Method elimination would be good for this system
2x - y = 7 ........ (1)
x + y = 5 ......... (2)
(1) + (2)
3x = 12 ⇒ x = 4
4 + y = 5 ⇒ y = 1
(4, 1)
Y= 0.75
4.25 +0.75 = 5
4.25 - 0.75 = 3.5

One of the slowest fish is the blenny
fish. The function y = 0.5x describes
how many miles y the fish swims in
x hours. Graph the function. Use the
graph to estimate the number of miles
the fish swims in 3.5 hours.
.
Answers
Answer:
It swims 1.75 miles in 3.5 hours. X stands for hours so x=3.5. Y stands for miles so y=1.75.
Step-by-step explanation:
your equation is y=0.5x
we know x=3.5
so y= 0.5(3.5)
solve and you get y= 1.75
so in (x,y) intercept format (3.5,1.75) and you can make a graph and label your x intercepts hours and your y intercepts miles traveled.
The number of miles the fish swims in 3.5 hours is 1.75 miles.
The equation of a straight line is:
y = mx + b;
y, x are variables, m is the slope of the line and b is the y intercept.
Given the function: y = 0.5x;
where y represent the miles the fish swims in x hours.
The graph of the function is plotted using geogebra online graphing tool.
From the graph, the number of miles the fish swims in 3.5 hours is 1.75 miles.

Answers
Step-by-step explanation:
Mean is the ratio of the sum of the sample data to the total sample size.
1) Given the set of data 2.4, 1.6, 3.2, 0.3, 1.5, if each piece of data is increases by 10, the new data's will be;
(10+2.4), (10+1.6), (10+3.2), (10+0.3), (10+1.5)
sum of the new data's = 59
Sample size = 5
Mean = 59/5
Mean = 11.8
Hence if the price of data is increases by 10, its new mean will be 11.8
2) If each new piece of data is doubles, the new set of data will be;
2(2.4), 2(1.6), 2(3.2), 2(0.3), 2(1.5)
= 4.8, 3.2, 6.4, 0.6, 3.0
Sum of new data = 4.8+3.2+6.4+0.6+3.0
Sum of new data = 18
sample size = 5
Mean = 18/5
Mean = 3.6
Hence the new mean if the data were doubles is 3.6

She visited Creepy Cavern at (-2, 5), Bernie's Barn at (-3, 2), Sweet Symphonies at (-3, -1), Rock and Roll Hall at (-2, -4), Whimsical Wonders at (3, -4), Mystery Mansion at (3, 2), and Star Gazing Point at (5, 5). Which of these pairs of places are more than 6 units from one another?
Answers
Answer:
We need to find the distance between the pairs of points to know which is greater than 6units. To do that we make use of this formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Where [tex](x_1 , y_1)[/tex] and [tex](x_2 , y_2)[/tex] are two points on the line.
Let us denote Creepy Carven with CC, Bernie Barn as BB, Sweet Symphonies as SS, Rock and Roll Hall as RR, Whimsical Wonders as WW, Mysterial Mansion as MM and Star Grazing point as SG.
The distance between CC (-2, 5) and BB(-3, 2) using that formula will be:
[tex]d = \sqrt{(-3 + 2 )^2 + (2 - 5)^2}[/tex]
Which is [tex]d = \sqrt{(-1 )^2 + (-3)^2}[/tex]
That gives
[tex]d = \sqrt{10} < 6[/tex]
If we do this for BB to SS we have our value greater than 6, SS to RR our value greater than 6, RR to WW greater than 6, WW to MM is equal to 6 and MM to SG is less than 6.
From here we conclude that the pairs of places greater than 6 is:
BB to SS
SS to RR
RR to WW
WW to MM
Answer:
First, plot each of the points and label them.
Determine the distance between the pairs of places listed in each answer choice.
Since Whimsical Wonders and Rock and Roll Hall lie on the same horizontal line, the distance between the two points is the absolute value of the difference of the x-coordinates.
Using this same process, the distance between Bernie's Barn and Mystery Mansion is 6 units, and the distance between Creepy Cavern and Star Gazing Point is 7 units.
Since the Mystery Mansion and Whimsical Wonders lie on the same vertical line, the distance between the two points is the absolute value of the difference of the y-coordinates.
Using this same process, the distance between Rock and Roll Hall and Creepy Cavern is 9 units, and the distance between Sweet Symphonies and Bernie's Barn is 3 units.
Therefore, the pairs of places that are more than 6 units from one another are Creepy Cavern and Star Gazing Point and Rock and Roll Hall and Creepy Cavern.

Answers
Answer:
The length of segment JK is 5[tex]\sqrt{5}[/tex] ⇒ C
Step-by-step explanation:
The formula of the distance between the two points (x1, y1) and (x2, y2) is
d = [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}[/tex]
Let us use the formula above to solve the question
∵ Jk is a line segment
∵ J = (4, 8) and K = (-1, -2)
∴ x1 = 4 and y1 = 8
∴ x2 = -1 and y2 = -2
→ Substitute them in the formula above
∵ JK = [tex]\sqrt{(-1-4)^{2}+(-2-8)^{2}}[/tex]
∴ JK = [tex]\sqrt{(-5)^{2}+(-10)^{2}}[/tex]
∴ Jk = [tex]\sqrt{25+100}[/tex]
∴ Jk = [tex]\sqrt{125}[/tex]
→ Simplify the root
∵ 125 = 5 × 5 × 5
∴ [tex]\sqrt{125}[/tex] = 5[tex]\sqrt{5}[/tex]
∴ JK = 5[tex]\sqrt{5}[/tex]
∴ The length of segment JK is 5[tex]\sqrt{5}[/tex]
