Step-by-step explanation:
look at the 5 on the x axis and see where the y crosses it
y+4x=2 in slope intercept form
Answer: y=-4x+2
Step-by-step explanation: You have to get Y by itself so you subtract 4x from the right and you get -4x+2 with Y by itself
A triangle has side lengths of 12 inches 14 inches, and 18 inches. What best represents the perimeter of the triangle in centimeters? (1 inch ~ 2.54 centimeters)
Answer:
111.76 cm
Step-by-step explanation:
The formula for the perimeter of a triangle is given as:
Side A + Side B + Side C
Since our final answer is going to be in centimeters we have to convert the sides from inches to centimeters
Hence:
1 inch ~ 2.54 centimeters
For 12 inches
1 inch = 2.54 cm
12 inches = x
Cross Multiply
x = 12× 2.54 cm
x = 30.48 cm
For 14 inches
1 inch = 2.54 cm
14 inches = x
Cross Multiply
x = 14× 2.54 cm
x = 35.56 cm
For 18 inches
1 inch = 2.54 cm
18 inches = x
Cross Multiply
x = 18× 2.54 cm
x = 45.72 cm
Hence, the perimeter of the triangle
= 30.48 cm + 35.56 cm + 45.72 cm
= 111.76 cm
m+2=7/n make n the subject
Answer:
[tex]n = \frac{7}{m + 2} [/tex]
Step-by-step explanation:
[tex]m + 2 = \frac{7}{n} [/tex]
To make n as the subject , we need to isolate it.
■ Lets multiply n on both the sides in order to shift n to the L.H.S.
[tex] = > n(m + 2) = \frac{7}{n} \times n[/tex]
[tex] = > n(m + 2) = 7[/tex]
■ Lets now divide (m + 2) on both the sides in order to isolate n in L.H.S
[tex] = > \frac{n(m + 2)}{( m+ 2)} = \frac{7}{(m + 2)} [/tex]
[tex] = > n = \frac{7}{m + 2} [/tex]

A 5k marathon is equivalent to how many miles.? (Conversion factor: 1 mile = 1.6 km)
Answer:
3.10686
Step-by-step explanation:
Divide the kilometer by 1.609
9514 1404 393
Answer:
3 1/8 miles
Step-by-step explanation:
Using your conversion factor ...
(5 km) × (1 mi)/(1.6 km) = (5/1.6) mi = 25/8 mi = 3 1/8 mi
A 5k race is about 3 1/8 miles.

What is the x-coordinate of the image when M(4, -1) is reflected in y = 3.
Answer:
4
Step-by-step explanation:
y=3 is a horizontal line, so it will not affect the x coordinate.
The x-coordinate of the image when M(4,-1) is reflected in y = 3 is : 4
What is reflection?Reflection is the mirror image of a shape.
It is the process of flipping a shape around a certain axis to look like the original shape.
Analysis:
Since the reflection is at y = 3 which is along the x-axis, only the y coordinate changes. The x coordinate remains the same. So, the x- coordinate is still 4.
In conclusion, the x-coordinate is 4.

Q3.
Oscar is organising a show.
Visitors to the show choose their seats at random.
There are 350 seats available.
These seats are numbered from 1 to 350
Oscar places a prize under each of the seats numbered 17 to 25
(a) What is the probability that the first visitor chooses a seat with a prize?
The probability that the first visitor chooses a seat with a prize is 0.0229.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, Oscar is organizing a show.
If there is a prize under (25 - 17) + 1 = 9 seats as both 17 and 25 are included and there is a total of 350 chairs,
The probability that the first visitor chooses a seat with a prize is (8/350).
= 4/175.
= 0.0229

1)TX=XV=√39
2)WX=XU=5
In the given rhombus TUVW
TW=8(Given)
WX=5(Given)
What is a rhombus?A rhombus is a quadrilateral whose four sides all have the same length.
As we know that diagonals of the rhombus intersect at a right angle
So, by Pythagoras' theorem
[tex]TW^2 = TX^2 + WX^2\\8^2=TX^2 + 5^2\\TX = \sqrt{39}[/tex]
We know that the diagonals of a rhombus bisect each other
So XV =√39
Similarly, XU=WX =5.
Therefore, in the given rhombus TUVW
1)TX=XV=√39
2)WX=XU=5

B7 formula: =AVERAGE(B3:B6)
B8 formula: =B1*B2*B7
Step-by-step explanation:
There are two parts to finding the answer to the questions posed. (1) You need to understand what you are being asked to calculate. (2) You need to know how to write that calculation as a spreadsheet formula.
It is beyond the scope of this answer to give a tutorial in spreadsheets. Many web sites, videos, books, and other help sources are available to teach you how to open and use a spreadsheet. Presumably, you've been given an introduction in your class.

a) The problem statement tells you that cell B7 contains the average of the values in cells B3 to B6.
The AVERAGE function will compute the average of a range of cells. It can be used in cell B7 to compute the average of the values in cells B3 to B6. The formula would generally be written ...

b) Problem 10 doesn't tell you explicitly what the pension formula is. We have to assume that it is similar to the formulas described in problems 8 and 9. That is, it is the product of a percentage, years worked, and the average of some number of salaries. In problem 10, the average is of 4 salaries.
The value in B8 will be the product of the pension credit percentage per year worked, the number of years worked, and the average of the last 4 years' salaries. Those values are in cells B1, B2, and B7, so the formula is written ...
