Answer:
2x + y = 26
Step-by-step explanation:
The standard form of a linear equation is
A
x + By = C.
Simplify -2(x - 8)
Multiply -2 by -8
y - 10 = -2x + 16
2x + y - 10 = 16
Add 10 to both sides.
Add 16 and 10
Answer= 2x + y = 26
d = 3 , a₁₂ = 40 and S
= 7775
In an arithmetic sequence the nth term and sum to n terms are
<h3>• a
= a₁ + (n-1)d</h3><h3>• S
=
[2a + (n-1)d]</h3><h3>
where d is the common difference</h3><h3>a₆ = a₁ + 5d = 22 ⇒ 7 + 5d = 22 ⇒ 5d = 15 ⇔ d = 3</h3><h3>a₁₂ = 7 + 11d = 7 +( 11× 3) = 7 + 33 = 40</h3><h3>S₁₀₀ =
[(2×7) +(99×3)</h3><h3> = 25(14 + 297) = 25(311)= 7775</h3>
Hello!
Significant digits are defined as all digits that determine the value of a number, excluding any zeros that act as placeholders. Let's find the number of significant digits in each option individually:
A. 0.0009462 = 4 significant digits (the zeros are placeholders)
B. 1.000150 = 7 significant digits
C. 2.0145 = 5 significant digits
D. 3.01255 = 6 significant digits
Looking at the list above, we can see that Option B has the greatest number (7) of significant digits.
The answer is Option B.
I hope this helps!
