Step-by-step explanation:

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. ".

Step-by-step explanation:

Answer:

5,8

Step-by-step explanation:

since C is on y coordinate 8 if its a reflection C' will be as well and C is on x coordinate -5 so if its a reflection then C' will be 5 so 5,8

Answer:

(5,8)

Step-by-step explanation:

one way I like to do it is a) count how many squares C is away from the axis, which is 5, and then staring at the Y-axis count five spaces to the right, or b) which might be a little more time consuming, do where the original D is and see how many spaces up and across C is from D, which is up two and right 5. So then go to the new one, and go up two and instead of going right five, count five to the left because it's reflected. Hope that made sense and helped! If not please let me know and i'll try to explain further.

Answer:

12/25

Step-by-step explanation:

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:

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.

Step-by-step explanation:

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.

The top one is correct because ive done it.

Step-by-step explanation:

Answer:

80n + 20

Step-by-step explanation:

20 stays the same because it's a one time fee. Then, for every night the Harvey family stays, it costs them eighty dollars. So, it's 80n + 20

Answer: 80n+20

Step-by-step explanation:

80 is the cost of nights you stayed but you don’t know the number of nights they dated so you place n next to 80 and they payed an additional 20 fee so you add that to 80n

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:

The second option

Step-by-step explanation:

You just do 19.50/3 to get 6.50

$6.50 per shirt.

Solution

Since three shirts cost $19.50

1 would be $19.50÷3= 6.50
