In the equation, f(x)=2x-4(x+1), what is the value of f(-14)?
A. 32
B. -32
C. 5
D. 24
Answer:
D. 24
Step-by-step explanation:
Plug in -14 to the equation:
f(x) = 2x - 4(x + 1)
f(-14) = 2(-14) - 4(-14 + 1)
Simplify:
f(-14) = -28 - 4(-13)
f(-14) = -28 + 52
f(-14) = 24
So, D is the correct answer.

The length of one side of a shoebox is 8 centimeters more than twice the width. The base of the shoebox has an area of 72 square centimeter.
Write an equation to represent this situation with w representing the width in centimeter
Answer: [tex]w^2+4w-36=0[/tex]
Step-by-step explanation:
Let w = width of the base of the shoebox.
As per given ,
Length = 8+2w centimeters
Area of base = 72 square centimeter
Area of rectangle = Length x width
[tex]\Rightarrow\ 72=w(2w+8)\\\\\Rightarrow\ 72= 2w^2+8w\\\\\Rightarrow\ 2w^2+8w-72=0\\\\\Rightarrow\ w^2+4w-36=0[/tex]
Required equation: [tex]w^2+4w-36=0[/tex]

Step-by-step explanation:
The value of f(0) from the graph of f(x) is (a) 12 only
What are functions?Functions are used to represent graphs, equations, ordered pairs and relations.
To interpret the value of the function, we start by reading the graph.
From the graph, the value of the function when x = 0 is 12
This means that:
[tex]f(0) = 12[/tex]
Hence, the value of f(0) from the graph of f(x) is (a) 12 only

A restaurant starts with 10 dozen
pieces of cornbread. Every order
receives 2 piece of cornbread. At the
end of their lunch rush, there are 28
pieces of cornbread left. How many
orders did the restaurant take?
Answer:
48 orders
Step-by-step explanation:
so 10 dozen is 120 because 12(10) is 120. we first subtract 120-28, which is 96. divided 96 by 2 to get 48.
equation: (12(10)-28)/2=x
Answer:
46 orders.
Step-by-step explanation:
(10*12) - 2x = 28
120 - 2x = 28
-2x = 28 - 120
-2x = -92
x = -92/2
x = 46

alguien me puede ayudar por favor?:(
13y+12,6y−9=y
2 Switch sides.
y=13y+12,6y-9y=13y+12,6y−9
3 Break down the problem into these 2 equations.
y=13y+12y=13y+12
y=6y-9y=6y−9

i dont know what u said so i solved for y
Answer:
y = 1/4
Step-by-step explanation:
Yo no comprehendo espanol mucho, but I'll try
12y + 15 + y - 36y - 9 = y
Rearrange
12y + y (-y) + 15 (-15) - 36y - 9 (+9)= y (-y) (-15) (+9)
12y - 36y = - 15 + 9
-24y = - 6
Divide both sides by - 24 (Take note of the signs (+) (-))
-24y/-24 = - 6/-24
y= 1/4

The 7 is negative for me..You should maybe try yourself too and see what you get I might have made a mistake
Step-by-step explanation:
I'm guessing you live somewhere in the U.S. so I'll use the equation you use there
Equation:
[tex]y = mx + b[/tex]
[tex]m = \frac{y1 - y2}{x1 - x2} [/tex]
first pick two points
I'll pick (0,8) and (1,1)
[tex]m = \frac{8 - 1}{0 - 1} = \frac{7}{ - 1 } = - 7[/tex]
this means that the slope is -7
So far the equation will look like this
[tex]y = - 7x + b[/tex]
to get b pick one point, I'll pick (0,8) and replace y and x
[tex]8 = - 7 \times 0 + b[/tex]
when you solve this you'll get b
[tex]b = 8[/tex]
So the equation will look this
[tex]y = - 7x + 8[/tex]

What is the length of side AC
Answer:
7 Units.
Step-by-step explanation:
First of all, you could just count the units, but that's not really too effective. Otherwise, you could start from the coordinates of the "C" point, and see how it's at -Y = -5. Therefore, to get to the line separating the two points, you would have to subtract 5 from 5 to get to the line. Now, you look at point "A". It's Y coordinate is 2. Therefore, adding 5 and 2 together gives you 7 units.
20 points and brainiest for the correct answer
On a coordinate plane, a line goes through (0, negative 5) and (5, 0).
A system of equations consists of a line s of the equation y = x - 5 that is graphed in orange, and a line t that passes through the points (0, 2) and (8, -4). The equation of line t is y = -[tex]\frac{3}{4}[/tex]x + 2.

B. Equation =
Answer:
The friends split the bill at 15.32$
Step-by-step explanation:
So to find how much each paid you would take the bill total and divide it by the amount of people in this case three
And for the equation it would be 45.96/3=15.32$
The equation to model the solution to the problem would be; 3x = 45.96. the friends split the bill at 15.32 dollars.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be one degree.
Given that the dinner for Lorenzo and his 3 friends costs $45.96.
To determine how much each paid would take the bill total
Therefore, we will divide it by the number of people in this case three
3x = 45.96
x = 45.96/3
x = 15.32$
And for the equation would be; 3x = 45.96
