Answer:

As you have written the equations, the solution is (-1.5, 1.5).

Step-by-step explanation:

As written, the system of equations is

\left \{ {{3y=x+6} \atop {y-x=3}} \right.

To solve this, we will use substitution.  First we will isolate y in the second equation:

y-x = 3

Add x to each side:

y-x+x = 3+x

y = 3+x

Now we will substitute this into the first equation

3y = x+6

3(3+x) = x+6

Using the distributive property,

3(3)+3(x) = x+6

9+3x = x+6

Subtract x from each side:

9+3x-x = x+6-x

9+2x = 6

Subtract 9 from each side:

9+2x-9 = 6-9

2x = -3

Divide both sides by 2:

2x/2 = -3/2

x = -1.5

Substitute this into the second equation:

y-(-1.5) = 3

y+1.5 = 3

Subtract 1.5 from each side:

y+1.5-1.5 = 3-1.5

y = 1.5

harkovskaia [24]

Given:

The function is:

h(x)=x^2-3x+5

To find:

The value of h(2x+1).

Solution:

We have,

h(x)=x^2-3x+5

Putting x=2x+1, we get

h(2x+1)=(2x+1)^2-3(2x+1)+5

h(2x+1)=(2x)^2+2(2x)(1)+(1)^2-3(2x)-3(1)+5

h(2x+1)=4x^2+4x+1-6x-3+5

On combining like terms, we get

h(2x+1)=4x^2+(4x-6x)+(1-3+5)

h(2x+1)=4x^2-2x+3

Therefore, the required function is h(2x+1)=4x^2-2x+3.

A parallelogram has one angle that measures 135 degrees. What are the measures of other three angles in the parallelogram?
geniusboy [140]

Answer:

The measure of other three angles are 135° , 45° and 45°

Step-by-step explanation:

The opposite angles of a parallelogram are equal.

So if we consider a parallelogram ABCD ,

Angle A = Angle C

Angle B = Angle D

If we take angle A = 135° then angle C = 135°

SUM OF INTERIOR ANGLES OF A QUADRILATERAL IS 360°.

A+B+C+D=360°

135°+B+135°+D=360°

270°+B+D=360°

But B=D

So,2B=90°

B=45°

D=45°

So A = C = 135°

A = C = 135° B = D = 45°

A = C = 135° B = D = 45°
