Answer:

Step-by-step explanation:

f(2) = 6        (what multiplies 2 to equal 6?)*2 = 6

It seems like x gets multiplied by three. Let's check the next one:

f(-1) = -3

Ah ha! We were right. Let's check one more time:

2 * 3 = 6

-1 * 3 = -3

f(x) just means what is f when x is any number. This function that we covered above is: f(x) = 3x

What are the coordinates of the midpoint of the segment whose endpoints are A(−1, −2) and B(6, 12) ? Enter your answer, as decim
maks197457 [2]

Answer:

(x,y)=\frac{5}{2},5  is the mid-point of given line segment.

Step-by-step explanation:

We have been given the coordinates of End points

To find the midpoint of the segment we will use mid point formula which is:

(x,y)=\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}

We have given x_1=-1,x_2=6,y_1=-2,y_2=12

Substituting the values in the formula we get:

(x,y)=\frac{-1+6}{2},\frac{-2+12}{2}

After simplification we get:

(x,y)=\frac{5}{2},5

I don't understand this question I'm supposed to be graphing
taurus [48]

y≤ 3 when x is 0  and x≤ 3 when y is 0

The graph is attached in figure below

Step-by-step explanation:

We need to graph x+y is equal or less than 3

Writing in mathematical form:

x+y\leq 3

For solving we find x and y intercepts

The y-intercept can be found by putting x=0, y is :

0+y \leq 3\\y\leq 3

y≤ 3 when x is 0

The x-intercept can be found by putting y=0, x is :

x+y \leq 3\\x+0\leq 3\\x\leq 3

x≤ 3 when y is 0

Plotting these values on the graph:

The graph is attached in figure below

Can i get some help on this question?
galben [10]

Answer:

a. 12.5

Step-by-step explanation:

Scale factor of ∆LMN to ∆XYZ = 2:5

To find length of side ZX, set the ratio of the corresponding sides of interest equal to the scale factor.

Thus:

ZX corresponds to NL = 5

NL:ZX = 2:5

5:ZX = 2:5

5/ZX = 2/5

Cross multiply

5*5 = ZX*2

25 = ZX*2

Divide both sides by 2

25/2 = ZX

12.5 = ZX

ZX = 12.5
