The y - value is $83.99 when x = 1 which represents the total cost for 1 month of membership.
Explanation:
Given that in city W, the average cost for a gym membership is given by the equation
where y is the total cost, in dollars, for x months of membership.
We need to determine the meaning of the y - value when x = 1.
<u>The value of y:</u>
Let us determine the value of y when x = 1
Thus, substituting x = 1 in the equation
, we get,
![y=34.99(1)+49](https://tex.z-dn.net/?f=y%3D34.99%281%29%2B49)
![y=34.99+49](https://tex.z-dn.net/?f=y%3D34.99%2B49)
![y=83.99](https://tex.z-dn.net/?f=y%3D83.99)
Thus, the y - value is $83.99 when x = 1 which represents the total cost for 1 month of membership.
Answer:
Equation: y=$3(x)+$30
Total cost $42
Step-by-step explanation:
Calculation to Find the total cost of 4 hours at the aquarium using this formula
y=mx+b
Where,
y intercept=Total cost
m=$3 per hour
b=$30 Tickets
x=4 hours
Let plug in the formula
First step is to form the equation
y=$3(x)+$30
Second step is to substitute 4 hours for m and b
y=$3(4)+$30
Hence:
y=$12+$30
y=$42
Therefore the equation will be y=$3(x)+$30 while the total cost of 4 hours at the aquarium will be $42
Answer:
x = -4/3 x =1/2
Step-by-step explanation:
6x^2 +5x - 4 = 0
6 has factors of 3 and 2 and 6 and 1
4 has factors of -4 and 1 and -2 and 2, and -1 and 4
We want +5 in the middle
3* -1 + 4*2 = 5
( 3x+4) ( 2x -1) =0
Using the zero product property
3x+4 =0 2x-1 =0
3x = -4 2x =1
x = -4/3 x =1/2
Answer <u>(assuming it can be in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the line using the slope formula,
. Substitute the x and y values of (0,0) and (5,2) into the formula and simplify like so:
![m = \frac{2-0}{5-0} \\m = \frac{2}{5}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B2-0%7D%7B5-0%7D%20%5C%5Cm%20%3D%20%5Cfrac%7B2%7D%7B5%7D)
So, the slope is
.
2) Now, use the point-slope formula to write the equation of the line. Using the point-slope formula
, substitute values for
,
, and
.
Since
represents the slope, substitute
in its place. Since
and
represent the x and y values of a point the line intersects, we can substitute the x and y values of one of the given points (I chose (0,0)) into the formula as well. Then, isolate y to put in slope-intercept form:
![y-0=\frac{2}{5} (x-0)\\y = \frac{2}{5} x](https://tex.z-dn.net/?f=y-0%3D%5Cfrac%7B2%7D%7B5%7D%20%28x-0%29%5C%5Cy%20%3D%20%5Cfrac%7B2%7D%7B5%7D%20x)
