Step-by-step explanation:
Write the equation of the line through
(0, 4) and (2, 0) in slope-intercept form.
Answer: y = -2x + 4
Step-by-step explanation: slope intercept form is "y=mx+b" where m is the slope and b is they y intercept. the y intercept is when x=0 and it's given to us in the question. the y intercept is (0,4). so y=4. we can plug that into the equation to now have y=mx + 4.
now we need to find the slope. we can do this by plugging the two points into the formula [tex]\frac{y2-y1}{x2-x1}[/tex]. so we'd have [tex]\frac{0-4}{2-0}[/tex] to get -4/2 which is -2. -2 is the slope.
so the final answer is y = -2x + 4
What does negative 2 over 3 > −1 indicate about the positions of negative 2 over 3 and −1 on the number line? (4 points) Group of answer choices negative 2 over 3 is located to the right of −1 negative 2 over 3 is located on the left of −1 negative 2 over 3 is located on the right of 0, and −1 is located on the left of 0 negative 2 over 3 is located on the left of 0, and −1 is located on the right of 0
Answer:
negative 2 over 3 is located to the right of -1
Step-by-step explanation:
-1 is further to the left than negative 2/3. Negative 2/3 is closer to 0.
Negative 2/3 is between -1 and 0.
These statements eliminate the other possible answers.

3. y= 9 - 2x²
4. y = 2x + 2
5. y = 3x² + x² + 2
9514 1404 393
Answer:
yesnoyesnoyesStep-by-step explanation:
The function is quadratic if the highest degree of any term is 2. Equations 2 and 4 have degree 1, so are linear (not quadratic) functions. Equations 1, 3, and 5 have terms of degree 2 (at most), so are quadratic functions.
_____
We assume that two terms of degree 2 in equation 5 is intentional. If one of those is supposed to be of degree 3 (or more), then that function is not quadratic.
Find the Distance rounded to a whole number.
Give the distance between (2,1) and (5,2)
Answer:
[tex]\sqrt{10}[/tex]
Step-by-step explanation:
The distance between two points can be found using the Pythagorean Theorem [tex]a^{2} + b^{2} = c^{2}[/tex].
This is because, if you connected your two points with a line, that line could be defined as the hypotenuse of a right triangle. the base of that triange is the distance between the x coordinates ([tex]x_{2} -x_{1}[/tex]) and the height by the distance between the y coordinates ([tex]y_{2} - y_{1}[/tex]). Sine these are the sides of the right triangle, they are equal to a and b above (c is the hypotenuse that we are trying to find). So, we calculate the two distances above and get 3 and 1 (for x and y respectively). 3^2 + 1^ 2 =10. So the answer is square root 10.

We see an increase of 10y per x, which is where we get "10x"
This means that at x = 1, y = 15, which is where we get "+ 15"

A landfill has 30,000 tons of waste in it. Each month it accumulates an average of 585 more tons of waste. Let m represent the number of months.
What is a function that represents the total amount of waste after m months?
Answer:
f(m) = 585m + 30, 000
Step-by-step explanation:
First you need to set up your variable which is m which makes f(m) and since each month gives 585 tons per month we have the variable attached to that (585m). However, we already start with 30,000 so we add that in. You can check the answer by replacing m with a number, which for me I will choose 10, which gives me 35,850 which makes sense.

In 60 seconds , Darrell walks 90
90
meters. Describe the unit rate at he wall
Answer:
1.5 sec by meters
Step-by-step explanation:
90 meters/60 sec=1.5
Darrel walks at a unit rate of 1.5 m/sec.
What is speed?Speed is defined as the rate of change of position in unit time.
Mathematically,
Speed = Distance/Time
Now it is given that,
Distance in walk by Darrell = 90 meters
Time taken by Darell to walk 90 meters = 60 seconds
Therefore Speed i.e unit rate of walk is given as,
Unit rate of walk = Distance in walk by Darrell / Time taken by Darell to walk 90 meters
⇒ Unit rate of walk = 90/60 m/sec
⇒ Unit rate of walk = 3/2 m/sec
⇒ Unit rate of walk = 1.5 m/sec
Thus, Darrel walk at a unit rate of 1.5 m/sec.
