The line that contains the point Q( 1, -2) and is parallel to the line whose equation is y - 4 = 2/3 (x - 3)
Musya8 [376]

Answer:

y + 2 = \frac{2}{3}(x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 4 = \frac{2}{3}(x - 3) ← is in point- slope form

with slope m = \frac{2}{3}

Parallel lines have equal slopes, thus equation of parallel line

with m = \frac{2}{3} and (a, b) = Q(1, - 2) is

y - (- 2) = \frac{2}{3}(x - 1) , that is

y + 2 = \frac{2}{3}(x - 1)

Which of these inequalities means that<br> 18 is greater than three times a number?
AnnyKZ [126]
<h3>hello!</h3>

Let's write this verbal phrase as an inequality.

First of all, let the number be n.

"three times n" can be written like so:-

\pmb{3n}

Now, 18 is greater than 3n:-

\pmb{18 > 3n}

Which means 3n is less than 18:-

\bigstar{\boxed{\pmb{3n < 18}}}

<h3>note:-</h3>

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I'll comment and/or edit my answer :)

All Food City oranges are normally $3 per pound, but this week they are on sale for $2 per
stepladder [879]

Answer:

33.33%

Step-by-step explanation:

The oranges have decreased by one dollar per pound so you have to find the percentage of 3 that is 1. To do this is 1 over 3 multiplied by 100%

= \frac{1}{3} \\ * 100%

And this will give you 33.33%

Identify the function family that each belongs to: a. linear b. exponential c. quadratic d. linear absolute value f(x)=x+2 f(x)=
Dmitriy789 [7]

The function family that each belongs to are :

a. linear = f(x)=x+2

b. exponential = f(x)=2^x

c. quadratic = f(x)=x^2

d. linear absolute value = f(x)=|2x|

A linear function should have either one or more variables without exponential form

A quadratic function should have either one or more variables with exponential form with degree 2

An exponential function has a variable raised to the power constant

A linear absolute contains a absolute value expression
