Answer:
y = 3x - 19
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Define variables
Slope <em>m</em> = 3
Random point (5, -4)
Step 2: Plug in known variables
y = 3x + b
Step 3: Find <em>b</em>
-4 = 3(5) + b
-4 = 15 + b
b = -19
Step 4: Write linear equation
y = 3x - 19
Answer:
Step-by-step explanation:
12.9 + 10.2x = 35.1
10.2x = 35.1 - 12.9
10.2x = 22.2
x = 22.2/10.2
x= 222/102 = 111/51
I don't see the expression below.
Since the 40% discount applies to the number of cookies sold above 2 dozen, or 24, then if the number of cookies is c, then c - 24 is the number of cookies above 2 dozen. Answer is B.
Answer:
25 mins
Step-by-step explanation:
Harpeet worked -- x mins
Aiysha worked -- 2x mins
If Aiysha worked 50 mins, Harpeet worked:
2x = 50
x = 25 mins
Thenks and mark me brainliest :))
