# Jerry Don is here#

Answer 2

Answer:

[tex]\displaystyle [p + 2][p - 15][/tex]

Explanation:

Find two quantities that when differed to 13, they also multiply to 30. Those will be 2 and 15. The TINIER quantity gets the plus sign because the B-value is −13, therefore 15 gets the minus sign, leaving 2 with the plus sign.

What additional information would be sufficient, along with the given, to conclude that lmno is a parallelogram? check all that apply. ml ∥ no ml ⊥ lo lo ≅ mn ml ≅ lo mn ⊥ no

Answers

The conditions ML ║ NO and LO ≅ MN are sufficient to show that the LMNO is a parallelogram.

What is a parallelogram?

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a parallelogram, opposite sides are parallel and equal. And its diagonals are not equal but intersect at the mid-point.

The side ML is parallel to the NO that is given as

ML ║ NO

And the side LO is equal to the side MN

LO ≅ MN

These conditions are sufficient to show that the LMNO is a parallelogram.

What is the image of (x,y) after a translation of 3 units left and 7 units down?

Answers

Answer:

[tex](x + 3, y - 7)[/tex]

Step-by-step explanation:

Given

[tex]Function = (x,y)[/tex]

Translation:

[tex]Left = 3\ units[/tex]

[tex]Down = 7\ units[/tex]

Required

Determine the image of the function

Apply the first translation

[tex]Left = 3\ units[/tex]

When function (x,y) is 3 units translated left, we add the units to the x value.

The new function becomes:

[tex](x,y) -> (x + 3, y)[/tex]

Apply the second translation

[tex]Down = 7\ units[/tex]

We subtract 7 units from the y value

[tex](x,y) -> (x + 3, y)[/tex]

becomes:

[tex](x + 3, y) ->(x + 3, y - 7)[/tex]

Hence:

The image of the function is:

[tex](x + 3, y - 7)[/tex]

We should know that the angles in a triangle always add up to 180. We can subtract 75 and 30 from 180 giving us 75. Now we have 5k=75. Divide 75 by 5 and we have k which is 15. Hope this helps!

35. Priscila's age is k years while Mary's age is byears. If Mary is 15 years older than b Priscila, which of the following stateinents is correct? 2k + b = 15 -K= 15 6 K-6= 15 D. 20+k=15 A. В.​

Answers

The relationship between Priscilla's and Mary's age illustrates algebraic expression

The correct representation of the statements is b - k = 15

How to determine the representation of their ages?

From the question, we have:

Priscilla = k

Mary = b

Mary = 15 years older

The third highlight above means that:

Mary = 15 + k

Substitute b for Mary

b = 15 + k

Subtract k from both sides

b - k = 15

Hence, the correct representation of the statements is b - k = 15

The value of the logarithm expression [tex]log_{0.5}(16)[/tex] evaluated is given by : Option A: -4.00

What is logarithm and some of its useful properties?

When you raise a number with an exponent, there comes a result.

Lets say you get

[tex]a^b = c[/tex]

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

[tex]b = log_a(c)[/tex]

Some properties of logarithm are:

[tex]\log_a(b) = \log_a(c) \implies b = c\\\\\log_a(b) + \log_a(c) = \log_a(b \times c)\\\\\log_a(b) - \log_a(c) = \log_a(\frac{b}{c})\\\\\log_a(b^c) = c \times \log_a(b)\\\\\log_b(b) = 1\\\\\log_a(b) + log_b(c) = \log_a(c)\\[/tex]

Log with base e = 2.71828... is written as [tex]\ln(x)[/tex] simply.

Log with base 10 is written as [tex]\log(x)[/tex] simply.

For this case, we have to simplify the expression [tex]log_{0.5}(16)[/tex]

Let this is equal to 'a', then:

[tex]a = \log_{0.5}(16)\\\\0.5^a = 16\\(\dfrac{1}{2})^a = 16\\\\1^a/2^a = 2^4\\\\1 = 2^4 \times 2^a\\2^0 = 2^{4+a}\\\\0 = 4 + a\\a = -4[/tex]

(we used the property that: [tex]b^0 = 1[/tex] and [tex]k^m \times k^n = k^{m+n}[/tex] )

Thus, the value of the logarithm expression [tex]log_{0.5}(16)[/tex] evaluated is given by : Option A: -4.00

So,

∠NAB = ∠ABC + ∠BCA

105° = 57° + ∠BCA

Subtracting 57 to both sides

∠BCA = 105°-57°

20-29 all have a 2 in it meaning 30 is the only digit that doesnt have a 2 so 1/10 numbers

If one card taken from the bag then the probability that will not have the digit 2 on it is 1/11.

What is probability ?

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Given that,

Numbers from 20 to 30 are written on individual cards.

The total numbers of cards = 11

And numbers on cards = 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30

To find the probability of cards that have not the digit 2 on it.

Since, there is only one digit 30, which does not have digit 2,

Therefore, probability = favorable outcome / total outcome

= 1 / 11

The required probability of choosing a card that will not have the digit 2 on it is 1/11.

Answers

Answer:

X = 10

Step-by-step explanation:

Multiply both sides of the equation by 5

x + 2x - 60 = -30

Collect like terms

3x - 60 = -30

Move constant to the right-hand side and change its sign

3x = -30 + 60

Calculate the sum

3x = 30

Divide both sides of the equation by 3

x = 10

Solution

x = 10

Answer: x = 10

Step-by-step explanation:

1/5x + 2/5x - 12 = -6    Add 12 to both sides

1/5x + 2/5x = 6     Combine like terms on the left side
