F(x)=2x(x-3)/(x+4)(x+3), Creation of the hole: have 3 as a solution for both numerator and denomenator
Formation of a vertical asymptote at -4: have the denominator equal to zero when plugging in -4 such that the denominator equals to zero,
horizontal asymptote: have the highest degree of numerator and denominator equal and the quotient of their coefficient equal to 2(ever wonder why there is an "x" in the numerator? It is to set the highest degree of the numerator and denominator equal to each other.
If you need more explanations, ask, glad to help.
Perimeter is equal to 2l+2w, or 2 times the length plus 2 times the width.
So to solve for this you'd take 2(6.5) + 2(4.23).
2(6.5)= 13
2(4.23)= 8.46
13+8.46= 21.46 meters.
Based on this, the answer is C.
-8-5b+7+5b
add +5b to -5b to get 0.
-8+7 = -1
Answer is -1.
1/4 of the total girls = 16
1/4x = 16
x = 16 * 4
x = 64 girls
1/8 of the total boys = 7
1/8x = 7
x = 7 * 8
x = 56 boys
for a total of (64 + 56) = 120 students <===
Answer:
y = 25
Step-by-step explanation:
Given that the quantities are proportional then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 10 when x = 6
k = 
= 
= 
y = x ← equation of proportion
When x = 15, then
y = × 15 = 5 × 5 = 25
