Answer:
4/3 kg
Step-by-step explanation:
Let x represent a half brick, let y represent a 1 brick.
We know that 1 brick and 1/2 brick weigh 1 kg. so we represent this as
We know that obviously x is half of y. so
Subsitur this for x.
This means one block weight 2/3 kg. So how much 2 weigh.
Answer:
<u><em>y = (1/2)x + 1</em></u>
Step-by-step explanation:
y=mx+b, where m is the slope and b the y-intercept (the value of y when x = 0). We are given y = -2x + 2 as the reference line and are asked to find a line that is perpendicular to it. (We'll get to the (2,2) thing later).
A perpendicular line has a slope that is the negative inverse of the reference line slope, which in this case is -2 (the m). The negative inverse of -2 is -(-1/2) or (1/2), This measn the perpendicular line will have the form:
y = (1/2)x + b
The complication is that we want this new line to go through point (2,2). Easy. Just substitute (2,2) in the aboove ea=quation and solve for b:
y = (1/2)x + b for (2,2)
<u>2</u> = (1/2)<u>2</u> + b
b = 2 - 1, b = 1
The equation of the line perpendicular to y = -2x + 2 is <u>y = (1/2)x + 1,</u>
