Ok so for number 5, AB is proportional to BC just like PQ is proportional to QR. AB = 9, BC = 15, PQ = 3, and QR = x. 9/15 = 3/x. Cross Multiply: This gives you - 9x = 45. Divide both sides by 9, and you get x = 5. QR = 5
(X)+2(x+1)=26
3x=24
X=8
Y=x+1
Y=8+1
Y=9
The two numbers are 8 and 9
48 all you had to do was out it in a calculator that's what I did
Function y = -2x + 5:
slope of -2
y intercept at 5
x intercept at 2 1/2
function y = x
slope of 1
y intercept at 0
x intercept at 0
The same as the greatest number that can be written
with 10 binary bits: <u>1,024</u>
