Answer:
f(-12) = -13
Step-by-step explanation:
f(x) = x - 1
Let x = -12
f(-12) = -12-1
= -13
Answer:
[tex]f(x) = x - 1 \\ f( - 12) = - 12 - 1 \\ \boxed{ f( - 12) = - 13}[/tex]

The width of a rectangular field is 20 centimeters. The perimeter is at least 648 centimeters. Write and solve an inequality to find the possible lengths of the field.
The possible length of the rectangular field as represented by an inequality is; l ⩾ 322 centimetres
The perimeter of a rectangular field is;.
Perimeter = (2 × length) + (2 × width)However; the perimeter of the field is at least 684 centimetres.
Therefore;

Each sheep has 4 legs and each chicken has 2 legs.if a farm boy counts 50 heads and 130 feet, how many sheep are there
Answer:
15 sheep
Step-by-step explanation:
1 leg = 1 foot
1 head = 1 animal
Suppose all the animals are chickens:
50 × 2 = 100
130 - 100 = 30
4 - 2 = 2
30 ÷ 2 = 15
Hence, there are 15 sheep.
Show all work to identify the asymptotes and zero of the function f of x equals 4 x over quantity x squared minus 16.
9514 1404 393
Answer:
asymptotes: x = ±4, y = 0zero: x = 0Step-by-step explanation:
The function factors as ...
[tex]f(x)=\dfrac{4x}{(x-4)(x+4)}[/tex]
The vertical asymptotes are found where the denominator factors are zero:
x-4 = 0 ⇒ x = 4
x+4 = 0 ⇒ x = -4
The zero of the function is where the numerator is zero:
4x = 0 ⇒ x = 0
The horizontal asymptote of the function is the value of 4x/x² when x tends to infinity. That value is zero. The equation of the horizontal asymptote is ...
y = 0
Quinn leaves her house at 10:00 am and runs 3 miles at a steady pace of 6 miles per
hour. She relaxes and takes a lunch break for 1 hour. She is pretty tired so she walks
home at a steady pace of 2 miles per hour. What time does Quinn return home
Using the relation between velocity, distance and time, it is found that Quinn returns home at 1 pm.
Velocity is distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex]
She walked 3 miles at a velocity of 6 miles per hour, thus [tex]d = 3, v = 6[/tex]. The time is:[tex]v = \frac{d}{t}[/tex]
[tex]t = \frac{d}{v} = \frac{3}{6} = 0.5[/tex]
Thus, she arrived at 10:30 am, and took a lunch break of 1 hour, so she started to return at 11:30 am.Distance of 3 miles, velocity of 2 miles per hour, thus [tex]d = 3, v = 2[/tex]. The time she took to return, in hours, is:[tex]t = \frac{d}{v} = \frac{3}{2} = 1.5[/tex]
1.5 hours after 11:30 am is 1 pm, thus, Quinn returns home at 1 pm.

Francis mixes 3/8 gal of white paint, 2 7/8 gal of blue paint, and 1 1/4 gal of red paint.
How much white paint will Francis need to make 7 gallons of the same color paint?
Francis has made _____ gal of paint when he first mixes the three colors.
The constant of proportionality of white paint to gallons of mixed paint is ______
Francis will need __________ gal of white paint to mix together 7 gals of the same color paint.
PLEASE HELP!!!!!
Blank one the options are: thirteen-fourths, thirty-one eights, or nine-halves.
Blank two the options are: one-seventh, one-twelfth, three twenty-sixths, or thirty-six thirds
Blank three the options are one, eighty-four, seven twelfths, or twenty-one twenty-sixths
Please help me with the problem.
List all the info:
3/8 gallon of white paint
2 7/8 gallon of blue paint
11/4 gallon of red paint
First, let’s answer the first question.
Francis has made _____ gal of paint when he first mixes the three colors.
Add all the gallons of paints together and you get 6. So, Francis has made 6 gal of paint when he first mixes the three colors.
Now for the second blank. All you have to do is do 6 divided by 3/8 which is 16. So, The constant of proportionality of white paint to gallons of mixed paint is 16.
Lastly, you will have to do is 3/8 x 7 = 2 5/8. (Im not too sure about this part though, but the rest I‘m pretty confident about)

im struggling with this :D i need help!
Answer:
not a real number
Step-by-step explanation:
any negative number under a square root sign, except for 0, isn't real
On evaluating the given roots,
(a) [tex]$-(\sqrt[3]{8}) = -2$[/tex]
(b) [tex]$\sqrt[4]{-81}$[/tex] is not a real number
(a) [tex]$-(\sqrt[3]{8})$[/tex]:
The cube root of 8 is the number that, when raised to the power of 3, equals 8. In this case, the cube root of 8 is 2, because [tex]2^3 = 8[/tex].
Since we have a negative sign in front of the cube root, the result will be the negative value of the cube root of 8.
Therefore, [tex]$-(\sqrt[3]{8}) = -2$[/tex].
(b) [tex]$\sqrt[4]{-81}$[/tex]:
The fourth root of a number is the number that, when raised to the power of 4, equals the given number.
In this case, we are looking for the fourth root of -81.
However, the fourth root of a negative number is not a real number. This is because raising a positive number to an even power (in this case, 4) will always result in a positive value, and there is no real number that, when raised to the power of 4, gives a negative result.
Therefore, the fourth root of -81 is not a real number.

Step-by-step explanation:
Standard form is a way of writing a number so it is easier to read. It is often used for very large or very small numbers. Standard form is like scientific notation and is typically used in science and engineering.--A number is written in standard form when it is represented as a decimal number times a power of 10.

4 gallons of low fat milk cost 1.80, Find the cost of 6 gallons of low fat milk.
Answer:
2.70
Step-by-step explanation:
4 gallons 1.80
2 gallons 0.90(half)
6 gallons 2.70(both above)
Answer:
$2.70
Step-by-step explanation:
Divide 1.80 by 4 = $45 Cents
( Check : 45 x 5 = 1.8) (* Add 0 )
So since it is now known that a gallon of low fat milks costs $45 cents per gallon, multiply 6 by 0.45 and you'll get 2.7
So it can be a type of currency,
add 0
So the reuslt would be $2.70
Therefore, the cost of 6 gallons of low fat milk is $2.70 ( 2 dollars and 70 cents).
