Answer:
(2x-5)(3x-2)
Step-by-step explanation:
1)When factoring quadratic equations in for ax²+bx+c you need to separate the b term in a way that the two addends you separate it by should equal a•c. Just do trial and error. In this case you should get -4 and -15. Your separated equation should be:
6x²-4x-15x+10
2)now factor out a common factor from the first two terms and one from the last two terms you should have:
2x(3x-2)-5(3x-2)
3)finally rewrite this equation into two separate factors and you have your answer.
Compare interior intersections and
exterior intersections. How are they the
same? How are they different?
Answer:
Interior intersections are those intersecitons inside the main figure. For example, the intersection between two chords of a circle, that represents an interior intersection.
Exterior interseciton are those intersections which happens outside the figure, for example, the intersection of two tangent lines of a circle.
Basically, they are similiar, because both type of intersections are formed by the encounter between two lines or segments.
However, they are different, because each type is formed at different parts of the figure, one inside and one outside.

Write an expression for the volume of a rectangular prism with length 7.5 ft, width w ft, and height 4.2 ft. Enter the smaller number first. sad :'(
Answer:
volume = 31.5w
Step-by-step explanation:
A rectangular prism is a 3 dimensional figure that have 6 faces that are rectangular in shape. To ascertain the volume of a rectangular prism you need to know the length, width and height. The formula for the volume of a rectangular prism is represented below .
volume of a rectangular prism = LHW
where
L= length
H = height
W = width
volume = LHW
L = 7.5 ft
W = w ft
H = 4.2 ft
The expression for the volume of a rectangular prism with the following value above can be represented below.
volume = 4.2 × 7.5 × w
volume = 31.5w

Team Sports Sport Number of Players Baseball 9 Basketball 5 Football 11 Hockey 6 Lacrosse 10 Polo 4 Rugby 15 Soccer 11 Enter the ratio of lacrosse players to baseball players in the form a b and then as a decimal showing up to four decimal places. Tell whether the decimal is a terminating or a repeating decimal.
Answer:
Ratio of Lacrosse players to Baseball players is 10:9 or 10/9
Step-by-step explanation:
A ratio can be seen as a relationship between two values which is based on quantitative measures.
To do this simply we divide the values of the quantities that we want to determine the ratio of which on is to the other.
It can be seen as Value of quantity A / Value of quantity B
In this case, quantity A is the Lacrosse players, and it has a value of 10
quantity B represents the Baseball players with a value of 9.
Hence the ratio is [tex]\frac{10}{9} = 1.1111[/tex]
It can also be written as 10: 9
The decimal is a repeating decimal because the numbers after the decimal points take up a pattern that repeats themselves up to infinity.
A taxi company charges a fixed hire fee (which is a whole number of dollars) plus a rate for each
kilometer (which is a multiple of 10¢ and more than the set national minimum rate of $1.75),
rounded up to the nearest kilometer.
Maira’s last journey cost $37.90, but she does not know how far it was, or what the fixed hire fee
is. She wants to know how far the journey was.
She has a previous bill from the same taxi company, for a different journey, for $21.80.
How far was her last journey?
Answer:
362 kilometre
Step-by-step explanation:
Let a be the total cost of a journey
let b represent the total distance of a journey
$1.75 is a fixed charge of a journey
the additional charge is $0.10 for b distance ,hence total of additional charge is $.10 multiplied by b i.e 0.1 b
a=1.75+0.1b
a =37.90
37.90=1.75+0.1b
0.1b=37.90-1.75
0.1 b=36.15
b=36.15 /0.10
b=361.5
b=362 kilometre
For the journey that cost 21.80
21.80=1.75+0.1 b
0.1 b=21.80-1.75
0.1 b=20.05
b=20.05 /0.1
b=200.5
b =201 kilometre
Use the quadratic function to predict f(x) if x equals 2.
f(x) = -3x^2 + 180x - 285
Answer:
When x = 2, f(x) = 63.
Step-by-step explanation:
In order to find the value of f(x), you have to substitute x = 2 into the function :
[tex]f(x) = - 3 {x}^{2} + 180x - 285[/tex]
[tex]f(2) = - 3{(2)}^{2} + 180(2) - 285[/tex]
[tex]f(2) = - 12 + 360 - 285[/tex]
[tex]f(2) = 63[/tex]

Jack and his cousin Emma are picking apples in their grandparents' orchard. Jack has filled 11 baskets with apples and is filling them at a rate of 5 baskets per hour. Emma has 8 full baskets and will continue picking at 6 baskets per hour. Once the cousins get to the point where they have filled the same number of baskets, they will carry them to the barn and then eat lunch. How long will that take? How much fruit will they have picked by then?
Answer:
3 hours
26 baskets each giving a total of 52 baskets
Step-by-step explanation:
Jack has already filled 11 baskets with apples and is filling them at a rate of 5 baskets per hour. This means that in x hours he would have filled an additional 5x basket to the initial 11 baskets. Therefore the number of baskets that Jack would have filled in x hours can be given by:
11 + 5x
Emma has already filled 8 baskets with apples and is filling them at a rate of 6 baskets per hour. This means that in x hours he would have filled an additional 6x basket to the initial 11 baskets. Therefore the total number of baskets that Emma would have filled in x hours can be given by:
8 + 6x.
The time it would take Emma and Jack to have completed the same number of baskets can be gotten by using this equation and solving for x:
11 + 5x = 8 + 6x
11 - 8 = 6x - 5x
x = 3 hours.
It would take them 3 hours to fill the same number of baskets.
The number of fruits Jack would have picked in 3 hours = 11 + 5(3) = 26 baskets.
The number of fruits Emma would have picked in 3 hours = 8 + 6(3) = 26 baskets.
Both Emma and Jack would have picked 26 baskets each, giving a total of 52 baskets

Nick is solving the equation 3x^2=20-7x with the quadratic formula
which values could He use for a, b and c
Answer:
C. a = 3
b = 7
c = -20
Step-by-step explanation:
x = -b+/- (sq) b^2 - 4ac.
Well the way to plug the numbers in is by using this equation: Ax^2 + Bx + C = 0
S if you use your equation : 3x^2 = 20 - 7x
First you have to move everything to one side.
So it'll look like this:
3x^2 = 20 - 7x
-20 -20
3x^2 - 20 = -7x
+7x +7x
3x^2 - 20 + 7x = 0
don't forget that... Ax^2 +Bx+ C= 0
3 = A
7 = B
-20 = C
Complete equation of the line through (1,4) and (2,2)
Answer:
y = -2x + 6
Step-by-step explanation:
y=mx + c
m is the gradient and c is the y intercept
m = (y 2 - y 1) / (x 2 - x 1) = (2-4) / ( 2-1) = -2
y= -2x + c
To find c, just sub one of the coordinates into the eqn:
By using the coordinates (1,4)
4 = -2(1) + c
c = 6
Therefore, the equation is y = -2x + 6
The population of the united states is 280 million. If 2 out of 3 americans know who the vice president is, how many americans know who the vice presdient is?
Answer:
186,666,667 Americans know who the vice president is
Step-by-step explanation:
In this question, we are tasked with calculating the number of USA citizens that know who the vice president is.
Now, in this question, we are made to know that the total population is set at 280 million with 2 out of three knowing who the vice president is.
What this means is that a fraction of the population at 2/3 knows who the vice president is
This fraction is equal to; 2/3 * 280,000,000 = 186,666,666.66666666
This is approximately equal to 186,666,667 people
Answer:
About 186.7 million people know who is the president of the United States.
Step-by-step explanation:
The number of US people who know who the vice president is (Mike Pence in 2020):
[tex]x = \frac{2}{3}\cdot (280\times 10^{6}\,people)[/tex]
[tex]x = 186.667\times 10^{6}\,people[/tex]
About 186.7 million people know who is the president of the United States.

PLEASE HELP!!!!! Consider the functions f(x)=x−7 and g(x)=4x3.
What is f(x)+g(x)?
Answer:
The answer is 13x-7
Step-by-step explanation:
f(x) is x-7, and g(x) is 4x3. 4x3 can also mean 12x , because 4x3 is 4*x*3. So, f(x) can be replaced with x-7, and g(x) can be replaced by 12x. (x-7)+(12x) is 13x-7.
