3 subtracted from twice a number=2x-3
8 less than the number=x-8
2x-3=x-8
x=-5

Hello,
{x=y-3
{x+3y=13;

{x=y-3
{y-3+3y=13;

{x=y-3
{4y=13+3;

{x=y-3
{4y=16;

{x=y-3
{y=16:4=4;

{x=4-3=1
{y=4;

{x=1
{y=4

the solution to the system of equations is (1,4)

Bye :-)

At the beginning of the year Jason had $80 in his savings account. Each month he added $15 to his account. Write in expression f

zmey [24]

So what you do is theres 12 months so multiple that by 15 and get 180 then what you do is what time 80 equals 180 and thats your answer

Which is the soluction of x/5 - 10 = 20?<br>A x = 2 <br>B x = 6<br>C x = 50<br>D x = 150

ololo11 [35]

x/5 - 10 = 20

add 10 to each side

x/5 = 30

multiply by 5

x = 150

Help!!!!!!!!!find the equation of the linear function q(16)=1 that is parralel to f(x)=1/3x+39

kkurt [141]

Answer:

$q(x)= \frac{1}{3} x -\frac{13}{3}$

Step-by-step explanation:

So you have (16, 1)

When two linear functions are parallel, they have the same slope.

So function q also has a slope of 1/3x. You have a set of points so you can plug them in a slope intercept equation to find b.

y= mx+b

m= slope

y= y-intercept

1= 1/3(16) +b

1 - (16/3) = b

b= -13/3

so then, $y= \frac{1}{3} x -\frac{13}{3}$
