Answers

Answer:

Step-by-step explanation:

Substitution  method:

y= -2x + 2

x - 2y = 6

so y = (-2x + 2)

Substitute into y

Hence x - 2y = 6 is:

x + 2x +2 = 6    (+2x because there was - in the equations so -×- = +)

3x + 2=6

Then bring 2 to the other side so

3x = 6-2

3x = 4

x = 3/4 or 0.75

To find y :

y= (-2 × 3/4) + 2

y = -1.5 +2

y = 0.5

That's all I can do for now!

Answers

Answer:

k=2

Step-by-step explanation:

the equation of  straight line passing through the two points (a , b) and (c , d) is  

Now f(x) passes through (-4 , 0) and (0 , 4)

the equation is  

y=x+4

Now g(x) passes through (-2 , 0) and (0 , 4)

the equation is  

y=2x+4

here f(x)=x+4 and g(x)=2x+4

clearly g(x)=f(2x)

therefore k=2

A data set has a mean of 7, a median of 5, and a mode of 8. Which of the numbers (7, 5, or 8) must be in the data set?


If possible, please explain in words, thank you. :)

Answers

5 must be in the data set: median means it’s the middle number in the set. so if the data was [2,3,5,6,7], 5 is the median.
8 has to be in the data set because 8 had to be there to be a mode were you can have 5 as the median if the set was like this 234678 because 4&6 both are in the middle so you have to do the middle of that which is 5 so that’s the median without having the number 5.

Each bag must have the same number of toy cars in it.

Each bag must have the same number of toy helicopter in it.

All bags must have the same number of toys in it.

a) How many bags will contain toy cars?

b) How many bags will contain toy helicopters?

Answer:

Think of highest common factor of 56 and 77

Both numbers are divisible by 1, 2, and 7 and the highest common factor is 7

56 ÷ 7 = 8

77 ÷ 7 = 11

There are 8 bags that contain equal numbers of toy cars and 11 bags that contain equal number of helicopter toy
