Write a word phrase to represent the numerical expression below.<br><br> 5+(17-8)

Klio2033 [76]

Answer:

Step-by-step explanation:

So ,to create a word phrase, you have to identify all of the operations going on here...

5+(17 - 8)

within the parentheses, you have subtraction. that's usually called the "difference" in word phrases. you also have a 5 outside the parentheses, leaving it to be multiplied inside, and multiplication is typically referred to as a "product"

with that info, you can construct a word phrase such as "the product of 5 and the difference between 17 and 8" or "the difference between 17 and 8 multiplied by 5"

Given:

Line a passes through (2, 10) and (4, 13).

Line b passes through (4, 9) and (6, 12).

Line c passes through (2, 10) and (4, 9).

To find:

Which of the lines, if any are perpendicular.

Solution:

If a line passes through two points, then the slope of line is

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Line a passes through (2, 10) and (4, 13). So, slope of this line is

$m_a=\dfrac{13-10}{4-2}=\dfrac{3}{2}$

Line b passes through (4, 9) and (6, 12). So, slope of this line is

$m_b=\dfrac{12-9}{6-4}=\dfrac{3}{2}$

Line c passes through (2, 10) and (4,9). So, slope of this line is

$m_c=\dfrac{9-10}{4-2}=\dfrac{-1}{2}$

Product of slopes of to perpendicular lines is -1.

$m_a\cdot m_b=\dfrac{3}{2}\times \dfrac{3}{2}=\dfrac{9}{4}\neq -1$

$m_b\cdot m_c=\dfrac{3}{2}\times \dfrac{-1}{2}=\dfrac{-3}{4}\neq -1$

$m_a\cdot m_c=\dfrac{3}{2}\times \dfrac{-1}{2}=\dfrac{-3}{4}\neq -1$

Therefore, any of these lines are not perpendicular to each other.

There are four cards numbered 1 through 4. The number 2 card is chosen randomly and not replaced. Find the probability of choosi

malfutka [58]

Answer:

1/3

Step-by-step explanation:

since number 2 card was not replaced, we have;

probability of picking a second card, 3;

let S be number of sample space

n(S)= 4

n(3)= 1

Pr(3/2)= 1/3

(because since one was already chosen and n, the sample space would reduce)

Find the value of x 55+(x+25)=180

s344n2d4d5 [400]

55+(x+25)=180
55+x+25=180
25+55+x=180
80+x=180
x=180-80
x=100

A cell phone plan charges $39.95 a month plus 15 cents per text message sent and 15 cents per text message received. Using s to

Allisa [31]

Answer:

c= 39.95 +0.15 (s + r) (take the 63 received and plug it in for r and 53.45 in for c then solve)

53.45= 39.95 +0.15 (s +63) (use the distributive property)

53.45 = 39.95 + 0.15s + 9.45 (combine like terms on the right side)

53.45 = 49.40 +0.15s (subtract 49.40 from both sides)

4.05 = 0.15s (divide both sides by 0.15 so isolate s)

s= 27 (how many text messages were sent)

Step-by-step explanation:

I hope this helps :)
