Add like terms
3x - 4
Answer:
3x-4
Step-by-step explanation:
Combine like terms, x + 5x gives you 6x but then subtract 3x and you have only 3x.
Keep 4 the same and your answer is 3x-4

List the following in order from least steep to most steep.
f(x)= -3/4x
g(x)= -5x
h(x)= 5/7x
j(x)= 11/3x
Answer:
h(x), f(x), j(x), g(x)Step-by-step explanation:
Given functions
f(x)= -3/4x g(x)= -5x h(x)= 5/7x j(x)= 11/3xTo compare steepness we'll compare absolute values of slopes
The steepness increases as the slope increases
The slopes are
3/4, 5, 5/7, 11/3Comparing the fractions
3/4 = 21/28, 5/7 = 20/28, so 3/4 > 5/7And
11/3 < 4So the order is
5/7 < 3/4 < 11/3 < 5As functions, the order is
h(x), f(x), j(x), g(x)Given that f(x)=2x-1, find f(3)
Answer:
5
Step-by-step explanation:
Put 3 where x is and do the arithmetic.
f(x) = 2x -1
f(3) = 2·3 -1 = 6-1
f(3) = 5

A rocket is launched from a tower. The height of the rocket, why in feet is related to the time after launch, X and seconds, by the given equation. Using this equation find out the time at which the rocket will reach its max, to the nearest 100th of a second y=-16x + 152x + 74
Given:
Consider the height of the rocket, in feet after x seconds of launch is
[tex]y=-16x^2+152x+74[/tex]
To find:
The time at which the rocket will reach its max, to the nearest 100th of a second.
Solution:
We have,
[tex]y=-16x^2+152x+74[/tex]
It is a quadratic polynomial with negative leading coefficient. So, it is a downward parabola.
Vertex of a downward parabola is the point of maxima.
To find the time at which the rocket will reach its max, we need to find the x-coordinate of the vertex.
If a quadratic function is [tex]f(x)=ax^2+bx+c[/tex], then the vertex is
[tex]Vertex=\left(-\dfrac{b}{2a},f\left(-\dfrac{b}{2a}\right)\right)[/tex]
Here, [tex]a=-16,b=152,c=74[/tex].
So,
[tex]-\dfrac{b}{2a}=-\dfrac{152}{2(-16)}[/tex]
[tex]-\dfrac{b}{2a}=-\dfrac{152}{-32}[/tex]
[tex]-\dfrac{b}{2a}=4.75[/tex]
So, x-coordinate of the vertex is 4.75.
Therefore, the rocket will reach its max at 4.75 second.

Answer:
(1,-8), (-6,-4), (3,7), (-6,1)
Step-by-step explanation:
In a function the x values cannot repeat. Look at each answer choice and see if an x repeats:
The first choice (top left) has the x value, -6, repeating. It cannot be a function.
The second choice (top right) does not have an x value repeat. This makes it a function!
The third choice, (bottom left) does not have an x value repeat. This makes it a function!
The fourth choice, (bottom right) does not have an x value repeat. This makes it a function!

A. The amount of time that Karen has driven since she last put gas in
her car is a function of how much gas her car needs.
B. The amount of gas Karen has to put in her tank is a function of
how large her gas tank is.
C. The amount of gas Karen has to put in her tank is a function of
how long she has driven since she last put gas in.
ANY HELP IS GREATLY APPRECIATED What is the sign of the product (−4)(6)(9)(3)?

B. Positive, because the products (−4)(6) and (9)(3) are positive and the product of two positive numbers is positive
C. Negative, because the product (−4)(6) is negative and the product (9)(3) is positive, and the product of a negative number and a positive number is negative
D. Negative, because the product (−4)(6) is negative and the product (9)(3) is negative, and the product of two negative numbers is a negative number
Answer:
c

In △FGH, FH ≅ FG. Which angles are congruent? Select both angles that are congruent
angles FGH and FHG
Step-by-step explanation:
Since this is a triangle, and the question states that FH=FG, you know that the triangle is an isosceles triangle. If you use an isosceles triangle, you know that the bottom two angles are the same degrees. Since the F is the same for both lines, you can determine that F is the top point of the triangle. As such, is you draw the triangle out, you will find the answer is angles FGH and FHG

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.

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

24 __ 3/4 = 18 is it Multiplication Division Addition Subtraction
Answer:
Multiplication
Step-by-step explanation:

Multiplication is the required operation.
What is the BODMAS rule?According to the BODMAS rule, the brackets have to be solved first followed by powers or roots (i.e. of), then Division, Multiplication, Addition, and at the end Subtraction. Solving any expression is considered correct only if the BODMAS rule or the PEMDAS rule is followed to solve it.
Given here: The equation given is 24_ 3/4=18
Let the operation be multiplication then we get
24×3/4=6×3
=18
Similarly, we can verify that no other operation yields the answer an s18 and thus the operation performed must be multiplication.
Hence, Multiplication is the required operation.

an object is moving at a speed of 4 yards every 6.5 days. express this speed in centimeters per minute. round your answer to the nearest hundredth
Answer:
0.0390cm/minStep-by-step explanation:
We are expected to do a unit conversion here.
let us convert days to minutes first
6.5days to minutes
1 day has 1440miuntes
6.5 days has x minute
cross multiply we have
x=6.5x1440
x=9360minute
let us convert yards to cm
1 yard to 91.44 cm
4 yards has xcm
cross multiply we have
x=4x91.44
x=365.76cm
the speed in cm per mins is
speed=365.76/9360m
speed=0.0390cm/min

How much is it | -7.9|?
Plllzzzzzz help mark you brainliest
Answer:
7.9
Step-by-step explanation:
When a number (or multiple numbers) is placed between two lines like this | |, that is the absolute value grouping symbol. Absolute value is the distance between the grouped number(s) and another defined number. In this case there are no other given numbers so 0 is assumed.
Now, say a friend is driving to your house and you call them to ask how far away they are from arriving (in distance), and they say "Around negative 5 miles away." That doesn't make sense! Distance can never be negative, and because absolute value is the distance between a number and another, a number within that grouping symbol can never be negative if there is a solution. Therefore, |-7.9| would be 7.9, because -7.9 is that exact amount away from 0.

Which of these is defined as a part of a line that is bounded by two end points?
ray
angle
point
line segment
Answer: Line Segment.
Step-by-step explanation:
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints. In geometry, a line segment is often denoted using a line above the symbols for the two endpoints (such as ĀB).

Hello.
The answer is choice A. angle 1 = 118, angle 2 = 118
Explanation:
The four angles above are congruent (meaning the same) to the ones beneath.
Angles 1 and 2 are also congruent, so they will measure the same.
Lets label the angles above A, B, C, D. B being the known angle, which is 118°. The angles beneath can be labelled E, F, G, H.
∠B ≅ ∠D
∠ABCD ≅ ∠EFGH
∠BD ≅ ∠FH
FH (or 1 and 2) equal 118.
