Answer (this one's written in slope-intercept form):
Step-by-step explanation:
1) Lines that are parallel to each other have the same slope. The line 
is in slope intercept form, or 
form, and the number in place of 
represents the slope. Knowing this, it looks like 
is in the place of the in that equation, so is the slope - and the slope we need to use for the answer, too.
2) Once you know a point that the line must pass through and a slope, you can write an equation with point-slope form, or 
. is the slope and 
and 
are the x and y values of the point it must pass through. So, substitute for , 0 for , and -3 for . Simplify and isolate y to put it in slope-intercept form:
3) Thus, 
is the answer. It's written in slope-intercept form.
All you have to do is combine like terms here...all the x's and then all the constants. 2.3x + 2x -.2x = 4.1x; 14 + 15 = 29, so the perimeter is 4.1x + 29, A above.
I think it's 745 remainder 4

Answer:
a=9
Step-by-step explanation:
To solve this proportion, we have to get the variable, a, by itself.
First, cross multiply.
6/a=18/27
Multiply the denominator of the first fraction by the numerator of the second, and the numerator of the second by the denominator of the first.
a*18=6*27
18a=162
Now, 18 and a are being multiplied. In order to get a by itself, perform the opposite of what is being done. They are being multiplied, so the opposite would be division. Divide both sides by 18.
18a/18=162/18
a=162/18
a=9
So, the proportion, with 9 substituted in for a, will be:
6/9=18/27
