Answer:

18x - x^2 - 16

Step-by-step explanation:

10x - ((x - 4) (x - 4))

10x - (x - 4)^2

10x - (x^2 - 2x · 4 + 4^2)

10x - x^2 + 2x · 4 - 4^2

10x - x^2 + 8x - 16

(10x + 8x) - x^2 - 16

Answer:

11

Step-by-step explanation:

The number 11 is called the base, while the number 12 is called the exponent .

Answer:

11

Step-by-step explanation:

An exponential has the base at the bottom, or the lower portion. Think of "basement" to help remember this. The exponent is the number up top, so 12 is the exponent.

Elevation of the plane is y.

y =

The airplane starts at an elevation of 8500 feet

y = 8500

It is said that the plane loses elevation at a rate of 150 feet per minute.

y = 8500 - 150

We don't know how many minutes the plane has been losing elevation so we use m

y = 8500 - 150m

Answer:

Answer:

  |h -1.7| ≤ 0.5

Step-by-step explanation:

Consider the absolute value inequality ...

  |x -a| ≤ b

This is fully equivalent to ...

  -b ≤ x -a ≤ b

because the value between the absolute value bars can be either positive or negative. If we add a to this, we get ...

  -b +a ≤ x b +a

__

Comparing this to your given expression, we find ...

  -b +a = 1.2

  b + a = 2.2

If we add these equations together, we get ...

  0 +2a = 3.4

  a = 1.7 . . . . . . . the midpoint of the interval [1.2, 2.2]

  b = 2.2 -a = 0.5 . . . . half the width of the interval [1.2, 2.2]

So, your absolute value inequality is ...

  |h -1.7| ≤ 0.5

Answer:

8

Step-by-step explanation:

Since you can divide 4 into 8 evenly, it's the larger of the two - the lowest common denominator is 8.

The least common denominator of the fractions will be 4.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of a numerator and a denominator.

The least common denominator of the fractions:

7/8 and 1/4

Take 4 common from the denominator of both the fraction numbers 7/8 and 1/4. Then the number will be

7/2 and 1

The least common denominator of the fractions will be 4.

Answer:

The correct option is;

Step function

Step-by-step explanation:

The given information are;

The cost of mailing a letter for the first ounce= $0.37

The cost for each additional ounce = $0.23

Therefore, the cost of mailing a letter can be found from the relation;

y = (N-1) × $0.23 + $0.37

The step function can be represented as follows;

f(x) = a[b(x - h)] + k

Where;

(h. k) = The starting points

a = The vertical step separation

b = The horizontal step separation

Therefore, in the question, we have;

a = $0.23

b  = 1

h = 1

k = $0.37

Which gives;

f(x) = $0.23 × [1(x - 1)] + $0.37 = $0.23 × (x - 1) + $0.37

f(x) = $0.23 × (x - 1) + $0.37 which is similar to y = (N-1) × $0.23 + $0.37

Therefore the function that models the situation is step function.

ABCB AGHBGHCGHDGH

90°  90°

45°  45°

135°  135°

90°  90°

Step-by-step explanation:

The measure of each angle of the reflected polygon is same as the corresponding angle of the original one.

By reflection about a line, the polygon changes its position such that the distance of every point from the original one will be the same as the distance from every corresponding point of the reflected one from that line.

So according to the question,

Let polygon ABCD is reflected about line GH then the reflected polygon will be A'B'C'D'

Let ∠ABC= 120°

∠BCD= 80°

∠CDA= 70°

∠DAC= 90°

Now if we measure the corresponding angle of the reflected polygon A'B'C'D', then the reflected corresponding angle will be

∠A'B'C'= 120°

∠B'C'D'= 80°

∠C'D'A'= 70°

∠D'A'C'= 90°

Therefore the measure of each angle of the reflected polygon is the same as the corresponding angle of the original one.

Answer:

Peter hit 12 home runs and alice hit 6 home runs

Step-by-step explanation:

this is right because if Peter hit 6 and then he hit twice the amount that would bring his total to 12 due to 6 x 2 = 12 and if together they hit 18 home runs that would mean you want to subtract the total from Peter's and that would be explained as 18-12=6 and the 6 left over would leave you with alice number of home runs. Hope this helps :)

Answer:

21

Step-by-step explanation:

You must find a number that will divide into the total of the girls and boys and come up with an even number.  By looking at the numbers, you can see that both 56 and 91 will divide evenly by 7. The common denominator for both calculations is 7.

56/7=8 girls  

91/7= 13 boys

Add 8 girls and 13 boys and you will have 21 in each group.  That way, all groups are equally boys and girls.
