Model -4 + -2 using counter chipsRed chip = 1 Yellow chip = 1What’s the sum?
Given the following question:
Since both are negatives and we are adding the two together:
We need 4 red chips to represent the negative four (-4)
We need 2 more red chips to present the negative two (-2)
The total sum of -4 + -2 is...
[tex]-4+-2=-6[/tex]To represent the sum using the chips we will place "six red chips."
Point M is the midpoint of segment AB. If the coordinates of Mare (2, 8) and the coordinates of Aare (10, 12), find the coordinates of B.B(x, y) =(
Using the formula
[tex](x_{m\text{ , }}y_m)\text{ = (}\frac{x_1+x_2}{2}\text{ , }\frac{y_1+y_2}{2})[/tex]x₁= 10 y₁=12 Xm=2 Ym = 8
x₂ = ? y₂=?
Substituting and solving for x₂
[tex]x_m=\frac{x_1+x_2}{2}[/tex][tex]2\text{ = }\frac{10+x_2}{2}[/tex]Multiply both-side of the equation by 2
4 = 10 + x₂
subtract 10 from both-side of the equation
-6 = x₂
x₂= -6
Similarly, substituting and solving for y₂
[tex]y_m=\frac{y_1+y_2}{2}[/tex][tex]8=\frac{12+y_2}{2}[/tex]Multiply both-side of the equation by 2
16 = 12 + y₂
Subtract 12 from both-side of the equation
4 = y₂
y₂= 2
Hence; coordinates of B are;
B(x,y) = ( -6, 2)
(F.LE.5) The function f(x) = 7.75x models the amount of money that Jimearns for each hour of work. What does the lack of a constant tell us?A. There is no initial amount of money he gets paid prior to startingB. His hourly wageC. His total amount he gets paid for the dayD. The number of hours Jim has worked
In a linear model:
[tex]f(x)=mx+b[/tex]The coefficient of x, which is m, is the rate of change of the function f with respect to changes in the value of x. In the context of the problem, the coefficient of x tells us the amount of money that Jim earns per hour.
The constant term b is the initial value of the function f when x=0.
Since the given linear model has no constant term, it means that the initial value is 0. In other words, Jim will earn $0 if he works 0 hours.
Therefore, the correct choice is Option A) There is no initial amount of money he gets paid prior to starting.

The value of 'y' for the parallel line drawn by the Amir is 25°.
Describe the term transversal?A transversal would be any line which intersects 2 straight lines at different point in geometry. In geometry, a transversal line connects two lines within the same plane at 2 separate points. Transversals contribute to the parallelism of two or more additional straight lines inside the Euclidean plane.For the given question;
There are two parallel line cut by the transversal drawn by the Amir.
Thus, the relation of the two angles are-
The supplement angle of (4y - 45) is 180 - (4y - 45).
And,
180 - (4y - 45) = y (vertical angles)
Simplify the equation;
180 - 4y + 45 = y
5y = 125
y = 25°
Thus, value of 'y' for the parallel line drawn by the Amir is y = 25°.

yson does 75 sit-ups during his work out. He wants to increase his sit-ups by 15%. Which represents the new amount of sit-up
Answer:
he does 86 sit ups instead of 75 to increase by 15 percent
Step-by-step explanation:
Answer: The correct answer is 86.25 sit-ups (or round-up to 87 whole sit-ups).
Step-by-step explanation:
S = current amount of sit-ups (75)
S2 = Increased amount of sit-ups by 15%
The equation:
S2 = S + (S x .15)
S2 = 75 + (75 x .15)
S2 = 75 + 11.25
S2 = 86.25 sit-ups

Problem
You have $20,000 that you want to deposit into a savings account.
You have four options to choose from, Bank A offers 4.25% compounded monthly, (Ex 2) Bank B offers 6% compounded Semi Annually, (Ex 2) Bank C offers a simple interest account with a 5.5% rate, (Chapter 8.3) Bank D offers a rate of 4% compounded continuously. (Ex 3) How much money will you have in each account if you let the money sit for 5 years? Which is the best choice?
Solution
For this case we need to take in count the compound interest formula given by:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]Where P= 20000, r= interest rate in fraction and n= number of times that the rate is compounded in a year, t= 5 years and A is the future value
And the simple interest formula:
[tex]A=P(1+rt)[/tex]And compound continuosly:
[tex]A=\text{Pe\textasciicircum{}rt}[/tex]Let's calculate the final amount for each case
Bank A
[tex]A=20000(1+\frac{0.0425}{12})^{12\cdot5}=24726.038[/tex]Bank B
[tex]A=20000(1+\frac{0.06}{2})^{2\cdot5}=26878.328[/tex]Bank C
[tex]A=20000(1+0.055\cdot5)=25500[/tex]Bank D
[tex]A=20000e^{0.04\cdot5}=24428.055[/tex]And the best choice for this case seems to be Bank B since we will have more money at the end of the 5 year

Draw the given angles in standard position. 110 degrees, - 80 degrees
Standard Position of Angles
An angle is in standard position if its vertex is located at the origin and one ray is on the positive x-axis.
The ray on the x-axis is called the initial side and the other ray is called the terminal side.
Positive angles are measured counterclockwise, negative angles are measured clockwise.
The angle of 110 degrees is positive so it must be measured counterclockwise. The angle -80 will be drawn clockwise.
The following image shows the required angles:

Jamir is training for a race and is running laps around a field. If the distance around the field is 450 yards,how many complete laps would he need to do to run at least 4 miles?laps
We have that Jamir is training for a race and is running laps around a field:
• The distance around the field is 450 yards (per lap).
,• He needs to run at least 4 miles.
1. Now we can proceed as follows to find the number of laps Jamir needs to run as follows:
[tex]\begin{gathered} 1\text{ Mile}=1760.0065617yards \\ \\ 4\text{ Miles=}4(1760.0065617yards)=7040.0262468yards \end{gathered}[/tex]Then we have that Jamir needs to run about 7040.0262468 yards.
2. Since the distance around the field is 450 yards (per lap), then we have:
[tex]7040.0262468yards*\frac{1lap}{450yards}=15.6445027707laps[/tex]Therefore, in summary, Jamir needs to run about 15.64 laps to run at least 4 miles (almost 16 laps - if we round the result to the nearest whole number).
