Answer 1
Answer: so F(m) because F dollars for every mph over the speed limit
so 40 dollar speeding fine so +40 
10 dollars for every mile over and m=miles over so put them all toghether and get
F(m)=10m+40


1.
so if you were going 78 mph
to find the mph over you would do 78-70=8mph over so put in 8 for m and get
F(8)=10(8)+40=80+40=$120 fine for going at 78 mph

Find the non-extraneous solutions of the square root of the quantity x plus 9 minus 5 equals quantity x plus 4

Answers

Answer:

x=8 and x=9

Step-by-step explanation:

The given equation is:

√(x+9)-5=x+4

On solving this equation, we get

√(x+9)=x+9

Squaring on both sides, we get

x+9=x^2+81+18x

x^2+18x-x-9+81=0

x^2+17x+72=0

x^2+8x+9x+72=0

(x+8)(x+9)=0

Thus, the solution of the above equations are x= 8 and x=9.

I"m guessing you mean
√(x+9) -5=x+4
add 5 to both sides
√(x+9)=x+9
square both sides
x+9=x²+18x+81
minus x+9 both sides
0=x²+17x+72

x=-9

test each

√(-8+9) -5=-8+4
√(1) -5=-4
1-5=-4
-4=-4
true

√(-9+9) -5=-9+4
√(0) -5=-5
-5=-5
true


the solutions are x=-9 and -8

The coins in the store s cash register total $12.50. The cash register contains only nickels, dimes, and quarters. There are twice as many dimes as nickels. There are also twice as many quarters as dimes. How many quarters are in the cash register?

Answers

nickels is 0,05 of dolar - n
dimes is 0,1 o dolar -d
quarters is 0,25 of dolar -q
dimes =2nickels
d=2n
quarters=2dimes
q=2d=4n
12,5=n(0,05)+2n(0,1)+4n(0,25)
12,5=0,05n+0,2n+n
12,5=1,25n
n=10
q=4n=40
There are 40 quarters

WRITE A COMPOUND INEQUALITY FOR EACH GRAPH PLEASEEE HELP DUE IN !) MINUTES!!!!!

Answers

The compound inequalities for each number line is 18: −1≤x≤4 19: −3<x≤2 20: x<0 or (1≤x≤3) 21: (−4<x≤−6) or (−3<x≤0) 22: (3≤x<1) or (6<x<7) 23: (−3≤x≤−4) or (0<x<2).

let's break down the compound inequalities for each situation step by step:

18:

−1≤x≤4 (closed on both ends)

The notation ≤ means "less than or equal to," so

−1≤x indicates that

x can be equal to or greater than -1.

Likewise,

x≤4 means that

x can be equal to or less than 4.

Combining both inequalities, we have

−1≤x≤4, indicating that

x can take any value between -1 and 4, including -1 and 4.

19:

−3<x≤2 (open on the left end, closed on the right end)

The notation < means "less than," so −3<x indicates that

x must be greater than -3 but not equal to -3.

x≤2 means that

x can be equal to or less than 2.

Combining both inequalities, we have

−3<x≤2, indicating that x can take any value greater than -3 and up to and including 2. It's open at -3 but closed at 2.

20: x<0 or (1≤x≤3) (open on the left end, closed on the right end, with a gap between 0 and 1)

x<0 indicates that x must be less than 0.

(1≤x≤3) indicates that x can be equal to or greater than 1 and equal to or less than 3.

Combining these two inequalities with "or," we have

x<0 or

1≤x≤3, indicating that x can be less than 0 or take any value between 1 and 3, including 1 and 3.

21:

(−4<x≤−6) or

(−3<x≤0) (open on both ends with a gap between -3 and -4)

(−4<x≤−6) indicates that x must be greater than -4 but not equal to -4, and it can be equal to or less than -6.

(−3<x≤0) indicates that x must be greater than -3 but not equal to -3, and it can be equal to or less than 0.

Combining these two inequalities with "or," we have

(−4<x≤−6) or

(−3<x≤0), indicating that

x can take any value greater than -4 and up to -6, or greater than -3 and up to 0.

22:

(3≤x<1) or

(6<x<7) (closed on the left end, open on the right end, with a gap between 1 and 6)

(3≤x<1) indicates that x can be equal to or greater than 3 and less than 1.

(6<x<7) indicates that x must be greater than 6 and less than 7.

Combining these two inequalities with "or," we have

(3≤x<1) or (6<x<7), indicating that x can take any value equal to or greater than 3 and less than 1, or greater than 6 and less than 7.

23:

(−3≤x≤−4) or

(0<x<2) (closed on the left end, open on the right end, with a gap between -4 and 0)

(−3≤x≤−4) indicates that x can be equal to or greater than -3 and equal to or less than -4.

(0<x<2) indicates that

x must be greater than 0 but less than 2.

Combining these two inequalities with "or," we have

(−3≤x≤−4) or

(0<x<2), indicating that x can take any value equal to or greater than -3 and equal to or less than -4, or greater than 0 and less than 2.

These compound inequalities describe the ranges of values for x in each given situation on the number line.
