Drew is buying a $325,000 house. He will put a 4.5% down payment and finance the
rest of the price with a mortgage loan. What is the mortgage loan amount? Round your
answer to the nearest thousand
$310,000
$300.000
0 $311.000
$275,000
Answer:
$311,000
Step-by-step explanation:
Original cost of house = $325,000
Mark down percent = 4.5%
Markdown price = 4.5% * 325000
Markdown price = 0.045*325000
Markdown price = $14,625
Mortgage loan amount now = $325,000 - $14,625
Mortgage loan amount now = $310,375
Mortgage loan amount now tom the nearest thousand is $311,000

Functions A,B and C are linear functions. Some values of function A are shown in the table. Function B has y-intercept of (3,0) and a x-intercept of (5,0). Function C is defined by the equation y=3x+1.
HERES THE TABLE
X. 3,5,6
Y. 3,7,9.
Create equations for each of the 3 functions given above?
Order the linear functions based on rate of change from least to greatest?
Answer:
In order of increasing slope:
B: y = 0
A: y = 2x-3
C: y = 3x+1
Step-by-step explanation:
(3,3), (5,7), and (6,9) are points on line A.
Use the coordinates of two of the points to find the slope of A.
Δy =7-9 = -2
Δx =5-6 = -1
Slope = Δy/Δx = 2
Equation for line of slope 2 that passes through (3,3):
y-3 = 2(x-3)
y = 2x-3
(3,0) and (5,0) are points on line B. They are horizontally aligned, so the equation for line B is y=0. Slope = 0.
You were given the equation for C: y = 3x+1. Slope = 3
In order of increasing slope:
B: y = 0
A: y = 2x-3
C: y = 3x+1

about 7.8 units
Answer:
a) d = 8.5 units
The distance of a line segment with end points
d = 8.5 units
Step-by-step explanation:
Step(i):-
Given points are G(4,9) and H( 7,1)
By using distance formula
G H = [tex]\sqrt{x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]
Step(ii):-
[tex]d = \sqrt{7-4 )^{2} +(1-9 )^{2} }[/tex]
d = [tex]\sqrt{3)^{2} +(-8 )^{2} } = \sqrt{9+64} = \sqrt{73}[/tex]
d = 8.5 units

Answer:
x = 30°DB = 26AD = BC = AB = DC = 7Step-by-step explanation:
Diagonals of a square are congruent and perpendicular and bisect each otherQ4m∠AEB = 3x
m∠AEB = 90°
3x = 90° ⇒ x = 30°Q5AE = 3x - 2
EC = 2x + 3
AE = EC3x - 2 = 2x + 33x - 2x = 3 + 2x = 5DB = EC = 2(AE) = 2(3*5 - 2) = 2(13) = 26
Q6AD and BC are the sides, which are equal
2x - 1 = 5x - 135x - 2x = 13 - 13x = 12x = 4AD = BC = AB = DC = 2*4 - 1 = 7

Step-by-step explanation:
Jack and Jill each go out shopping.
Jack spends 1/3 of his money.
Jill spends 40% of her money.
Frank says Jack spent more because 1 /3 is greater than 40%.
Alice says you cannot tell who spent more.
Who do you agree with, Frank or Alice? Explain why.
I agree with Alice because you do not know how much money Jill and Jack had before they went shopping. If they had the same amount of money Jill would have spent more because 40 percent is greater than 1/3.

A clothing store is having a sale. A shirt normally sells for $30. The store is
offering a 15% discount. What is the discounted price?
A. $4.50
B. $25.50
C. $26.50
D. $24.50
Answer:
B. $25.50
Step-by-step explanation:
This is a bit of a trick question.
To find how much money is taken off the price, you would do 15% (0.15) • 30 and you get $4.50. This is the discount that is taken off of the price, not the discounted price. To find the new discounted price, subtract the $4.50 from $30.00.
$30.00 - $4.50 = $25.50

A squar has an area of 64cm2 find the perimeter of the square
Answer: 32 cm
Step-by-step explanation:
Answer:
All of the sides of the square are 8 cm. So the prementer would be 32 cms
Step-by-step explanation:
To find the sides of the square, you got to think what x what = 64. This shows you that 8 x 8 is 64. and since it is a square, all of the sides are the same. So 8+8+8+8 = 32 or you can do 8 x 4 = 32

Find the equation of the line that goes through the points (12, 11) and (7,1)
Answer:
8,4
Step-by-step explanation:
Step 1: Find the slope of the line.
Step 2: Use the slope to find the y-intercept.
Step 3: Use steps 1 and 2 to write the answer.
I will explain these steps by looking a several examples. Please understand that there are often several
different ways to complete each math problem, but I have found through the years that students are most
successful when the do problems the same way each and every time they attempt the problem. If you
know a different way to find the answer that is great, but I am going to show how to do the problem one
way and use the same technique everytime I see this problem.
Example 1: Find the equation of the line passing through the points (–1, –2) and (2, 7).
Step 1: Find the slope of the line.
To find the slope of the line passing through these two points we need to use the slope
formula:
( )
( )
So the slope of the slope of the line passing through these two points is 3.
Step 2: Use the slope to find the y-intercept.
Now that we know the slope of the line is 3 we can plug the slope into the equation and
we get:
y = 3x + b
Next choose one of the two point to plug in for the values of x and y. It does not matter
which one of the two points you choose because you should get the same answer in either
case. I generally just choose the first point listed so I don’t have to worry about which
one I should choose.
(–1, –2) → –2 = 3(–1) + b Multiply to simplify the problem.
–2 = –3 + b Solve for b and you will have the y-intercept.
b = 1

A watermelon weighs 6.45 kilograms. How many grams does the watermelon weigh?
Answer:
A watermelon weighs about 3 (grams /(kilograms) 3.
Step-by-step explanation:
Answer:
6,450 g
Step-by-step explanation:
Since there are 1000 grams in 1 kilogram, you multiply 6.45 kg x 1000 g.
6.45 x 1000 g equals 6,450 grams. Move the decimal 3 times to the right because there are 3 zeroes in 1000.
You always move your decimal to the right when multiplying decimals.

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]\bigtriangleup = b^{2} - 4ac[/tex]
In this question:

[tex]x_1 = 1 - 3i, x_2 = 1 + 3i[/tex]

[tex](x - (1 - 3i))(x - (1 + 3i)) = x^2 - x(1 + 3i) - x(1 - 3i) + (1 - 3i)(1 + 3i) = x^2 - x -3ix - x + 3ix + 1^2 - (3i^2) = x^2 - 2x + 1 - 9i^2 = x^2 - 2x + 1 - 9(-1) = x^2 - 2x + 10[/tex]

Roberta bought 9/10 pound of raisins. She put 2/5 pound in bags for her lunch. How many 2/5 pound bags can Roberta fill? Does she have any left over?
Answer:
2 pound bags and have a remeinder of 1/10
Step-by-step explanation:
Answer:
She can fill 2 bags for her lunch and will have 1/10 pound left.
Step-by-step explanation:
It is easier if there is a common denominator, so I made the 2/5 into 4/10, so it is the same as 9/10 pound she bought.
4/10 is one bag, and if you double that, it is 8/10 pounds used. This is two bags of raisins for her lunch.
9/10 - 8/10 leaves 1/10 pound remaining, and not in a bag.

Function c is defined by the equation c(n)=50+4n. It gives the monthly cost, in dollars, of visiting a gym as a function of the number of visits, n. What is the inverse function.
Answer:
(x - 50 / 4) = y
Step-by-step explanation:
On photo
To find the inverse function, you will have to write n in terms of c (which means number of visits as function of monthly cost).
The inverse function would be:
[tex]n = \dfrac{c-50}{4}[/tex]
Given that:c(n) = 50 + 4nc is monthly cost in dollars, of visiting a gym.n is the number of visits.To find:Inverse function of given function.
What is inverse function and when is it possible to find such function?The inverse function of f is a function of f which can remove the effect of f on its input.
Inverse is only possible if the function f is bijective (one to one correspondence, which means one input to one output uniquely and one output is connected to only one input by mapping f)
Since the given function is a linear function and not a vertical line, thus, one input n uniquely maps to one output cost and one cost uniquely is obtained by one and only one value of n.
Finding the inverse function of c(n) = 50 + 4n:[tex]cost = 50 + 4n\\ 4n = cost - 50\\\\ n = \dfrac{\text{c - 50}}{4} \text{\: (assuming cost to be denoted by c)}[/tex]
Thus, we have the inverse function of given function as:
[tex]n = \dfrac{c-50}{4}[/tex]
