Please help me you have to find the slope

Answer:

1.23=4f+5

=4d=23-5=18

=d=18/4=4.5

2.3w+15=45

=3w=45-15=30

=w=10

Answer:

choice 3) 50 in

Step-by-step explanation:

A = 625(Pi) in^2

radius = (sq rt 625)(Pi)/Pi

radius = 25

d = 2(radius)

d = 50 in

Answer:

x = -17

y = -68

Step-by-step explanation:

x - y = 51

y/x = 4  so we can say that y = 4x

using substitution:

x - 4x = 51

-3x = 51

x = -17

find 'y':

-17 - y = 51

-y = 68

y = -68

check:

-17 - (-68) = 51

51 = 51

-68/-17 = 4

4 = 4

Answer:

  10

Step-by-step explanation:

The angle bisector divides the sides proportionally.

  y/25 = 8/20

  y = 25(8/20) . . . . multiply by 25

  y = 10

Step-by-step explanation:

c^2 = b^2 + a^2

c^2 / hypotenuse = 16^2 + 30^2

c^2 = 256 + 900

c^2 = 1156

c =

[tex] \sqrt{1156} [/tex]

c = 34 #

Answer:

9.09%

Step-by-step explanation:

To find percent decrease you have to use this equation:

[tex]Percent Decrease = \frac{Initial -New}{Initial} x 100[/tex]

Initial = 49.5

New = 45

Plug in and solve:

[tex]PD = \frac{49.5-45}{49.5} x 100\\\\PD = \frac{4.5}{49.5} x 100 \\\\PD = 0.0909 x 100\\\\PD = 9.09[/tex]

The percent decrease is 9.09%

Hope this helps!!

Complete Question:

There are 10 marbles. What is the probability of drawing 2 blue marbles if the first marble is NOT placed back in the bag before the second draw.

2 yellow, 3 pink, 5 blue    

Answer:

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]

Step-by-step explanation:

Given

[tex]Blue = 5[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 10[/tex]

When the first blue marble is selected, the probability is:

[tex]P(B_1) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{5}{10}[/tex]

Since the first marble is not returned, we have the following marbles left

[tex]Blue = 4[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 9[/tex]

The probability of picking a second blue marble is:

[tex]P(B_2) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{4}{9}[/tex]

So, the required probability is:

[tex]P(B_1\ and\ B_2) = P(B_1) * P(B_2)[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5}{10} * \frac{4}{9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5*4}{10*9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{20}{90}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]

Answer:

x/121 + y/9 = 1

Step-by-step explanation:

The major axis is 22 units long, in a horizontal line, and the center is in the middle of the major axis line segment. The center is at the origin. The distance of the whole axis is 22, and its endpoints are 11 units from the center. The axis length is 2a = 22, so a = 11.

Becasue the major axis is horizontal, this ellipse is wider than it is tall.

The minor axis is perpendicular to the major axis and it always shoter (hence the name 'minor'). In this case, it is vertical, is 6 units long, so we say that 6 = 2b, and b = 3.

The ellipse center is (h,k). But in this case, the center is the origin, so h = 0 and k = 0.

The equation for a horizontal ellipse is (x-h)²/a² + (y-k)²/b² = 1, a>b

(x-0)²/11² + (y-0)²/3² = 1

*** x/121 + y/9 = 1

The equation for a vertical ellipse is (x-h)²/b² + (y-k)²/a² = 1, a>b

If the bigger denominator is under 'x' term the ellipse is horizontal, with the longer axis being horizontal.

If the bigger denominator is under the 'y' term, the ellipse is vertical, with the longer axis being vertical.

I'm including 2 files.

The 'brainly ellipse' is form this particular problem.

The 'General Ellipse Info' is a collection of my personal math notes on elleipses.

Answer: Slope of line = [tex]\frac{1.2}{2}[/tex]

Graph- see picture.

Step-by-step explanation:

Graphs are graphed using y=mx+b

Slope (m) is written as [tex]\frac{rise}{run}[/tex], and y coordinate is up and down, x is left & right.

The y coordinate adds 1.2 every time, so the rise is 1.2.

The x coordinate adds 2 every time, so the run is 2.

The y intercept (b) simply means where the line intercepts the y axis.

It is given that the y intercept is 0.

So, the graphing equation: y= [tex]\frac{1.2}{2}[/tex]x

We don't need to put the y intercept because it is 0!

The graph is attached!

Answer:

1.   2x + 8y = 10xy

2.   13ab + 15ab = 28ab

Step-by-step explanation:

  This is because for question 2 the "a" and "b" stay together since it's on 13 and 15. So that is why you would get 28ab. For question 1 it's basicly the same but instead, you combine the two to get your answer.

Hope this helps.
