Second option since its a sun moon and earth model
26.) 3(2)² - 8(-3)²
= 3*4 - 8 + 9
= 12 - 8 + 9 = 13
27.) I 7 - 4(2) I
7 - 8 = -1, but since this is absolute value, which is a number's distance from zero, your answer for 27 would be a positive one.
28.) (-2)² + 2(-3 * 1)
= 4 + 2(-3)
= 4 + (-6) = 4 - 6 = -2
29.) 7(-4)² + 5 / 4(1) - (-5)
=7 * 16 + 5 / 4 + 5
= 112 + 5 / 9 = 117/9 = 13
30.) Product: the result of a multiplication problem
Increased by: multiplied by
3(n * 7)
31.) 2n - 1
Answer:
B. (2, 3)
General Formulas and Concepts:
<u>Algebra I</u>
- Solving systems of equations using graphing
Step-by-step explanation:
<u>Step 1: Define system</u>
y = x + 1
y = -1/2x + 4
<u>Step 2: Identify Solution</u>
The solution to the systems of equations when graphed will be where the 2 lines intersect. According to the graph, the 2 lines intersect at (2, 3).
1. 4i x -10i = -40ii
ii = i^2 = -1
-40*-1 = 40
2. -6-9 = -15
5i- - 5i = 5i + 5i = 10i
answer = -15 +10i
3. raise both sides to the 3rd, and solve for x. x = -12
4. the equation would be x^2+36 =0
Answer:
red balls = 5
blue balls = 5
total balls = 5 blue+5 red
= 10
