Y = 3x - 8<br>y = 4 - X​
mihalych1998 [28]

Answer:

Step-by-step explanation:

Using substitution method.

y = 3x - 8  -------(i)

y = 4 - x -------- (ii)

Substitute y = 3x-8 in equation (ii)

3x -  8= 4 - x                      {Add x to both sides}

3x - 8 + x = 4 - x +x

4x - 8 = 4         {Add 8 to both sides}

4x = 4 + 8

4x = 12    {Divide both sides by 4}

x = 12/4

x = 3

Substitute x = 3 in Equation (i)

y = 3*3 - 8

y = 9 - 8

y = 1

Find the perimeter and area of length 3cm and width 5 cm
Anni [7]
L = 5 and w = 3

Perimeter = 2(l + w)
P = 2(5 + 3)
P = 2(8)
P = 16 cm


Area = l*w
Area = 5*3
Area = 15 cm^2

If the measure of xyz is 73 what is the measure of xy <br> a.146<br> b.73<br> c.36.5<br> d.107
icang [17]
146. They are asking for the angle XY, the blue line.

For instance, imagine it is 90 deg, instead of 73, it would cut the circle in two, and XY would be 180 deg. Imagine it would be 45 degrees, it would leave a quadrant, and that's 90 deg.

So the angle * 2 (they are different angles)

I think 'TheBestBrain' thought they were asking for the supplementary angle, but I think it is the arc length angle (blue line)
