Answer:
(C) 2
Step-by-step explanation:
Given equations 2a + 7b+2c=16 and 2a + 3b +2c= 8, you want to know the value of b.
<h3>Solution</h3>
The coefficients of 'a' and 'c' are the same in the two equations, so we can eliminate those variables by subtracting one equation from the other. We can keep the resulting coefficient of 'b' positive if we subtract the second equation from the first.
(2a +7b +2c) -(2a +3b +2c) = (16) -(8)
4b = 8 . . . . . . . simplify
b = 2 . . . . . . . divide by 4
Admission cost to the fiar = $12.99.
Each ride cost = $1.75.
Let us assume number of rides = x.
a) Addimission charges + each ride cost *x <= Total money have.
We are given total money have = $35.
We can setup an inequality now
12.99 + 1.75*x <=35.
12.99 +1.75x <=35 is the required inequality.
b) Let us solve this inequality for x.
12.99 +1.75x <=35
Subtracting both sides by 12.99, we get
12.99-12.99 +1.75x <=35-12.99
1.75x <= 22.01.
Dviding both sides by 1.75
1.75x/1.75 <= 22.01/1.75
x< = 12.5771..
We got value of x less than or equal to 12.5771.... Number of rides could be a whole number.
Therefore, 12 are the maximum number of rides you can enjoy at the hot summer fair.
Step-by-step explanation:
b
The inverse is basically switc x and y
so if (a,b) is a point on f(x), then (b,a) is on th inverse
(7,2) is on it so on inverse, (2,7) has to be on it
C
