5+5= 10
10 time 9b is 90b
10 times -7 is -70
Then 90b-70
Answer:
A). 1/2x + 4
Step-by-step explanation:
The slope is positive since the slant is towards the right and the slope is 1/2 since using rise/run shown that it is 1/2.
Answer:
0.08
Step-by-step explanation:
5^-2 is equal to 1/25 or 0.04.
Cube root of 8 is 2.
Answer:
y = 1/2 x -2
Step-by-step explanation:
rise/run from (-6, -5) to (-4, -4) = 1/2
(rise 1, run 2)
meaning that slope (m) = 1/2
we can now rewrite our points in y=mx + b formatting:
y = mx + b
-5 = (1/2)(-6) + b
-4 = (1/2)(-4)+b
now, let's solve for b
-5 = (1/2)(-6) + b
-5 = -3 + b
-2 = b
-4 = (1/2)(-4)+b
-4 = -2 + b
-2 = b
So, the equation for our line is y = 
x- 2
hope this helps!! have a lovely day :)
When there are no special grouping symbols, math problems are solved from left to right. Although there are other important rules about the order in which you do the operations (addition/subtraction/multiplication/division) in a math expression or equation, this lesson will focus on grouping symbols. The rest of the order of operations rules will be explained in the Determining Order of Operations lesson. To help prevent confusion as you learn how to use the grouping symbols, this lesson will only use addition and subtraction.
