7x + 5 = 2x - 35
=> 7x - 2x = - 35 - 5
=> x( 7 - 2 ) = - ( 35 + 5 )
=> x( 5 ) = - ( 40 )
=> x × 5 = - 40
x = 5
Therefore the value of x in the given equation 5
Answer:
a) 8 subsets
b) 32 subsets
Step-by-step explanation:
The total number of subset of a set is known as the power of the set
Power of a set is expressed as;
P = 2^n
n is the number of element in the set
a) For a set containing 3 elements
n = 3
Power of the set = 2³
Power of the set is 8
This means that the set contains 8 different subsets
b) Cardinality of a set is the total number of element in the set
If the cardinal number of a set is 5, this means that the set contains 5elements
Hence the power of the set will be;
P = 2^5
P = 32
Hence the total number of subset for set whose cardinal number is 5 is 32
A b^3
B is x^2
I think unless you need to keep it in the fraction so x^6/x^3
Answer:
C=π×2r
Circumference is equal to pi times double the radius
Answer:
-6
Step-by-step explanation:
for f(x), x=3, which is greater than 2, choose the second function.
so, f(3)=| 3-4 | = | -1 | = 1
for g(x), x=2, which is greater than 1, choose the second function.
so, g(2)= 3*2+1 = 7
f(3)-g(2)= 1-7=-6
