A line intersects the points (13,-4) and (1,12). Find the slope and simplify completely.
slope= - ?/?
Answer:
-4/3
Step-by-step explanation:
let (13,-4) be (x1,y1) respectively
(1,12) be (x2,y2) respectively
From,
slope=(y2 -y1)/(x2-x1)
=(12+4) /(1-3)
=16/-12
=-4/3
A system of equation is shown
y=-2x+b
y= 3x+b

b=
Please no link I need help badly!
Answer:
The answer is 6
Step-by-step explanation:
(0,6)
x=0,y=6
Substituting 0 for x and 6 for y
6=2(0) + b
6=b
or
6 = 3(0)+b
6=b
Therefore, b=6

Answer:
equation y = 3x + b.
Step-by-step explanation:
To come up with the equation of a line in slope intercept form, we need the slope and the y-intercept. First, substitute the given slope in for m. We get the equation y = 3x + b.

There are 5 red marbles, 15 blue marbles,
reach in and randomly draw two marbles without replacing the first, what is the
probability that both will be blue?
Answer:
Probability is 0.552, or about 55%
Step-by-step explanation:
first there are 20 marbles in total: odds are 15/20 = 3/4
Then, there are 19 marbles in total : odds are 14/19
So the odds of both of them being blue are: 3/4 * 14/19 = 0.552 (rounded to the thousandths place)

The value of a car is deprecting at the rate of 12% Find the correct value of car when cost of car was rs 350000 last year
Answer:
The cost of the car is $ RS 308,000.
Step-by-step explanation:
Given that the value of a car is deprecting at the rate of 12%, to find the correct value of car when cost of car was $ RS350,000 last year, the following mathematical calculation must be performed:
100 - 12 = 88
88/100 = 0.88
350,000 x 0.88 = X
308,000 = X
Therefore, the cost of the car is $ RS 308,000.

find the percent increase is admission to the amusement park is raised from $70 to $80.
Answer:
14.286% increase
Step-by-step explanation:
Since the admission to the amusement park increased by $10 we need to find what percentage of $70 equals $10.
We can find this percentage by multiplying 10 (the difference in money) by 100 (a hundred percent), and dividing that by 70 (the initial cost)
[tex]10*100/70=14.286[/tex]
Find the equation in terms of x of the line through the points (-4,-6) and (1,9)
Answer:
y = 3x + 6
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - (-6) / 1 - (-4)
15/5
= 3
y = 3x + b
9 = 3(1) + b
9 = 3 + b
6 = b
the sixth graders rasied money to fund a feild trip. the five classes raised $42, $51, $38, $49, and $40. what is the median on the ammount of money raised?
a. $36
b. $42
c. $40
d. $13
Answer:
The median is $42, or B.
Step-by-step explanation:
Our numbers are :
42, 51, 38, 49, and 40.
The first step to finding the median is ordering the numbers from least to greatest.
38, 40, 42, 49, 51.
Now we find the number perfectly in the middle - that's 42, between 49 and 40. The median is $42, or B.

Answer:
∠ DCB = 28°
Step-by-step explanation:

Find the value of x in the isosceles triangle shown below
Answer:
x²+4² =8²
x²+16 =64
x² =64-16.
x² =48
x. =√48
answer is option D
Answer:
D
Step-by-step explanation:
The segment x is a perpendicular bisector and divides the triangle into 2 right triangles.
Using Pythagoras' identity in either of the 2 right triangles, then
x² + 4² = 8²
x² + 16 = 64 ( subtract 16 from both sides )
x² = 48 ( take the square root of both sides )
x = [tex]\sqrt{48}[/tex] → D

an article cost $1424 it may be purchased by depositing $560 and making monthly payment of 48 how many monthly are required to complete payment?
Answer:
18 monthly payments are required to complete payment
Step-by-step explanation:
We start with our $1,424.
Then subtract $560 from the original number above.
Leaving us with $864.
We then divide the $864 by $48 and we end up with 18.
So our answer is 18 monthly payments are required to complete payment.

Step-by-step explanation:
a) Given,
Total marks in English = 90
Marks scored by James = 60
Therefore,
Percentage of marks scored
[tex] = \frac{60}{90} \times 100[/tex]
= 66.67% (approx. )
Then,
Total marks in Science = 150
Marks scored by James = 78
Therefore,
Percentage of marks scored
[tex] = \frac{78}{150} \times 100[/tex]
= 52%
At last,
Total marks in Maths = 120
Marks scored by James = 75
Therefore,
Percentage of marks scored
[tex] = \frac{75}{120} \times 100[/tex]
= 62.50%
b) In English test James scored highest percentage.

Answer:
w = 16, x = 11, y = 6, z = 7.5
Step-by-step explanation:
The scale factor is the ratio of corresponding sides, image to original.
scale factor = [tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex]
Then by proportion
[tex]\frac{12}{w}[/tex] = [tex]\frac{3}{4}[/tex] ( cross- multiply )
3w = 48 ( divide both sides by 3 )
w = 16
----------------
[tex]\frac{x}{12}[/tex] = [tex]\frac{3}{4}[/tex]
4x = 36
x = 9
-------------------
[tex]\frac{4.5}{y}[/tex] = [tex]\frac{3}{4}[/tex]
3y = 18
y = 6
----------------------------
[tex]\frac{z}{10}[/tex] = [tex]\frac{3}{4}[/tex]
4z = 30
z = 7.5

Container B now contains 4 times as much liquid as A.
Find the volume of liquid left in container A at the end.
A
A
B.
B
Volume left in container A=
20
ml
Answer:
volume left in A is 80ml
Step-by-step explanation:
let original volume in both be x ml
after pouring from A to B
vol in A = x - 120
vol in B = x + 120
now it is given that
vol in B = 4 times vol in A
implies
[tex]x + 120 = 4 \times (x - 120) \\ x + 120 = 4x - 480 \\ 3x = 600 \\ x = 200[/tex]
hence original volume in A is 200ml. after pouring in B it is 200-120 = 80 ml
