Answer:y=-2x-1
Step-by-step explanation:
(1,-3) and a slope of -2
Use Formula
Y= mx +b to find b. By using the slope and point given .
M is slope
Y is -3
X Is 1
Y=mx+b
-3= -2(1)+b
-3= -2+b
-3+2=b
-1=b
Now create the equation by inputting the slope they gave you which is -2 and answer we solved for b which is -1 .
Y= -2x-1
The question is an illustration of scale drawing
The character have to travel 8.5 km in the game to visit all three destinations and return to their starting point
<h3>How to calculate the actual distance</h3>
The distance on the map are given as:
A =2 cm
B = 8 cm
C = 7 cm
The total distance on the map would be:


The actual distance between the store and the dungeon is 4 kilometers.
This means that:

So, we have:


Represent the required actual distance with x.
So, we have:

Express as fraction

Multiply both sides by 17


Hence, the actual distance travelled is 8.5 km

Answer:
When we know all 3 sides, we use Heron's Formula
area = sqrt [s *(s-a) * (s-b) * (s-c)]
where "s" is the semi-perimeter which in this case equals
s = (6 + 8 + 12) / 2 = 13
area = sqrt [13 * 5 * 7 * 1]
area = sqrt 455
area = 21.3307290077
area = 21.33 square feet (rounded)

Answer:
Number of drink = 5
Number of pretzel = 9
Step-by-step explanation:
Given:
Cost of each drink = $4
Cost of each pretzel = $5
Total money = 65
Total number of drink and pretzel = 14
Find:
Number of drink and pretzel
Computation:
Number of drink = x
Number of pretzel = 14 - x
So,
x(4) + (14-x)5 = 65
4x + 70 - 5x = 65
x = 5
Number of drink = 5
Number of pretzel = 14 - x
Number of pretzel = 14 - 5 = 9
