Answer:

not enough information

Step-by-step explanation:

Perpendicular lines intersect at right angles. Since lines c and b are perpendicular, angles 1, 2, 3, and 4 are right angles, and each one measures 90 degrees.

Angle 2 is formed by the intersection of lines a and b. We are not told anything about the intersection of lines a and b, and we are not told anything about the relationship between lines a and c, so we do not have enough information to determine the measure of angle 2.

Method 1 :

replace x and y by their value 1 and 3

3 = 4(1) - 1 = 4-1 = 3

2(1) + 3 = 2 + 3 = 5

correct

Method 2 :

y = 4x - 1

2x + y = 5

y = 4x - 1

y = -2x + 5

y - y = 4x - 1 - ( -2x + 5 )

0 = 4x - 1 + 2x - 5

6x - 6 = 0

6x = 6

x = 6/6 = 1

y = 4x - 1

y = 4(1) - 1

y = 3

correct

At the charity drive , Jeremiah must stuff at least 350 bags with cans of food . He can stuff 4 bags in one minute,and he has 90

Ostrovityanka [42]

4m + 90 = ≥ 350
350 - 90 = 260 ÷ 4 = 65

It will take at least 65 minutes for Jeremiah to complete the task.

Replace the variable with 65 to double check.
4 (65) + 90 = 350
