Answer:

Yes, it is a proportional relation.

Step-by-step explanation:

Given,

5 text messages a boy sent or received = 7 text messages a girl sent or received,

⇒ 1 text message of a boy = \frac{7}{5} text messages of a girl,

So, x text messages of a boy = \frac{7x}{5} text messages of a girl,

Let y represents the text messages of a girl for the x text messages of a boy,

\implies y = \frac{7}{5}x

Which is a line,

∵ At (0,0),

0=\frac{7}{5}(0)  ( True ),

Thus, line y = \frac{7}{5}x passes through the origin,

Hence,

y = \frac{7}{5}x shows a proportional relation.

F(x) = -7x2 + 9x - 15 and g(x) = -12x2 – 15x + 7
djyliett [7]

Answer:

{5x}^{2}  + 6x =  - 8

Step-by-step explanation:

This question is asking you to insert two equations, f(x) and g(x), into the equation g(x) - f(x). This will lead to the equation below.

{ - 12x}^{2}  - 15x + 7 - ({ - 7)x}^{2}  + 9x - 15

Now we can solve for the equation.

{ - 5x}^{2}  - 6x - 8 = 0 \\   {5x}^{2}  + 6x =  - 8
