What is the slope of the line that

kherson [118]

Answer:

The value of the slope is 6

Step-by-step explanation:

To get the slope of the line, we are going to make use of the slope equation

Mathematically, we have this as;

m = (y2-y1)/(x2-x1)

where (x1,y1) = (1,2) and (x2,y2) = (2,8)

Substituting these values;

m = (8-2)/(2-1) = 6/1 = 6

Answer: 18.7

Step-by-step explanation:

Find the lengths of AB, BC, and CA

AB = $\sqrt{(4-(-1))^{2} + (-1-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

BC = $\sqrt{(0-(-1))^{2} + (-3-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

CA = $\sqrt{(0-4)^{2} + (-3-(-1))^{2} }$ = 2 $\sqrt{5}$ ≈ 4.5

7.1 + 7.1 + 4.5 = 18.7

A local amusement park charges $21.50 per daily adult ticket and $14.75 per daily child's ticket. A group of 12 people paid $204

grandymaker [24]

Answer:

$x+y=12$

$21.50x+14.75y=204$

Step-by-step explanation:

Let x be the number of adult tickets and y be the number of children's tickets.

We are given that there are total 12 people. Therefore, we can set:

$x+y=12$

Moreover, we are given that an adult ticket costs $21.50 and a child's ticket costs $14.75, therefore, cost of x adult tickets will be $21.50x$ and cost of y children's ticket will be $14.75y$ . We can form the second equation by setting the total cost of tickets as:

$21.50x+14.75y=204$

Therefore, the required system of equations that could be used to find x and y will be:

$x+y=12$

$21.50x+14.75y=204$
