Someone please help quickly.......

Answer:

(2,-6)

Step-by-step explanation:

The solution set is any point to the left of the line. To find the solution set, test a point like (0,0).

$3(0) + 4(0) \leq -1\\0\leq -1\\False$

This means (0,0) is not in the solution set. The solution set is the region to the left of the line. Any point in this area will be a solution.

10%of 27

$= \frac{10}{100} \times 27$

$= \frac{27}{10} = 2.7$

1% of 27

$= \frac{1}{100} \times 27 = 0.27$

Indiras spring garden has half as many tulips as daffodils and three times as many hyacinths as tulips. If there are a total of

kow [346]

Indira is having 34 tulips, 68 daffodils and 102 hyacinths , altogether 204 flowers in her spring garden.

Given, In Indira's springtime garden, there are three times more hyacinths than tulips and half as many daffodils as tulips.

let the number of tulips be = x

the number of daffodils be = y

the number of hyacinths be = z

hence according to the question,

tulips are (x) = 1/2 (y) = y/2

hyacinths are (z) = 3(x) = 3x

therefore, total flowers = 204

tulips ₊ daffodils ₊ hyacinths = 204

y/2 ₊ y ₊ 3x = 204

substitute x value in the above equation.

y/2 ₊ y ₊ 3(y/2) = 204

take LCM

y ₊ 2y ₊ 3y = 408

6y = 408

y = 408/6

y = 68

hence the number of daffodils is 68.

now substitute y value in x = y/2

x = 68/2

x = 34

now substitute x value in z= 3x

z = 3(34)

z = 102

hence we get the number of tulips,daffodils and hyacinths as 34 , 68 and 102 respectively.
