Answer:
independent: tdependent: dStep-by-step explanation:
The way the equation is written, d is the dependent variable; t is the independent variable (on which d depends).
Answer:
the independent variable is t (time) and the dependent variable is d (distance)
Step-by-step explanation:
Time is called independent variable because time determines the distance and it stands alone, while distance is dependent variable because the length of distance is determined with the time, meaning when time (t) changes, the distance changes too.
for ex. if t=1, d= 0.8+6 (1) = 6.8

what’s the domain using inequalities for this graph?
Answer:
-9 ≤ x < 2
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We can see from the graph that our x-values span from -9 to 2. Since -9 is closed dot, we include it in our domain. Since -2 is open dot, it is excluded from our domain:
[-9, 2) or -9 ≤ x < 2
Evaluate f(x) = -4x + x2 + 16 for f(-4).
Answer:
[tex]f(-4)=48[/tex]
Step-by-step explanation:
Value of functions
To evaluate a function for a given value of x, we replace the x for the value and perform the resulting operations.
The given function is (corrected):
[tex]f(x)=-4x+x^2+16[/tex]
We need to find f(-4), so we use x=-4:
[tex]f(-4)=-4*(-4)+(-4)^2+16[/tex]
[tex]f(-4)=16+16+16[/tex]
[tex]\boxed{f(-4)=48}[/tex]

8x
what is the constant of the function f(x)=8x(squared 2) - 7x+6
Answer:
6
Step-by-step explanation:
A constant has no variables multiplied to it.
f(x) = 8x² - 7x + 6
8x² and -7x would have variables and would be terms.
6 would just be a constant cause it doesn't change.

The area of a rectangle is greater than 60 ft. The width of the rectangle is 2x - 3 ft and the
length is 12 ft. Write an inequality and solve for x
Answer:
Inequaliy: 2x-3(12)>60
X>48
Step-by-step explanation:
Since area of a rectangle is W(L)=A
The inequality given right here including length And width and area Plugged in would be
2x-3(12)>60. (It’s >60 because the area stated in the problem said to be greater then 60 so we put a Greater then sign)
Combine like terms and solve
2x-36>60
Add 36 on both sides
2x>96
Divide 2 on both sides to isolate variable
x>48
Check:
2(50)-36>60 ( I used 50 because it’s greater then 48 and it’s a easy number to work with for just a check)
solve:
100-36>60
64>60✔️

A family has two cars. During one particular week, the first car consumed 30 gallons of gas and the second consumed 20 gallons of gas. The two cars drove a
combined total of 1050 miles, and the sum of their fuel efficiencies was 45 miles per gallon. What were the fuel efficiencies of each of the cars that week?
Answer:
30 mpg15 mpgStep-by-step explanation:
Let x represent the fuel efficiency of one of the cars. Then 45-x is the fuel efficiency of the other. The total miles driven is then ...
miles = (gallons)×(miles/gallon)
20x +30(45-x) = 1050
-10x +1350 = 1050 . . . simplify
300 = 10x . . . . . . . . . . add 10x-1050
x = 30 . . . . . . . . . . . . . divide by 10
45-x = 45-30 = 15
The car using 20 gallons got 30 miles per gallon; the car using 30 gallons got 15 miles per gallon.

the ratio of red marbles to yellow marbles placed in a bag is 2:7. More marbles are added to the bag: 3 red and 3 yellow marbles. Maria states that the ratio is still the same since equal amounts of red and yellow marbles were added to the bag
Answer: False.
Step-by-step explanation:
Initially, the ratio is 2:7
This means that if we have 2 red marbles, we must have 7 yellow ones.
The quotient here is 7/2 = 3.5
Now, if you add 3 marbles of each colour, then we have:
2 + 3 = 5 red marbles
7 + 3 = 10 yellow marbles.
Now the ratio is 5:10
This means that for every 5 red marbles, we have 10 yellow ones.
But now we can divide both numbers by the same positive integer, because they have a common factor equal to 5.
5/5 = 1
10/5 = 2
Then we have:
5:10 = 1:2
So the new ratio is 1:2
Then the ratio changed when we added the new marbles, which means that Maria was wrong.

Answer:
The answer is 25
Step-by-step explanation:
