Use the graph or table to write a linear function that relates y to x
An example for #5 is y=-8x+2, and an answer for 6. is y=6x+9. The formula is y=mx+b so the b is the y-int/y and the m is the slope/x. The x is the variable(the one beside the m).

Alexandra and Chi compete in an Olympic-type triathlon consisting of a 1.5 km swim, a 40 km bicycle ride, and a 10 km run. There are two transitions in the race where the participants take time to change from one mode of the race to another. Their times from the race are shown. Complete questions 1dash4 below.
How long does it take Alexandra to complete the triathlon. Write a linear equation to model total time t in hours.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
SWIM:
Alexandra __5km/hr
Chi _______ 6km/hr
Transition 1:
Alexandra __ 4 minutes
Chi _______ 5 minutes
CYCLE:
Alexandra __15km/hr
Chi _______ 15km/hr
Transition 2:
Alexandra __ 3 minutes
Chi _______ 5 minutes
RUN:
Alexandra __6km/hr
Chi _______ 7.5km/hr
Distances:
swim distance = 1.5km
bicycle ride distance = 40km
run distance = 10km
Time taken by Alexandra :
time = distance / speed
Swim time = 1.5km / 5km/hr = 0.3 hr
Transition 1 = 4/60 = 0.067 hr
Cycle time = 40km / 15km/hr = 2.67 hours
Transition 2 = 3/60 = 0.05 hr
Run time = 10 / 6km/hr = 1.67 hrs
Total time(t) in hours taken by Alexandra :
(0.3 + 0.067 + 2.67 + 0.05 + 1.67) hrs = 4.757 hours
Time taken by Chi :
time = distance / speed
Swim time = 1.5km / 6km/hr = 0.25 hr
Transition 1 = 5/60 = 0.083 hr
Cycle time = 40km / 15km/hr = 2.67 hours
Transition 2 = 5/60 = 0.083 hr
Run time = 10 / 7.5km/hr = 1.33 hrs
Total time(t) in hours taken by Chi
(0.25 + 0.083 + 2.67 + 0.083 + 1.33) hrs = 4.757 hours = 4.416 hours

Nicole accepted a new job at a company with a contract guaranteeing annual raises. In the first year, Nicole's salary will be $100000 and after working for the company for 5 years, she will have a salary of $110000. Write an equation for S,S, in terms of n,n, representing Nicole's salary after working nn years for the company.
Answer:
S=2000n+100000
Step-by-step explanation:
Since Nicole will have a salary of $110000 after working 5 years for the company, we know that S = 110000 when n = 5.
Find the slope using the two points.
110000 - 100000 10000
m = ------------------------ = ---------- = 2000
5-0 2
The slope shows how much the salary increases each year, which is the same thing as saying that Nicole got a raise of $2000 every year.

the area of the surface of this design is 31 in long
Answer:
392 inches²
Step-by-step explanation:
10 inches × 6 inches = 60 inches²
60 inches² × 2 = 120 inches²
----------------------------------------------------------------------------------------------------------
(6 inches + 4 inches) × 6 inches = 10 inches × 6 inches = 60 inches²
60 inches² × 2 = 120 inches²
----------------------------------------------------------------------------------------------------------
(10 inches × 6 inches) + (4 inches × 4 inches) = 60 inches² + 16 inches² = 76 inches²
76 inches² × 2 = 152 inches²
----------------------------------------------------------------------------------------------------------
Add them all together ~
120 inches² + 120 inches² + 152 inches² = 392 inches²

A triangle has vertices (1,4), (1,-2), and (-3,-2). what is the approximate perimeter of the triangle
Answer:
Perimeter of Traingle is 10 + 2√5[tex]\\[/tex]
Step-by-step explanation:
Let,
A = (1,4)B = (1,-2) C = (-3,-2)[tex]\\[/tex]
To find the perimeter of the traingele with vertices of A (1,4), B(1, -2) and C(-3,-2). We have to first find the distance between each pair of points, which will give length of the sides.
[tex]\\[/tex]
Using distance formula,
[tex]\\[/tex]
[tex] \dashrightarrow \sf \: \: AB = \sqrt{( x_{2} - x_{1})^2 + (y_{2} - y_{1})^2} \\ \\ [/tex]
[tex] \dashrightarrow \sf \: \: AB = \sqrt{{ {(1 - 1)}^{2} } + {( - 2 - 4)}^{2} } \\ \\ [/tex]
[tex] \dashrightarrow \sf \: \: AB = \sqrt{0 + {( - 6)}^{2} } \\ \\ [/tex]
[tex] \dashrightarrow \sf \: \: AB = \sqrt{36} \\ \\ [/tex]
[tex]\pink{ \dashrightarrow\sf \: \: {\underline{AB = 6 }}}\\ \\ \\ [/tex]
[tex] \dashrightarrow \sf \: \: BC = \sqrt{{ {( - 3 - 1)}^{2} } + {( - 2 + 2)}^{2} } \\ \\ [/tex]
[tex] \dashrightarrow \sf \: \:BC = \sqrt{ {( - 4)}^{2} + 0} \\ \\ [/tex]
[tex] \dashrightarrow \sf \: \:BC = \sqrt{16} \\ \\ [/tex]
[tex] \pink{ \dashrightarrow \sf \: \:{ \underline{ BC = 4 }}}\\ \\ \\ [/tex]
[tex]{\dashrightarrow { \sf \: \: {AC = \sqrt{{ {( - 3 - 1)}^{2} } + {(2 - 4)}^{2}}}} } \\ \\ [/tex]
[tex] \dashrightarrow \sf \: \:AC = \sqrt{ {( - 4)}^{2} + {( - 2)}^{2} } \\ \\ [/tex]
[tex] \dashrightarrow\sf \: \: AC = \sqrt{16 + 4} \\ \\ [/tex]
[tex] \dashrightarrow \sf \: \:AC = \sqrt{20} \\ \\ [/tex]
[tex] \pink{ \dashrightarrow \sf \: \: { \underline{AC = 2 \sqrt{5} }}}[/tex]
[tex]\\[/tex]
Now,
[tex]\\[/tex]
[tex] \dashrightarrow\sf \: \: Perimeter = AB + BC + AC \\ \\ [/tex]
[tex] \dashrightarrow\sf \: \: 6 + 4 + 2√5 \\ \\ [/tex]
[tex] \dashrightarrow\sf \: \: {\pink{ \underline{ \boxed { \pmb{ \sf{ \: 10 + 2√5 \: \: }}}}}}[/tex]

What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
The points are J(-7, 4), K(-4, 4), L(-2, 3), and M(-8, 3).
We know that distance between two points will be given as
[tex]\rm D= \sqrt{(x_2 - x_1 )^2 + (y_2 - y_1)^2}[/tex]
The distance between JK will be
[tex]JK = \sqrt{(-4+7)^2 + (0)^2 } = 3[/tex]
The distance between KL will be
[tex]KL = \sqrt{(-2+4)^2 + (3-4)^2 } = \sqrt5[/tex]
The distance between LM will be
[tex]LM = \sqrt{(-8+2)^2 + (0)^2 } = 6[/tex]
The distance between JK will be
[tex]MJ = \sqrt{(-7+8)^2 + (4-3)^2 } = \sqrt2[/tex]
Then the perimeter will be
Perimeter = JK + KL + LM + MJ
Perimeter = 3 + √5 + 6 + √2
Perimeter = 9 + √2 + √5

What is 2.1 x 10^4written in standard form is
Answer:
21000
Step-by-step explanation:
You move the decimal point over that many times as the power of 10.
IT is found that [tex]2.1 \times 10^4[/tex] can be written in standard form as 21,000.
Since Scientific notations have some of the profits are Better readability due to compact representation
The value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.
To convert from scientific notation to standard form, we simply move the decimal point to the right by the number of places indicated by the exponent (4 in this case).
Starting with [tex]2.1 \times 10^4[/tex] , we move the decimal point four places to the right to get 21,000.
Hence, [tex]2.1 \times 10^4[/tex] in standard form is 21,000.

Graph the system of linear inequalities on the coordinate plane.
Shade the solution to the system of inequalities.
Pick a point and show your solution is correct.
The graph can be seen at the end, and by looking at it, you can see that a solution can be (10, 0).
How to graph the system of inequalities?
y ≥ (-1/2)*x + 2 + 1/2
y < (1/5)*x + 6
To graph it, first we need to graph the lines:
y = (-1/2)*x + 2 + 1/2
y = (1/5)*x + 6
Once you have this, we analyze each inequality.
y ≥ (-1/2)*x + 2 + 1/2
Because we use the symbol ≥ we need to use a solid line and we need to shade the region above the line.
For y < (1/5)*x + 6 we need to use a dashed line (the symbol < implies that the points on the line are not solutions) and we need to shade the region below the line.
Then the solution of the system is given by the intersection of the shaded region.
For example, a solution can be the point (10, 0), which you can see that belongs to that region.

Step-by-step explanation:
We have to divide
But since it's going too be hard for me to show you the long division, I'm just going to use a multiplication trick!
Let's find what is 20x0.99 first, because I feel like this CAN be the answer.
20x0.99=19.8
So this is not the answer
Now, let's try 22x0.99
22x0.99=21.78
So this is also not the answer.
Now, let's try 21, I think only this one can be the answer.
21x0.99=20.79
So hence, 21 is the right answer. Enzo can buy 21 Kiwis
