what expression is equivalent to 5x(2-3x)+4(2-3x)+2-3x

Answer:

Step-by-step explanation:

Answer:

x = 10

Step-by-step explanation:

to find the measure of angles we first need to find the value of x

The sum of interior angles in a triangle is equal to 180

9x + 7x + 2x = 180 add like terms

18x = 180 divide both sides by 18

x = 10 to find angle measures replace x with 10 in each representative like:

m<L = 9x and 9*10 = 90 and so on

  (1, 1.4), (10, 14), (50, 70)

Step-by-step explanation:

To obtain another point where the values have the same proportional relationship, multiply both coordinate values by the same factor.

  using a factor of 1/5: Y = (1, 1.4)

  using a factor of 2: Y = (10, 14)

  using a factor of 10: Y = (50, 70)

Answer:

750 units

Step-by-step explanation:

As given in question,

speed of solution = 30 mL/hr

1 L of solution contains heparin = 25000 units

=> 1000 mL of solution contains heparin = 25000 units

= > \ \textrm{1 mL of solution contains heparin}\ =\ \dfrac{25000}{1000}\ units=> 1 mL of solution contains heparin =

1000

25000

units

= 25 units

Hence, 30 mL of solutions contains heparin = 30 x 1 mL of solution contains

heparin

= 30 x 25

= 750 units

Hence, heparin administered per hour = 750 units

If Lucy got 5/6, we can do the following.

(5/6) * 180 = 150

So, Lucy got 150 votes.

Answer:

150

Step-by-step explanation:

We can first divide 180 by 6:

180/6 = 30

Then multiply that by 5:

5 × 30 = 150

Answer:

For example, if you have to work out the original price of a laptop that is being sold at 25% off:

work out the current price as a percentage of the original price (100%): current price is 100% - 25%

Find 1% by dividing the current price by 75.

Multiply this 1% by 100 to find the original price (100%)

Step-by-step explanation:

Answer:

$42.25

Step-by-step explanation:

List price = $65.00

Discount = 35% .

Hence the new price is (100-35)% = 65% of original price .

=> price = $ 65 * 65/100

=> price = $42.25

The net pay is the amount left after taxes and deductions have been removed from the gross pay.

Her monthly gross pay is: $4111.93

The deductions are:

[tex]\mathbf{FIT = \$102}[/tex]

[tex]\mathbf{SIT = 3.2\%}[/tex]

[tex]\mathbf{CIT = 1.8\%}[/tex]

Let her gross pay be x.

So, we have:

[tex]\mathbf{Net = x - FIT - x \times SIT - x \times CIT}[/tex]

So, we have:

[tex]\mathbf{3804.33 = x - 102 - x \times 3.2\%- x \times 1.8\%}[/tex]

Express percentage as decimals

[tex]\mathbf{3804.33 = x - 102 - x \times 0.032- x \times 0.018}[/tex]

[tex]\mathbf{3804.33 = x - 102 - 0.032x - 0.018x}[/tex]

Add 102 to both sides

[tex]\mathbf{3906.33 = x - 0.032x - 0.018x}[/tex]

[tex]\mathbf{3906.33 = 0.95x}[/tex]

Divide both sides by 0.95

[tex]\mathbf{4111.93 = x}[/tex]

Rewrite as:

[tex]\mathbf{x = 4111.93 }[/tex]

Hence, her monthly gross pay is: $4111.93

Answer:

(a+2)(a+6)

Step-by-step explanation:

Given expression ,

=> a² + 8a + 12

=> a² + 6a + 2a + 12

=> a(a+6) + 2(a+6)

=> (a+2)(a+6)

By def. of the derivative, we have for y = ln(x),

[tex]\displaystyle \frac{dy}{dx} = \lim_{h\to0} \frac{\ln(x+h)-\ln(x)}{h}[/tex]

[tex]\displaystyle \frac{dy}{dx} = \lim_{h\to0} \frac1h \ln\left(\frac{x+h}{x}\right)[/tex]

[tex]\displaystyle \frac{dy}{dx} = \lim_{h\to0} \ln\left(1+\frac hx\right)^{\frac1h}[/tex]

Substitute y = h/x, so that as h approaches 0, so does y. We then rewrite the limit as

[tex]\displaystyle \frac{dy}{dx} = \lim_{y\to0} \ln\left(1+y\right)^{\frac1{xy}}[/tex]

[tex]\displaystyle \frac{dy}{dx} = \frac1x \lim_{y\to0} \ln\left(1+y\right)^{\frac1y}[/tex]

Recall that the constant e is defined by the limit,

[tex]\displaystyle e = \lim_{y\to0} \left(1+y\right)^{\frac1y}[/tex]

Then in our limit, we end up with

[tex]\displaystyle \frac{dy}{dx} = \frac1x \ln(e) = \boxed{\frac1x}[/tex]

Answer:

y = 1/3x + 6

Step-by-step explanation:

Format the given line into slope-intercept form:

y = -3x + 5

Perpendicular lines have a reversed sign and reciprocal slope:

y = 1/3x + b

Plug in the points:

3 = (-9) * 1/3 + b

3 = -3 + b

b = 6

Plug in b:

y = 1/3x + 6
