The slope of the line that passes through (2,4) , (9,10) is 6/7
How to calculate the slope of the line?From the question, the points are given as
(2,4) , (9,10)
Rewrite the above points properly
So, we have the following ordered pairs
(x, y) = (2,4) and (9,10)
The slope of the line is then calculated using the following slope equation
Slope = (y₂ - y₁)/(x₂ - x₁)
Where
(x, y) = (2,4) and (9,10)
Substitute the known values in the above equation
So, we have the following equation
Slope = (10 - 4)/(9 - 2)
Evaluate
Slope = 6/7
Hence, the slope of the line is 6/7

Is triangle RST is an acute triangle then m/s must be?
If triangle RST is an acute triangle, then m∠S must be less than 90°.
What is Acute Traingle?
A form of triangle called an acute triangle has acute angles at each of its three internal angles. Triangles with sharp angles are also known as acute triangles. Acute triangles have different side lengths, but their interior angles are always less than 90°.
Less than 90 degree angles are referred to as acute angles.When the three interior angles of a triangle are less than 90 degrees, the triangle is said to be "acute."In light of the foregoing, if triangle RST is an acute triangle,
then,
∠R , ∠S and ∠T, all are less than 90.
A triangle that is equilateral and has all three interior angles equal and less than 90 degrees, or angles that are all 60 degrees, is an example of an acute triangle.

2x - y = 15 ---------------(2)
Add both equations

What are rational roots Class 10?
The rational root theorem, as its name suggests, is used to find the rational solutions of a polynomial equation (or zeros or roots of a polynomial function). The solutions derived at the end of any polynomial equation are known as roots or zeros of polynomials. A polynomial doesn't need to have rational zeros.
Rational root theorem, also called rational root test, in algebra, theorem that for a polynomial equation in one variable with integer coefficients to have a solution (root) that is a rational number, the leading coefficient (the coefficient of the highest power) must be divisible by the denominator of the fraction and the constant term (the one without a variable) must be divisible by the numerator.

A radioactive compound with mass 380 grams decays at a rate of 12.1% per hour. Which equation represents how many grams of the compound will remain after 4 hours?
The equation that represents how many grams of the compound will remain after 4 hours is A(4) = 380 *(1 - 12.1%)⁴
How to determine the equation?From the question, we have the following parametersa:
Mass = 380 grams
Rate of decay= 12.1% per hour
These parameters can be represented using the following exponential equation
A(n) = A *(1 - r)ⁿ
Where
n = number of hours = 4
A = Initial mass = 380
r = rate of decay = 12.1%
Substitute the known values in the above equation, so, we have the following representation
A(4) = 380 *(1 - 12.1%)⁴
Hence, the equation is A(4) = 380 *(1 - 12.1%)⁴

What is the graph of the system of inequality?
Graph of the system of inequality is a solid line and a portion of area is shaded which satisfy the condition of the inequality.
What is inequality?
When left hand side is not exactly equal to the right hand side of an equation then it is known as inequality. For system of inequality, there are four types of inequalities <, >, [tex]\le[/tex], and [tex]\ge[/tex].
Using following steps anyone can graph the inequality:
1. Get y alone on one side of a linear inequality in two variables (like x and y) before graphing it. Then, take into account the associated equation that was created by switching the inequality sign for an equality sign. This equation has a line as its graph.
2. The graph is a dashed line if the inequality is strict ( < or >). The graph is a solid line if the inequality is not strict ([tex]\le[/tex] or [tex]\ge[/tex] ).
3. The last step is to choose a point that is not on either line (typically (0, 0) is the simplest) and determine whether or not these coordinates fulfil the inequality. If so, shade the portion of the half-plane that contains that point. If not, shade the opposite half-plane.
Hence, the graph of the system of inequality is a solid line and a portion of area is shaded which satisfy the condition of the inequality.

Please Mark As BrainliestIn, a city had a population of 310,000 people. Each year since 2007, the population has grown by 4.8%.
Let t be the number of years since. Let y be the city's population.
Write an exponential function showing the relationship between t and y.
The exponential function showing the relationship between t and y is y = 310000(1.048)⁺
How to determine the exponential function?From the question, we have the following parameters that can be used in our computation:
Initial population = 310000
Rate of growth = 4.8%
These parameters can be represeted as
a = 310000 and r = 4.8%
An exponential function is represented as
y = a(1 + r)⁺
Substitute the known values in the above equation, so, we have the following representation
y = 310000 (1 + 4.8%)⁺
Evaluate
y = 310000(1.048)⁺
Hence, the function is y = 310000(1.048)⁺

Step-by-step explanation:
The upper bound of the given function is 20 while the lower bound of the given function is -8.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
As per the given function,
-2 ≤ f(x) ≤ 5
At the upper bond, f(x) = 5
[tex]\int\limits^{3}_{-1} {f(x)} \, dx[/tex] = [tex]\int\limits^{3}_{-1} {5} \, dx[/tex]
⇒ 5(3 + 1) = 20
At the lower bond f(x) = -2
[tex]\int\limits^{3}_{-1} {f(x)} \, dx=\int\limits^{3}_{-1} {-2} \, dx[/tex]
⇒ -2(3 + 1) = -8

amounts with both will be equal. Instead, if Yamini
gives 20 to Shivani, the amount with Shivani would
become twice the amount left with Yamini. What is
the amount with Shivani?
Answer:
$300
Step-by-step explanation:
S = amount of $$ Shivani currently has
Y = ... Yamini currently has
1. If Shivani gives 60 to Yamini, the amounts with both will be equal:
S - 60 = Y + 60
2. if Yamini gives 20 to Shivani, the amount with Shivani would become twice the amount left with Yamini: 2(Y-20) = S+20
3. Simplify both equations and solve the system:
S = Y + 120
S = 2Y - 60
Y + 120 = 2Y - 60 ⇒ Y = 180
S = 180 + 120 = 300
