Answer:
Step-by-step explanation:
a. To solve for "y" you want to isolate the variable. What this means is you want to keep "y" on its own. To do this first we will subtract 2x from the equation making 4y = 36 - 2x. Next, we will get rid of 4 to do this divide 4 from both sides. y = (36 - 2x)/4
*I have to go in a bit so sry for no explenation*
b. h = 2a/b
c. x = 1/4y + -3/4
If you divide 20 acres into 1/4 sections you'll get
20 ÷ 1/4 sections. When you divide fractions, you just multiply the reciprocal.
20 ÷ 1/4 =
20 × 4/1 = 80 sections

Step-by-step explanation:
The first part of the function, f(x) = -2x (for x < -1), is only graphed correctly in the first and third graphs.
The second part of the function, f(x) = -1 (for -1 ≤ x < 2) is only graphed correctly in the first graph, which also correctly graphs the third part of the function,
The appropriate choice is the first graph.
