tex]) by the indication of an arrow and halts just under the y-axis ([tex]y < 0[/tex]). After combining these two inequalities, you see that the range is [tex] - \infty < y < 0[/tex] or [tex]( - \infty ,0)[/tex] (same thing).

5) The [tex]y[/tex]-intercept is where the function crosses the [tex]y[/tex]-axis. In this function, the [tex]y[/tex]-intercept is [tex]-2[/tex] or [tex](0, -2)[/tex] (same thing).

Answer:

p = k ^2 + 3 r

Step-by-step explanation:

The solution of the given equation k = √(p - 3r) for p will be p = k² + 3r.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

In another word, the equation must be constrained with some constraints.

As per the given equation,

k = √(p - 3r)

Square on both sides as,

k² = (√(p - 3r))²

k² = p - 3r

Add 3r on both sides as

k² + 3r = p - 3r + 3r

k² + 3r = p

Hence "The solution of the given equation k = √(p - 3r) for p will be p = k² + 3r. ".
