Answer:
y = 7/5x + 18/5
Step-by-step explanation:
so we have y = mx + b
f(1) = 5
f(-4) = -2
so let's find b
so like if you do (5 - (-2))/(1 - (-4)) you get (5 + 2)/(1 + 4) = 7/5
y = 7/5x + b
so now we can plug in a value like f(1) = 5
5 = (7/5)1 + b
b = 18/5
Answer: 23 minutes
Step-by-step explanation:
4x + 8 = 100
100 is 8 more than 4 times of minutes than last week.
X = minuted she studied last week.
Find x
4x = 100 - 8
4x = 92
x = 92/4
x = 23 minutes
Its 20 the sides are equal
