Let y = 0 to find the x-intercept(s).
0 = 45 − 4x
*Then subtract 45 from both sides*
-45 = -4x
*Next, DIVIDE both sides by -4*
-45
—— = x
-4
*NEXT, realize that TWO NEGATIVES MAKE A POSITIVE *
45. 4
——— = x {FLIP} x=——-
4. 45.
y-Intercept
Let x = 0 to find the y-intercept(s).
y = 45 −4(0)
NEXT, SIMPLIFY:
y=45
Answer:
12−2
Step-by-step explanation:
Simplify,
(11+3)+(−5)
11+3+−5
Subtract,
11+3+−5
11−2+
Combine like terms,
11−2+
12−2
Since we can't go any further, the solution is,
12−2
Answer:
80%
Step-by-step explanation:
regular price is 100%
so, after the discounted price is 20%
the discount is 80%
