jim ordered a sports drink and three slices of pizza for $8.50. His friend ordered two sports drink and two slices of pizza for
inna [77]

Answer:

  • drink cost: $1.75
  • slice of pizza cost: $2.25

Step-by-step explanation:

Let d and p represent the costs of a drink and a pizza slice, respectively. The two orders have a value ...

  d + 3p = 8.50

  2d + 2p = 8.00

Subtracting the second equation from twice the first gives ...

  2(d +3p) -(2d +2p) = 2(8.50) -(8.00)

  4p = 9.00 . . . . . simplify

  p = 2.25 . . . . . . divide by 4

Solving the first equation for d and putting in the value, we have

  d = 8.50 -3p = 8.50 -3·2.25 = 8.50 -6.75

  d = 1.75

The cost of a drink is $1.75; the cost of a pizza slice is $2.25.

The system crosses at the point (3, 4). How many solutions will the system have?
vagabundo [1.1K]
For this case suppose that we have a linear system of equations of the form:
 ax + by = c
 dx + ey = f
 The solution of the system is an ordered pair of the form:
 (x, y)
 That is, both lines intersect at a point.
 The point of intersection in this case is:
 (3, 4)
 Therefore, the system has one solution.
 Answer
 
the system will have:
 
one solution

Complete the equation of the lines whose slope is 5 and y-intercept is (0,4)<br>y = ?
Dimas [21]

Answer:

y = 5x + 4

Step-by-step explanation:

y - 4 = 5(x - 0)

That is point-slope form. I'm not sure if you want it in slope intercept form, but slope intercept form of the equation is -

y = 5x + 4
