Mia has a budget of $250 to spend on a health club membership. The monthly membership fee is $20, and there is a one-time regist

Leokris [45]

So we cant go over $250

35+20n=250

now that i put the question in an expression we can take the 35 away from both sides

35+20n=250
-35. -35
_____________
20n=215

now divide 20 by both sides to get (n) alone

20n=215
________
20

n= 10.75

we round down because we cannot exceed the limit, thus

Evaluate for given value: m x 4/5 for m = 7/8

Ray Of Light [21]

(7/8)*(4/5)=(7/(4*2))*(4/5) =7/10, you can write it also as 0.7

Write an equation of the line passing through the point(8.2) that is parallel to the line 6x-9y=-7

Vinil7 [7]

First off, remember that parallel lines always have the same slope. If they have the same slope, then let's find the slope of the line we have so we can use it.

$6x-9y=-7\\-9y=-6x-7\\y=\frac{-6}{-9}x+\frac{-7}{-9}\\y=\frac{2}{3}x+\frac{7}{9}$
The equation for a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept.

If $y=\frac{2}{3}x+\frac{7}{9} and [tex]y=mx + b$ , then m = slope = 2\3.
Thus, the slope of the line is 2/3.

So now we know that m = 2/3, but we don't know what b equals...
Oh wait, we have an equation that contains m, x, y, and b, and using the point (8, 2) we now have (x, y) and can plug those into the equation $y = mx +b$

$y=mx+b\\(2)=(\frac{2}{3})(8)+b\\2=\frac{16}{3}+b\\b=2-\frac{16}{3}=\frac{6}{3}-\frac{16}{3}=\frac{-10}{3}\\\\b=\frac{-10}{3}$

So now we know both m and b, so plug them into the equation of a line in slope-intercept form:

$y= mx+b\\y=(\frac{2}{3})x+(\frac{-10}{3})\\\\y=\frac{2}{3}x-\frac{10}{3}$
