Mr. Lin writes the expressions
-20 - 8 and 8 - (-20) on the board.
He asks his class which result is greater. How can his class decide without finding
the value of each difference?
Answer:
Just see that the first expression has all negative, meaning the total will be a negative, but the second expression the subtraction sign and the negative sign are together, there's a rule when two negative sign's are together/next to each other, they turn into a addition sign, so it basically 8 + 20 for the second expression, so 8-(-20) has a higher result
Step-by-step explanation:
There's no work needed to be done :P
The first one will be all negative and the second one will be all positive
What is the sum of first k+1 even numbers
Answer:
[tex]Sum = (k+1)(k+2)[/tex]
Step-by-step explanation:
Given
k + 1 even numbers
Required
Their sum
This question will be solved using the sum of nth term of an AP
[tex]S_n = \frac{n}{2}(2a + (n - 1)d)[/tex]
Where
a = the first even number
[tex]a = 2[/tex]
n = number of terms
[tex]n =k +1[/tex]
d = difference between consecutive even numbers
[tex]d = 2[/tex]
So, the expression becomes:
[tex]Sum = \frac{k+1}{2}(2 * 2 + (k + 1 - 1) * 2)[/tex]
[tex]Sum = \frac{k+1}{2}(2 * 2 + (k) * 2)[/tex]
[tex]Sum = \frac{k+1}{2}(4 + 2k)[/tex]
[tex]Sum = \frac{(k+1)(4 + 2k)}{2}[/tex]
Factorize 4 + 2k
[tex]Sum = \frac{(k+1)*2*(2 + k)}{2}[/tex]
[tex]Sum = (k+1)*(2 + k)[/tex]
[tex]Sum = (k+1)*(k+2)[/tex]
[tex]Sum = (k+1)(k+2)[/tex]
2. What is the slope of the line that passes through the points M(-5,0) and N (6,8)?
Answer:
Hi how are you doing today Jasmine
The slope of the line that passes through the given points M(-5, 0) and N (6, 8) is [tex]\frac{8}{11}[/tex]
Given the following points:
Points on the x-axis = (-5, 6) Points on the y-axis = (0, 8)To calculate the slope of the line that passes through the given points M(-5, 0) and N (6, 8), we would use the following formula;
The slope of a line can be defined as the gradient of a line.
Hence, a slope is typically used to describe both the direction and steepness of an equation of a straight line.
Mathematically, the slope of a line is given by the following formula;
[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substituting the given points into the formula, we have;
[tex]Slope. \;m = \frac{8 - 0}{6 - [-5]}\\\\Slope. \;m = \frac{8}{11}\\\\Slope. \;m = \frac{8}{11}[/tex]

A drawing has a scale of 1:40 on the drawing a bedroom is a rectangle measuring 10 cm x 18 cm a kitchen has an actual area of 300,000 cm² which has the bigger actual area of the kitchen or the bedroom
Answer:
The kitchen has a bigger actual area than the bedroom
Step-by-step explanation:
Here, we want to know the compartment with the bigger area
Since the bedroom has a drawing measure of 1 to 40; compared to the actual measurement;
The real dimensions will be;
10 * 40 and 18 * 40
= 400 by 720
So, its area which is length * width will be;
400 cm * 720 cm = 288,000 cm^2
we can see that the kitchen with an area of 300,000 cm^2 is bigger than this area of the bedroom

A bookstore pays $28 for a copy of a
textbook. The bookstore sells the textbook
for $42. What is the percent markup on the
textbook?
F 14%
G 33%
H 50%
3 67%
Answer: H - 50%
Step-by-step explanation:
The percentage markup on the textbook on the given percentage will be 50%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of a textbook = $28
Selling price = $42
% markup = (42 - 28)/28 x 100 = 50%
Hence "The percentage markup on the textbook on the given percentage will be 50%".

Gino and Milla each open a savings account with an initial deposit of $6,300. Gino's account pays 2% simple interest annually. Milla's account pays 3% simple interest annually. If Gino and Milla make no other deposits or withdrawals, how much more interest will Milla's account earn than Gino's after 1 year?
Answer:
Milla's account would earn $63 more that Gino's account after 1 year.
Step-by-step explanation:
Both Gino and Milla made an initial deposit of $6300.
Principal = $6300
Gino's rate = 2% = 0.02
Milla's rate = 3% = 0.03
number of years = 1
Interest = Principal x Rate x Time
So that,
for Gino;
Interest = 6300 x 0.02 x 1
= 126
The interest on Gino's savings after a year is $126.
for Milla;
Interest = 6300 x 0.03 x 1
= 189
The interest on Milla's savings after a year is $189.
Milla's interest - Gino's interest = 189 - 126
= 63
Milla's account would earn $63 more that Gino's account after 1 year.

Sharon kicks a ball from the ground into the air with an upward velocity of 64 feet per second. The function h = -16t2 + 64t models the height h, in feet, of the ball at time t, in seconds. When will the ball reach the ground again?
Step-by-step explanation:
h = 64t - 16t².
When the ball reaches the ground, h = 0.
Therefore 64t - 16t² = 0, 16t(4 - t) = 0, t = 0 or t = 4.
Therefore the ball reaches the ground 'again' at t = 4.

Answer:
B The equation is 4x = -48. Ben's point total is -12.
Step-by-step explanation:
Ben's total + Olive's total = -48
x + 3x = -48
4x = -48
x = -48 ÷ 4
Ben's total (x) = -12
Answer:
D
Step-by-step explanation:
If the Olive's is 3 times x, this can be written as 3x. Ben's score is just x. Combine those to get the equation 4x=-48. Divide to get x=-12
