Find f(-3) with given function f(x)=x²Given
Quadratic Function[tex]f(x) = {x}^{2} [/tex]
Step 1
Substitute x = -3 in the equation and replace f(x) to f(-3).[tex]f(x) = {x}^{2} \\ f( - 3) = {( - 3)}^{2}[/tex]

Answers
Answer:
(x, y) = (-8, 19)
Step-by-step explanation:
9x + 3y = -15
-4x - 3y = -25
(9x + 3y) + ((-4x) - 3y) = -15 + (-25)
5x = -40
x = -8.
So,
9x + 3y = -15
9 * (-8) + 3y = -15
-72 + 3y = -15
3y = 57
y = 19

Answers
Answer:
constant monomial
Step-by-step explanation:
The polynomial, 9, has 1 term and its degree is 0. Therefore, the polynomial is a constant monomial.
The given expression is a constant monomial. Therefore, option A is the correct answer.
What is the polynomial?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.
Here given expression is 9.
A constant monomial is a term with only a constant number. There is no variable in a constant monomial.
So, 9 is a constant monomial.
The given expression is a constant monomial. Therefore, option A is the correct answer.

Answers
Answer:
n= 12
Step-by-step explanation:
27=15+n
step 1. simplify
27=n+15
step 2. flip the equation n+15=27
step 3. subtract 15 from both sides
n+ 15 - 15 = 27 - 15 =
n=12
Answer:
12.
Step-by-step explanation:
We don't have the other number, so we must do the reverse operation, which is subtraction. So we have to subtract 27 from 15. 7-5 is 2, and 20-10 is 10. Add those together and you get 12.
To make 3 dinner rolls, 34 cup of flour is used. How many rolls can you make with 212 cups of flour?
Answers
Answer:
If 34 cups of flour was use to make 3dinner rolls. . To get the amount of cup which will make a dinner roll divide 34/3=11 approximately. So if 11.3 cups give us 1 dinner roll. To get how many dinner rolls 212 cups of flour divide 212/11.3=18.8 approximately. Or divide 212/34*3=18.8 approximately

The perimeter of a rectangular field that measures 2 feet by 18 inches is _________ ft.
Answers
P= (2+2ft) + (18+18in)
P= 4ft + 36in
12in = 1 ft
36in = 3ft
4ft + 3ft = 7ft
Answer:
7 ft
Step-by-step explanation:
As we know that the formula to find the perimeter of a rectangle is
P = 2 (l) + 2(w). With that being said, we can look at the question.
The answer should be given in terms of feet, so we will have to convert 18 inches to ft. In order to convert from inches to ft, you will have to divide by 12.
18 / 12 = 1.5ft
18 inches = 1.5 foot
Now we take the given values and put them into the formula to find the perimeter of the rectangular field.
2 (l) + 2(w) = 2 (2 ) + 2 (1.5) = 7ft
The perimeter of the rectangular field is 7ft.

Using the linear equation, predict the average height for a two-year old.

D. 35 inches
Answers
Answer:
(a) [tex]y = 4.5x + 22[/tex] -- The equation
(b) 31 inches
Step-by-step explanation:
Given
See attachment
Solving (a): The equation of the trend line.
We start by calculating the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (0,22)[/tex]
[tex](x_2,y_2) = (4,40)[/tex]
So, we have:
[tex]m = \frac{40 - 22}{4 - 0}[/tex]
[tex]m = \frac{18}{4}[/tex]
[tex]m = 4.5[/tex]
The equation is then calculated using:
[tex]y = m(x-x_1)+y_1[/tex]
Where:
[tex](x_1,y_1) = (0,22)[/tex]
[tex]m = 4.5[/tex]
[tex]y = 4.5(x - 0) + 22[/tex]
Open bracket
[tex]y = 4.5x - 0 + 22[/tex]
[tex]y = 4.5x + 22[/tex]
(b) The height of a 2 year old.
To do this, we substitute 2 for x in [tex]y = 4.5x + 22[/tex]
[tex]y = 4.5 * 2 + 22[/tex]
[tex]y = 9+ 22[/tex]
[tex]y = 31[/tex]
The prediction is 31 inches
Parallelogram A B C D is shown. The length of A B is (9 x minus 14) inches and the length of D C is (3 x + 4) inches. In parallelogram ABCD, what is DC? 3 in. 9 in. 13 in. 19 in.
Answers
Given:
In a parallelogram ABCD, AB=(9x-14) inches and DC=(3x+4) inches.
To find:
The measure of DC.
Solution:
We know that opposite sides of a parallelogram are equal.
In the parallelogram ABCD, AB and DC are opposite sides. So,
[tex]AB=DC[/tex]
[tex]9x-14=3x+4[/tex]
[tex]9x-3x=14+4[/tex]
[tex]6x=18[/tex]
Divide both sides by 6.
[tex]x=\dfrac{18}{6}[/tex]
[tex]x=3[/tex]
Now,
[tex]DC=3x+4[/tex] inches
[tex]DC=3(3)+4[/tex] inches
[tex]DC=9+4[/tex] inches
[tex]DC=13[/tex] inches
The measure of DC is 13 in.
Therefore, the correct option is C.
Answer:
13in
