Answer:
x=5,y=3
Step-by-step explanation:
the first step is to decide whether you want to substitute y and find x, or substitute x and find y.
(it doesn't matter which way you will choose.If you do the math correctly you will get the correct answer,one way or another).
for example, let's substitute y into the first equation:
x=17-4*(x-2)
so now,we will organize the equation:
x+4x=17+8
5x=25/(÷5)
x=5
now we will substitute x with 5 in the second equation(or the first one,it doesn't matter)in order to find y:
y=5-2
y=3

Answer:
Step-by-step explanation:
Harvey rides his bike at an average speed of 12 miles in 1 hour, 24 miles in 2 hours, and so on. Let h be the number of hours he rides and d be distance traveled. Write the equation for the relationship between distance and time in point-slope form.
----
You have three points relating time and distance:
(1,12),(2,24),(3,36)
-----
The slope for your equation would be (24-12)/(2-1) = 12/1 = 12
-------------------------------
The intercept is the distance you would travel in no time; that would be zero.
---------------------------------
The equation is: distance = 12(time)
d = 12t
You need to multiply 25 by 18 to find the total.
25 x 18 = 450.
