Find the lowest common multiple (LCM) of 30 and 42

Answer:

f(10) = 8

Step-by-step explanation:

f(x) = 4(x - 8)

Let x = 10

f(10) = 4 ( 10-8)

       = 4 ( 2)

      = 8

Here, we are provided with a polynomial in x and it's general value in variable X is also given.

[tex]f(x) = 4( x - 8)[/tex]

We need to find the value of f(10)

For this, we need to substitute the value of x with 10, because we are required to find f(10)

Given polynomial, f(x) = 4(x - 8), Putting value of x

[tex]f(10) = 4(10 - 8)[/tex]

[tex]f(10) = 4(2)[/tex]

[tex]f(10) = \boxed{ \red{8}}[/tex]

This is our required answer !!

Answer:

a=2

Step-by-step explanation:

You can have "a" on both sides and still get an answer easily. You start off by adding 8a to the right. That makes 8+4a=16. You then subtract 8 from 16 and get 4a=8. Divide by 4 to get your answer. You get a=2

Answer:

She needs to measure the length of the diagonal and two sides of the frame. Then she needs to find the square of each measure. If the sum of the squares of the two smaller sides equals the square of the diagonal, then she created a right triangle.

Answer:

There are 40 multiples of 5.

Step-by-step explanation:

You take 10000 and subtract 8000 = 2000.

Then divide 2000 by 5.

Answer:

you can't add or subtract numbers that don't have the same variable or the same exponent

Answer:

You cannot combine the terms [tex]8a^2[/tex] and [tex]8a[/tex] because they are not like terms, which are terms that consist of both the same power, and the same variable. Seen with the two terms given, they both share the same variable ([tex]a[/tex]), but not the same power ([tex]2[/tex]).

Answer:

Step-by-step explanation:

step one:

Given that the scale of the map is

 2cm to represent 30 miles

That is  every 1 cm is 15 miles in reality

step one:

what we are solving for is the distance in cm on the map so,

1cm rep 15miles

xcm rep 75miles

cross multiply

Xcm= 75/15

X= 5 cm

hence on the map 75miles distance between the two towns is seen as 5 cm

Steps to solve:

185 = -5(10r + 3)

~Distribute right side

185 = -50r - 15

~Add 15 to both sides

200 = -50r

~Divide -50 to both sides

-4 = r

Best of Luck!

Answer:

r=-4

Step-by-step explanation:

185= - 5 10 r + 3

37= 10 r + 3

10r = - 3 - 37

10 r = - 40

Answer:

the answer is A

Step-by-step explanation:

subtract 4 in both sides

Answer:

X= -14

Step-by-step explanation:

Answer:

B. Between Step 1 and Step 2, combining like terms is used.

Answer:-29/3

combine like terms: -3x=29

divide by -3 on both sides: x= -29/3

Answer:

(-2.5, -3.5)

Step-by-step explanation:

In order to find midpoint, you must add both x coordinates then divide by two and add both y coordinates then divide by two.

1 + (-6) = -5

-5/2 = -2.5

1 + (-8) = -7

-7/2 = -3.5

Answer:

The variable y = 2.100

Step-by-step explanation:

Here, we are told to solve for the variable y.

We are asked to use the segment addition postulate. In summary, the postulate is of the opinion that given 3 points X,Y and Z, we can only say that these 3 points are collinear(lie on the same line) if they obey the formula below;

XZ = XY + YZ

Now, we have that S is between R and T.

Mathematically that means;

RT = RS + ST

from the question, we are told that RT = 26, RS = 9y-2 and ST = y + 7

Now, insert these values into the alphabetical equation;

26 = (9y-2) + (y + 7)

26 = 9y-2 + y + 7

26 = 9y+y -2 + 7

26 = 10y + 5

26-5 = 10y

10y = 21

y = 21/10

y = 2.1

Which is y = 2.100 to three decimal places

Answer:

Step-by-step explanation:

If the profit of a company made by the company is in the form a quadratic expressions but in the different forms as given in the question.

a). The prices that give a profit of zero dollars.

    Expression that is most useful,

    Factored form: -2(p - 3)(p - 9) = 0

    p = 3, 9

b). The profit when the price is zero .

    Standard form:

    Profit = -2p² + 24p - 54 = 0

    -p² + 12p - 27 = 0

    -p² + 3p + 9p - 27 = 0

    -p(p - 3) + 9(p -3) = 0

     (-p + 9)(p - 3) = 0

     p = 3, 9

c). The price that gives the maximum profit.

   Vertex form: -2(p - 6)² + 18

   Vertex of the given expression → (6, 18)

   Maximum profit will be at p = 6.

   Therefore, profit = -2(6 - 6)² + 18 = 18

Answer:

27.7

Step-by-step explanation:

For this problem, we will simply use standard rounding conventions to round the number to the nearest tenth.

If the number after the target, the hundreths place in this case, is between 0 and 4, we won't change the tenths place.  If the number is between 5 and 9, we will increment the tenths place by one.

So for our number, 27.68, 8 is between 5 and 9 so we will increment the tenths place by one for the round.

Hence, our rounded answer for the nearest tenth is 27.7.

Cheers.
