Answer:

-6 a b + b + a

Step-by-step explanation:

Simplify the following:

-(a - b + a b) - a b - 4 a b + 2 b - 2 b + 3 a - a

Hint: | Group like terms in 3 a - 2 b - a b - (a b - b + a) - 4 a b + 2 b - a.

Grouping like terms, 3 a - 2 b - a b - (a b - b + a) - 4 a b + 2 b - a = -(a b - b + a) + (-a b - 4 a b) + (3 a - a) + (2 b - 2 b):

-(a b - b + a) + (-a b - 4 a b) + (3 a - a) + (2 b - 2 b)

Hint: | Combine like terms in -a b - 4 a b.

a b (-1) + a b (-4) = -5 a b:

-(a b - b + a) + -5 a b + (3 a - a) + (2 b - 2 b)

Hint: | Combine like terms in 3 a - a.

3 a - a = 2 a:

-(a b - b + a) - 5 a b + 2 a + (2 b - 2 b)

Hint: | Look for the difference of two identical terms.

2 b - 2 b = 0:

-(a b - b + a) - 5 a b + 2 a

Hint: | Distribute -1 over a b - b + a.

-(a b - b + a) = -a b + b - a:

-a b + b - a - 5 a b + 2 a

Hint: | Group like terms in -a b - 5 a b + b + 2 a - a.

Grouping like terms, -a b - 5 a b + b + 2 a - a = (-a b - 5 a b) + b + (-a + 2 a):

(-a b - 5 a b) + b + (-a + 2 a)

Hint: | Combine like terms in -a b - 5 a b.

a b (-1) + a b (-5) = -6 a b:

-6 a b + b + (2 a - a)

Hint: | Combine like terms in 2 a - a.

2 a - a = a:

Answer: -6 a b + b + a

Answer:

A. f(x) = (one-half) Superscript x  

D. The domains of both functions are the same.

E. The translation from f(x) to g(x) is right 4 units and down 2 units.

The answers are A, D, and E

Step-by-step explanation:

Edge 2020

The statements about the functions are true A. [tex]f(x) = (1/2)^x[/tex]

D. The domains of both functions are the same.

E. The translation from f(x) to g(x) is right 4 units and down 2 units.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).

We are given that On a coordinate plane, 2 exponential functions are shown. f (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1.

When evaluated in zero we have:

f(0) = 2(1/2)^0 = 2

So it crosses through the point (0, 2).

And when evaluated in x = 1, then

f(1) = 2(1/2)^1 = 1

Then it also passes through (1, 1).  It goes crosses the y-axis at (0, 14) and goes through (1, 5) and (2, 2).

The answers are A, D, and E

Answer:

1. 0.4

2. 2.5

Step-by-step explanation:

Answer:

CD = 15

x = 5

Step-by-step explanation:

Since BF ≅ FD and AE ≅ EC, then [tex]EF = \frac{AB + CD}{2}[/tex]

So, [tex]30 = \frac{x^{2} +20 + x^{2} + 22x - 120}{2}[/tex]

[tex]60 = 2x^{2} + 22x - 100[/tex]

[tex]2x^{2} + 22x - 160 = 0[/tex]

[tex]2(x^{2} + 11x - 80) = 0[/tex]

2(x - 5)(x + 16) = 0

x = 5  or x = -16

If x = 5, then CD = [tex]5^{2} +22(5) - 120 = 25 + 110 - 120 = 15[/tex]  

Ix x = -16, then CD = will be a negative number which it cannot be.

Answer:

180%

Step-by-step explanation:

well 1 = 100%.

4/5 can get up to 100 if you multiply by 20/20. so 4/5 x 20/20 is 80/100 or 80%

100% + 80% is 180%

Answer:

7.45645 miles

Step-by-step explanation:

12 divided by 1.609 equals 7.45645

You divide 12 kilometers by to get miles.

Jordan has to race 7.45645 miles.

The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

Given:

Jordan wants to run a 12-kilometer race.

We know 1 Km= 0.621371 miles

So, To convert 12 Km into miles

12 Km = 12 x 0.621371

            = 7.45645 miles

Hence, Jordan has to race 7.45645 miles.

Answer AND expaination

The product of a number and 3 increased by 5 is 7 less than twice the number which equation can be used to find this number , n?

its -7

the product of a number and 3: 3n

increased by 5: + 5

7 less than: - 7

twice the number: 2n

That gives us the following:

3n + 5 = 2n - 7

You only asked for the equation, not to actually help you solve for n, for note. If you do, just subtract 2n from both sides, and then subtract 5 from both sides.

Answer:

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

         A2 - AB + BA - B2 =

         A2 - AB + AB - B2 =

         A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 16 is the square of 4

Check :  x4  is the square of  x2 

Factorization is :       (x2 + 4)  •  (x2 - 4) 

Equivalent expressions are expressions with equal values

The equivalent expression of [tex]\mathbf{x^6 - 16x^2}[/tex] is [tex]\mathbf{x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]

The expression is given as:

[tex]\mathbf{x^6 - 16x^2}[/tex]

Factor out x^2

[tex]\mathbf{x^6 - 16x^2 = x^2(x^4 - 16)}[/tex]

Express x^4 as (x^2)^2

[tex]\mathbf{x^6 - 16x^2 = x^2((x^2)^2 - 16)}[/tex]

Express 16 as 4^2

[tex]\mathbf{x^6 - 16x^2 = x^2((x^2)^2 - 4^2)}[/tex]

Apply difference of two squares

[tex]\mathbf{x^6 - 16x^2 = x^2((x^2 - 4)(x^2 + 4))}[/tex]

Express 4 as 2^2

[tex]\mathbf{x^6 - 16x^2 = x^2((x^2 - 2^2)(x^2 + 4))}[/tex]

Apply difference of two squares

[tex]\mathbf{x^6 - 16x^2 = x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]

Hence, the equivalent expression of [tex]\mathbf{x^6 - 16x^2}[/tex] is [tex]\mathbf{x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]

Answer:

where is the Triangle below

Answer:

The area of a rectangle is l x w. So the area of the square is 10 x 10 = 100

The area of a circle is

[tex]\pi \times {r}^{2} [/tex]

The radius of all the circles is 2 inches.

[tex]\pi \times {2}^{2} = \pi \times 4 \: or \: 4\pi[/tex]

There are 4 circles so the area of all four is

[tex]4 \times (4\pi) \: or \: 16\pi[/tex]

To find the area of the shaded part of the square, subtract the area of all the circles, because they are not shaded, from the area of the square, because it is shaded. The difference will be the area of the shaded portion.

[tex]area \: = 100 - 16\pi[/tex]

[tex]area = 100 - 50.6548[/tex]

So the area is approximately 50 Sq in
