I'd really appreciate some workings out too :)
Thanks,

Answer:

u=30

x=150

z=150

y=30

Step-by-step explanation:

u=y [ being vertically opposite angle]

x+u=180[ being linear pair]

x+30=180

x=180-30

x=150

z=x[being vertically opposite angle]

z=150

y=u[ being voa]

Answer:

=40°

Step-by-step explanation:

Sorry that's all I know

The value of x so that lines s and t are parallel is 12

The angle are alternate exterior angles.

Therefore, alternate exterior angle theorem states that when two parallel lines are intersected by a transversal, then the exterior angles formed on either side of the transversal are equal.

Hence,

7x - 20 = 4x + 16

7x - 4x= 16 + 20

3x = 36

x = 36 / 3

x = 12

Therefore, the value of x is 12.

The equation that can be solved using the system of equations is 4x^4 + 6x^3 - 11 = 3x^5 - 5x^3 + 2x^2 - 10x + 4

The correct formats of the equations are:

y = 3x^5 - 5x^3 + 2x^2 - 10x + 4

y = 4x^4 + 6x^3 - 11

To determine the equation, we substitute 4x^4 + 6x^3 - 11 for y in the first equation.

So, we have:

4x^4 + 6x^3 - 11 = 3x^5 - 5x^3 + 2x^2 - 10x + 4

Hence, the equation that can be solved using the system of equations is 4x^4 + 6x^3 - 11 = 3x^5 - 5x^3 + 2x^2 - 10x + 4

The money was in the SACCO for a time of 0.78125 years.

Simple interest is defined as the interest obtained over the principal amount on a certain rate.

Given that,

Amount of money deposited or principal amount = 56,800

Rate of interest = 12% = 12/100 = 0.12

Final amount = 62,125

The formula for simple interest is,

A = P(1 + rt), where A is the final amount, P is the principal amount, r is the interest rate and t is the time.

Substituting,

56800 (1 + 0.12t) = 62125

1 + 0.12t = 1.09375

0.12t = 0.09375

t = 0.78125 years

Hence the time that the money kept for is 0.78125 years.

The equation for the (x-4)²2 is  5. x=4± √5. Hence, option D is correct.

Due to the fact that they contain two or more algebraic terms, quadratic equations fall within the category of polynomial equations. It must equal 0 in order to solve a quadratic equation. There can be zero, one, or two (true) solutions to a quadratic equation.

To solve the equation (x - 4)² = 5, we can start by taking the square root of both sides:

√[(x - 4)²] = ±√5

This gives us two possible equations:

x - 4 = √5 or x - 4 = -√5

Now it can add 4 to both sides of each equation:

x = 4 + √5 or x = 4 - √5

So the solutions to the equation (x - 4)² = 5 are x = 4 + √5 and x = 4 - √5.

Thus, option D is correct.

Answer:

Step-by-step explanation:

the recursive rule is

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + d ( d is the common difference )

use the explicit rule to find a₁ and d

a₁ = 48 - 11(1) = 48 - 11 = 37

a₂ = 48 - 11(2) = 48 - 22 = 26

then

d = a₂ - a₁ = 26 - 37 = - 11

recursive rule is then

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 11

a₁ = 37
