Answer: Y = 4
the output is 4
Step-by-step explanation:
substitute the given input value, 3, for x and solve
Y= 10 -2x
Y = 10 -2(3) multiply -2 × 3 to get -6
Y = 10 -6 . subtract
Y = 4
Answer:
27 pieces
Step-by-step explanation:
1) first, multiply 6 times 3 (6×3=18)
2) 1 ft = 12 in. so you multiply the 18 by 12 (18×12=216)
3) now you divide the 216 by 8 (216÷8=27)
Step 1: Find the slope:
To find the slope, find two points on the graph and count the “rise over run” between the points.
Two points here are (0,-1) and (2,1). To get from (0,-1) to the other point, you need to go “up 2” and then “right 2”. This means your slope is 2/2 or 1.
Step 2: Find the y-intercept:
We can see the y-intercept is (0,-1) on the graph. We’ll use the “-1” from that point for our equation.
Step 3: Put it all together:
The slope-intercept form is y=mx+b, where m is the slope and b is from the y-intercept.
Putting Step 1 and Step 2 into play, we have:
y = x - 1
Note: since m=1, we don’t need to write y = 1x -1. That 1 on the 1x is unnecessary.
The answer would be C. aroma
