Answer:

126  miles

Step-by-step explanation:

1/4 inches = 9 miles

Divide 3.5 by 1/4 or 0.25

3.5 ÷ 0.25 = 14

Multiply 14 by 9

14 x 9 = 126

Answer:

vertex = (- 1, 1 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = x² + 2x + 2 ← is in standard form

with a = 1 and b = 2 , then

x = - [tex]\frac{2}{2}[/tex] = - 1

substitute x = - 1 into the equation for y- coordinate of vertex

y = (- 1)² + 2(- 1) + 2 = 1 - 2 + 2 = 1

vertex = (- 1, 1 )

Answer:

n= - 3/5

Step-by-step explanation:

1- Substitute f ( n ) = 0 remove the parentheses

2- Calculate

3- Move the variable to the left

4- Divide both sides

Answer:

n = 135/7

Step-by-step explanation:

2 x long side + short side = 75

substitute measures                 ⇒ 2(1.5n + 3) + (0.5n + 1.5) = 75

multiply out brackets               ⇒ 3n + 6 + 0.5n + 1.5 = 75

gather like terms                      ⇒ 3n + 0.5 n + 6 + 1.5 = 75

combine like terms                  ⇒ 3.5n + 7.5 = 75

subtract 7.5 from both sides   ⇒ 3.5n = 67.5

divide both sides by 3.5          ⇒ n = 135/7

No, it isn't.

Answer:

Step-by-step explanation:

So what you need to do is take the two points (1, -5) and (3, -1) and subtract them. You take y of the second group and subtract y of the first group.

-1 - (-5) = 4

Now you do the first numbers in each group with the second set being the number you subtract from.

3 - 1 = 2

Now you do [tex]\frac{Rise}{Run}[/tex]. Rise = 4 Run = 2

[tex]\frac{4}{2}[/tex] = 2

Now the second part is saying y = 3x + c with your first set of numbers being x and y.

x = 1

y = -5

-5 = 3(1) + c

-5 = 3 + c

Subtract 3 from -5

-8 = c

The final answer is:

y = 3x - 8

Step-by-step explanation:

Simply Equation 1

R. H. S

6x^2 -x +3-2x^2-8

==> 6x^2-2x^2 -x +3-8

==> 4x^2-x-5 .....(1)

Simply equation 2

L. H. S

4x^2+2x-5-3x

==> 4x^2 +2x-3x-5

==> 4x^2-x-5 ....(2)

Since here, RHS = LHS

both eqn (1) = eqn(2)

hence they are equal.

Answer:

yes they are equal

Step-by-step explanation:

for the equation [tex]4x^{2} +2x-5-3x[/tex] you're going to collect like terms

2x-3x=5x

so your final equation is [tex]4x^{2} -x-5[/tex]

for the equation [tex]6x^{2} -x+3-2x^{2} -8[/tex] you're going to collect like terms

[tex]6x^{2} -2x^{2} =4x^{2}[/tex]

then you're going to calculate the difference

3x-8=-5

so your final equation is [tex]4x^{2} -x-5[/tex]

x+y < 500

The points satisfying the 2nd inequality is a triangle bordered by the x and y axes and a downward sloping line connecting points (0,500) and (500,0)

the 1st inequality is half a plane, above the line x=2y or a  line through the origin, with slope 1/2

the two overlap in a triangle bordered by the y axis, the line x+y=500 and the line x=2y

It's a triangle with vertices (333 1/3, 166 2/3) (0,500) and the origin (0,0)

y + 4x ≤ $500

Answer:

m = 36

n = 3

Step-by-step explanation:

y varies inversely with x can be written as y ≅ 1/x.  As x goes up, y will go down.  We need a factor, N, to account for how much change occurs with each step.  There needs to be a factor involved, F, to account for how much change occurs with each step.  

Calculate the factor by using one of the known points.  I'll use (8,9):

y = F/x

9 = F/8

F = 72

The relation becomes y = 72/x.  Check this on the other given point, (12,6):

y = 72/x

6 = 72/12  ?   YES

Now use y = 72/x to find the two missing points, (m,2) and (24,n):

(m,2) 2 = 72/m,     m = 36

(24,n)  n = 72/24;   n = 3

Answer:

System of equation : 14x+23y = 213 and y = x-2

The cost of regular tickets is $7 and the cost of tickets with donation is $5.

Step-by-step explanation:

Let regular ticket's cost be x and tickets with donation's cost be y.

14x+23y = 213

y = x-2

Now,

14x+23y = 213

or, 14x+23(x-2) = 213

or, 14x + 23x - 46 = 213

or, 37x = 259

so, x = 7

again,

y = x-2

or, y = 7-2

so, y = 5

Answer:

$289,169.84 (to the nearest cent)

Step-by-step explanation:

Compound interest is based on the principal amount and the interest that accumulates on it in every period.

Compound Interest = P (1 + r)^n

where P = principal amount, r = annual interest rate (as a decimal), n = term, in years​

So for this problem:

P = 185000

r = 1.4 ÷ 100 = 0.015

n = 30

Therefore,  

Compound Interest = P (1 + r)^n

                                = 185000 x (1 + 0.015)^30

                                = 185000 x (1.015)^30

                                = 289169.8408...

                                = $289,169.84 (to the nearest cent)
