Answer:

the number of miles is 14,722

Step-by-step explanation:

The computation of the number of miles drive last year is shown below:

= Total cost ÷ cost per mile

= $1,560 + $3,740 ÷ $0.36 per mile

= $5,300 ÷ $0.36 per mile

= 14,722 miles

Hence, the number of miles is 14,722

Answer:

m<BXY = 36degrees

Step-by-step explanation:

If XY bisects ∠AXB, then;

<AXY + <BXY = <AXB

Given

m∠AXY = (3x^2 - 12)°

m∠AXB = -18x°

Required

Find m∠BXY.

From the formula above;

Find m∠BXY = <AXB - <AXY

m<BXY = -18x - (3x^2-12)

m<BXY = -18x - 3x^2 + 12

m<BXY =  -3x^2 -18x + 12

Also <AXY = m<BXY

3x^2 - 12 =   -3x^2 -18x + 12

6x^2 + 18x -24 = 0

x^2+3x-4 = 0

Factorize

x = -3±√9+16/2

x = -3±5/2

x = -3+5/2 and -3-5/2

x = 2/2 and -8/2

x = 1 and -4

Substitute x = 1 into m<BXY

m<BXY =  -3x^2 -18x + 12

m<BXY =  -3(1)^2 -18(1) + 12

m<BXY =  -3 -18+ 12

m<BXY =  -9

when x= -4

m<BXY =  -3(-4)^2 -18(-4) + 12

m<BXY =  -3(16) +72+ 12

m<BXY =  -48+84

m<BXY = 36degrees

Answer:

1) 5*x + 6 = 2 + 3*x

5*x - 3*x = 2 - 6

(5 - 3)*x = -4

2*x = - 4

x = -4/2 = -2

x = -2

We have only one solution.

2) 2*(6 - 2*y) = -1*(4*y - 9)

12 - 4*y = -4*y + 9

12 - 9 = -4*y + 4*y = 0

3 = 0

This is absurd, so this equation has no solution.

3) 2*z - 6 = 2*(z + 2) - 10

2*z - 6 = 2*z + 4 - 10

2*z - 6 = 2*z - 6

Here we have the exact same thing on both sides of the equation, then we have infinite solutions, this happens because z can take any value, and the equation will be true always.

4) We want to have no solutions, so we need to end with something like:

1 = 6

so, we start with:

5*x + 1 = 5*x + A

We want to find the value of A.

First, we can subtract 5*x in both sides, so we get:

1 = A

Now we just need to take A different than 1, for example, if A  = 2, then:

1 = 2

In this case the equation has no solutions, then we have:

5*x + 1 = 5*x + 2

5) We want to have one solution:

3*x - 3 = A*x + 11

We want to end with something like x = k

Let's solve the equation for x:

3*x - 3 = A*x + 11

3*x - A*x = 11 + 3

(3 - A)*x = 14

if we take A = 2, then:

(3 - 2)*x = 14

x = 14

So this equation has only one solution, the equation is:

3*x - 3 = 2*x + 11

6) We want to have infinitely many solutions, then we need to have the same thing on both sides, then we need to have an equation like:

8*x - 7 = 8*x - 7

Answer:

14.72 or [tex]8.5\sqrt{3} \\[/tex]

Step-by-step explanation:

Divide 17 by 2 to get the length of the shorter leg and if you do that you get 8.5 and to get the length of the longer leg just multiply 8.5 by [tex]\sqrt{3}[/tex]

The value of "a" for a narrow graph will be equal to 7.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

GIven functions are:-

f(x)   =   ax²

f(x)   =   7

At the value of a=7 the graph of function f(x) =  7x² opens upward and is narrower than the graph of f(x) = x².

Hence the value of "a" for a narrow graph will be equal to 7.

Answer:

20 years

Step-by-step explanation:

We start by writing an exponential equation;

FV = PV( 1 + r)^t

FV is the future value = 1,000,000

PV is present value = 372,000

r is rate = 5% = 5/100 = 0.05

t is time which we are looking for

1,000,000 = 372,000(1 + 0.05)^t

1.05^t = 1,000,000/372,000

1.05^t = 2.688

t ln 1.05 = ln 2.688

t = ln 2.688/ln 1.05

t = 20 years

Answer:

Both A and B are true identities

Step-by-step explanation:

A. N ( n − 2 ) ( n + 2 ) = n 3 − 4 n

We need to show that (left-hand-side)L.H.S = R.H.S (right-hand-side)

So,

 n ( n − 2 ) ( n + 2 ) = n(n² - 2²)     (difference of two squares)

                               = n³ - 2²n       (expanding the brackets)

                               = n³ - 4n         (simplifying)

So,                L.H.S  = R.H.S

B. ( x + 1 )² − 2x + y² = x² + y² + 1

We need to show that (left-hand-side)L.H.S = R.H.S (right-hand-side)

So,

( x + 1 )² − 2x + y² = x² + 2x + 1 - 2x + y²   (expanding the brackets)

                             = x² + 2x - 2x + 1  + y²   (collecting like terms)

                             = x² + 1 + y²        

                             = x² + y² + 1                    (re-arranging)

So,              L.H.S  = R.H.S

So, both A and B are true identities since we have been able to show that L.H.S  = R.H.S in both situations.

Answer:

x = 13

Step-by-step explanation:

The angle adjacent to (2x + 19) on line l is corresponding to (9x + 18) and are congruent.

Then (2x + 19) and (9x + 18) are adjacent angles and supplementary, that is

2x + 19 + 9x + 18 = 180

11x + 37 = 180 ( subtract 37 from both sides )

11x = 143 ( divide both sides by 11 )

x = 13

Answer:

x = 13

Step-by-step explanation:

(9x+18)+ (2x+19) = 180 because they are same side exterior angles

reduce:

11x + 37 = 180

11x = 143

x = 13

check:

9(13) + 18 + 2(13) + 19 = 180

117 + 18 + 26 + 19 = 180

180 = 180
