So I have number 1 for you.
She is wrong because 12 is not y2 (second sub) . It is actually supposed to be 4-12 / 7-9.

Marcia bought a bag of red white and blue balloons for the party there were 49 balloons in the bag if there are twice as many re

DedPeter [7]

Answer:

Red color= 28 balloon

Blue color= 14 balloon

White color= 7 balloon

Step-by-step explanation:

Given: There are 49 balloons

As given, there are 2 red balloon equal to the number of blue balloon

∴ $2 red= blue\ balloon$

Again given, there are 1/2 white balloon equal to the number of blue balloon.

∴ $\frac{1}{2} \ white= blue\ balloon$

As above equation, we can understand that:

$2\ red= \frac{1}{2} \ white\ balloon$

multiplying both side by 2

⇒ $4\ red= white\ balloon$

which mean, if we have 2 blue balloon then we will have 4 red and 1 white balloon.

∴ Total combination of all color of balloon= $2+4+1= 7$

Now, checking how many number of times combination can we have in 49 balloon.

$\frac{49}{7}= 7 \ times$

Next, finding number of balloon in each color.

Red color= $4\times 7= 28\ balloon$

Blues color= $2\times 7= 14\ balloon$

White color= $1\times 7= 7\ balloon$

Find the slope of (-2,-5) and (8,-5) And find the slope of the line passing through the points (4,9) and (4,-7)

DochEvi [55]

Answer:

Part 1) $m=0$

Part 2) The slope is undefined

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

Part 1

we have

$A(-2,-5)\ B(8,-5)$

Substitute the values

$m=\frac{-5+5}{8+2}$

$m=\frac{0}{10}$

$m=0$ ----> is a horizontal line (parallel to x-axis)

Part 2

we have

$A(4,9)\ B(4,-7)$

Substitute the values

$m=\frac{-7-9}{4-4}$

$m=\frac{-16}{0}$ ----> is a vertical line (parallel to y-axis)

The slope is undefined
