What is a function?A function can be defined as a law, rule or expression that shows the relationship between two variables in an equation.
These variables are called;
The independent variableThe dependent variableFrom the information given, we have the function;
f(x) = (x + 1)² g(x) = 2x³To determine the composite function, we have to substitute the value of g(x) as x in the function f(x), we have;
(f º g)(x) = (2x³ + 1)²
expand the bracket
(f º g)(x) = 4x⁶ + 1
Hence, the function is (f º g)(x) = 4x⁶ + 1

Pickle cannot get the cart up the ramp. In order to be successful he should
make the ramp longer.
make the ramp shorter.
make the ramp steeper.
back up and begin with a running start.
Answer: Make the ramp longer
making the ramp shorter and making the ramp steeper would be the same, and backing up wouldn't really help
Pickle should make the ramp longer in order to be successful.
Option A is the correct answer.
What is a ramp?The ramp refers to a sloped surface that connects a lower level to a higher level.
We have,
- A longer ramp will provide a more gradual slope, which will make it easier for the cart to move up the ramp.
- If the ramp is too short,
The slope will be too steep and it will be difficult to push the cart up.
- Making the ramp steeper will also make it more difficult to push the cart up.
- Starting with a running start may provide some initial momentum, but it will not address the underlying problem of the ramp being too short.
Thus,
Pickle should make the ramp longer in order to be successful.

Mindy looks outside her window and sees limp tomato plants in the garden. She quickly waters the plants, and by the end of the day, the plants are upright with firm stems. How did watering the tomato plants straighten the stems?
Answer:
Do you have options.

Which equation represents a line which is perpendicular to the y-axis?
Answer:
The real answer is y=5
Step-by-step explanation:
because its horizontal
y=5 represents a line which is perpendicular to the y-axis
What is Straight line?A line is an infinitely long object with no width, depth, or curvature. Thus, lines are one-dimensional objects
We need to find the equation which represents a line that is perpendicular to the y-axis
A line perpendicular to the y axis will be a horizontal line, the equation of any horizontal line is y=b where b is the y-intercept.
In the given options
x=-6
y=x-4
y=5
and x=-2y
The only horizontal line is y=5
Hence, y=5 represents a line which is perpendicular to the y-axis

y=3x+3 y=−2x+3 how many solutions does the system have
Answer: One solution
Step-by-step explanation:
y = 3x + 3
y = -2x + 3
-----------------------------------------------------------------------------------------------------------
To solve this, you need to understand a few things:
a) If two lines have the same slope but different y-intercepts, they are parallel when graphed and thus do not have any solutions
b) If two lines have the same slope and same y-intercepts, they are the same line when graphed and thus do not have infinitely many solutions
c) If two lines have different slopes (and/or y-intercepts), they have one solution
-----------------------------------------------------------------------------------------------------------
These two lines have different slopes but the same y-intercept (condition c)
So they have one solution
Find value of x
I need it fastttttt
Answer:
x=1
Step-by-step explanation:
you have to put x on one side. send -10 to the other side. Add 10 on both sides to delete 10.
7x-10+10=3x-6+10
now it leaves you with 7x=3x+4
Now you have to send 3x to the other side because you are solving for x. subtract both sides by 3x to delete 3x on the other side.
7x-3x=3x-3x+4
how it leaves you with 4x=4
now you divide both sides by 4
4/4x=4/4
Hence, x=1
Answer:
standard form: 4x - 4 = 0
factorisation: 4(x - 1) = 0
solutions: x = 4/4 = 1
therefore, x is 1
