Answer:

15

Step-by-step explanation:

3+1+3+1+3+1+3= 15 this is what it would look like if you write it out. To save time do 3 times 4 to get 12 and then just add three ones to 12 to get 15.

Answer:

<em>y = (x - 4) - 4 </em>

Step-by-step explanation:

m = \frac{y_{2} - y_{1} }{x_{2} -x_{1} }

(- 2, - 10)

(4 , - 4)

m = \frac{-4+10}{4+2} = 1

y + 4 = (x - 4) ⇒ <em>y = (x - 4) - 4</em>

AlladinOne [14]

Answer:

Step-by-step explanation:

1 1/5 of 1 1/2 meters  

= (1+1/5) x (1+1/2)  

= 1x1 + 1x1/2 + 1x1/5 + 1/5*1/2  

= 1 + 1/2 + 1/5 + 1/10  

= 1 + (1x5+1x2+1)/10  

= 1 8/10  

= 1 4/5 meters

Write the equation of the line parallel to 5x + y = -2 that goes through the point (2, -3).​
gladu [14]

Answer:

y = -5x + 7

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Step 1: Define

5x + y = -2

Random point (2, -3)

Step 2: Rewrite

y = -5x - 2

m = -5

Step 3: Write parallel line

y = -5x + b

-3 = -5(2) + b

-3 = -10 + b

7 = b

y = -5x + 7

What are the domain and range of the function f(x) = 4? {x| x is a real number}; {y| y &gt; 0} {x| x &gt; 4}; {y| y &gt; 0} {x|
Crazy boy [7]

Answer:

The domain is {x:x is a real number}

The range is {y:y is only 4}

Step-by-step explanation:

The domain of the function is the values of x

The range of the function is the values of y

f(x) = 4 is represented graphically by a horizontal line // to x-axis from y = 4

Every point on the this line has different values of x but same value of y

ex: (-1 , 4)  , (5 , 4) , ( 0.1 , 4) , ................

So f(x) = 4 is called constant function
