Which equation is a function of x?
x = 5
x = y squared + 9
x squared = y
x squared = y squared + 16
Answers
Answer:
x squared = y
Step-by-step explanation:
FunctionsThings can get more complicated, but based on the examples given, for an equation to be a function of x, it must have a single y, where the y is not raised to a power.
Option 1: x=5
This equation doesn't have a y, so it isn't a function of x.
Option 2: x = y squared + 9
This equation has y raised to a power, so it isn't a function of x
Option 3: x squared = y
This equation has a y, and the y isn't raised to a power. This is a function of x.
Option 4: x squared = y squared + 16
This equation has y raised to a power, so it isn't a function of x
Determining functions graphicallyIf the equations are graphed, the graphs must pass a vertical line test (a vertical line drawn anywhere should not intersect the graph more than once).
Option 1: x=5
x=5 represents a vertical line, so it fails the vertical line test (the vertical line would overlap and intersect it infinitely many times).
Option 2: x = y squared + 9
x = y squared + 9 is a sideways parabola. A vertical line will cross it twice in several places
Option 3: x squared = y
x squared = y is a parabola that opens upward. It will pass the vertical line test
Option 4: x squared = y squared + 16
x squared = y squared + 16 is a hyperbola (fancy graph shape) that won't pass the vertical line test.

Answers
Answer:
z = -6
Step-by-step explanation:
5z + 2 = 3z - 10
Subtract 3z from both sides
2z + 2 = -10
Subtract 2 from both sides
2z = -12
Divide each side by 2
z = -6
So, the answer is z = -6

If 120% of a is equal to 80% of b, then what is the value of a+b in terms of a and b?
Answers
80% of b
120% = 120/100 =1.2
80%= 80/100 = 0.8
1.2a=0.8b | ÷1.2
1a = 2/3 b
1.2a=0.8b | ÷0.8
1b=1.5a
(a+b) = ((2/3b)+ (1.5a)) =2/3b + 1.5a
*not 100% sure
Answer:
120/100 a = 80/100 b
12/10 a = 8/10 b
10 (12/10) a = 10 (8/10) b
12a= 8b
3a= 2b
a+b in terms of a
b = 3/2×a
a+ 3/2×a = 5/2×a
a+b in terms of b
a = 2/3×b
b + 2/3.b = 5/3×b

what is –2.5(7.5 – 3x)?
Answers
Answer:
-18.75 + 7.5x
Step-by-step explanation:
-2.5(7.5 - 3x)
you can seperate it into
-2.5 * 7.5 and -2.5 * -3x
-2.5 * 7.5 = - 18.75
-2.5 * -3x = 7.5x
so... -2.5(7.5 - 3x) = -18.75 + 7.5x
Mai started a new exercise program. On the second day, she walked 5 minutes more than on the first day. On the third day, she increased her walking time from day 2 by 20% and walked for 42 minutes. Mai drew a diagram to show her progress.
Answers
Answer:
d = 30 minutes.
day one is equal to 30 minutes
day two is equal to 35 minutes
day three is equal to 42 minutes
Explanation:
The first step is to figure out how much day 2 was worth in total.
Using the model, we can see that 5 of the boxes from day three is equal to day 2.
42/6=7.
One of the boxes equals 7 minutes.
Next we find what all 5 of them equal.
7*5=35.
Day two was worth 35 minutes in total.
The next step is to figure out what d equals. In order to do that, we need to solve the equation:
d + 5 = 35.
subtract 5 from both sides.
d = 30.
Now we know that day one/D is equal to 30 minutes.
Day one: 30 minutes
Day two: 35 minutes
Day three: 42 minutes.
Hope that this is what your looking for. Have a good day and good luck!
D = 30 minutes

Step-by-step explanation:
reverse multiplication -
7=4+3x
we know one value so we just isolate the 3x
7-4=3, meaning that 3x has to be equal to 3.
Then we just do 3/3=1 so therefore x=1
Also if you wanna check it then you can plug x=1 into the equation.
4+3*x or 1=4+3=7
