Answer:
10 slices of pizza were sold
Step-by-step explanation:
Let x be the no. of pizza slices sold
Let y be the no. of hot dogs
25 total items were sold
So, x+y=25 ---1
A pizza cost $2 and a hot dog costs $1
Cost of x slices of pizza = 2x
Cost of y hot dogs = y
They made total $35
2x+y=35 ---2
Substitute the value of y from 1 in 2
2x+25-x=35
x=35-25
x=10
Hence 10 slices of pizza were sold
Isn't it d because he has 4points scored already and a additional 3 right?
Answer:
a) For a constant increment in x-variable, there is a constant increment in y-variable, for example, for x = 0 to x = 0.5 (increment = 0.5) y-variable goes from 60 to 62 (increment = 2); the same is valid for any couple of (x,y) values. This behaviour is characteristic of linear equations.
b) slope:
m = (increment in y-variable)/(increment in x-variable) = 2/0.5 = 4
y-intercept:
y1 = m*x1 + h
60 = 4*0 + h
60 = h
equation: y = 4x + 60
where y represents scores and x represents hours spent studying
c) The slope indicates that you need to study 1 hour to increase your score in 4 points
The y-intercept indicates that you will get at least a score of 60, even though you hadn't studied
Answer:
905
Step-by-step explanation:
arithmetic sequence are in form
a(n)=a(0)+d(n-1)
a(0)=25
common difference: d=35-25=10
a(n)=25+10(n-1)
a(89)=25+10(88)=905
