How do I do this with explaination too
1 answer:
Answer:
27
Step-by-step explanation:
1. Using PEMDAS, you would start with all numbers inside the parentheses
2. Next inside the parentheses are exponents
3² = 3*3 = 9
2³ = 2*2*2 = 4*2 = 8
2² = 2*2 = 4
3. Go back inside the parenthese now that everything is multiplied out
= 9* ( 12)/4 = 108/4
4. Simplify the fraction by dividing 108 by 4
108 ÷ 4 = 27

Answer:
<u><em>The equation is y = (1/2)x + - 3.5</em></u>
Step-by-step explanation:
We look for an equation with the form y = mx + b, where m is the slope and b the y-intercept.
We're given the slope, (1/2) which we can use for m:
y = (1/2)x + b
We are told the line goes through (5,-1). We need a value of b that will move the line to include this point. Do that by substituting the values:
x = 5, and y= -1
y = (1/2)x + b
-1 = (1/2)*5 + b
-1 = (2.5) + b
- 3.5 = b
<u><em>The equation is y = (1/2)x + - 3.5</em></u>
