Put the dot on the 5 on the Y-axis
Step-by-step explanation:
Put the initial dot on the 5 on the y-axis (vertical), then it's rise over run if plotting a line. Since it's 3/4 you would go up 3 and over to the right four. You can get the rest of the line by going down 3 from the initial point on five, down left 3.
The y-intercept of the line is (0, -5) and plot the coordinate points (0, -5) and (4, -8) on the graph.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
The given equation is y+2= -3/4 (x+4).
Graph the line using the slope and y-intercept, or two points.
Slope: -3/4
y-intercept: (0, -5)
Plot the coordinate points (0, -5) and (4, -8)
Hence, plot the coordinate points (0, -5) and (4, -8) on the graph.

An engineer is estimating the weight of a steel beam. The actual weight of the beam is 152 pounds. The engineer's estimate is 150 pounds.
Find the absolute error and the percent error of the engineer's estimate. If necessary, round your answers to the nearest tenth.
Answers
Answer/Step-by-step explanation:
To find the absolute difference, we simply have to see by how much pounds the estimation was off.
The real measure was 152 pounds, the estimated weight was 150.
D = 152- 150 = 2 pounds.
For the percent of error, we divide the absolute difference (52) by the real value () and we'll get the % of error. So,
%D = 52 / 152 = 0.0034, so 0.34%

{x: x belongs to N and (x-1)(x-2) = 0}, finite set or infinite set?
Answers
Explanation:
We have a set of x values such that (x-1)(x-2) = 0. Breaking that down leads to either x-1 = 0 or x-2 = 0 through the zero product property. Solving each of those equations gets us x = 1 and x = 2 as the two items in this set.
So the original set your teacher gave you turns into the roster form {1,2}. There are two items in this set and we can see it's a finite set since it does not go on forever. Note that everything in this set is a natural number.

a 450-square-foot apartment in new york city costs $540,00 what is the price per square foot?
Answers
Answer:
$1200
Step-by-step explanation:
Let cost of 1 square foot be x
So, Cost of 450 square feet = 450x
We are given that A 450-square-foot apartment in New York City cost $540,000.
So, 450x = 540000
x= [tex]\frac{540000}{450}[/tex]
x= 1200
Cost of 1 square foot = $1200
Hence the price per square foot is $1200

The statement (A) Electrons can have a measured radius. and statement (D) Electrons do not have energy, the energy is determined by the orbit are correct.
What is Bohr's atomic model?In the Bohr atomic model, electrons are grouped according to their energy levels. The energy level at which an electron is located determines its energy.
As we know,
The aspects covered by Bohr’s atomic model are:
Electrons can have a measured radius.Electrons do not have energy, the energy is determined by the orbit.Energy is absorbed by electrons as they transition from a lower to a higher energy state. The electron emits energy when it transitions from a higher to a lower energy level. Visible light is one way to view this energy.
Thus, the statement (A) Electrons can have a measured radius. and statement (D) Electrons do not have energy, the energy is determined by the orbit are correct.

Answer: Electrons do not have energy, the energy is determined by the orbit." or A and b
Step-by-step explanation: The correct answer is, "Electrons do not have energy, the energy is determined by the orbit."
In the Bohr model of the atom, electrons are arranged in energy levels. The energy of an electron is determined by the energy level in which it is found.
When electron an the electron moves from a lower to a higher energy level it absorbs energy. When the electron moves from a higher to a lower energy level, it radiates energy. This energy is observed in the form of visible light.
Thus, in the Bohr's model, electrons are arranged in energy levels. The energy level where an electron is found determines its energy.

Answers
Answer: f(x) = 1.19x, where f(x) is the total cost, and x is the cost per bottle
Cost of 15 bottles: $17.85
Step-by-step explanation:
This question describes a straightforward relation between cost per bottle, and cost for all the bottles. As such, simply equate one variable to the value of one bottle, and f(x) as the value of every bottle.
Hope it helps :) and let me know if you want me to elaborate.
P.S. f(x) can simply be substituted for "y"
Let
no of bottles be x
.The function is given by
[tex]\\ \sf\longmapsto f(x)=1.19x[/tex]
Now
Bottles=15Cost:-
[tex]\\ \sf\longmapsto f(15)[/tex]

Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.
