Answer:
y = 3 · 2ˣ
Step-by-step explanation:
Exponential function is:
y = abˣ
Plug in the points:
⅜ = ab⁻³
12 = ab²
Solve the system of equations. Start by dividing the second equation by the first:
12 / ⅜ = (ab²) / (ab⁻³)
32 = b⁵
b = 2
Plug into either equation to find a:
a = 3
Therefore:
y = 3 · 2ˣ
Answer:
The cost of 1 burger is $60 (600 ÷ 10)
The cost of 15 burgers is 900 (15 x 60)
Y= 2x-3/4
M is the slope
B is the y-intercept
Answer:
1/2x-7
Step-by-step explanation:
Add 3/8x and 1/8x to get 4/8x which is the same as 1/2xThen add the integers: -2 + -5 = -7.

Answer:
2√13
Step-by-step explanation:
The distance formula is useful for this. One end of the vector is (0, 0), so the measure of its length is ...
d = √((x2 -x1)² +(y2 -y1)²) = √((6 -0)² +(-4-0)²)
= √(36 +16) = √52 = √(4·13)
d = 2√13 = |(6, -4)|
