The function d = 8f + 24 represents the monthly cost d (in dollars) of a group of f members joining the fitness club. a. Identify the independent and dependent variables (don’t say f and d).
Answer:
D represents the dependent variable: the monthly cost in dollars is your independent variable
F represents the independent variable: the number of members joining the fitness club
Step-by-step explanation:
The amount of money depends on how many members come and join the fitness club because more money is spent more with more members
write an equation that is perpendicular to x - 3y =3 and passes through the point (5,-9) in slope-intercept form.
9514 1404 393
Answer:
y = -3x +6
Step-by-step explanation:
The perpendicular line will have the coefficients of x and y swapped (and one of them negated), and will have a constant appropriate to the point the line needs to go through.
The equation will look like ...
x -3y = 3 . . . . . . . . . . . . . given line
3x +y = constant . . . . . . perpendicular line
where "constant" can be found by substituting for x and y.
3x +y = 3(5) +(-9)
3x +y = 6 . . . . equation in standard form
To put this in slope-intercept form subtract 3x:
y = -3x +6

Ellie took a taxi from her house to the airport. The taxi company charged a pick-up fee of $1.50 plus $5 per mile. The total fare was $76,50, not including the tip. Write and solve an equation which can be used to determine m, the number of miles in the taxi ride.
I dont understand this
Answer: 1.50+5m=76.50 m=15
Step-by-step explanation:
The required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
pick-up fee = $1.50 plus $5 per mile
Since, m is the number of miles in the taxi ride
So, equation for pick-up fee for m miles,
pick-up fee = $1.50 + $5m
Now total fare = $76,50
Thus, required equation to determine m is given as,
1.50 + 5m = 76.50
Subtracting 1.5 both the side we get,
1.50 + 5m - 1.5 = 76.50 - 1.5
⇒ 5m = 75
or, m = 75/5
⇒ m = 15
Thus, the required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.

What is slope of the line?"The slope of tee line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]"
What is y-intercept?"The point at which the graph intersects the Y-axis."
What is slope intercept form of the line?"y = mx + c, where m is the slope of the line and c is the Y-intercept."
For given question,
We have been given the graph of a line.
From the graph, we can observe that the line is passing through the points (4, 4) and (-6, 0)
Using slope formula the slope of the line would be,
[tex]\Rightarrow m=\frac{4-(-6)}{4-0}\\\\\Rightarrow m=\frac{10}{4}\\\\\Rightarrow m=\frac{5}{2}[/tex]
Also, the line intersects y-axis at y = 2
This means the y-intercept is c = 2
Using the slope-intercept form of the line the equation of the line would be,
[tex]y=mx+c\\\\y=\frac{5}{2}x+2[/tex]
Point E(-4, y) lies on the given line.
So, this point satisfies the equation of the line.
[tex]\Rightarrow y=\frac{5}{2}(-4)+2\\\\ \Rightarrow y=-10+2\\\\\Rightarrow y=-8[/tex]
Therefore, the value of y is -8

2 math question please help me 30 point
Answer:
1. B: 12 BB 18 FB,, 2.
Step-by-step explanation:
1. make the equation (198 + 33x) + 24x = 882 because there are a certain number of each ball (x) and 6 more footballs. since each football is 33 dollars, you do 33 x 6 which is 198, and then keep 33x and 24x. It is all equal to 882 since that is the final price. First, you subtract 198 on each side and combine the like terms (33x + 24x). Now it is 684= 57x and you divide 684 by 57, which equals 12. That means that there are 12 basketballs and 12 + 6 footballs, which is 18.
2. You cannot solve the problem or do any problem without distributing first. I'm unsure how else to explain it.

Explanation:
Line L is the horizontal line. Any point on this line has y coordinate y = 4, so the equation is simply y = 4.
You could say the equation is y = 0x+4, which shows the slope is 0. But I think y = 4 is the better answer.
