[tex]Difference = \frac{13}{40}[/tex]

Step-by-step explanation:

Given

[tex]Thursday = \frac{3}{8}\ mile[/tex]

[tex]Tuesday = \frac{7}{10}\ mile[/tex]

Required

How much farther is she on Tuesday

To do this, we simply calculate the difference between distance covered on both days.

[tex]Difference = Tuesday-Thursday[/tex]

[tex]Difference = \frac{7}{10} - \frac{3}{8}[/tex]

Take LCM

[tex]Difference = \frac{28- 15}{40}[/tex]

[tex]Difference = \frac{13}{40}[/tex]

Hence, she ran 13/40 mile farther on Tuesday

Given,

The expression

"2 times the sum of −3 and m"

We know algebraic expression is the expression which consist of variables and constants with the algebraic operation.

Here,

2 times the sum of -3 and m

Step-by-step explanation:

The answer is C: (-3,-1)

To test if points satisfy an equation, all you need to do is test the numbers in both of the equations it provides you

Here is proof the answer is C :

y > x - 2

(lets plug in point C)

-1 > -3 - 2

solve

-1 > -5 ?

Yes this statement is true- onto the next inequalitity!

y > 2x + 2

-1 > 2(-3) + 2

solve

-1 > -6 + 2

-1 > -4 ?

Know we know answer c (-3,-1) is the right answer!

The point (x,y) satisfies the given system of inequalities is C. (-3,-1).

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality.

Given that The graph below represents the following system of inequalities.

y> - 2

y > 21 + 2

So, y > x - 2

Lets plug in point C;

-1 > -3 - 2

solve;

-1 > -5 ?

Yes this statement is true- onto the next inequalitity.

y > 2x + 2

-1 > 2(-3) + 2

=====================================================

Explanation:

When two letters are placed together without any space between them, this implies multiplication.

gf = g times f

So we'll be multiplying the functions g and f.

There are two ways to approach this problem.

----------------------------------------------

Method 1

First we need to find f(4) and g(4)

f(x) = 2x+3

f(4) = 2*4+3

f(4) = 8+3

f(4) = 11

g(x) = 2x^2-1

g(4) = 2(4)^2-1

g(4) = 2(16)-1

g(4) = 32-1

g(4) = 31

Now we multiply the results

gf(4) = g(4)*f(4)

gf(4) = 11*31

gf(4) = 341

----------------------------------------------

Method 2

We'll multiply g(x) with f(x) like so

gf(x) = g(x)*f(x)

gf(x) = (2x^2-1)*(2x+3)

gf(x) = 2x^2*(2x+3) - 1(2x+3) .... distribute

gf(x) = 4x^3+6x^2-2x-3 .... distribute again

Now plug in x = 4

gf(x) = 4x^3+6x^2-2x-3

gf(4) = 4(4)^3+6(4)^2-2(4)-3

gf(4) = 4(64)+6(16)-2(4)-3

gf(4) = 256+96-8-3

gf(4) = 341

We get the same result. Method 1 may be the better method, but it will depend on your preference.

Answer:

✔️The correct system of linear equations:

2x + 3y = 34

3x + 2y = 36

Cost of each roast beef sandwich: $8

Cost of each turkey sandwich: $6

Step-by-step explanation:

Cost of each roast beef sandwich = x

Cost of each turkey sandwich = y

First platter consists of:

2 roast beef sandwiches, which costs 2 × x = 2x, and,

3 turkey sandwiches, which costs 3 × y = 3y.

Total cost of first platter is $34.

Thus, an equation that represents this scenario would be:

2x + 3y = 34.

The other platter consists of:

3 roast beef sandwiches, which costs 3 × x = 3x, and,

2 turkey sandwiches, which costs 2 × y = 2y.

Total cost is $36.

Thus, an equation that represents this scenario would be:

3x + 2y = 36.

The correct system of linear equations would be:

2x + 3y = 34

3x + 2y = 36

Find the value of x and y by solving simultaneously.

Thus:

2x + 3y = 34 ----› Eqn. 1 × 2

3x + 2y = 36 ----› Eqn. 2 × 3

4x + 6y = 68

9x + 6y = 108

Subtract

-5x = - 40

Divide both sides by -5

x = 8

Cost of each roast beef sandwich = x = $8

Substitute x = 8 into eqn. 1.

2x + 3y = 34 ----› Eqn.

2(8) + 3y = 34

16 + 3y = 34

3y = 34 - 16

3y = 18

Divide both sides by 3

y = 6

Cost of each turkey sandwich = y = $6

Answer:

  (d)

Step-by-step explanation:

You want the inverse function of the given one-to-one function.

A function given as ordered pairs is one-to-one if no x-values are repeated and no y-values are repeated.

As the directions tell you, the inverse function is found by changing the order of the values in each ordered pair.

  function  ⇒  inverse function

Answer:

Step-by-step explanation:

3+5=8. 360÷8=45. 45×3=135

If the ratio of cars to trucks in the parking lot is 3:5. If there are 360 vehicles in the parking lot, then there are 225 trucks

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

The ratio of cars to trucks in the parking lot is 3:5.

there are 360 vehicles in the parking lot

(360-x)/x=3/5

Cross Multiplication

5(360-x)=3x

1800-5x=3x

1800=8x

x=225

So there are 225  trucks.
