Answer:

c = 9

Step-by-step explanation:

You're looking for a number so that when you use that number in place of x, you end up with 20.

f(x) = 3x - 7

f(c) = 3c - 7

20 = 3c - 7

Add 7

27 = 3c

Divide by 3

9 = c

Step-by-step explanation:

From the image, I'm pretty sure it's asking you to find where the line can be "cut" into to make it symmetrical. If this is true, you would need to find a half way mark in the graph, or try and plot this on the graph.

Answer:

B

Step-by-step explanation:

The true statements are m + 2.1 > n + 2.1, m - (-4) > n - (-4) and 9 + m > 6 + n

The inequality is given as:

m > n

When the same constant k is added to both sides of the inequality, we have:

m + k > n + k

This means that the following inequality is true

m + 2.1 > n + 2.1

When the same constant k is subtracted from both sides of the inequality, we have:

m - k > n - k

This means that the following inequality is true

m - (-4) > n - (-4)

Also, if a greater constant is added to m, then the inequality still remains the same.

This means that the following inequality is true

9 + m > 6 + n

Hence, the true statements are m + 2.1 > n + 2.1, m - (-4) > n - (-4) and 9 + m > 6 + n

Answer:

5x5x5x5

Step-by-step explanation:

The expression that has the same value as [tex]5^4[/tex] is 25² or 625.

Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner.

We have [tex]5^4[/tex].

Usually exponents can be expand using the number the power is raised.

As, if we have 9³ then it means 9 is multiplies by itself three times.

So, 9³ = 9 x 9 x 9= 729

Now, we have to expand  [tex]5^4[/tex] as

= 5 x 5 x 5 x 5

= 5² x 5²

= 25 x 25

= 25²

= 625

So, the Equivalent value to  [tex]5^4[/tex] is 25² or or 5² x 5² or 625.

Answer:

1st Statement: False

2nd Statement: True

3rd Statement: True

4th Statement: False

Answer:

False

True

False

True

Step-by-step explanation:

Whole numbers are 'counting numbers', they don't include decimals. (ex. 1, 2, 3) Integers are non-decimal numbers and they can be negative too. (ex. -5, 0, 4). Since whole numbers are non-decimal numbers that are greater than or equal to 1, they are all integers. So this statement is False.

Rationals numbers include all numbers that are not infinite decimals. They can be fractions as long as they are not infinite and since whole numbers cannot be fractions, this statement is True.

As with the previous statement, rational numbers can be fractions and integers cannot be fractions. So, not all rational numbers are integers so this statement is False.

Rational numbers are all numbers that are not infinite decimals, so, that includes whole numbers. This statement is also True.

There are a couple of different ways we can do this: change the fraction into a decimal or multiply by the reciprocal.

Change the Fraction Into a Decimal

---3/4 = 0.75

So, instead of using the fraction, we can put it into decimal form. We will need to move the decimal point in both numbers though, making our division problem as follows:

20096 / 75 = ?

---The decimal point was moved two places to the right in order to make the former fraction a whole number.

Multiply by the Reciprocal

---To find the reciprocal, switch the numerator and denominator, essentially "flipping" the fraction upside down.

Another way of dividing by fractions is multiplying by the reciprocal. For example, dividing a number by 3 is the same thing as multiplying by 1/3. We can do the same in this problem. Instead of dividing by 3/4, we can multiply by 4/3, making our problem look as follows:

200.96/1 x 4/3 = ?

Answer: 803.84 / 3 = 267.9467

If the sin θ is equal to the negative one then the value of the θ will be 3π / 2. Then the correct option is C.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

A unit circle is shown.

A radius with length 1 forms angle θ in the first quadrant.

Then the sin θ is equal to the negative one. Then the value of the θ will be

sin θ = -1

Then it can be written as

θ = sin⁻¹ (-1)

θ = 3π / 2

Thus, the correct option is C.

Answer: 35, 35, 70, and 220

Step-by-step explanation:

– Let x = size of one of the two equal angles

The sum of angles in a quadrilateral is 360:

360 = x+ x + ( x+x ) x (2( x+ x+ x+x ) – 60)

360 = 4 + 2(4 ) – 60

360 = 4 + 8 – 60

360 = 12 – 60

12x = 420

= 35

Substituting x for 35, will get: 35, 35, 70, 220

The values of the angles are 35°, 35°, 70° and 220°
