There’s 10 vases. Each one needs 3 roses and 8 carnations. So 3(10) is how many roses and 8(10) is how many carnations. The equation is 10(3x+8y) x being roses and y being carnations.
Answer:
y = -2x +6
second equation is incorrect.
because there are 2 equal signs in that equation
Step-by-step explanation:
The product of all the values of a, such that f(a)=f(2a) is -1/2
<h3>Functions and expressions</h3>
Given the function below;
f(x)=1/x + x
f(a) = 1/a + a
f(2a) = 1/2a + 2a
If f(a) = f(2a), hence;
1/a + a = 1/2a + 2a
Collect the like terms
1/a - 1/2a = 2a - a
2-1/2a = a
1/2a = a
Cross multiply
2a² = 1
a² = 1/2
a = ±√1/2
The values of a are √1/2 and -√1/2
Product = -√1/2 * √1/2
Product = -1/2
Hence the product of all the values of a, such that f(a)=f(2a) is -1/2

The pertinent formula is i = p*r*t. Here, i = $6,300, r = 0.07 and t = 5 yrs.
We want to solve this for the principal, p. Since i = p*r*t, p = i / (rt). In this case, the principal was:
p = $6,300 / [0.07*5] = $6,300 / 0.35 = $18,000
Round it up so you do 11x36
