Answer:

989.35

Step-by-step explanation:

you multiply 42.1 and 23.5 by taking the decimals out (don't worry you'll be putting them back) and then multiplying:

421 * 235 = 98,935

you then replace the two decimal points (because there are two decimals your going to count two decimal points into the answer) hence the answer being:

989.35

Math school is selling tickets to a play on the first day of ticket sales the school sold two adult tickets and three students t

Illusion [34]

Answer: the cost of an adult ticket is $9.

The cost of a child's ticket is $13

Step-by-step explanation:

Let x represent the price of one adult ticket.

Let y represent the price of one student ticket.

On the first day of ticket sales, the school sold two adult tickets and three students tickets for a total of $57. It means that

2x + 3y = 57- - - - - - - - - -1

The school took and $70 on the second day by selling two adult tickets and four student tickets. It means that

2x + 4y = 70- - - - - - - - - -2

Subtracting equation 2 from equation 1, it becomes

- y = - 13

y = 13

Substituting y = 13 into equation 1, it becomes

2x + 3 × 13 = 57

2x + 39 = 57

2x = 57 - 39 = 18

x = 18/2

x = 9

QUESTION 9 1 POINT Find the equation of a line that contains the points (-2,-5) and (3, -1). Write the equation in slope-interce

svet-max [94.6K]

Answer:

If only slope:

$y = \frac{4}{5}x + b$

If slope and y-intercept:

$y = \frac{4}{5}x - 6.6\\or\\y = \frac{4}{5}x - 3.4$

*both are correct answers see steps below*

Step-by-step explanation:

The equation to find the slope is $\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ .

The equation for slope-intercept form is $y = mx + b$ .

First, find the slope between two points.

$\frac{-1 - (-5)}{3 - (-2)} = \frac{4}{5}$

Keep the difference as a fraction if it can't be divided.

Next, plug in the slope value into the equation.

$y = \frac{4}{5}x + b$

If you also need to find what b is, pick a point; (-2, -5) OR (3, -1). Then fill in the equation with it's x and y values. (I'll do both points to show two different results).

Point (-2, -5):

$(-5) = \frac{4}{5}(-2) + b$
