Find s:

Let the student tickerts and general tickets be x and y respectively

From (1) put in (2)

And

Using Cramer's rule it is found that Dx = -34.

In Cramer's rule, we have three matrices.

In this problem, the system is:

[tex]6x - 5y = -4[/tex]

[tex]-7x + 3y = -1[/tex]

Matrix x is given by:

[tex]x = \left[\begin{array}{ccc}6&-4\\-7&-1\\\end{array}\right][/tex]

It's determinant is given by:

[tex]Dx = 6(-1) -(-4)(-7) = -6 - 28 = -34[/tex]

Thus, Dx = -34.

Answer:

18°

Step-by-step explanation:

1. ∠A and ∠B are complementary angles, so they add up to 90°.

2. To find the measure of ∠A, we first have to solve for x.

3. (Solving)

Step 1: Simplify both sides of the equation.

Step 2: Subtract 13 from both sides.

Step 3: Divide both sides by 7.

4. Now that we know x = 11, let's plug that value into (2x - 4) to find the measure of Angle A.

Therefore, the measure of ∠A = 18°.

Answer:

m<A = 18

Step-by-step explanation:

Since <A and <B are complementary angles, that just means those 2 angles combined equal 90:

<A + <B = 90

2x - 4 + 5x + 17 = 90

7x + 13 = 90

7x = 90 - 13

7x = 77

x = 77/7

x = 11

m<A:

Answer:

[tex]\sf f^{-1}(x) = \dfrac{x}{2}+4[/tex]

Step-by-step explanation:

A function is given to us and we need to find the inverse of the function in slope intercept form . The given function is ,

[tex]\sf\implies f(x) = 2x - 8 [/tex]

Let us assume that y = f(x) , so that ,

[tex]\sf\implies y = 2x - 8 [/tex]

Now interchange the positions of x and y , we have ,

[tex]\sf \implies x = 2y - 8[/tex]

Solve for y in terms of x ,

[tex]\sf \implies 2y = x + 8 \\\\\sf\implies y =\dfrac{x}{2}+4 [/tex]

This is the inverse of the function in slope intercept form. Now we can replace this y with f-¹(x) , as ,

[tex]\sf \implies \boxed{\pink{\frak{f^{-1}(x) = \dfrac{x}{2}+4}}}[/tex]

Interpreting the situation, we have that:

a) The system of equations is:

[tex]y = 2x - 7[/tex]

[tex]y = 6 + x[/tex]

b) Solving the above system, it is found that Jacob scored 13 and Paul scored 19.

Item a:

In our system, we have that:

Jacob said that Paul's score would be twice his own score if he earned 7 more points, which means that:

[tex]y + 7 = 2x[/tex]

[tex]y = 2x - 7[/tex]

Paul responded to Jacob by telling him his score was only 6 points higher then Jacob's, which means that:

[tex]y = 6 + x[/tex]

Item b:

Equaling both equations:

[tex]2x - 7 = 6 + x[/tex]

[tex]x = 13[/tex]

[tex]y = 6 + x = 6 + 13 = 19[/tex]

Jacob scored 13 and Paul scored 19.

Answer:

136.8

Step-by-step explanation:

As per DMAS rule, we can divide first or multiply first. I would choose divide first. Then:

4.56 x 3.6/0.12

= 4.56 x 30.

Since I divided first, the next step is to multiply.

4.56 x 30

= 136.8

Since there is no addition or subtraction happening next, the process ends here and the answer is 136.8.

Please give me brainliest if this was helpful.

The expression value  [tex]4.56 \times \frac{ 3.6}{0.12}[/tex] in standard form is 136.8=1.368×10².

To evaluate the expression [tex]4.56 \times \frac{ 3.6}{0.12}.[/tex]

Find the multiplication of the numerator with 4.56 and then divide it by 0.12.

Perform the multiplication first:

4.56×3.6 = 16.416

Now we divide the result by 0.12:

[tex]\frac{16.416}{0.12} = 136.8[/tex]

To express the answer in standard form, we rewrite it as a number multiplied by a power of 10.

In this case, we move the decimal point two places to the right to obtain a whole number:

136.8=1.368×10²

Therefore, the answer to the expression  [tex]4.56 \times \frac{ 3.6}{0.12}[/tex] in standard form is 136.8=1.368×10²

Answer:

m∠1 = 75° m∠2 =45° m∠3 = 60°

Step-by-step explanation:

m∠1 = 180 - { (180 - 135) + (180 - 120) }

m∠1 = 180 - { 45 + 60 }

m∠1 = 75°

The angle between 1 and 3, lets call it x,  is vertically opposite to ∠2, so we must find it first to be able to get ∠2

Since a ║b

Therefore ∠x and ∠135 are co-interior angles

Therefore ∠x = 180-135

m∠x = 180 - 135

m∠x = 45°

∠2 = ∠x (Vertically opposite angles)

∠2 = 45°

Between ∠2 and ∠3 there is an angle, let's call it z.

∠z = ∠1 (Vertically opposite angles)

∠z = 75°

Since the sum of angles 2, z and 3 = 180° (Straight angle)

Therefore m∠3 = 180 - (∠2 + ∠z)

m∠3 = 180 - (45 + 75)

m∠3 = 60°

Or in a different way

∠2 + ∠z + ∠3 = 180

45 + 75 + ∠3 = 180

120 + ∠3 = 180

∠3 = 180 - 120

∠3 = 60°
