Answer:
0.3
Step-by-step explanation:
(7.4-1.1) - (2.1-8.1)
Lets start with (7.4-1.1)
Step 1:
(7.4-1.1) =6.3 (All you do is subtract 7.4-1.1 and it gives you 6.3)
Step 2: Lets do (2.1-8.1)
(2.1-8.1)= -6 (2.1 minus 8.1 gives you -6 because 2.1 is smaller than 8.1 so it will give you a negative)
Step 3: Subtract
6.3-6
So your answer would be 0.3

Hi there!
To subtract this, we can only subtract like terms. That means we only subtract 7x^2 and 5x^2, 4x and 10x, and -9 and -5. It might make more sense after the work below:
7x^2 - 5x^2 = 2x^2
4x - 10x = -6x
-9 - -5 = -4
So, the answer is 2x^2 - 6x - 4
Hope this helps!
Answer:
161
Step-by-step explanation:
7(23) = 7(20 + 3) =
Distribute
7*20 =140
7*3 =21
140+21 =161
Answer:
y = 6x - 2
Step-by-step explanation:
slope intercept form is y = mx + b
m = slope
b = y-intercept
They give us the slope (m) which is 6 and the y-intercept (b) which is -2. PLug it into the equation
y = mx + b
y = 6x - 2
