Find the Y-intercept and x-intercept of the line: 4x- 6y=21
zimovet [89]

Answer:

Step-by-step explanation:

4x-6y=21

divide by 21

\frac{4x}{21} -\frac{6y}{21} =1\\or~\frac{x}{\frac{21}{4} } +\frac{y}{-\frac{7}{2} } =1\\x~intercept =\frac{21}{4} =5.25 \\y~intercept=-\frac{7}{2} =-3.5

Please I need help with this Question
frutty [35]

Answer:

The data set with the greater range is the Girls

The greater median is the Girls at 110

Step-by-step explanation:

The range is the difference between the largest and smallest values.

As the largest value for the boys is 120 and the smallest is 60, the range would be 60

As the largest value for the girls is 150 and the smallest is 70, the range would be 80.

This means that the Girls have the greater range

The median is the number in the middle when the data is in ascending order.

As we have an even number, we will have to find the middle value between 5 and 6. To do this, we can add them together and divide them by 2.

The 5th boy in ascending order is 90 and the 6th boy is 90.

(90+90)/2=90

The 5th 5irl is 100 and the 6th girl is 120

(100+120)/2=110

This means that the median is greater for the Girls.

Its a word problem in algebra 1 that i need help on step by step ?
Luden [163]

Answer:

Cost of one rose bush =  $2 and cost of 1 geranium = $11

Step-by-step explanation:

lets assume cost of one rose bush = $x

lets assume cost of one geranium = $y

Given that Norachai spent $13 on 1 rose and 1 geranium

⇒ 1 × (cost of one rose bush) + 1× (cost of one geranium) = 13

⇒ 1x + 1y = 13     ----------------------------equation 1

Also given that Castel spent $46 on 1 rose bush and 4 geraniums

⇒1 × (cost of one rose bush) + 4× (cost of one geranium) = 46

⇒ 1x + 4y = 46    ----------------------------equation 2

Now we are having following two equations which will be used to find the value of x and y

1x + 1y = 13     ----------------------------equation 1

1x + 4y = 46    ----------------------------equation 2

lets modify equation 1 to get value of  y in terms of x and name that equation as equation 3

1x + 1y = 13     ----------------------------equation 1

⇒ y = 13 - x    -----------------------------equation 3

On substituting value of y from equation 3 in equation 2 we get

1x + 4 × ( 13 - x ) = 46

⇒ x + 52-4x =46

⇒ -3x = 46-52

⇒     x = (-6)/(-3) = 2

on substituting calculated value of x that is 2 in equation 3 we get

y = 13 -2 = 11

so on solving the equations we get x = 2 and y = 11.

Hence cost of 1 rose bush = $x = $2 and cost of 1 geranium = $y = $11
