Answer:

y = -3x + 8.3

Step-by-step explanation:

You need to rearrange 9x + 3y = 22 in the form y = mx +c.

9x+3y = 22

3y = -9x +22

y = -3x + 7.3

As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.

to prepare for a math test Eric study three times as long as Kendra and 1/2 as long as Geraldo. How long did Geraldo study if Ke

sp2606 [1]

Let

x---------> time in minutes used by Eric to study

y---------> time in minutes used by Kendra to study

z---------> time in minutes used by Geraldo to study

we know that

x=3y------> equation 1

x=0.5z

z=2x--------> equation 2

y=20 minutes --------> equation 3

substitute equation 3 in equation 1

x=3*20=60 minutes

find the value of z in equation 2

z=2*60=120 minutes

therefore

the answer is

The time in minutes used by Geraldo to study was 120 minutes

Solve for x: −3x + 3 < 6 x > −1 x < −1 x < −3 x > −3

Svetach [21]

Consider the inequality $-3x+3$

First, add (-3) to both sides of inequality:

$-3x+3+(-3)$

Then multiply by (-1), remembering that multiplication by negative number changes the sign of inequality:

$3x>-3.$

Now divide by 3:

$x>-1.$

Answer: correct choice is A.
