60v = $15
60v/60 = $15/60
v = 0.25
The original value of the baseball card is $0.25
Answer:
x = -5
x = -12
Step-by-step explanation:
- 7x - 60 = x^2 + 10x
add 7x to both sides
x^2 + 17x = -60
add 60 to both sides
x^2 + 17x + 60 = 0
factorise quadratic
(x + 12) (x + 5) = 0
<em>x = -12</em>
<em>x = -12x = -5</em>
Answer:
<em>4x-3y=8</em>
<em>Simplifies to x=3/4y+2</em>
2x+5y=-9
Simplifies to -5/2y+-9/2
Answer:
Step-by-step explanation:
Well you have to first look at the chart to see if it fits what Ariel claimed.
There is actually a higher percent of students with no siblings that have pets if you look at the total for students with no siblings. If you look at the number though 45>39. Also her claim is not justified because the percentage is lower for students with siblings. Thanks for the 50 points ;) If you have any questions just ask
Answer:
The exponential parent function with base two is
f(x)=2^x
where x∈(-inf,inf).
when x-> -inf, f(x)-> 0
similarly, when x-> inf, f(x)-> inf
so the range of f(x) is (0,+inf).
