Answer:
Step-by-step explanation:
When the lines intersect, the point of intersection is the only point that the two graphs have in common. So the coordinates of that point are the solution for the two variables used in the equations.

HEYAA!!!!!
OPTION D
To get the additive inverse of a positive number you put a minus in front of it and to get the additive inverse of a negative number, you remove the minus to make it a positive number.
because when u see the equation u can see it is -3-(-6)
which if u solve it the answer is -3+6=3
so the correct option is (D)

Answer:
The equation is;
y = -3/4x + 12
Step-by-step explanation:
The general form for the equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
With respect to this question;
4/3 is the slope and 1 is the intercept
If two lines are perpendicular, then the product of their slopes is -1
Mathematically;
4/3 * m2 = -1
m2 = -3/4
So to find the equation of this second line, we use the point slope form
This is;
y-y1 = m(x-x1)
y-4 = -3/4(x + 8)
y- 4 = -3/4x + 8
y = -3/4x + 12
Answer:
Matthew payed .63 (rounded .625) cents for each toothbrush while Jon payed .72 cents per toothbrush
Step-by-step explanation:
$5 = 8 toothbrushes
$18 = 25 toothbrushes
5 / 8 = .625
18/25 = .72
