Write the following expression as a simplified polynomial in standard form.
(x - 5)^2+3(x - 5) - 4

Answer:

The domain of y = cos θ is all real numbers. This is because any real number can be plugged in for θ and y will be equal to a real number. This can be shown graphically because the y = cos θ will go on infinitely both to the right and left.

Answer:

Step-by-step explanation:

Positive rational numbers will be in the right side of the number line.

Negative rational numbers will be in the right side of the number line.

18.256 will be lying in between 18.25 and 18.26

Answer:

45 degrees

Step-by-step explanation:

Hi there!

We're given that one of the triangle's exterior angles is 90 degrees. Using that, we can solve for the corresponding interior angle by subtracting 90 from 180 degrees:

180-90 = 90

Given that the two legs of this right triangle are of equal length, we know that the remaining two angles both measure x. Knowing that the sum of the interior angles in a triangle is 180 degrees, we can set up an equation:

x+x+90=180

2x=90

x=45

Therefore, x is 45 degrees.

In fact, any right triangle with legs of equal length will be a 45-45-90 triangle, meaning the other two angles measure 45 degrees.

I hope this helps!

Answer:

Sides = 8 each and base = 6

Step-by-step explanation:

Let congruent legs = x, then the base is x - 2 so,

P = x + x + (x - 2)

22 = 3x - 2

24 = 3x

8 = x (sides)

base = 8 - 2 = 6

Answer:

x = 5

Step-by-step explanation:

Sum of angles = 180, so

60 + 80 + 8x = 180

140 + 8x = 180

8x = 180 - 140 = 40

x = 40/8 = 5

Answer:

A&C

Step-by-step explanation:

They are negative and even and they are not positive and even too.

Answer:

A

Step-by-step explanation:

Technically A and C are correct but we are dealing with only negative even values. A non-positive integer is any negative number or zero but we don't have that value so it makes more sense to choose A than C. B is incorrect because a whole number can't include a negative number, a fraction, or a decimal. D is also incorrect because a non-negative integer is a positive number which we don't have in the set.

Best of Luck!

Answer:

95kg

Step-by-step explanation:

Mass÷Volume=Density

Therefore, Mass = Volume × Density

Mass = 1500 × 95

Mass = 95,000g

Since we were asked to find the mass in kg:

1000g = 1kg

Therefore, 95,000g = 95kg

Answer:

[tex]x = 15x[/tex]

Step-by-step explanation:

[tex] \frac{5}{12} = \frac{x}{36} [/tex]

[tex] \frac{5 \times 36}{12 } = x[/tex]

[tex]5 \times 36 = 12x[/tex]

[tex]180 = 12x[/tex]

[tex]12x = 180[/tex]

[tex]12x \div 12 = 180 \div 12[/tex]

[tex]x = 180 \div 12[/tex]

[tex]x = 15[/tex]

Step-by-step explanation:

lines that are parallel have the same gradient. So the gradient is 4/5

Lines that are perpendicular have "opposite reciprocal" gradient: flip the sign, then flip the numerator and denominator (top/bottom). So the gradient  is -3/4

Answer:

a)=10m

b)(x+1)

c)=(27x+9)

d=(3x+1)

Answer:

x = 11

Step-by-step explanation:

These angles are alternate exterior angles which means they are equal to each other:

5x + 9 = 6x - 2

5x - 6x = -2 - 9

-x = -11

x = 11

Answer:

check explanation

Step-by-step explanation:

in eqn 2,

y = 3 - 2x

substitute for it in eqn 1

3x² + y² = 20

3x² + (3 - 2x)² = 20

3x² + 9 - 12x + 4x² = 20

Group like terms;

3x² + 4x² - 12x = 20 -9

7x² - 12x = 11

x(7x - 12) = 11

x = 11,

OR

7x - 12 = 11

7x = 11 + 12

7x = 23

x = 23/7

x = 3.286

To get y, substitute for x in eqn 2

WHEN x = 11,

y = 3 - 2(11)

y = 3 - 22

y = -19

WHEN x = 3.286

y = 3 - 2(3.386)

y = -3.772

Answer:

B irrational :]..............

Answer:

the mistake is that to "remove" the 1/2 on the left you would have to multiply by 2 (or divide by 1/2 but no one does that)

the result would be that 2h-4 = 10  should actually be 2h-4 = 20

Step-by-step explanation:

Answer: $864.63

Step-by-step explanation:

First find the original price. Write 20% as the decimal 0.20 before using it in the equation.

price

= cost+mark-up

= 960.70+0.20×960.70

= 960.70+192.14

= 1,152.84

The original price was $1,152.84.

Now find the discount price. Write 25% as the decimal 0.25 before using it in the equation.

discount price

= original price–discount

= 1,152.84–0.25×1,152.84

= 1,152.84–288.21

= 864.63

The discount price was $864.63.

Answer:

WHAT

Step-by-step explanation:

Answer:

-$45

Step-by-step explanation:

Find how much he owes his friends in total by multiplying 3 by 15:

3(15)

= 45

So, he owes his friends $45.

Since he has no money, we can find his worth by subtracting 45 from 0:

0 - 45

= -45

His worth is -$45.

Answer:

x = 4

Step-by-step explanation:

Vertical angles are equal.

m∠1 = m∠2

10x - 9 = 4x + 15

Add 9 to both sides

10x = 4x + 15 + 9

10x = 4x + 24

Subtract 4x from both sides

10x -4x = 24

6x = 24

Divide both sides by 6

x = 24/6

x = 4

Answer:

t ≥ 0.2c

Step-by-step explanation:

Her tip is at least 20% of the cost of the meal, so her tip is greater than or equal to 20% of the cost of the meal

tip ≥ 20% of the cost of the meal

t ≥ 20% of c

Another way of writing "20% of c" is multiplying the two values, so we have

20% of c = 20% * c

t ≥ 20% * c

To convert from a percentage to a decimal, we can divide the percentage by 100. Here, we have

20% = 0.2

t ≥ 0.2 * c
