Answer:y=35x+11

Step-by-step explanation:y=Mx+b

Answer:

3

Step-by-step explanation:

since both triangles are similar, set up a ratio

[tex]\frac{4}{2}[/tex]=[tex]\frac{6}{s}[/tex]

cross multiply

4s=12

divide

4s=12

/4   /4

s=3

Answer:

a)

(i) 43, 56

(ii) -1,3

b)-27

c) -21 +4n

Step-by-step explanation:

For a,i, you can see that it decreses by 7 each time so you subtract 7 from 50 to get 43, then you subtract 7 from that to get 56. For a,ii it increases by 4 each time so you add 4 to -5 to get -1, then add 4 to that to get 3. For b, because it is the 15th term you are looking for, you can plug 15 into the equation as n so 78-7n to 78- 7*15, 78-105, -27. For c, you know that each time it increases by 4, so you know you add 4n, and then for the base, you have to find the term before -17 so you subtract 4 to get -21. Put it together and get -21+4n.

Answer:

40 minutes

Step-by-step explanation:

To find it taes to clear and set one table divide time by the amount of tables. 18/9=2. It takes 2 minutes per table. To find the answer for 20 tables, you have to multiply 20 by 2. It takes 40 minutes to set and clear 20 tables.

Answer:

Step-by-step explanation:

x²-2=2⅔ +2-⅔

x^2 = 2^1 + 2⅔ +2-⅔

x^2 =   4.21736

x = 2.0536.

Plug this into 2x^3 - 6x:

= 2(2.0536)^3 - 6(2.0536)

= 5

So 2x^3 - 6x = 5.

answer:

[tex]x1 = - \sqrt{6} \\ x2 = \sqrt{6} [/tex]

Step-by-step explanation:

[tex]x ^{2} - 2 = \frac{8}{3} + 2 - \frac{2}{3} [/tex]

[tex]x^{2} - 2 = 4[/tex]

[tex]x^{2} = 4 + 2[/tex]

[tex]x^{2} = 6[/tex]

[tex]x = - \sqrt{6} \\ x = \sqrt{6} [/tex]

[tex]x1 = - \sqrt{6} \\ x2 = \sqrt{6} [/tex]

Answer:

Step-by-step explanation:

y+11<30

subtract 11 from both sides

y+11-11<30-11

y< 19

choice A

Step-by-step explanation:

y + 11 < 30       Original inequality

y + 11 - 11 < 30 - 11    Isolating the variable

y < 19                The answer / Simplification

Answer:

D. (-1, -10)

Step-by-step explanation: I put your question into a math calculator and got this as your answer. Good luck!

Step-by-step explanation:

5x + 6x + 3x

= 14x.

Now we compare the expressions with the result:

11x + 3x = 14x. (correct)

14x + x = 15x. (incorrect)

2(3x + 4x) = 2(7x) = 14x. (correct)

3x(2 + 1) + 5x = 3x(3) + 5x = 9x + 5x = 14x. (correct)

5x + 3(2x + x) = 5x + 3(3x) = 5x + 9x = 14x. (correct)

Hence our answers are the 1st, 3rd, 4th and 5th.

Answer:

13

Step-by-step explanation:

2x+x=39

3x=39

divide both sides by 3 and then you get 13

Answer:

x = 13.6

Step-by-step explanation:

Here, we want to find the value of x

to find the value of x. we are going to use the sine rule

It states that the ratio of the sine of an angle to the measure of the side facing the angle is fixed for a triangle

In this case;

11/ sin 27 = x/ sin 34

x = 11 sin 34/sin 27

x = 13.6

Answer:

The slowest train goes at 86 mph and the fastest train goes at 96 mph.

Step-by-step explanation:

Distance and Speed

Assume x is the speed of the slowest train, therefore the speed of the fastest train is x+10.

The distance is calculated as:

d = vt

Where v is the speed and t is the time.

The distance traveled by each train in 5 hours is:

Slowest: 5x

Fastest: 5(x+10)

The sum of both distances is 910 miles:

5x + 5(x + 10) = 910

Operating:

5x + 5x + 50 = 910

10x = 910 - 50 = 860

x = 860/10

x = 86

The slowest train goes at 86 mph and the fastest train goes at 96 mph.

Answer:

"The expression will always equal m" is true about the quotient of [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]

Step-by-step explanation:

Let us solve the question

∵ The expression is [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]

→ In the division of fractions, we change the division to multiplication

   and reciprocal the fraction after the division sign

∵ The reciprocal of  [tex]\frac{1}{n}[/tex] is [tex]\frac{n}{1}[/tex]

∴  [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] =  [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex]

→ In the multiplication of fractions, we can simplify the terms in

    the numerators by the terms in the denominators

∵ There is n in the numerator and denominator

∴ Cancel n up and down

∴  [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = [tex]\frac{m}{1}[/tex]

∴  [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = m

∴  [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] = m

∴ The quotient is m

∴ The expression will always equal m

Answer:

80 i think

Step-by-step explanation:

32.3=80

Step-by-step explanation:

Amount of money saved : spent = 2 : 3.

Since amount of money saved = £32,

Amount of money spent = £32 * (3/2) = £48.

Total amount of money = £32 + £48 = £80.

Therefore I received £80 for my birthday.

Answer:

8.333% error

Step-by-step explanation:

using percent error formula

(actual - expected) / expected *  100 %

actual = 65

expected = 60

plug

(65-60)/60 * 100%

= 8.33 %

Answer:

a = 249 and b = 1.16

Step-by-step explanation:

Consider the provided information.

The exponential function for growth is:  [tex]y=a(1+ r)^x[/tex]

Here, a is the initial value and r is the rate of change.

It is given that the number of birds is 249.

It means a = 249

The rate is given 16%

r=0.16

Put the value of a and r in the above formula.

[tex]y=249(1+0.16)^x[/tex]

[tex]y=249(1.16)^x[/tex]

Now we will compare it with the exponential function form [tex]y=ab^x[/tex]

Therefore, a = 249 and b = 1.16

Step-by-step explanation:

Given

x² + 13x + 12

= x² + ( 12 + 1) x + 12

= x² + 12x + x + 12

= x ( x + 12 ) + 1 ( x + 12)

= (x + 12) (x + 1)
