Let (a) be the first cat
let (b) be the second cat
a +b=11kg-----(1)
a=b+1500g⇒(1.5 kg)-------(2)
so now u have a system of two unknowns
a=11-b
substitute a in (2)
11-b=b+1.5
11-1.5=2b
2b=9.5
b=9.5/2=4.75
subs. b in (1)
a+b=11
a+4.75=11
a=11-4.75=6.25
so cat (a) is 6.25 kg
and (b) is 4.75 kg
hope I helped
The answer is c. y=4x + 3
Answer:
Implicit function
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given y² + x - 3=0 ...(i)
Differentiating equation (i) with respective to 'x', we get
⇒ 
⇒
Divide by 2.5: 2.5(12.75x+24.50)/2.5 = 188.75/2.5 .
simplify: 12.75x + 24.50=75.5 .
subtract 24.50 from both sides
simplify: 12.75x = 51 .
x= 4.
Answer:
x=12
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
9^2 + x^2 = 15^2
81 + x^2 = 225
Subtract 81 from each side
x^2 =225-81
x^2 =144
Take the square root of each side
sqrt(x^2) = sqrt(144)
x=12
