Answer:
13) 25 and 17
14) cupcakes = $5
brownies = $3
Step-by-step explanation:
13) you can set this up as equations
so x + y = 42
x-y = 8
solve simultaneously by subtracting from each other
2y = 34
y= 17
if y = 17
42 - 17 = 25 = x
14) set up as equations again
Ben 7c + 10b = 65
franklin 7c +7b = 56
subtract from eachother
3b = 9
b = $3
7c + 10(3) = 65
7c = 35
c = $5
Answer:
Perpendicular
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes
-2/3 negated is
2/3
The reciprocal (flip the numerator and denominator) of 2/3 is
3/2
So, the lines are perpendicular

Answer:
Q(t) = 14.8(1.392)t
Explanation:
Let us consider a decay model defined as Q=abt, where t is the time, b is the rate, a is a constant and Q is the quantity at time t
Now, at t=0 quantity = 14.8
Substituting t=0 in our model,
14.8=a
Now, at t=1, quantity = 20.61
Substituting t=1 in our model,
20.61 = 14.8b1,So,
b= 1.392
At t=2,
Q = 14.8(1.392)2 = 28.66 which satisfies our table,
at t=3,
Q = 14.8(1.392)3 = 39.92 which again satisfies the table value
Answer:
Ok so 1. I am in AP Calculus BC and I legit just fully learned how to do exponents (I had a rough year in algebra 1 lol) so don't feel bad. And 2. It's really simple. When you multiply exponents you so just add them so x^2 * x^3=x^5. This makes sense visually since x^3 is x*x*x and x^2 is x*x and when you multiply that out you get x*x*x*x*x. Division is also pretty simple and all you have to do is subtract them. (There is a reason for this but its not important but I'll explain it anyways. Basically when you divide it is the same thing as multiplying by a negative exponent so x^3 / x^2 = x.) When you have multiple variables all you have to do is combine like terms so if you have something like xy^2*xy^4 you would get (x^2)(y^6). As for your problems, here:
