Step-by-step explanation:

Answer:

[tex](4,5)\ or\ x=4,y=5[/tex]

Step-by-step explanation:

[tex]We\ are\ given:\\y=2x-3\\y-9=-x\\Now,\ lets\ separate\ all\ the\ constant\ terms\ to\ the\ RHS\ and\ the\ variable\\ terms\ to\ the\ LHS.\\Hence,\\y-2x=-3\\y+x=9\\By\ subtracting\ the\ two\ equations:\\(y-2x)-(y+x)=(-3)-(9)\\Hence\ lets\ simplify\ this\ main\ equation: \\y-2x-(y+x)=-3-9\\y-2x-y-x=-12\\-3x=-12\\x=\frac{-12}{-3}=4\\\\Now,\ lets\ consider\ the\ second\ equation\ in\ the\ solution:\\y-9=-x\\Substituting\ x=4,\\y-9=-(4)\\y-9=-4\\y=-4+9\\y=5\\[/tex]

[tex]Now,\\We\ get\ the\ solution\ to\ this\ system\ of\ equations:\\x=4,y=5\\By\ putting\ this\ as\ a\ co-ordinate\ pair (x,y):\\(4,5)[/tex]

Answer:

The solution of the system of equations will be:

[tex]y=5,\:x=4[/tex]

Step-by-step explanation:

Given the system of equation

[tex]\begin{bmatrix}y=2x-3\\ y-9=-x\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y-2x=-3\\ y+x=9\end{bmatrix}[/tex]

so

[tex]y+x=9[/tex]

[tex]-[/tex]

[tex]\underline{y-2x=-3}[/tex]

[tex]3x=12[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}y-2x=-3\\ 3x=12\end{bmatrix}[/tex]

solve 3x=12 for x

[tex]3x=12[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}=\frac{12}{3}[/tex]

[tex]x=4[/tex]

[tex]\mathrm{For\:}y-2x=-3\mathrm{\:plug\:in\:}x=4[/tex]

[tex]y-2\cdot \:4=-3[/tex]

[tex]y-8=-3[/tex]

Add 8 to both sides

[tex]y-8+8=-3+8[/tex]

[tex]y=5[/tex]

Thus, the solution of the system of equations will be:

[tex]y=5,\:x=4[/tex]

Answer:

14.25

Step-by-step explanation:

95 x 0.85 = 80.75

95-80.75 = 14.25

Answer:

A straight line passing through the origin

Step-by-step explanation:

A proportional relationship will have a particular quantity being related to another

For example, the relationship might be inverse or direct

In this case, we can have a straight line graph that passes through the origin

A straight line graph that passes through the origin would show the proportional relationship as it has no slope whatsoever

Answer:

Step-by-step explanation:

Wheelbarrows  is 30/3 = 10

Pair of shoes is (18 - 10) /2 = 4 so one shoe is 2

2 Seed bags is 4 - 2 = 2 so one bag is 1

Answer is 1(seed baf) + 10(wheelbarrows X 2(shoe) = 21

Answer:

4^0 + 2 x 3 - 2 = 5

2^2 + 10 - 3 x 2 = 8

9 + 3^2 - 1 x 4 = 14

Answer: 2000

Step-by-step explanation:

The following can be gotten from the question:

Principal = Unknown

Rate = 6%

Time = 6 years.

Interest = 720

Note that: Interest = PRT / 100

720 = (P × 6 × 6) / 100

720 = 36P / 100

720 × 100 = 36P

72000 = 36P

Principal = 72000 / 36

Principal = 2000

The amount that he borrowed is 2000.

Answer:

for 80cm

1 =4 cm

x=80cm

4 cmx=80 cm

4 cm. 4 cm

x=20 days

Step-by-step explanation:

1 is equal to 4cm

there x is equal to 80cm

cross multiply

then divid though by 4 because it has letter x

and finally you 20 days as your answer.

Answer:

[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]

Step-by-step explanation:

Given

[tex]Meal = \{Oatmeal, Eggs, Pancakes\}[/tex]

[tex]Beverage = \{Coffee, Tea\}[/tex]

Required

Determine the sample space

The sample space is a list of combination of 1 meal and 1 beverage.

Because one individual can order only one of the meals and one of the beverages at any one time, then no two orders can be the same

The sample space (S) is as follows:

[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]

Answer:

31°

Step-by-step explanation:

90° - 59° = 31°

31° + 59° = 90°

Answer:

Step-by-step explanation:

Use PEMDAS

First you do the multuplication of

1/6*(-5/3)=-5/18

Next you do the addition

5+(-5/18)= 90/18-5/18= 85/18

Answer:

the student is wrong

Step-by-step explanation:

the og directions said 3 scoops / 1 gallon / 1 pitcher. if you are using 12 scoops, then the gallons of water will be proportional, meaning 3x4=12 scoops / 1x4=4 gallons / 1x4=4 pitchers. if you x4 to one of them, then the directly porportinal values also have to be multiplied by the same number, hence making the student wrong since they should have 4 gallons for 12 scoops

Answer:

  -108

Step-by-step explanation:

About the easiest way to do this for small values of n is to compute each of the terms using the given recurrence relation.

  [tex]a_1=4\\\\a_2=-3a_1=-3(4)=-12\\\\a_3=-3a_2=-3(-12)=36\\\\a_4=-3a_3=-3(36)=-108\\\\\boxed{a_4=-108}[/tex]

_____

Alternate solution

You recognize that the recurrence relation describes a geometric sequence with a first term of 4 and a common ratio of -3. The n-th term of a geometric sequence is ...

  [tex]a_n=a_1\cdot r^{n-1} \qquad\text{for first term $a_1$ and common ratio $r$}[/tex]

Then the 4th term will be ...

  [tex]a_4=4\cdot(-3)^{4-1}=4\cdot(-27)=-108[/tex]

Answer: 10% of 65.9

Step-by-step explanation:

Given:

Table of values.

To find:

The equation in point slope form.

Solution:

From the given table it is clear that, the relationship is linear because the rate of change is constant because if x-value increases by 2 then y-values increases by 16.

Consider any two points from the table, i.e., (2,16) and (4,32).

[tex]Slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]Slope=\dfrac{32-16}{4-2}[/tex]

[tex]Slope=\dfrac{16}{2}[/tex]

[tex]Slope=8[/tex]

The point is (2,16) and the slope is 8, so the point slope form is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-16=8(x-2)[/tex]

Therefore, the relationship is linear and point slope form is [tex]y-16=8(x-2)[/tex].

Answer:

y - 16 = 8(x - 2)

Complete Question

Mr Brown has 2 children are going to london by train

1 adult costs £24 and child ticket costs 12

The Family Railcard offers:

1/3 off adults tickets and 60% off child ticket

What is the total cost of tickets when Mr Brown uses the Family Railcard

Answer:

£25.60

Step-by-step explanation:

From the question:

1 adult costs £24

The Family Railcard offers:

1/3 off adults tickets.

Hence:

1/3 × £24 = £8

The cost for Mr Brown = £24 - £8

= £16

Child ticket costs £12

The Family Railcard offers:

60% off child ticket

Hence = 60% × £12

= 60/100 × £12

= £7.2

The cost for 1 child = £12 - £7.2

= £4.8

The total cost of tickets when Mr Brown uses the Family Railcard is:

Cost for Mr Brown + Cost for his 2 Children

£16 + 2 × £4.8

£16 + £9.6

= £25.60
