Step-by-step explanation:
4-1
Point-Slope:
y+16=-1/26*(x-19)
Finding the regular slope:
m=1/-26=0.03846
If Connie spent $26 on 8 books, The number of hard covers she buy is 5 hard cover.
<h3>
Number of hardcover bought</h3>
Let h represent hard cover
Let p represent paperbacks
Formulate an equation
h + p= 8.......(1)
4h + 2p= 26......(2)
Multiply equation (1) by -2
-2h + -2p = -16
<u> 4h + 2p = 26</u>
2h + 0p =10
2h = 10
Divide both side by 2h
h=10/2
h =5 hard covers
Paper backs
P=5-2
P=3 paper backs
Therefore If Connie spent $26 on 8 books, The number of hard covers she buy is 5 hard cover.
