Asap im giving away free points plus brainliest for correct
which answer describes the graph of the system of equations?
{y = 4-x
{2y = 8 - 2x
a. the point of intersection is (0, 4).
b. the point of intersection is (4, 0).
c. the lines are parallel.
d. the lines coincide.

D. The lines coincide.

Step-by-step explanation:

Since, a system of two lines and ,

Has a point of intersection, if,

Has infinitely many solution ( i.e. lines are coinciding ), if,

Has no solution ( i.e. lines are parallel ), if,

Here, the given system of equations,

y = 4 - x ⇒ x + y = 4,

2y = 8 - 2x ⇒ 2x + 2y = 8

Thus, by the above explanation,

The given lines coincide.

Option 'D' is correct.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones
