Step-by-step explanation:

cuz i know stuff (its simple subtraction)

Answer:

a)  ( r+ s) (x)  = 3 x + 9

b)   ( r . s ) (x) =  2 x² + 13 x +20

c) ( r- s) (x)  = -1 -x

Step-by-step explanation:

Step(i):-

Given that r(x) = x +4 and s(x) =  2x + 5

a)   ( r+ s) (x)  = r(x) + s(x)

                    = x +4 + 2x +5

                   = 3 x + 9

    ( r+ s) (x)  = 3 x + 9

b)

    ( r . s ) (x)  = r(x) . s(x)

                    = (x+4) . ( 2x +5)

                   = x ( 2x +5) + 4( 2x +5)

                  = 2 x² + 5 x + 8 x +20

                 = 2 x² + 13 x +20

( r . s ) (x) =  2 x² + 13 x +20

c)

 ( r- s) (x)  = r(x) - s(x)

               =  (x+4 - ( 2x +5)

              = x +4 - 2x -5

            = -x -1

( r- s) (x)  = -1 -x

Answer:

4. His classmate's daily allowance is of P100.

5. She used 25% of the sheets of art paper.

Step-by-step explanation:

4. Manuel, a son of a school janitor, does not ask for more. He has a daily

allowance of P10 a day which is 20% of his classmate's daily allowance. How much is his classmate's daily allowance?

An allowance of P10 a day is 20% of his classmate's allowance, that is, 20% of x. So

[tex]0.2x = 20[/tex]

[tex]x = \frac{20}{0.2}[/tex]

[tex]x = 100[/tex]

His classmate's daily allowance is of P100.

5. Carla, a grade six pupil , has 24 sheets of art paper for his project in Math. If 6 sheets of art paper were used by Carla, what percent of the sheets of art paper did she use?​

She used 6 sheets, of the 24. So

[tex]P = \frac{6*100}{24} = \frac{100}{4} = 25[/tex]

She used 25% of the sheets of art paper.

Step-by-step explanation:

Let $x be the price of an apple and $y be the price of an orange.

5x + 4y = 10

5x + 5y = 11

btw the solution is

y = 1

x = 6/5

Answer:

A solution to a linear equation means that the ordered pair is a point that lies on that line.

If someone were to say (2,5) is a solution to the equation y= 2x+3, you could check them by plugging in 2 where the variable "x" and seeing if y =5.

In this case,

y= 2(2)+3

y=7

(2,5) is not a solution.

Answer:

  (2, 3)

Step-by-step explanation:

Compare the given equation ...

  y = (x -2)^2 +3

to the vertex form ...

  y = (x -h)^2 +k

You can see that h=2 and k=3.

The vertex of the parabola is (h, k) = (2, 3).

Answer:

Step-by-step explanation:

D

Answer:

In Geometry, there are five fundamental angle pair relationships:

Complementary Angles.

Supplementary Angles.

Adjacent Angles.

Linear Pair.

Vertical Angles.

The measure of the angle u and angle t will be 29 degrees.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The angle u is congruent to angle t.

From the diagram, angle t, angle u, and angle 122 are supplementary angles. Then the equation is given as,

∠t + ∠u + 122° = 180°

∠t + ∠t  = 58°

2∠t = 58°

∠t = 29°

The measure of the angle u and angle t will be 29 degrees.

Answer:

 sin 3 θ  = 3 sin θ  - 4 sin³θ

Step-by-step explanation:

Step(i):-

Given    sin 3 θ  

            =  sin ( 2θ + θ )

apply trigonometric formula

         sin ( A + B) = sin A cos B + cos A sin B

        sin 2 A = 2 sin A cos B

        Cos 2 A = 1 - 2 sin² A

        cos ² A - sin ² A = 1

Step(ii):-

    sin 3 θ  =     sin ( 2θ + θ )

               =  sin 2θ cosθ +  cos2θ sin θ

              = 2 sin θ cos θ cos θ +( 1 - 2 sin² θ )sin θ

              = 2 sin θ (cos² θ ) + sin θ- 2 sin³ θ

              = 2 sin θ ( 1- sin²θ) + sin θ- 2 sin³ θ

              = 2 sin θ - 2sin³θ +  sin θ- 2 sin³ θ

              = 3 sin θ  - 4 sin³θ

Final answer :-

 sin 3 θ  = 3 sin θ  - 4 sin³θ

3x-4y=18

xy=18 ans

Answer:

X=2/5

Y=-21/5

Step-by-step explanation:

solve your system by substitution.

3x−4y=18;9x−2y=12

Step: Solve3x−4y=18for x:

3x−4y=18

3x−4y+4y=18+4y(Add 4y to both sides)

3x=4y+18

3x/3=4y+18/3

(Divide both sides by 3)

x=4/3y+6

Step: Substitute 4/3y+6 for x in 9x −2y=12:

9(4/3y+6)−2y=12

10y+54=12(Simplify both sides of the equation)

10y+54+−54=12+−54(Add -54 to both sides)

10y=−42

10y/10=-42/10 .   (Divide both sides by 10)

y=-21/5

Step: Substitute

21/5 fory in x= 4/3y+6

x= 4/3y (-21/5) +6

  X=2/5 (Simplify both sides of the equation)

           Answer:

          X=2/5

          Y=-21/5

Answer:

3.5 miles

Step-by-step explanation:

Step one:

given data

Samuel runs around a 1-mile track in 10 minutes

Samuel's speed is

speed= distance/time

speed= 1/10= 0.1 miles per minute

Sophia runs around the same track in 10 minutes

Hence Sophia's speed is also = 0.1 miles per minute

Step two:

Given that the time is 35 minutes, and their speeds are 0.1 miles per minute, we can find the distance from

speed= distance/time

distance= speed*time

distance= 0.1*35

distance= 3.5 miles

Step-by-step explanation:

Let's solve for x.

−3x+2b>8

Step 1: Add -2b to both sides.

2b−3x+−2b>8+−2b

−3x>−2b+8

Step 2: Divide both sides by -3.

-3x/-3>-2b+8/-3

Answer:

It doesn't specify so . . .

If its the bottom right it's 90°

If it's the bottom left it's 48°

Step-by-step explanation:

Ok so first, the triangle is a right triangle

meaning there's  a 90° angle

Great, We now know two angles

90° and 42°

All angles of a triangle add up to 180

so we make it into an equation

and solve it.

42 + 90 + 6x = 180

132 + 6x = 180

-132         -132

6x  = 48

Divide by 6 to leave x by itself.

x = 8

Now we can see what 6x actually is

6 ( 8 ) = 48

Note: This is for the bottom left angle. 6x
