Answer:
x = -15
Step-by-step explanation:
Because -15/-5 = 3, 3+4 =7
10-3=7
7=7
Answer:
f(3) = 1/(3)^2-3
Step-by-step explanation:
To solve for when x=3, we simple replace x with 3
f(3) = 1/(3)^2-3
Answer: 78 miles
Step-by-step explanation:
Hi, since the distances form a right triangle ( see attachment) we have to apply the Pythagorean theorem:
c2 = a2 +b2
Where c is the hypotenuse (the longest side) and a and b are the other two sides of the triangle.
In this case the hypotenuse is the distance from Jonestown to Brighton (x)
Replacing with the values given:
x2 = 30^2 + 72 ^2
x2 = 900+5184
x2=6084
x = √6084
x = 78 miles
Step-by-step explanation:
1. 3x + 4 = 19
3x = 15
x = 5
2. 7 + 2x = 15
2x = 8
x = 4
