Answer: x > 3

Step-by-step explanation:

We have the inequality:

-4*(2*x - 7) < 10 - 2*x

We want to find the possible values for x.

first, we expand the left side.

-8x + 28 < 10 - 2x

now we want to have all the terms with x in one side and the terms without x in the other side.

-8x + 2x < 10 - 28

-6x < -18

now we divide both sides by -6, as we divide by a negative number, the direction of the inequality changes:

x > 18/6 = 3

x > 3

This means that x must be larger than 3.

Answer:

a) 0

Step-by-step explanation:

Given that TRAP × 9 = PART and  T, R, A, P all have different integer values (that is their values are different). TRAP and PART are both made up of four integers digits, that means 1000 ≤ TRAP and PART ≤ 9999. This means that TRAP × 9 ≤ 10000. The value of R can be gotten from:

[tex]TRAP<\frac{10000}{9}<1112(rounding \ to \ the \ next \ whole \ number)[/tex]

T cannot be 0, therefore T= 1, Since their values are different, R cannot be equal to T, we get that R can only be 0

The answers are A and D. Hope this helps!

Answer:

Step-by-step explanation:

We have tanπ3=−tan2π3=tan4π3=3–√

Since tan(3x)=3tanx−tan3x1−3tan2x

Thus tanπ/9,−tan2π/9,tan4π/9are solutions to the polynomial 3–√=3x−x31−3x2

On simplication, x3−33–√x2−3x+3–√=0.(1)

Since (tanπ9−tan2π9+tan4π9)2

=tan2π9+tan22π9+tan24π9

+ 2( -tanπ9tan2π9+tanπ8tan4π9−tan2π9tan4π9)

By sum and product pairs of roots in (1) above

(−33–√)2=tan2π9+tan22π9+tan24π9+2×−3

∴tan2π9+tan22π9+tan24π9=33

Answer: 50 ft

Step-by-step explanation:

The correct function is h(t)=-16t^2+200t+50.

Hi, to answer this question we simply have to replace t =0 in the function given:

h(t)=-16t^2+200t+50.

h (0) = -16t^2+200t+50.

h(0) = 50

Step-by-step explanation:

Two same things can't equal different things.

Answer:

a). 8100 bacteria

b). 519 bacteria

c). Infinite

Step-by-step explanation:

Population growth of a bacteria is given by the exponential function,

f(x) = [tex]P_{0}(1+\frac{r}{100})^{t}[/tex]

Where f(x) = Population after time 't'

[tex]P_{0}[/tex] = Initial population

r = Growth rate

t = Duration after t hours

If "100 bacteria gets tripled every hour"

300 = [tex]100(1+\frac{r}{100})^{1}[/tex]

3 = 1 + [tex]\frac{r}{100}[/tex]

r = 100×(3 - 1)

r = 200

So the function is, f(x) = [tex]100(3)^{t}[/tex]

a). Population after 4 hours,

    f(4) = [tex]100(3)^{4}[/tex]

          = 8100 bacteria

b). Population after 90 minutes Or 1.5 hours

     f(1.5) = [tex]100(3)^{1.5}[/tex]

             = 519.61

             ≈ 519 bacteria

c). Population after 72 hours,

    f(72) = [tex]100(3)^{72}[/tex]

            = Infinite

Answer:

12a - 6b

Step-by-step explanation:

Given

8a + 3b + 4a - 9b ← collect like terms

= (8a + 4b) + (3b - 9b)

= 12a + (- 6b)

= 12a - 6b

Answer:

A I did the same quiz it’s A

Step-by-step explanation:

The correct option is "option A".

A function is graphed in the given figure.

We have to tell that which option is correct related to the graph.

What is a function ?

The function is the description of how the inputs relate to the output.  Each input has only one output.

According to the figure / graph ;

When x < 3

Then , y = [tex]x^{2}[/tex] + 6

Also , at , x = 3

We get an open interval.

So, we can say that ;

y = [tex]x^{2}[/tex] + 6 is valid for x < 3 not at x =3

Also , y = -x + 6 is valid for x ≥ 3 , here we get a close interval.

Thus , the correct option will be "option A" i.e.,

y = { x² + 6 , x < 3

and

y = { -x + 6 , x ≥ 3

g(f(2)+3) = g(3+3) = g(6)

g(6) = 6^2-6

Answer.

Step-by-step explanation: Whole numbers are written on cards and then placed in a bag. Pilar selects a single card, writes down the number, and then places it back in the bag. She repeats this 46 times.

Pilar calculates the relative frequency of each number card.

Outcome 1 2 3 4 5

Relative Frequency 0.05 0.35 0.26 0.13 0.21

Which statement about Pilar's experiment is true?

The outcomes do not appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Pilar's experiment.

Answer:

This is because when you multiply the fraction what you get is 60/30. This is equal to the number of 2. So the volume is 2.

5/3 * 3/2 * 4/5

= 5*3*4 = 15*4 = 60

= 3*2*5 = 6*5 = 30

Volume = 5/3 x 3/2 x 4/5

5/3 x 3/2 = 15/6

15/6 x 4/5 = 60/30 = 2

Volume = 2 cubic units

Answer:

532.86

Step-by-step explanation:

just subtract starting with the numbers after the decimal place

Answer:

In standard form: x - 2y = -10

In slope intercept form: y = (1/2)x + 5

Step-by-step explanation:

y = total cost

y = flat cost + mileage cost

The flat cost is $5, so you get

y = 5 + mileage cost

The mileage cost depends on the number of miles, x.

1 mile costs $0.50

2 miles cost $0.50 * 2

3 miles cost $0.50 * 3

x miles cost $0.50 * x, or simply 0.5x

Now we add the mileage cost to our expression.

y = 5 + 0.5x

y = 0.5x + 5

In standard form:

0.5x - y = -5

x - 2y = -10

In slope intercept form:

y = (1/2)x + 5

1. look at the first non-zero digit if rounding to one significant figure

2. look at the digit after the first non-zero digit if rounding to two significant figures

3.draw a vertical line after the place value digit that is required

4. look at the next digit

5.if it's 5 or more, increase the previous digit by one

6.if it's 4 or less, keep the previous digit the same

fill any spaces to the right of the line with zeros, stopping at the decimal point if there is one

Answer:

Step-by-step explanation:

Make the two function equal to eachother and then, bring -8 to the right which will be added with 20 to get 28. Now you left with 2x on the left side, divide both sides by 2 to solve for (x). Thus x= 14.

Answer and Step-by-step explanation:

To get this answer you need to understand what a function is, a function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. If this is false, this is NOT a function. So, knowing that, the correct answers are, All functions have a dependent variable, All functions have an independent variable, and A horizontal line is an example of a functional relationship. So this 1st, 2nd, and 5th options.
