Answer:

y = -3/4x - 7

Step-by-step explanation:

Parallel lines have the same slope.

Solve for y in the equation to find the slope.

x - 4y = 4x

  -4y = -x + 4x

  -4y = 3x

     y = 3/-4 x   = -3/4x    So the slope is -3/4  which is the coefficient of the

                                       x term

Substitute the slope(m) = -3/4 and point (-8, -1) into y = mx + b to solve for "b"

y = mx + b

-1 = -3/4(-8) + b

-1 = 6 + b

-1 - 6 = b

-7 = b

The equation of the new line:  y = mx + b

                                                  y = -3/4x - 7

At the city museum, child admission is $5.20 and adult admission is $8.70. On Saturday, 150 tickets were sold for a total sales
Evgen [1.6K]

Answer:

  91 child tickets were sold

Step-by-step explanation:

Let c represent the number of child tickets sold. Then the number of adult tickets sold is (150-c) and the total revenue is ...

  5.20c +8.70(150-c) = 986.50

  -3.50c +1305 = 986.50 . . . . simplify

  -3.50c = -318.50 . . . . . subtract 1305

  c = -381.50/-3.50 = 91

The number of child tickets sold that day was 91.

Pavel [41]

Answer:

(38.8%...7/10), than (47%...8/17) I didnt know if u needrd it in fraction or percent.

Step-by-step explanation:

You want to first add up everyone. So in total there are 18 people.

There is than a 38.8% chance that a independent will be picked first. 7/18.

But since one person was picked already you have to subtract 1 person from the total, so now its out of 17.

There is now a 47% chance that a democrat will be picked next. 8/17.
