Answer:
13
Step-by-step explanation:
Given data
flat amount =$10
let the number of dogs walked be x
and let the money earned be y
y= 10+5x
for y= 75
let us find x
75= 10+5x
75-10= 5x
65= 5x
divide both sides by 5
x= 65/5
x=13
Hence the number of dogs is 13
a) If the state covers 20% of the cost per month, that means the student has to pay 80%. So the cost per month for the student is:
2460 * 80/100 = 246 * 8 = 1968 kroner
b) The cost for 9 months would be:
1968 * 9 = 17712 kroner
Yes bc it all goes up by the same numbers
Answer:
y=x-8
Step-by-step explanation:
No integer in front of the x means there is no slope, and a negative "b" means the y-intercept is negative.
y=mx+b
Answer:
f(-3) = -4
Step-by-step explanation:
f(x) = -2x² - 3x + 5
f(-3) = -2(-3)² - 3(-3) + 5
f(-3) = -2(9) + 9 + 5
f(-3) = -18 + 9 + 5
f(-3) = -9 + 5
f(-3) = -4
