How to evaluate the function at the given value?The equation of the function is given as
f(x) = -8x + 20
The function to calculate is given as
5 - 2[f(-1)]
So, we start by calculating the value of the function at x = -1
This is represented as 'f(-1)
So, we have the following equation
f(-1) = -8(-1) + 20
Evaluate the product
So, we have the following equation
f(-1) = 8 + 20
Evaluate the sum
So, we have the following equation
f(-1) = 28
Substitute f(-1) = 28 in the expression 5 - 2[f(-1)]
So, we have
5 - 2[f(-1)] = 5 - 2 x 28
Evaluate the product
5 - 2[f(-1)] = 5 - 56
Evaluate the difference
5 - 2[f(-1)] = -51

Given m<7=107 and m<4= (8x+1) what is the value of x?
The value of x comes out to be 9.
Here, we are given that m∠7 = 107 and m∠4 = (8x+1)
From the figure given below, we can see that angle 7 and angle 6 are vertically opposite angles. Thus-
angle 7 = angle 6
measure of angle 6 = 107°
Now, angle 6 and angle 4 are opposite interior angles and the sum of opposite interior angles is equal to 180. Thus-
m∠4 + m∠6 = 180
8x + 1 + 107 = 180
8x + 108 = 180
8x = 180 - 108
8x = 72
x = 72/8
x = 9
Thus, the value of x comes out to be 9.

Mia has 12 boxes of chocolate chip cookies and 24 boxes of sugar cookies. Each box of chocolate chip cookies has 36 cookies. Each box of sugar cookies has 84 cookies. Mia says she has about 1,800 cookies in all. Is her answer reasonable? Explain.
Yes, because (12 x 20) + (40 x 80) = 3,400
Yes, because (12 x 80) + (40 x 40) = 2,560
No, because (12 x 40) + (20 x 80) = 2,080
No, because (12 x 80) + (20 x 40) = 1,760
Answer:
The answer given by Mia is not reasonable cause, when we sum up the data given by her we will conclude that the expression should be like (12*36) + (24*84) = 1800.
Step-by-step explanation:
Mia has 12 boxes of chocolate chip cookies and 24 boxes of sugar cookies.
Each box of chocolate chip cookies has 36 cookies.
Each box of sugar cookies has 84 cookies.
So, the total number of chocolate chips cookies will be = 12 * 36 ----(i)
And the total number of sugar cookies will be = 24 * 84 -----(ii)
As Mia says she has about 1,800 cookies in all.
So, we can write (i) and (ii) combined as,
(12*36) + (24*84) = 1800
The answer given by Mia is not reasonable cause, when we sum up the data given by her we will conclude that the expression should be like (12*36) + (24*84) = 1800.
Explanation: No, her answer is not reasonable.
Step by Step solution:
According to the given information, Mia has 12 boxes of chocolate chip cookies and 24 boxes of sugar cookies.
Now, each box of chocolate chip cookies has 36 cookies which means she has (36 × 12) = 432 chocolate chip cookies in total, using the unitary method.
Also, each box of sugar cookies has 84 cookies which means she has (84 × 24) = 1008 sugar cookies in total, using the unitary method.
Mia will then have with her in total of [(36 × 12) + (84 × 24)] = 1440 cookies.
It is an incorrect fact that Mia says that she has about 1800 cookies in total.
Hence, Mia has 1440 cookies in total.

Which transformations are needed to transform the graph of f(x) to the graph of g(x)?
Select EACH correct answer.
A. Horizontal translation 1 units right.
B. Horizontal translation 3 units right.
C. Vertical translation 3 units down.
D. Vertical translation 1 unit down.
E. Horizontal translation 1 unit left.
F. Vertical translation 3 units up.
We can see that function g(x) is a translation of one unit to the left and 3 units downwards of f(x), thus, the correct options are:
C and E.
What transformations are applied to the function f(x)?Here we have the two functions:
f(x)
g(x) = 4^(x + 1) - 3
And we know that g(x) is a translation of f(x)
Remember that the translations works as follows:
Vertical translation of N units:
g(x) = f(x) + N
If N > 0, the translation is upwards.
If N < 0, the translation is downwards.
Horizontall translation of N units:
g(x) = f(x) + N
If N > 0, the translation is to the left
If N < 0, the translation is to the right.
In this case, we can write g(x) as:
g(x) = f(x + 1) - 3 = 4^(x + 1) - 3
So we will have a translation of one unit to the left and 3 units downwards.

Prove that the opposite angles of a parallelogram are equal.
The opposite angles of a parallelogram are equal.
x + y = a+ b
Let's consider a quadrilateral ABCD which is a parallelogram with AC as its diagonal.
We know, in parallelograms opposites' sides are parallel.
So, AB∥DC and AD∥BC
Since AB is parallel to DC and AC is the transversal.
By alternate angles,
∠BAC = ∠DCA
y = a -----------------(1)
Similarly, AD is parallel to BC and AC is the transversal.
The alternate angles,
∠DAC = ∠BCA
x = b -----------------(2)
Adding equations ( 1 ) and ( 2 ),
∠BAC + ∠DAC = ∠DCA + ∠BCA
∠BAD = ∠DCB
x + y = a + b
Similarly, we can prove, ∠ADC=∠ABC
Hence proved, opposite sites of a parallelogram are equal.

Total of 10 and $ total of $0.85. The place value denotes a word, whereas the total value denotes a figure. In mathematics, ten numbers are known as symbols or digits.
What is meant by Summation?The sum of the digit and its place value is the total value. Example 1: In the number 58439, what is the place value of digit 4? As a result, digit 4's place value is Hundreds. Market capitalization is the value of a company as determined by the stock market. It is defined as the sum of all outstanding shares' market values. Multiply the number of outstanding shares by the current market value of one share to calculate a company's market cap.
Therefore,
a # total of 10
a $ total of $0.85
· Since we have 2 unknowns, we need to set up a System of 2 Equations.
· A System of 2 Equations helps us solve a situation with 2 Unknowns.
Let's set up our 2 equations for # and $.
· For the # equation:
Let n = # of nickels
Let d = # of dimes
So, n + d = 10
· For the $ equation, we have to assign a "value" to each of the coins:
A nickel is worth 5 cents or $0.05
A dime is worth 10 cents or $0.10
· They told us we have 5 cents, a specific # of times + 10 cents, a certain # of times, that = $0.85
So, $0.05n + $0.10d
= $0.85
To solve this, we have to have just 1 unknown, meaning just 1 variable.
· We represent one of the variables in terms of the other. But, which one?
· Well, since they are asking for # of dimes, let's define a nickel in the duration of a dime.
· Let's apply this in the simpler # equation:
So, n + d = 10
becomes n = 10 - d
· So now, in our $ equation, we can just replace "n" with "10 - d", and then solve for d, which is the # of dimes!
$0.05n + $0.10d = $0.85
$0.05(10-d) + $0.10d = $0.85
$0.5 - $0.05d + $0.10d = $0.85
$0.50 + $0.05d = $0.85
$0.05d = $0.35
d = 7
Check this with the # equation:
n + d = 10
n + 7 = 10
n = 3
Does that make sense? Let's see:
3 nickels + 7 dimes = $0.85 ?
3($0.05) + 7($0.10) = $0.85
$0.15 + $0.70 = $0.85
$0.85 = $0.85

⇒ 21y - 1 = 48x - 152x + 207x - 874

a) The volume of the cube is 27,271 cubic centimeter
b) The surface area of the cube is 5,400
Well the edge is 30 cm +- 0.1 cm
Volume will be side cubed, so max estimate for volume is (30.1)^3, and minimum (29.9)^3
So percentage error = [(30.1)^3 - 30^3/ / 30^3 x 100 = 1,00 %
Surface area is 6 x side squared
So max estimate for area is 6 x 30.1^2,
