The length is 12, because if it's 9 inches wide it has two sides of 9 inches which is 18. Then subtract that from the intial value 42 to get 24. After, you divide 24 by 2 due to there being 2 sides of the box and 24 is the sum of both sides. Hopethis helps!
28 divided by 4 = 7
so do 7 * 5 which is 35 so they make 35 cookies in 5 seconds
Step-by-step explanation:
you put the values in place of the variable names and calculate.
y² + x + y
(-4)² + -3 + -4 = 16 - 3 - 4 = 16 - 7 = 9
Answer: y<1x-2
Step-by-step explanation:
Find some coordinates on the line to write a slope intercept form equation for the line and turn it into inequality.
First we need to find the slope and the y-intercept. The y intercept is when x is 0 and as we can see it already indicates that the y intercept is -2 .
(0,-2)
(2,0) Use these points o the find the slope.
0- 2 = -2
-2 -0 = -2
-2/-2 = 1 The slope is one so the equation will be y = 1x - 2 But since this is not an inequality we have to change the equal to sign to an inequality sign.
Looking at the line, it is a dashed line so the inequality sign will be > or <
The painted side of the graph represents the solutions of the graph and that is all underneath the graph so the inequality will be y < 1x-2
