what is the value of 5x+3 when x=4?​

25

Hi there !

6×7 - 3²×9 + 4³ =

  1. raise the numbers to power

= 6×7 - 9×9 + 64

  2. we perform the multiplications

= 42 - 81 + 64

  3.  we perform addition and subtraction

= (42 + 64) - 81

= 106 - 81

= 25

Good luck !

Answer:

-17

Step-by-step explanation:

-3^2×9+4^3

-3^2×3^2+64

-3^4+64

-81+64

-7x + 6 = 27

-7x = 21 (Subtract 6 from both sides)

x = -3 (Divide -7 from both sides)

Answer:

-10

Step-by-step explanation:

Answer:

x=8

Step-by-step explanation:

5(x – 2) = 30

Distribute:

5x - 10 =30

Add 10 to both sides:

5x = 40

Divide

x=8

Check your work:

5(8 - 2) =30

5(6) =30

5 * 6=30

30=30!

Final answer: x=8

y = 2x+4+3

y = 2x+7

Answer:

The answer is B.

Step-by-step explanation:

Given that vertically opposite angles are the same so the inner angle of the triangle is 40°.

Next, you have to find the other angle of the triangle. Assuming that total angles in a triangle is 180° so you have to subtract :

180° - 40° - 90° = 50°

So the value of x is 50°.

Answer:  see proof below

Step-by-step explanation:

Given: cos 330 = [tex]\frac{\sqrt3}{2}[/tex]

Use the Double-Angle Identity: cos 2A = 2 cos² A - 1

[tex]\text{Scratchwork:}\quad \bigg(\dfrac{\sqrt3 + 2}{2\sqrt2}\bigg)^2 = \dfrac{2\sqrt3 + 4}{8}[/tex]

Proof LHS → RHS:

LHS                          cos 165

Double-Angle:        cos (2 · 165) = 2 cos² 165 - 1

                             ⇒ cos 330 = 2 cos² 165 - 1

                             ⇒ 2 cos² 165  = cos 330 + 1

Given:                        [tex]2 \cos^2 165 = \dfrac{\sqrt3}{2} + 1[/tex]

                              [tex]\rightarrow 2 \cos^2 165 = \dfrac{\sqrt3}{2} + \dfrac{2}{2}[/tex]

Divide by 2:               [tex]\cos^2 165 = \dfrac{\sqrt3+2}{4}[/tex]

                             [tex]\rightarrow \cos^2 165 = \bigg(\dfrac{2}{2}\bigg)\dfrac{\sqrt3+2}{4}[/tex]

                             [tex]\rightarrow \cos^2 165 = \dfrac{2\sqrt3+4}{8}[/tex]

Square root:             [tex]\sqrt{\cos^2 165} = \sqrt{\dfrac{4+2\sqrt3}{8}}[/tex]

Scratchwork:            [tex]\cos^2 165 = \bigg(\dfrac{\sqrt3+1}{2\sqrt2}\bigg)^2[/tex]

                             [tex]\rightarrow \cos 165 = \pm \dfrac{\sqrt3+1}{2\sqrt2}[/tex]

             Since cos 165 is in the 2nd Quadrant, the sign is NEGATIVE

                             [tex]\rightarrow \cos 165 = - \dfrac{\sqrt3+1}{2\sqrt2}[/tex]

LHS = RHS [tex]\checkmark[/tex]

Answer :-

step by step explanation:-

Let the time be x

principal = rs 8000

Amount = rs 13824

rate = 20% p.a

A = P(1+r/100)^n

13824 = 8000 ( 1 + 20/100)^n

=> 13824/8000 = (120/100)^n

=> 13824/8000 = (24/20)^n

=> (24/20)³ = (24/20)^n

=> 3 = n

=> n = 3 years

hi!! here is your answer

Answer:

30

Step-by-step explanation:

4x + x + 30 = 180 (co interior angles are equal)

5x + 30 = 180

5x = 180 - 30

5x = 150

x = 150/5

x = 30

Answer:

3n+2=5n=8

n=8÷5

n=1.6

Answer:

n = 2

Step-by-step explanation:

Original Equation:

3n + 2 = 8

Subtract 2 from both sides.

3n = 6

Divide both sides by 3

n = 2

Answer:

  see attached

Step-by-step explanation:

Translation 12 units down puts each point 12 units lower on the graph than the position where it is currently shown. Segment RS is now shown on the line y=9. It will be translated straight down so it appears on the line y = 9-12 = -3.

Similarly, T has a y-coordinate of 2. Translated down 12, it will have a y-coordinate of y = 2-12 = -10.

The x-coordinates of all of the points remain the same.

The translation is shown in the attachment.

Answer:

1. y = -0.75x + 2

2. y = -1.8x - 7

3. y = -3x + 3

4. y = -11/7x + 56

5. y = -0.6x + 3

6. y = -2x - 14

7. y = 14x + 7

8. y = 2/8x - 4/3

9. y = x - 6

10. y = -1/3x + 4

Step-by-step explanation:

Question 1

3x + 4y = 8

4y = -3x + 8

y = -0.75x + 2

Question 2

9x + 35 = -5y

5y = -9x - 35

y = -1.8x - 7

Question 3

2y - 6 = -6x

2y = -6x + 6

y = -3x + 3

Question 4

-11x - 7y = -56

7y = -11x + 56

y = -11/7x + 56

Question 5

5y/3 = -(x - 5)

5y = -3(x - 5)

5y = -3x + 15

y = -0.6x + 3

Question 6

-2(2x + y) = 28

-4x - 2y = 28

2y = -4x - 28

y = -2x - 14

Question 7

-14x + y = 7

y = 14x + 7

Question 8

12y = (8x - 48)/3

36y = 8x - 48

y = 2/8x - 4/3

Question 9

(3x - 3y)/2 = 9

3x - 3y = 18

3y = 3x - 18

y = x - 6

Question 10

2x/3 + 4(y - 2) = 0

2x/3 + 2y - 8 = 0

2y - 8 = -2x/3

3(2y - 8) = -2x

6y - 24 = -2x

6y = -2x + 24

y = -1/3x + 4
