I'm solving your system by substitution.
2x-4=5, 5x+4y =2
Step# 1: solve for x
2x - 4+ 4= 5 + 4( add +4 to both sides)
2x = 9
x = 9/2
Step# 2: solve for y
5(9/2) + 4y = 2
4y + 45/2 = 2
4y 45
y = 45/4 = 11.25
Answer:
First option, y = 2x - 3
Step-by-step explanation:
Remember the formula for a line is y=mx+b, where m is slope (slope = rise/run) and b is y-intercept (y-intercept is the point that crosses the y-axis)
Since the line on the graph crosses the y-axis at -3, that will be the y-intercept. Starting from that point, find another point. In this case you go upwards 2 units and to the right 1, so your slope will be 2/1 or just 2 .
Hope this helped :)
Plug in the given numbers (x) to the equation.
For example, let's take the first value it gives us.
-10(-2) +y=4
20+y=4
y=-16
Then you would put that on the table, and plug in the next value(s).
Hope this helped!
its 90 measurement CBG (I think) is corresponding to measurement DAE
Cone's volume is third of cylinder's volume, so 321*1/3=107 cubic units. Answer A. is correct.
