they cannot be perpendicular to a line because it is the shape of a right angle.

Answer: The term "perpendicular" means meeting or crossing at right angles. Lines, rays, line segments, and planes can be perpendicular.

Find percent -> 2nd month.

4264*.25==1066 phone calls+=4264

==5330 for 2nd month.

for 2nd -> 3rd

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

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

Either the first or the third choice is correct. We can't tell which one without seeing the rest of the words ... the ones that are cut out of the picture.

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: 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. ".
