4÷ 1/4 some one please help me

Answer:

Step-by-step explanation:

The safest way to begin is to remove the brackets.

-3 * - 5  -3x  ≥  3            Combine the left.

15 - 3x ≥  3                     Subtract 15 from both sides

-3x ≥ -12                         Divide by -3

x ≤ -12/-3

x ≤ 4

Notice when the ≥ turned around to ≤. It can only do this when you divide or multiply to get rid of a coefficient in front of number followed by a variable.

I've made you a graph of -3(-5 + x) ≥ 3. Notice the graph shows that the largest value can be 4 just as the solution suggests.

Slope=-5/2

Step-by-step explanation:

First, you need to convert the equation from standard from (Ax+By=C) to slope-intercept form (y=mx=b)

5x+2y= -10

-5x       -5x

2y= -5x-10

There are 5005 ways the volunteers can be selected

The given parameters are:

Since there is no restriction, as to who can be selected;

The total number of selection is calculated using the following combination formula

[tex]^nC_r = \frac{n!}{(n -r)!r!}[/tex]

Where:

[tex]n = 5 + 10=15[/tex]

[tex]r = 6[/tex]

So, we have

[tex]^{15}C_6 = \frac{15!}{9!6!}[/tex]

This gives

[tex]^{15}C_6 = 5005[/tex]

Hence, there are 5005 ways the volunteers can be selected

Answer:

No it isn't.

Step-by-step explanation:

if parallel they should sum up to 180 degree

to check if does or not, 126 + 44 = 170 degree

nope the line l is not parallel to m

Answer:

no

Step-by-step explanation:

angle of straight line =180°

if 44+126=180 then the line is straight but because the sum of it is 170° line l and m are not paralle.

Answer:

Solution:

Answer:

Step-by-step explanation:

This is simple: we need to only do 2 steps

1) Convert to feet

2) Get the area

1) Converting to feet is just

[tex](7*3, 4*3)\\[/tex] (ignore the use of this it's just to show the differnt things to multiply

Now we have a length of 21 and a width of 12 FEET.

2) To solve for the area, we need to multiply both dimensions.

[tex]21*12=252[/tex]

So the answer is 252^2 FEET (DONT FORGET THE UNIT SQUARE FEET)

Answer:

Step-by-step explanation:

f(x) means the same thing (just about) as y. Think of it as the y value.

f(2) means that wherever you see an x on the right, you make it into a 1.

So f(2) means 4(2) - 6 = 8 - 6 = 2

A us the correct answer. Everything else cannot be made to produce 2 or at least not the right way

Answer:

9 months

Step-by-step explanation:

Let x = number of months with withdrawal

Since he takes out 75 for each month, multiply x by 75 like this: 75x

This is being taken out of the 800, so subtract 800 by 75x

800 - 75x

This has to be equal to 125 since Mick does not want the account to be less than 125

800 - 75x = 125

Let's subtract 800 from both sides

800 - 75x = 125

- 800            - 800

-75x = -675

Then, divide both sides by -75 to isolate the x variable

-75x/-75 = -675/-75

x = 9

The max number of months is equal to 9

Answer:

parallel

Step-by-step explanation:

Answer:

lines are parallel and m = 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

14x = 2y - 6 or

2y - 6 = 14x ( add 6 to both sides )

2y = 14x + 6 ( divide through by 2 )

y = 7x + 3 ← in slope- intercept form

with slope m = 7

------------------------------

[tex]\frac{8}{7}[/tex] = y - 7x or

y - 7x = [tex]\frac{8}{7}[/tex] ( add 7x to both sides )

y = 7x + [tex]\frac{8}{7}[/tex] ← in slope- intercept form

with slope m = 7

Since slopes of both lines are equal, both m = 7 then lines are parallel

Answer:

17

Have a great day!

Answer:

x - y = 17

Step-by-step explanation:

Given information,

→ x = 7

→ y = -10

Solving the expression,

→ x - y

→ 7 - (-10)

→ 7 + 10

→ 17

Thus, the answer is 17.

Answer:

  k = 4.75

Step-by-step explanation:

If (13 -√131)/4 is a root of the equation, then its conjugate, (13 +√131)/4 is also a root. The product of the roots is k/2, where 2 is the leading coefficient.

The product is ...

  k/2 = ((13 -√131)/4) × ((13 +√131)/4) = (13² -131)/4² = 38/16

Then the value of k is ...

  k = 2(38/16) = 19/4

  k = 4.75

_____

The attached graph shows that (13 -√131)/4 is a root of the quadratic when k = 4.75.

Answer:

Step-by-step explanation:

Rearrange  [tex]2x=3y+4[/tex]   to make y the subject:  [tex]y=\frac{1}{3} (2x-4)[/tex]

Just working with the denominator of [tex]\frac{9^x}{27^y} [/tex] to rewrite it using [tex]x[/tex]:

                  [tex]27^y=27^{\frac{1}{3}(2x-4)}[/tex]

                        [tex]=(27^{\frac{1}{3}})^{(2x-4)} [/tex]

                        [tex]=3^{(2x-4)} [/tex]

                        [tex]=3^{2x}[/tex] ÷ [tex]3^4[/tex]

                        [tex]=(3^2)^x[/tex] ÷ 81

                        [tex]=\frac{9^{x}}{81} [/tex]

Substitute this into [tex]\frac{9^x}{27^y} [/tex] and solve:

So [tex]9^x [/tex] ÷ [tex]27^y=9^x[/tex] ÷ [tex]\frac{9^{x}}{81} [/tex]

                  [tex]=9^x \times \frac{81}{9^x} [/tex]

                  [tex]=81[/tex]

Answer:

Step-by-step explanation:

To do this, we first divide 2.87 by 3.50. This gets us 0.82. So we now know that 2.87 is 82% of 3.50. But we're trying to find the reduced amount. So we now Do 100%-82% (82% being 2.87) to get 18%. So the answer is 18%. To make sure we are right, we do 18% of 3.50 to get 0.63 cents. We then take 3.50 and subtract 0.63 to get 2.87. So it reduced by 18%
