In any given equation, a positive or negative number that isn't multiplied by a variable is called "b", or "y-intercept." Seeing as y-5 (f(x) is the same as y) isn't an equation, it probably means you need to add 5 to both sides to isolate y.
you end up with y=5, a horizontal line in which every "y" value in every set of points is equal to 5
Ex: (1,5),(2,5),(3,5)...
this means that your parent function of y=0 has a vertical shift upwards of five. hope I could help :)
So you basically plot a point of the y axis on 7 then since the slope is -3x you have to go down 3 and to the right 1 and keep going then you have to do the same but opposite, go up 3 times and to the left 1 unit.
Answer:
HERE FOR POINTS SORRY
Step-by-step explanation:
Answer:
The system of equations are;
4.75t + 7.50b = 790
t = 2b
where t is the number of tacos and b is the number of burritos
Step-by-step explanation:
In this question, we are concerned with writing the system of equations that could help us determine the number of tacos and burritos sold.
Firstly, we start with defining variables. Let the number of tacos sold be t and the number of burritos sold be b
*there we twice as many burritos as tacos sold. What this simply means is that the number of tacos sold is twice the number of tacos.
Mathematically that could be written as ;
t = 2b ••••••••••(i)
Now, let’s work with the revenue;
Each taco is sold at $4.75 and he sold a total of t tacos. The revenue realized from tacos sold is thus $4.75 * t = $4.75t
The money realized from selling b burritos at $7.50 each would be $7.50 * b = $7.50b
The addition of both of these will give the total revenue of $790
Thus, we have;
4.75t + 7.50b = 790 ••••••• (ii)
