Answer:
Sample Answer: A linear function has a constant rate of change, while a nonlinear function does not. For a table of values to be linear, the outputs must have a constant rate of change as the inputs increase by 1. On a graph, the function must be a straight line to be linear.
Answer:
On a graph, it is easy to remember whether a function is linear or nonlinear. Nonlinear means the graph is not a straight line. The graph of a nonlinear function is a curved line. If it is straight, then it is linear. On a table, you can determine whether a function, in tabular form, is nonlinear by observing that the jump in y varies for each unit of change in x.

- Class A has a greater spread.
Jack's family left home at 9:00 AM and drove to the amusement park at 60 mph. They spent 7 hours at the park and then drove back home. On the way home, traffic was bad and they drove 20 mph slower than in the morning. They got home at 8:00 PM. How far is the amusement park from Jack's home?
Answer:
96
Step-by-step
the distance from the amusement to jack's home is x (mile, x>0)
jack's family went to the amusement park at: 9 + x/60
On the way home, traffic was bad and they drove 20 mph slower than in the morning⇒ they drove: 60 - 20 = 40 mph
they left the amusement park at: 20 - x/40
have the following equation:
(20 - x/40) - (9+ x/60) = 7
⇔ 4 = x/40 + x/60
⇔ x = 96
so the distance from the amusement park to jack's home is 96 mile
Distance of amusement park from Jack's home = 96 miles
Let the distance from Jackie's house to the amusement park be x.She drove at a speed of 60 mph to get to the amusement park.
Now, formula for time is;Time = distance/speed
Time; t1 = x/60 hours
Now, we are told she spent 7 hours at the park. Thus; t2 = 7 hoursOn her way back home from school, we are told she drove 20 mph slower than her speed in the morning. Thus, speed = 60 - 20 = 40 mphThus; time; t3 = x/40
Now, she left home by 9 am and got home by 8pm same day. This is a total of t = 11 hoursThus;
t1 + t2 + t3 = 11
Plugging in the relevant values;
(x/60) + 7 + (x/40) = 11
Rearrange to get;
(x/60) + (x/40) = 11 - 7
(x/60) + (x/40) = 4
Multiply through by 120 to get
2x + 3x = 480
5x = 480
x = 480/5
x = 96 miles

6x + 9 =27 (I need help please )
Answer:
X=3
Step-by-step explanation:
6x=27-9
6x=18/6
x=3
Answer:
x=3
Step-by-step explanation:
Alrighty lets begin.
First, subtract 9 from 9 and from 27. Your equation will look like:
6x=18
Now, divide 6 from 6x and from 18. It would look like:
6x/6 = 18/6
Then cancel out the 6's.
And finally, simplify 18/6 and you get 3.
Your answer is x = 3
<<Please mark Brainliest if possible ;) have a nice day!>>
why is math hard and important
Answer: Math seems difficult because it takes time and energy. Many people don't experience sufficient time to "get" math lessons, and they fall behind as the teacher moves on. Many move on to study more complex concepts with a shaky foundation. And then often end up with a weak structure that is doomed to collapse at some point.
Step-by-step explanation: math is important because some things in math are gonna be used in your daily life for example adding, subtracting, division Etc and also because Math helps us think analytically and have better reasoning abilities. Analytical thinking refers to the ability to think critically about the world around us. Analytical and reasoning skills are essential because they help us solve problems and look for solutions.
hope this helps
Answer:
Math is very hard, but it will benefit you later in life because you learn certain material that can help you in the real world. It's an extremely important subject

7. Mark needs to move to a new apartment and is trying to find the most affordable moving truck. He will only need to truck for one day. After checking the U-Haul website, he finds that he can rent a 10 - ft truck for $20.95 a day plus $1.89 per mile. He then checks the Public Storage website and finds the charge to be $37.95 a
day plus $1.19 per mile for the same size truck. Determine the number of miles for which the cost to rent from either company would be the same. Round the answer to the nearest mile (5 points).
Answer:
24 miles
Step-by-step explanation:
Let the number of miles = x.
U-Haul:
1.89x + 20.95
Public Storage:
1.19x + 37.95
Set the costs equal and solve for the mileage, x.
1.89x + 20.95 = 1.19x + 37.95
0.7x = 17
x = 24.29
Answer: 24 miles

Angles X and Y are supplementary. Angle X is 3 times the measure of angle Y. What is the measure of angle X?
a) 45 degrees
b) 60 degrees
c) 120 degrees
d) 135 degrees
d) 135°
Step-by-step explanation:x ; y =supplementary =>
=> x + y = 180
x = 3y
replace x
3y + y = 180
4y = 180
y = 180 : 4
y = 45°
x = 3y
x = 3×45°
x = 135°
Good luck !
Answer:
D
Step-by-step explanation:
Supplementary angle: sum equals 180 degrees cannot be a straight line(180 degrees).
Y.3 + X = 180
A.
45/3 = 15
45 + 15 = 60
B.
60/3 = 20
60 + 20 = 80
C.
120/3 = 40
120 + 40 = 160
D.
135/3 = 45
135 + 45 = 180
Use the graph to determine which statement describes f(x)
O A. f(x) does not have an inverse function, because its graph fails the
horizontal line test.
O B. f(x) has an inverse function, because its graph passes the
horizontal line test.
C. f(x) has an inverse function, because its graph passes the vertical
line test.
D. f(x) does not have an inverse function, because its graph fails the
vertical line test.
Answer:
f(x) does not have an inverse function, because its graph fails the horizontal line test. ⇒ A
Step-by-step explanation:
The vertical line test is used to show that the graph represents a
function or not
If the vertical line crosses the graph in more than one point, then the graph does not represent a functionIf the vertical line crosses the graph in only one point in different positions, then the graph represents a functionThe horizontal line test is used to show that the function has an
inverse or not
If the horizontal line crosses the graph of a function in more than one point, then the function has no inverseIf the horizontal line crosses the graph of a function in only one point in different positions, then the function has an inverseLet us look at the given graph
→ The graph represents a parabola, which represents the function f(x)
∵ Any horizontal line drawn will cross the graph in more than one point
∴ f(x) has no inverse
∴ f(x) does not have an inverse function, because its graph fails the
horizontal line test.
Help 33-37 please will score as brainliest
Answer:
See below
Step-by-step explanation:
Quadratic function is in general form of:
y = ax^2 + bx + cThe function has a minimum if a > 0 and maximum if a < 0
The minimum or maximum point is a vertex of the graph
A vertex is the point x = -b/2aWhen b = 0, the min or max point equals to value of c.
33. It has maximum of -134. It has minimum of 735. It has minimum at x = - 8/4 = -2f(-2) = 2*(-2)^2 + 8(-2) + 7 = 8 - 16 + 7 = - 1
36. It has maximum at x = -18/2(-3)= 3g(3) = -3*3^2 + 18*3 - 5 = -27 + 54 - 5 = 22
37. It has minimum at x = - 6/(2*3/2) = - 2f(-2) = 3/2*(-2)^2 + 6(-2) + 4 = - 6 - 12 + 4 = - 14

2x - 6 = 9
Answer:
False
Step-by-step explanation:
This is false because:
1) In order to solve this, we cam use the addition property of equality
2) First, you can add 6 to -6 and 9
New Equation: 2x = 15
3) Now divide 2 with 2 and 15
New Equation: x = 7.5
You can also check by inserting 8 into the equation.
2(8) - 6 = 9
16 - 6 = 9, this is not true.
Therefore, this statement is false. x = 7.5

7(x - 3) = 4(x + 5)
HELP ASAP
Step-by-step explanation:
7(x - 3) = 4(x + 5)
7x - 21 = 4x + 20
3x = 41
x = 13.67
Let's solve your equation step-by-step
7(x-3)=4(x+5)
Step 1:Simplify both side of the equation
7(x-3)=4(x+5)
(7)(x)+(7)(-3)=(4)(x)+(4)(5) (Distribute)
7x+-21=4x+20
7x-21=4x+20
Step 2:Subtract 4x from both sides
7x-21-4x=4x+20-4x
3x-21=20
Step 3: Add 21 to both sides
3x-21+21=20+21
3x=41
Step 4: Divide both sides by 3
3x/3 =41/3
Answer: x=41/3

Help me -2 (8 - e) = 2 - e
Answer:
e = 6
Step-by-step explanation:
Step 1: Write equation
-2(8 - e) = 2 - e
Step 2: Solve for e
Distribute -2: -16 + 2e = 2 - eAdd e to both sides: -16 + 3e = 2Add 16 to both sides: 3e = 18Divide both sides by 3: e = 6Step 3: Check
Plug in e to verify it's a solution.
-2(8 - 6) = 2 - 6
-2(2) = -4
-4 = -4
