Grant earns $5 for each magazine he sells.Write an equation in two variables showing the relationship between the number pf maga

slega [8]

Answer:

$A=5m$

Grant will make $60 from selling 12 magazines.

Step-by-step explanation:

Let m represent number of magazine sold and A represent amount of money earned.

We have been given that Grant earns $5 for each magazine he sells. So amount earned from m magazines would be 5 times m that is $5m$ dollars.

Now, we will equate total amount earned by Grant with A as:

$A=5m$

Therefore, our required equation would be $A=5m$ .

To find the amount earned by Grant by selling 12 magazines, we will substitute $m=12$ in our equation as:

$A=5(12)$

$A=60$

Therefore, Grant will make $60 from selling 12 magazines.

What are the zeros of the following quadratic equation: y = 6x2 - 17x - 3

Mama L [17]

Answer:

$\displaystyle x=-\frac{1}{6}, 3$

Step-by-step explanation:

Hi there!

$y = 6x^2 - 17x - 3$

Factor by grouping:

$y = 6x^2 - 18x+1x - 3\\y = 6x(x- 3)+1x - 3\\y = 6x(x- 3)+(x - 3)\\y = (6x+1)(x- 3)$

Let y=0. Apply the zero product property:

$0 = (6x+1)(x- 3)$

$6x+1=0\\6x=-1\\\\\displaystyle x=-\frac{1}{6}$

AND

$x-3=0\\x=3$

I hope this helps!
