Answer:
slope = - [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (7, 12 ) and (x₂, y₂ ) = (19, - 4 )
m = [tex]\frac{-4-12}{19-7}[/tex] = [tex]\frac{-16}{12}[/tex] = - [tex]\frac{4}{3}[/tex]

The nearest cube to -12 is -8 ( -27 is the next after -12)
a) The answer is -2.
b) we can do this by trial and improvement
It must be between -2 and -3, closer to -2 than 3 so first we guess -2.1
(-2.1)^3 = -9.261
(-2.2)^3 = -10.648

What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
[tex]y = kx[/tex]
In which k is the constant of proportionality, also called slope.
In this problem, the points (number, cost) are: (3,39), (5,65) and (8,104), hence the slope is given by:
[tex]k = \frac{39}{3} = \frac{65}{5} = \frac{104}{8} = 13[/tex]
Hence, the equation is:
y = 13x.

The slope of the linear equation is $13 per necklace.
Linear equationA linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope (rate of change), and b is the y intercept (initial value of y).
Let y represent the total charge for x number of necklaces.
From the table, using (3, 39) and (8, 104), hence:
m = (104 - 39) / (8 - 3) = 13
The slope of the linear equation is $13 per necklace.

Answer: 6x^2+1
(very sorry if this is wrong lol)
Step-by-step explanation:
Substitute all the given numbers into the equation, by doing so this should give you 2x-1+3x+2+x^2.
Since we have a group of x’s add them together, which would make 6x^2, this leaves our -1 and +2 add these these two numbers together to make plus one and finally you will have 6x^2+1
Please explained that answer!
Answer:
f(x)= -1/2x+1
Step-by-step explanation:
The slope is negative because the graph goes up then to the left, making it negative. The slope is also 1 half because the slope is measured by rise over run. It rises once, then goes to the left twice. 1/2. It's also plus 1 because the graph cross the y-intercept at positive 1.
Solve for y,if 3+3y=1–13y
Step 1: Simplify both sides of the equation.
3+3y=1−13y−9
3+3y=1+−13y+−9
3y+3=(−13y)+(1+−9)(Combine Like Terms)
3y+3=−13y+−8
3y+3=−13y−8
Step 2: Add 13y to both sides.
3y+3+13y=−13y−8+13y
16y+3=−8
Step 3: Subtract 3 from both sides.
16y+3−3=−8−3
16y=−11
Step 4: Divide both sides by 16.
16y
16=−11/16
y=−11/16
Answer:
y=−11/16

What is the equation of the line in point slope form given a slope of -12 and a point of (-4,
-5)?
Answer:
The equation of a line in point-slope form is y-Y1=m(x-X1). ”m” is the slope and (X1,Y1) is a point.
So, the equation in point-slope form is y+5=12(x+4).

Write the expression as a power and evaluate it. 8*2^7
Answer:
1024
Step-by-step explanation:
The expression can be written as [tex]8 * 2^7[/tex]
What is power?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
Example: The standard form of the polynomial 5 + 2x + x² is expressed.
We shall first determine the polynomial's degree before expressing it in standard form.
The degree of the provided polynomial is two. Write the phrase containing the polynomial's degree.
Given:
8*2^7
The above expression can be written as
[tex]=8 * 2^7[/tex]
= 8 x 128
= 1024.
Hence, the expression can be written as [tex]8 * 2^7[/tex]

PLEASE HELP QUICK!! the cost of one litre of fuel in May 2015 was $0.88. this was a decrease of 20% on the cost in may 2014. calculate the cost of one litre of fuel in may 2014
Answer:
$1.1
Step-by-step explanation:
[tex] \frac{100}{price \: before \: \: decrease \: (x)} \: = \frac{100 - 20}{0.88} [/tex]
[tex] \frac{100}{x} = \frac{80}{0.88} [/tex]
Cross multiply
80x = 88
X = 88/80
X = 1.1
the cost of one liter of fuel in May 2014 was $1.10.
Let's denote the cost of one liter of fuel in May 2014 as "x" dollars.
According to the information given, the cost of one liter of fuel in May 2015 was a decrease of 20% on the cost in May 2014. This means that the cost in May 2015 was 80% of the cost in May 2014.
Mathematically, we can express this as:
Cost in May 2015 = (100% - 20%) * Cost in May 2014
0.88 = 0.8 * x
Now, let's solve for "x" (the cost in May 2014):
x = 0.88 / 0.8
x = 1.10
So, the cost of one liter of fuel in May 2014 was $1.10.

proves that the sum of
5 consecutive natural numbers is divisible by 5
Answer:
n = 5m + 10 = 5(m + 2), since m + 2 is an integer, then the n is divisible by 5.
Step-by-step explanation:
Answer:
Natural numbers are simply positive integers. For now, refer to the middle number (the third number), as x. Thus, the numbers are: x - 2, x - 1, x, x + 1, and x + 2. Simply add all these numbers to get 5x, a number that is divisible by 5. As such, you can conclude that any 5 consecutive numbers are divisible by 5, and the quotient would be the third, or middle number.
