Can someone substitute this to find x and y​

Answer:

[tex]{ \sf{ {(2x - 3)}^{4} }} \\ = { \sf{ {(2x - 3)}^{2} . {(2x - 3)}^{2} }} \\ = { \sf{(4 {x}^{2} - 12x + 9)(4 {x}^{2} - 12x + 9) }} \\ = { \sf{ {16x}^{4} - 48 {x}^{3} + 36 {x}^{2} - 48 {x}^{3} + 144 {x}^{2} - 108x + 48 {x}^{2} - 108x + 81 }} \\ { \sf{ = {16x}^{4} - 96 {x}^{3} + 228 {x}^{2} - 216x + 81 }}[/tex]

Answer:

A) Commutative

Step-by-step explanation:

The Associative has to do with re-grouping numbers. There are only two numbers so this does not apply here. Commutative is where you change the order; that's what the equation is demonstrating.

Answer:

The Commutative Property.

Step-by-step explanation:

The commutative property says that when multiplying, you can change the order without changing the answer.

Step-by-step explanation:

Infinitely many solutions are there....

Different type of spaghetti dinners is 8

What is combination ?

"The number of possible arrangements in a collection of items where the order does not matter."

For 4 different shaped of noodles = ⁴c₁

                                             ⁴c₁ = 4        

For two kinds of cheese = ²c₁

                                         ²c₁ = 2

Now , multiplying these  4×2 = 8

Hence, 8 type of spaghetti dinners

Step-by-step explanation:

There are 60 students that prefer soccer

The first step is to determine the percentage of students that prefer soccer The percentage of students that prefer soccer = 100 - (53% + 26% + 15% ) = 6%

6% of the students surveyed prefer soccer

The second step is to determine the number of students that prefer soccer

Number of students that prefer soccer = (percentage of students that prefer soccer / 100) x total number of students surveyed

[tex]\frac{6}{100}[/tex] × 1000 = 60 students

Answer:

32π in

= 100.48 in.

Step-by-step explanation:

From Area:

radius, r = √(A/π)

= √(256 π in²/π)

= 16 in

where π = 3.14

》 Circumference = 2π(r)

= 2π(16)

= 32π in.

= 100.48 in

Answer:

Yes

Step-by-step explanation:

Both arguments are squared so the equation are in the form of a circle.

A lotus is a point that is equidistant from some fixed point of a conic section. This is a circle so the fixed point is called a center of the circle.

The center of the circle is equidistant from any point on the circumference of the circle. In order for a point to be on the circle, it must satisfy the circle equation.

[tex] {x}^{2} + {y}^{2} = {r}^{2} [/tex]

Let plug in what we know

[tex]3 {}^{2} + ( - 4) {}^{2} = {5}^{2} [/tex]

[tex]9 + 16 = {5}^{2} [/tex]

So 3,-4 is on the locus of the circle.

Answer:

Since both have equal length

9x - 2 = 6x + 13

9x - 6x = 13 + 2

3x = 15

x = 15/3

x = 5

Length of BC = 6(5) + 13 = 43 cm

Step-by-step explanation:

Solution,

AB=9x-2

BC=6x+13

Now,

AC=AB+BC

=9x-2+6x+13

=15x+11

Answer:

Below.

Step-by-step explanation:

I cant draw you a picture but it will be one right triangle inside the other where the vertical tower will be one leg common to 2 triangles and the base of the 2 triangles will be x and x+10 metres.

Tan 30 = h/ (x + 10)

tan 45 = h/x        where h is the height of the tower.

From the second equation  x = h / tan45

Substituting in the first equation;

tan30 = h / (h/tan45 + 10

Tan 30 = 1/ √3 and tan 45 = 1 so

1/ 1.732 = h/ (h + 10)

0.5774 = h/(h + 10)

h = 0.5774h + 57.74

0.4226 h = 57.74

h = 136.6 m to nearest tenth.

Step-by-step explanation:

First;

x to third power=x³

y to 4th power=y⁴

According to condition:
