Answer:
Part A: The equations are:
y = -1/2x + 2, and
y = 3x - 5
Part B: The solution is (2,1)
Step-by-step explanation:
Part A: There are two equations we need to find, each line is the graph of a function.Graphs are written in y = mx + b, m is the slope, which is the change in y divided by the change in x, and b is the y - intercept. To find the function of the first graph, the one going slightly down, the slope is: y goes down by one, and x increases by 2, so change in y/ change in x is -1/2. The y - intercept is where the graph goes through the point where x is 0, on this graph, the point is (0,2), the y - intercept is 2, so y = mx + b is y = -1/2x + 2
For the other equation, slope is when y increases by 3, x increases by 1, so 3/1, or 3. The y - intercept is -5, so y = 3x + (-5), or y = 3x - 5
Part B: The solution to this equation is the point where both of the functions meet, here, this point is (2,1), y is 2 and x is 1.

Answer:
15ft
Step-by-step explanation:
a^2 + b^2 = c^2
12 or 9 can equal to b or a
12^2 + 9^2 = c^2
144 + 81 = c ^2
225 = c^2
Square root of 225
15 = c
Answer:
log_3(2x+15)=2 and log_4(-20x+4)=3
Step-by-step explanation:
Plug it in and see!
#1 m=7/4 the whole equation would be y=7/4x + 3/2
