Answer:

y = -3x - 9

Step-by-step explanation:

Parallel lines have same slope.

y = mx + b

m -> slope & b ->y-intercept

y = -3x - 2

So, slope of the required line = -3

(-4 , 3)

y -  y1 = m(x - x1)

y - 3 = -3(x - [-4])

y - 3 = -3(x + 4)

y - 3 = x*(-3) + 4*(-3)

y - 3 = -3x - 12

     y = -3x -12 + 3

     y = -3x - 9

Answer:

63.17

Step-by-step explanation:

add all the numbers together which gives you 379

then 379 by how many numbers there are.

there are 6 numbers so divide 379 by 6 which equals 63.16666667

and if you round to the nearest hundredth it gives you 63.17

Answer:

64in cubes

Because if the vase is half full, half of 8 is 4. To find the volume of a cube is l x W x H. So 4 x 4 x 4= 64.

Answer:

17/100

Step-by-step explanation:

The unknown quantity in the given expression is 17/100

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is an expression, 8/10 + x = 97/100, we need to find x,

So,

8/10 + x = 97/100

Subtract 8/10 from both the sides,

8/10 + x -8/10 = 97/100-8/10

x = 97/100-8/10

Multiply by 100 both the sides,

100 x = 100(97/100-8/10)

100x = 97-80

100x = 17

Divide the equation by 100

x = 17/100

Hence, the unknown quantity in the given expression is 17/100

Answer:

the money after 11 years is £15,735.12

Step-by-step explanation:

The computation of the amount after 11 years is given below:

Future value = Present value × (1 + rate of interest)^number of years

= £9,200 × (1 + 0.05)^11

= £9,200 × 1.05^11

= £9,200 × 1.710339358

= £15,735.12

Hence, the money after 11 years is £15,735.12

17

Answer:

17

Step-by-step explanation:

You add what's inside the parenthesis, then rewrite the equation once more, (3)(9)-12+2, then you gotta multiply 3*9 which is 27. Rewrite the equation again, 27-12+2, then you must subtract 27 from 12 which is now 15. So now we're left with 2, 15+2 is 17. If it makes it any easier, think of this equation as losing friends and gaining friends, and now you're left with 17 now.

Answer:

(a+b) ²≥4ab explanation below↓↓↓↓

Step-by-step explanation:

We know that

(a-b) ²≥0

a²-2ab+b²≥0

Move -2ab to the other side

a²+b²≥2ab

Add 2ab to both sides

a²+2ab+b²≥4ab

(a+b) ²=a²+2ab+b² therefore :

(a+b) ²≥4ab

Answer:

Because [tex]x = y[/tex], then the solution is unique.

Step-by-step explanation:

Given

[tex]Ax = b[/tex]

[tex]Ax=0[/tex]

See comment for complete question

Let there be two solutions x and y.

Such that:

[tex]Ax = b[/tex] and [tex]Ay = b[/tex]

Since:

[tex]Ax = Ay = b[/tex]

Then:

[tex]Ax - Ay = b - b[/tex]

[tex]Ax - Ay = 0[/tex]

This implies that:

[tex]Ax - Ay = A(x-y) = 0[/tex]

The only trivial solution is:

[tex]Ax - Ay = A(x-y) = 0[/tex]

Such that:

[tex]x -y = 0[/tex]

Then

[tex]x = y[/tex]

Because [tex]x = y[/tex], then the solution is unique.
