20y+5x≤100 divide all terms by 5
4y+x≤20 subtract x from both sides
4y≤-x+20 divide both side by 4
y≤-0.25x+5
So just in simplest terms, the slope is slightly negative and it should be shaded under the line since y is less than the line...so it is the second graph.
Answer:
60° is the value of y....
33cm
Because add all of them then subtract then do the parenthasees and you get 33
"a" and integer is a whole number not a fraction or a decimal
Answer:
x = 1.2
y = 6.6
Step-by-step explanation:
1) y= -2x+9
2) 8x-3=y
Substitute y in equation 1 using y in equation 2.
8x - 3 = -2x + 9
+ 3 on both sides
8x = -2x + 12
+ 2x on both sides
10x = 12
x = 1.2
To find y, plug in x
8x - 3 = y
9.6 - 3 = y
6.6 = y
Hope this helps :)
