Answer:

Step-by-step explanation:

it is like 9x9=81

but yeah like he said it is a square so all sides are the same

but that is if you want to find the parameter

this question is talking about area

so when a question gives you an area you ask yourself what can be multiplied by what in order to give me the area

or since all sides are the same like he said you could just do simple division and do 81/9 which will =9

and since the question mentions that the area is in square inches it is obvious that the answer would be put in inches

answer: 9 inches

If 225 people are split into 9 equal groups each group will have 25 members in it

Answer:

Y-intercept=(0, 2)

X-intercepts=(-4,0) & (-2,0)

Step-by-step explanation:

X and y- intercepts are determined when they pass through either the x or y axis. If the line passes through the x axis it is the x-intercept and vice versa for y.

Hope this helped.

Answer:

D) [0, ~)

Step-by-step explanation:

Domain of a Function:

the domain of a function is the set of values of x, the independent variable, that are responsible for the graph of the function.

For Example:

suppose, we have a function:

f(x) = 3x - 1

and it's domain is {1, 2, 3}

that means, the corresponding value of f(x) to these 3 values of x will be DEFINED, I.e., they exist and can be plotted on a graph.

The given function:

Therefore, for the given function, it's domain will be those values of x(the ones plotted on the horizontal line), that give some value to the function ,i.e., for which we can draw it's graph.

and since the graph starts from x = 0 and continues towards infiinity

(the arrow on the curve shows that the graph continues and hasn't yet come to a stop.)

So, that way we got [0, ~). ^^

Answer:

  2x -3y = 21

Step-by-step explanation:

The perpendicular line will have an equation with the x- and y-coefficients swapped and one of them negated. The constant will be the value that makes the equation true at the given point.

  3x +2y = 6 . . . . . given equation

  2x -3y = c . . . . . . coefficients swapped, one negated

  2(6) -3(-3) = c = 21 . . . . . the value of c for the given point

The desired equation is ...

  2x -3y = 21

the first answer would be 5 the second is 10 and the last one is 110

Answer:

x ≤14.5

Step-by-step explanation:

4x+16≤74

Subtract 16 from the 74 and that gives you 58

Then divide each side by 4. 58/4=14.5

Hope this helps! sry if I get it wrong! :(

Answer: x ≤ 29/2

Explanation:

Subtract 16 from both sides

4x + 16 - 16 ≤ 74 -16

Simplify

4x ≤ 58

Divide both sides by 4

4x/4 ≤ 58/4

Simplify

x ≤ 29/2

Answer:

  (a)  f(3) < g(3)

Step-by-step explanation:

Put the number where the variable is and do the arithmetic.

  f(3) = 4·3³ = 4·27 = 108

  g(3) = 3·4³ = 3·64 = 192

  108 < 192

  f(3) < g(3)

Answer:

110 dollars.

Step-by-step explanation:

Since every day you owe him 2 dollars more, and its been 25 days, 25 x 2 is 50.

You originally owed him 60, and 50 dollars in late fees, so 60 + 50 = 110.

You owe him 110 dollars.

Answer:

p = 7

Step-by-step explanation:

i think there's a proper equation to solve these kinds of problems but you can think about numbers times 6 (1x6 = 6, 2x6 = 12, 3x6 = 18,...)

The value of p will be 7.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

p is a whole number.

And, 6p is greater than 40 and less than 45.

Now,

Since, 6p is greater than 40 and less than 45.

Hence, We can formulate;

⇒ 40 < 6p < 45

Solve for p as;

⇒ 40 < 6p < 45

Divide by 6, we get;

⇒ 40/6 < 6p/6 < 45/6

⇒ 6.67 < p < 7.5

Since, p is a whole number.

Hence, The value of p = 7

Thus, The value of p will be 7.

Answer:

(13,-6)

Step-by-step explanation:

If you are at (-3,5) and you translate T to give you (6,-8), that means you translated (9,-13) because you moved right 9 units in the positive x direction and down 13 units in the negative y direction.

Apply this translation T to (4,7) and you get (13,-6).

Answer:

(13,  -6)

Step-by-step explanation:

Firstly, we need to find the translation. This can be achieved by calculating the amount the x and y coordinate shifts. Simply use the following equation:

[tex](x2 - x1, y2 - y1)[/tex]

Where x1 and y1 are the coordinates of the first set and x2 and y2 are the second. Plug the variables in:

[tex](6 - (-3), -8 - 5)\\(9, -13)[/tex]

So the x coordinate is shifted 9 positively and the y coordinate is shifted 13 negatively.

To calculate the new translation of the new point, add the translation onto the given coordinates:

[tex]( 4 + 9, 7 + (-13) )\\(13, -6)[/tex]

So the new point is (13,  -6).

Hope this helps!
