Basically either subsitute or solve
I will simplify to make easier work
so PEMDAS
Parenthasees
Exponents
multiply or divide whichever comes first
add or subtract whichever comes first
9 times 8=72
I will assume that x2=x^2 or x squared so left is simplified
x^3+x^2 so
72-2x+x^2<u>></u>x^3+x^2
subtract x^2 from both sides since they cancel each other out
72-2x <u>></u> x^3
add 2x to both sides
72 <u>></u> x^3+2x
factor
72 <u>></u> x(x^2+2)
now subsitute 7,6,5,4
if x=4 then
4(4^2+2)=4(16+2)=4(18)=72
72 <u>></u> 72
true
since all the other numbers are smaller, the only sentence that will work is 7 or A
the answer is A 7
Answer:
6
Step-by-step explanation:
10x6=60-2=58
Answer: A. 88 turtles
To find this, multiple 110 x .80
This is easier than multiplying 110 by .20 because you don’t have to subtract.
110 x .80 = 88
Given the function:
To sketch the graph, we calculate some points:
For ease of calculation, pick values of x that are perfect squares.
Similarly:
Similarly:
Next, draw a line joining the points (0,5), (4,7) and (9,8) as done below:
Hi!
The correct answer is B. The value of M is a product of N and a factor that does not depend on N.
That is true because the relation is : M(t) = N * (1+r)^t , N is N and (1+r)^t is a factor that does not depend on N.
Also, because none of the other answers is true, it makes easier for B to be the one true answer, explanation:
A. The initial value is (1+r) - WRONG, the initial value is N, it says that
C. The function is linear - WRONG, we have exponential growth here, because of the factor (1+r)^t
D. N increases each month - WRONG, N is the initial number of members and it does not change.
Hope this helps!
