Factor 2/3x+4 2/3 linear equation hint 2/3 is gcf please help!!!!!
Answer:
To factor the expression 2/3x + 4, we first need to find the greatest common factor (GCF) of the coefficients of the terms in the expression. In this case, the GCF is 2/3, so we can write the expression as (2/3)(x + 12/2). This is the factored form of the expression, and it can be simplified to (1/3)(2x + 6).
Step-by-step explanation:
a train leaved the station at 5=0 traveling at a constasnt speed the train travels 360 kilometer in 3 hours Write a function that relates the distance traveled d to the time t
The function is determined using speed and is found to be d = 120t.
What is speed?Speed is generally the change in distance per unit time. (rate of change of distance)
What is the formula of speed?To calculate speed, we will use speed = distance/time.
speed = 360/3
= 120km/hr
Since, the train is moving with a constant speed the ratio of distance and time will be equal to 120 throughout the journey.
120 = d/t
Hence, d = 120t.

How many different flag can be made from 10 colors of cloth if each flag is consist of 3 diffferent stripes?
Answer: 1000 different flags
Step-by-step explanation:
So for the flag there are 10 color options and you need to have 3 different stripes. Where you are able to use a color more than once.
For the first stripe there are 10 options so it can be any of the 10 choices.
For the second option you are able to use any of the 10 colors again so it can be any of the 10 colors.
For the last option for stripe 3 you can pick from ay of the 10 colors so there are 10 color options is could be.
Now that you know the how many choices of color there can be for each stripe you multiple the color choice for each stripe by each other to get the number of combinations for different flags.
colors for stripe 1x colors for stripe 2x colors for stripe 3= # of different flags
10x10x10=1000
so there can be 1000 different 3 stripe flags that can be made with 10 colors

Find the area between the curves y=x^2 and y=-3*x
the area between the curves y=[tex]x^{2}[/tex] and y=-3x is 9/2 sq units
What is the area of the curve?By performing a definite integral between the two point, one may determine the area under a curve between two points. Integrate y = f(x) between the limits of a and b to determine the area under the curve y = f(x) between x = a & x = b. With the specified restrictions, integration may be used to compute this area.
The area between the curves y=[tex]x^{2}[/tex] and y=-3x
y=[tex]x^{2}[/tex] and y=-3x
firstly calculated the point of intersection. y = y
[tex]x^{2}[/tex] = -3x
[tex]x^{2}[/tex] + 3x = 0
x( x+ 3) = 0
x = 0 , x = -3
point of intersection is 0 , -3
Area = [tex]\int\limits _ {} \, x^{2} + 3xdx[/tex] from -3 to 0
Area = [ [tex]x^{3}/3 + 3x^{2} /2[/tex] ] from -3 to 0

The length of the longer leg of a right triangle is 6inches more than twice the length of the shorter leg. The length of the hypotenuse is 9inches more than twice the length of the shorter leg. Find the side lengths of the triangle.
The length of shorter leg is 15 inches, length of longer leg is 36 inches and the length of hypotenuse is 39 inches.
What is right triangle?
A right triangle, also known as a right-angled triangle, an orthogonal triangle, or formerly a rectangled triangle, is a triangle with one right angle, meaning that its two sides are perpendicular. Trigonometry's foundation is the relationship between the right triangle's sides and other angle.
Let,
x = Longer leg of triangle
y = Shorter leg of triangle
h = Hypotenuse of triangle
Given: The length of the longer leg of a right triangle is 6inches more than twice the length of the shorter leg.
The length of the hypotenuse is 9inches more than twice the length of the shorter leg.
⇒ x = 6 + 2y
h = 9 + 2y
The given triangle is a right angled triangle.
⇒ x^2 + y^2 = h^2
(6 + 2y)^2 + y^2 = (9 + 2y)^2
36 + 24y + 4y^2 + y^2 = 81 + 36y + 4y^2
36 + 24y + 5y^2 = 81 + 36y + 4y^2
36 - 81 + 24y - 36y + 5y^2 - 4y^2 = 0
-45 - 12y + y^2 = 0
y^2 - 12y - 45 = 0
y^2 - 15y + 3y - 45 = 0
y(y - 15) + 3(y - 15) = 0
(y - 15)(y + 3) = 0
y - 15 = 0, y + 3 = 0
y = 15, y = -3
Since the length is not negative.
So, y = 15
Hence,
Shorter leg = 15 inchs
Longer leg = 6 + 2y = 6 + 2(15) = 36 inches
Hypotenuse = 9 + 2y = 9 + 2(15) = 39 inches

Data were recorded for a car's fuel efficiency, in miles per gallon (mpg), and corresponding speed, in miles per hour
(mph). Given the least-squares regression line, In(Fuel Efficiency) = 1.437 +0.541 In(Speed), what is the fuel efficiency
for a speed of 60 mph?
A)3.65 mpg
B)33.90 mpg
C)36.52 mpg
D)38.55 mpg
The fuel efficiency for the speed of 60 mph is (d) 38.55 mpg
How to determine the fuel efficiency for the speed?From the question, we have the following least-squares regression line equation that can be used in our computation:
ln(Fuel Efficiency) = 1.437 +0.541 In(Speed)
Also from the question, we have the following parameters:
Speed = 60 mph
This means that we substitute 60 mph for speed in the given equation
ln(Fuel Efficiency) = 1.437 + 0.541 In(Speed)
So, we have the following representation
ln(Fuel Efficiency) = 1.437 + 0.541 In(60)
Take the natural logarithm of 60
This gives
ln(Fuel Efficiency) = 1.437 + 0.541 * 4.09434456222
Evaluate the products
So, we have the following representation
ln(Fuel Efficiency) = 1.437 + 2.21504040816
Evaluate the sum
So, we have the following representation
ln(Fuel Efficiency) = 3.65204040816
Take the exponent of both sides
Fuel Efficiency = e^(3.65204040816)
Evaluate
Fuel Efficiency = 38.5532502162
Approximate
Fuel Efficiency = 38.55 mpg
Hence, the fuel efficiency is (d) 38.55 mpg

How to Apply Angle Relationship to Find the Value of x?Using angle relationship based on the angles involved, create an equation in each case, to enable you find the value of x.
E. 27 + 8x - 1 = 90 [the angle relationship is that they are complimentary angles].
Solve for the value of x:

8x = 90 - 26
8x = 64
x = 8
F. 7x - 44 = 75 + 63 [vertical angles are congruent]
7x = 182
7x/7 = 182/7
x = 26
I. 180 - (5x - 3 + 13x + 4) = 17 [vertical angles are congruent]
180 - (18x + 1) = 17
180 - 18x - 1 = 17
179 - 18x = 17
-18x = 17 - 179
-18x = -162

3y + 10 + 9x + 1 + 82 = 180 [angles on a straight line equals 180 degrees]
3y + 9x + 93 = 180
Plug in the value of y
3(17) + 9x + 93 = 180

Let f(x) = 5(3)x
The graph of f(x) is stretched vertically by a factor of 2 to form the graph of g(x).
Choose the equation of g(x).
Responses
g(x) = 10(3)xg(x) = 10(3)x
g(x) = 7(3)xg(x) = 7(3)x
g(x) = 2(3)xg(x) = 2(3)x
g(x) = 5(6)x
The required equation is g(x) = 10(3)x which is the correct answer would be an option (A).
The graph of g(x) is obtained by stretching the graph of f(x) vertically by a factor of 2.
Since the vertical stretch of a graph multiplies the y-coordinates of each point on the graph by a constant factor, the equation of g(x) must be obtained by multiplying the y-coordinate of each point on the graph of f(x) by 2.
In the given equation f(x) = 5(3)x, the y-coordinate of each point on the graph of f(x) is 5(3)x.
Thus, to stretch the graph of f(x) vertically by a factor of 2, we need to multiply this y-coordinate by 2 to get the y-coordinate of the corresponding point on the graph of g(x). This gives us the following equation for g(x):
⇒ g(x) = 2 × 5(3)x = 10(3)x
Therefore, the required equation is g(x) = 10(3)x.

$7.20
$7.45
$8.20
$9.45
By evaluating a linear equation, we get that the amount she spent is $ 8.20 at the coffee shop.
What is linear equation explain?
A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept is called a "linear equation of two variables," where y and x are the variables.
Assuming x refills, the price is $ 2.95 for the initial cup and $ 1.50 for each additional cup.
C(x) = $ 2.95 + $ 1.50 * x
We also know that she chose to purchase a bagel for $2.75 and that she received a $0.50 discount.
By adding these we get
C(x) = $ 2.95 + $ 1.50 * x + $ 2.75 = $ 0.50
C(x) = $5.20 + $ 1.50 * x
Now we want to find that she had 2 refills , then the total cost is
C(2) = $ 5.20 + $ 1.50 * 2
= $ 8.20
Therefore, the total cost she spend at the coffee shop = $ 8.20
