Which equation has a slope of -3/4 and goes through the point (-3,4)?​

Answers

Answer:

Step-by-step explanation:

First write a point-slope equation y−y1=m(x−x1) , where (x1,y1) is the given point, (4,2) , and m is the slope, −3 . For graphing, you can convert to the slope-intercept form, y=mx+b , by solving for y , where m is the slope and b is the y-intercept.

Of the 1450 books in the library, there are 6 times as many books in the fiction section as are in the nonfiction section. Also, there are 400 more books in the reference section than are in the nonfiction section. How many books are in each section?
Fiction: Nonfiction: Reference:

Answers

Number of books in non fiction section  = 200

Number of books in fiction section  = 800

Number of books in reference section  = 850

Step-by-step explanation:

Total number of books in the library = 1850

Let us assume, number of books in non fiction section = m

Number of books in fiction section= 4 x Number of books in non  fiction

= 4  x  (m)

So, the number of books in reference section = 650 + m

Now, Total Number of books =  Number of { Fiction + Non- Fiction + Reference} Books

or,  1850 =  m + (4 m)  + 650 + m

or, 6 m + 650 = 1850

⇒ 6 m = 1850 - 650 = 1200

or, m = 1200 / 6 = 200  

⇒ m = 200

Hence, the number of books in non fiction section  = 200

Number of books in fiction section  =  4 m = 4 x 200 = 800

Number of books in reference section = 650 + m  = 200 + 650 = 850

8. Identify the mapping diagram that represents the relation and determine whether the relation is
a function.
(-5,-4), (-1,5) (-5,3),(7,8)

Answers

Answer:

Well, you didn't give a picture of the available mapping diagrams, so I can't tell you that.  However, I CAN tell you that the relation is not a function.

Step-by-step explanation:

A function occurs when each input only has one output.  For example if the input is 5, it can only give 1 y-value out.  It cannot give 2,3,4...etc values.  This relation is not a function because -5 maps to both -4 and 3.  That's one input to two outputs, which breaks the rules of a function.

Which should be the first step in solving the equation 1.2 w minus 3.8 = 12.4? Add 3.8 to both sides of the equation. Subtract 1.2 from both sides of the equation. Multiply both sides of the equation by 1.2. Divide both sides of the equation by 3.8.

Answers

Answer:

Add 3.8 to both sides of the equation.

Step-by-step explanation:

12w−3.8=12.4

Add 3.8 to both sides.

12w=12.4+3.8

Add 12.4 and 3.8 to get 16.2.

12w=16.2

Divide both sides by 12.

w= 12/16.2

​Expand  12/16.2 by multiplying both numerator and the denominator by 10.

w= 162/120

​Reduce the fraction  162/120 to lowest terms by extracting and canceling out 6.

w= 27/20 also equal to 1.35

You operate a local mortgage & loan business with two other partners. Your role is to adjust
the prime interest rate for variable & fixed mortgages for your customers, as well as deal
with the length of a mortgage.
1. A client comes in looking to apply for a mortgage, but does not have any prior knowledge.
Answer the following questions to help them decide which type of mortgage to get.
(a) At most banking institutions, there are two types of mortgages available: fixed
mortgages and variable mortgages. Describe the difference between the two main
types of mortgages. Give one positive and one negative aspect of each type of
mortgage
(b) Banks will often advertise interest rates using the terminology prime plus/minus
percent. For example, if prime is 1.5%, then 2.5% might be advertised as prime plus
1%. Express 1.45% and 4.35% using the terminology of prime plus/minus percent
using Canada's current prime interest rate.
2. How many years will it take for your client to pay off a mortgage of $250,000 if he makes
month-end payments of $1,500? Assume a fixed interest rate of prime minus 0.5% over
the term of the whole mortgage. You may answer either by hand, or using the calculators
TVM buttons. If you use the calculator, ensure you write down all of your inputs for
full marks. No time diagram is necessary.
3. Your client borrows $250,000 and agrees to pay $1,500 at the end of every month for
a 5-year term. At the end of years, there is $200,000 remaining on the mortgage.
Use the calculator's TVM buttons to determine the fixed interest rate on this mortgage
(you will be unable to do this any other way). Write down all of your inputs, paying
careful attention to negative signs, for full marks. Express your final answer using prime
plus/minus terminology. No time diagram is necessary

Ruby drank 4/5 liter of water Monday before jogging.She drank 2/3 liter of water after her jog.How much water did Ruby drink altogether?

Answers

Answer:

22/15, or  Liters of Water

Step-by-step explanation:

First find a Common Denominator, which in this case would be 15. But, you have to make the numerators numbers that can be with the new common denominator, so multiply 2*5, and that's 10, and 4*3, which is 12. Since the problem is  asking you to find out how much water she drank in total, you can just add the numbers up since the denominators the same. So with the new numbers 10/15, add that with 12/15, and you get 22/15. At this point you can either keep it as 22/15, or you can make it into a mixed number of 1 7/15 as your final answer.

Step-by-step explanation:

We can write two expressions for the area of the figure by treating the figure as one whole rectangle, and also as two different rectangles in one.

The two expressions are as follows:

Expression of Area as one whole rectangle:

Area of a rectangle = length × width

Length = (n + 10) ft

Width = 20 ft

Area = (n + 10)× 20 = 20(n + 10)

Area of rectangle as two rectangles in one piece:

Area of the larger rectangle = length × width = n × 20 = 20n

Area of the smaller rectangle = length × width = 20 × 10 = 200

Total area = 20n + 200

2. The bottom of a ladder must be placed 10 feet from a wall and reach a height of 16 feet. How long is the ladder?

I need help pls

Answers

Answer:

Step-by-step explanation:

Remark

Question One

It's equilateral. All three sides are equal. The base is 34 as well. So two right angles can be formed on the base by dropping the altitude from the top vertex.

Givens

altitude = h

a = 34/2 = 17

hypotenuse = 34

Formula

a^2 + h^2 = c^2

Solution

17^2 + h^2 = 34^2

289 + h^2 = 1156

h^2 +289 =1156

h^2 = 1156 - 289

h^2 = 867

sqrt(h^2) = sqrt(867)

h = 29.444

==============

Question Two

Givens

b = 10 feet

c = ?

height = h = 16

Formula

c^2 = b^2 + h^2

Solution

c^2 = 10^2 + 16^2

c^2 = 100 + 256

c^2 = 356

sqrt(c^2) = sqrt(356)

c = 18.87

m * n is the common denominator. Multiply the two fractions by mn
