fully simplify 7h² + 2h + 5 - h² + h​

Answer:

x^2 -4

Step-by-step explanation:

(x-2)(x+2)

We want to FOIL

First  x*x = x^2

Outer  x*2 =2x

Inner  -2 *x = -2x

Last  -2*2 = -4

Add them together

x^2+2x-2x-4

Combine like terms

The length of GX is 13 and the value of ∠ABX is 22.

We know that the point at which the triangle's three interior angle bisectors converge is known as the incenter. It can be thought of as the intersection of the triangle's internal angle bisectors. Due to the junction point of the central axis being the center of the triangle's inscribed circle, this point will be equally spaced from each of the triangle's sides. The center of a triangle's inscribed circle, which is the biggest circle that can fit inside the triangle, is known as the incenter.

Given that EX = 4z + 1 and  XF = 2z + 7.

Since X is the incentre of this triangle ΔABC, EX = XF = GX.

Now, 4z + 1 = 2z + 7

i.e. 4z - 2z = 7 - 1

i.e. 2z = 6

i.e. z = 6/2 = 3

Then GX = 2 * 3 + 7 = 6 + 7 = 13

Also given that ∠ABC = 44°.

Since X is the incentre of this triangle ΔABC, ∠ABX = ∠CBX

Let ∠ABX = ∠CBX = y

Now y + y = 44

i.e. 2y = 44

i.e y = 44/2 = 22

Then ∠ABX = 22°

Therefore, the length of GX is 13 and the value of ∠ABX is 22°.

The statement which correctly compares the two functions is that: A. they have the same y-intercept and the same end behavior as x approaches ∞.

A function is a mathematical expression which can be used to define and show the relationship that exist between two or more variables in a data set.

By critically observing the graph which models the function f (see attachment), we can logically deduce that the y-intercept is at four (4).

Also, from the table of function g (see attachment), we have:

At x = 0, g(x) = g(0) = 4.

In conclusion, the statement which correctly compares the two functions is that they have the same y-intercept and the same end behavior as x approaches infinity (∞).

The value of a in the exponential function is 4/5.

Given the exponential function is f(x)=a(3/2)ˣ.

An function may be a mathematical relation of the subsequent form: f(x)=aˣ. where x may be a variable, and a could be a constant called the exponential of the function.

When multiplying the any function by a constant, we may expand or shrink the function in the y-direction.

y=a(b)ˣ

If a>1 then the function will enlarge.

If a<1 then the function will shrink.

When a=4/5

Then 4/5<1 means the function would shrink.

When a=5/4

Then 5/4>1 means the function would enlarge.

When a=3/2

Then 3/2>1 means the function would enlarge.

When a=7/4

Then 7/4>1 means the function would enlarge.

Hence, the given function f(x)=a(3/2)ˣ would shrink when a=4/5.

Answer:

Step-by-step explanation:

got it right

Charlotte is 96 years old and Rachel is 292 years old

Let c represent Charlotte's age and r represents Rachels's age

From the question, we have:

c = r - 195

2 years later, we have:

r + 2 = 3(c + 2)

Expand the equation

r + 2 = 3c + 6

Subtract 2 from both sides

r = 3c + 4

Substitute r = 3c + 4 in c = r - 195

c = 3c + 4 - 195

Evaluate the like terms

-2c = -191

Divide by -2

c = 95.5

Approximate

c = 96

Substitute c = 96 in r = 3c + 4

r = 3*96 + 4

Evaluate

r = 292

Hence, Charlotte is 96 years old and Rachel is 292 years old

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

here m = - [tex]\frac{1}{5}[/tex] and c = 8 , then

y = - [tex]\frac{1}{5}[/tex] x + 8 ( multiply through by 5 to clear the fraction )

Answer:

Step-by-step explanation:

A rational number can be in the form of a whole/natural number, integers, fractions and recurring decimals

In this case, 5 is a whole number, integer (can be a fraction too) , and of course, is a rational number.

As of which options to choose, read the above sentence carefully :)

Answer:

Natural, Integer, Rational, Whole

Step-by-step explanation:

First, we should know the definition of the word choices.

1) Natural Numbers: We can also count it as 'counting numbers'. Natural numbers are numbers that are a whole excluding the number 0. Some examples are 1, 2, 3, 4, 5 ... and so on.

2) Irrationals: They are numbers that cannot be written in a fraction form. Some examples are [tex]\sqrt{2} , \sqrt{3} , \sqrt{4} , \pi ...[/tex] etc.

3) Integers: They are a whole number that can be a negative, positive, or even a zero. Natural numbers are included in integers. Examples are -2, -1, 0, 1, 2, and so on.

4) Rationals: They are numbers that can be expressed in a fraction form, so it is the opposite of 'irrationals'. Examples are -1/2, 1/2, 2/4, 2/1 ... etc.

5) Whole Numbers: They are numbers that aren't a fraction. It can only be a positive number and a zero, so some examples would be 0, 1, 2, 3, 4, 5 ... and so on.

With these in mind, we can now solve the question. The number 5 is a natural, integer, rational, and a whole number.

The tax paid by Rebecca on each cupcake was $0.15 or 15 cents, in the buying of 15 cupcakes for $47.25, where the cost of each was $3 plus taxes.

The tax is the amount paid to the government for buying and selling of goods are services.

In the question, we are informed that Rebecca bought 15 cupcakes, where each cupcake cost $3 plus taxes and the total bill to Rebecca was $47.25.

It implies that the cost of 15 cupcakes along with their taxes = $47.25.

Therefore, the cost of 1 cupcake along with its taxes = $47.25/15 = $3.15.

The cost of 1 cupcake is given as $3 plus taxes.

The total cost of 1 cupcake was $3.15.

Thus, the tax on 1 cupcake = $3.15 - $3 = $0.15 = 15 cents.

Thus, The tax paid by Rebecca on each cupcake was $0.15 or 15 cents, in the buying of 15 cupcakes for $47.25, where the cost of each was $3 plus taxes.

It looks like your equations are

7M - 2t = -30

5t - 12M = 115

Solving by substitution

Solve either equation for one variable. For example,

7M - 2t = -30   ⇒   t = (7M + 30)/2

Substitute this into the other equation and solve for M.

5 × (7M + 30)/2 - 12M = 115

5 (7M + 30) - 24M = 230

35M + 150 - 24M = 230

11M = 80

M = 80/11

Now solve for t.

t = (7 × (80/11) + 30)/2

t = (560/11 + 30)/2

t = (890/11)/2

t = 445/11

Solving by elimination

Multiply both equations by an appropriate factor to make the coefficients of one of the variables sum to zero. For example,

7M - 2t = -30   ⇒   -10t + 35M = -150 … (multiply by 5)

5t - 12M = 115   ⇒   10t - 24M = 230 … (multiply by 2)

Now combining the equations eliminates the t terms, and

(-10t + 35M) + (10t - 24M) = -150 + 230

11M = 80

M = 80/11

It follows that

7 × (80/11) - 2t = -30

560/11 - 2t = -30

2t = 890/11

t = 445/11

The measure in radians for the central angle of the circle is; 0.9 radians.

Since, the length of the arc is given as 7.2cm and it's radius is 8cm.

It follows that the angle measure of the central angle can be evaluated as follows;
