First add 45 and 55 because sum means addition. 45+55=100 and teiple means multiplication and 3x100= 300 hope this helped :)
Answer:
He should have divided 12 ÷ 3 first.
Step-by-step explanation:
Following PEMDAS/BODMAS, the first step is solving equations in parentheses. Since the parentheses contain a multi-step equation, Jay needs to follow PEMDAS for inside the parentheses as well. Instead of adding 3+12 first, he should have done division first (12 ÷ 3).
How the problem should be solved:
-3 × (3 + 12 ÷ 3) - 4
-3 × (3 + 4) -4
-3 × 7 - 4
-21 - 4
-25
Answer:
(x) = 
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 5x + 4 ( subtract 4 from both sides )
y - 4 = 5x ( divide both sides by 5 )
= x
change x to (x) and y back to x, thus
(x) =
Answer:
0.63
Step-by-step explanation:
Only 0.634 matters. If the thousandths place is 5 or greater, it'd be 0.64
Answer:
1.) Arithmetic sequences are modeled with linear functions because it is a linear series
2.) Geometric sequences are modeled with exponential functions because their value increases exponentially
Step-by-step explanation:
1.) Arithmetic sequences are linear functions. While the n-value increases by a constant value of one, the f (n) value increases by a constant value of d, the common difference.
Arithmetic Sequence is one where you add (or subtract) the same value to get from one term to the next.
2.) An exponential function is obtained from a geometric sequence by replacing the counting integer n by the real variable x. Geometric sequences (with common ratio not equal to −1, 1 or 0) show exponential growth or exponential decay, as opposed to the linear growth (or decline) of an arithmetic progression such as 4, 15, 26, 37, 48, … (with common difference 11).
This shows that Geometric series grow or decays (reduces) exponentially; this is due to their common ratio (r)
