Answer:
Step-by-step explanation:
Let
x ---> the number
we know that
The algebraic expression is equal to multiply the number by 4, add 5 and equal 8
so
Solve for x
subtract 5 both sides
Divide by 4 both sides

<u>Answer:</u> The ratio that represents the cosine of ∠T is
<u>Step-by-step explanation:</u>
We are given:
UV = 56 units
VT = 33 units
UT = 65 units
∠V = 90°
Cosine of an angle is equal to the ratio of base and the hypotenuse of the triangle. ΔTUV is drawn in the image below.
Base of the triangle is UV and the hypotenuse of the triangle is TU
Putting values in above equation, we get:
Hence, the ratio that represents the cosine of ∠T is
A linear function is a function that has constant average rate of change;
Also, a relation that represents a function must have unique input and output values.
<h3>Question 11: Relations and Functions</h3>A relation may or may not represent a function.
When the domain and the range of a relation are unique, then the relation is a function.
So, the true option is (b) function
<h3>Question 12: Relations and Functions</h3>A one-to-many relation is not a function.
This is so because the domain and the range of the function are not unique
So, the true option is (c) figure 3: one-to-many.
<h3>Question 13: Variables</h3>A dependent variable is a variable that depends on other variables for its value.
In this case, the dependent variable is (b) boosts the immune system.
<h3>Question 14 and 15: Domain and Range</h3>The domain is the set of input values (i.e. the x values), while the range is the set of output values (i.e. the y values)
This means that:
- The domain of the function is: (a) {2,3,4,5,6}
- The range of the function is: (b) {4,6,8,10,12}
The graph of a linear function is represented by a straight line, and it has a constant slope or rate.
This means that:
- Graph C is a linear function
- Table B is a linear function
The fare of 3 km and 5 km are given as 35 pesos and 55 pesos, respectively.
This means that:
Table (b) represents the information
<h3>Question 19: The linear equation</h3>Start by calculating the slope (m) using:
So, we have:
The linear equation is then calculated as:
This gives
This means that:
The linear equation that describes the relationship is (c) ;
This means that x = 4.
So, we have:
Hence, the fare will be (a) 45 pesos
