Hey!
Let p = cost of a pen
<span>Let n = cost of a notebook </span>
<span>The info in the question leads to two equations: </span>
<span>1) 2p + 3n = 5.55 </span>
<span>2) p + 2n = 3.50 </span>
<span>Multiply equation 2) by 2 to get the new system of equations </span>
<span>1a) 2p + 3n = 5.55 </span>
<span>2a) 2p + 4n = 7.00 </span>
<span>Subtract equation 1a) from equation 2a) to get </span>
<span>n = 1.45 ...................... that's the cost of one notebook </span>
<span>~~~~~~~~ </span>
<span>To check, you could go on to figure out p, which turns out to be 0.60 . Put in those values of n and p into the original equations to verify.</span>
Hope this helps! ~Nadia~
1. <span>4x – 20 = 5y
so 5y = </span><span>4x – 20
divide both sides by 5
y = (4/5)x - 4
2. x-intercept is at y=0
so (4/5)x - 4 = 0
x = 5
so it is (5,0)
3. y-intercept is at x=0, y = 0 - 4 = -4
so it is (0,-4)
