If a straight line y = mx + c passes through the intersecting point of 3x - y = 8 and x+ 2y = 5 which is perpendicular to the li

Sindrei [870]

Answer:

Point of intersection:

$3x - y = 8 - - - (a) \\ x + 2y = 5 - - - (b)$

2 × equation(b) + equation (a):

$7x = 21 \\ x = 3 \\ \\ y = 3x - 8 \\ y = 1$

Point of intersection = (3, 1)

Perpendicular line:

$3x + 6y - 11 = 0 \\ 6y = - 3x + 11 \\ y = - \frac{1}{2} x + \frac{11}{6}$

General equation of line:

$y = mx + c \\ 1 = (2 \times 3) + c \\ c = - 5$

Sarah takes home $33,000 per year from her job as a computer repair person. Her only debt obligations are a car loan payment of

VikaD [51]

To find out how much money sarah takes per month we divided her total income by 12.

$\frac{33000}{12}=2750$

Therefore, Sarah takes home $2750 per month.

To find out Sarah monthly for her home we multiply his total salary per month by .20:

$2750\cdot0.20=550$

Therefore, he pays $550 for her gome.

The total amount he pays of debt is $505.

The monthly take home pay is greater than the total amount she pays per month.

A bag of marbles contains 13 red marbles, 9 blue marbles, and 12 green marbles. If one marble is chosen at random, which is the

Pachacha [2.7K]

Answer:

B. 11/17

Step-by-step explanation:

The total number of marbles in the bag is 34

13 + 9 + 12 = 34

Then you subtract 12 from 34, since you want to know the probability of NOT getting a green marble.

12 - 34 = 22

Then you plug them into the equation:

# of outcomes that satisfy the requirement/ total # of possible outcomes

22/34 = 11/17

Hope this helps!
