PLS HELP! If f(x) = -9x + 12, and f(x) = -6, find x.

aivan3 [116]

Answer:

Step-by-step explanation:

You can rewrite thosee two equations as -9x+12=-6, because f(x)=f(x)

Now isolate x

-9x+12=-6

-9x+12-12=-6-12 (subtract 12, subtraction property of equality)

-9x=-6-12

-9x=-18 (simplify)

-9x/-9=-18/-9 (divide by 9, division property of equality)

x=2

Please help me if you can ‼️

Answer:

$y=14.5x+5$

Step-by-step explanation:

Let

x ----> the number of tickets

y ----> the price of tickets

we have the ordered pairs

(4,63) and (6,92)

step 1

<em>Find the slope of the linear equation</em>

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{92-63}{6-4}$

$m=\frac{29}{2}=\$14.5\ per\ ticket$

step 2

Find the y-intercept or initial value of the linear equation

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope b is the y-intercept

we have

$m=14.5$

$point\ (4,63)$

substitute

$63=14.5(4)+b$

solve for b

$b=63-14.5(4)$

$b=\$5$

In this context the y-intercept is a one charge fee for the ticket service

The equation is equal to

$y=14.5x+5$

it was recently estimated that domestic vehicles out numberforegin vehicles by about six to five. if there are 2673 vehicles in

klio [65]

The question is an example of a ratio problem. This implies that

$\begin{gathered} \text{Domestic vehicles ratio=6} \\ \text{Foreign vehicles ratio=5} \\ Sum\text{ of vehicles ratio =5+6=11} \end{gathered}$

Therefore, le the number of domestic vehicles be x. We can say that;

$\begin{gathered} \frac{6}{11}=\frac{x}{2673} \\ 11x=16038 \\ x=\frac{16038}{11} \\ x=1458 \end{gathered}$
