I think that the answer is the 2rd choice on the 2nd picture.
Hope this helps!! :-)
Factorising the polynomial 5x³ + 35x² + 6x + 42, the value of A is 6.
<h3>Factorisation of polynomial</h3>
Factorising a polynomial simply means to decompose the polynomial into a product of two or more polynomials.
Therefore, let's factorise 5x³ + 35x² + 6x + 42 and find the value of A
(5x² + A)(x + B)
Therefore,
5x³ + 35x² + 6x + 42
5x³ + 6x + 35x² + 42
x(5x² + 6) + 7(5x² + 6)
Therefore,
(5x² + 6)(x + 7)
Therefore, the value of A is 6

Answer:
There's no proportional relationship between number of laps and minutes.
Step-by-step explanation:
The graph given above is a straight line graph, however, it does not cut across the point of origin (0, 0). As a result of this, it would be difficult to get a constant of proportionality, as you'd likely get different constant of proportionality between different points on the line. Thus, the ratio of y and x for each set of points may vary.
So therefore, the relationship between the x and y cannot be proportional.
We can conclude that the graph does not represent a proportional relationship between number of laps and minutes.
Answer:
The graph would be -1x + 5
and the function is -1.5 + 6
Its asking for the initial value
so 6 > 5
so function B is correct
Answer:
x = 5/3
Step-by-step explanation:
You ALWAYS want your term to be by itself!! So what you need to do is move your constant away from it.
Step 1: Adjust as needed, subtract 10 from both sides of your equation. It should end up like this.
-3x = 5 - 10
Step 2: Solve as needed before continuing equation.
-3x = -5
Step 3: Now you need to get your term by itself. You should divide -3 on both sides of your equation so you should get something like this.
x = -5 / -3
Step 4: You're basically done now! Just simplify! NEGATIVES CROSS EACH OTHER OUT!!!
x = 5/3 OR 1.6
<em>KEY:</em>
<em>Negative and Negative = Positive</em>
<em>Negative and Positive = Negative</em>
<em>Positive and Positive = Positive</em>
