Write an equation of the line that passes through the point (0,4) and (2,6) in slope-intercept form.
Answer:
y=x+4
Step-by-step explanation:
Use slope formula: (y2-y1)/(x2-x1)
(6-4)/(2-0)
2/2
1
Slope Intercept Form: y = m(slope) times x plus b(y-intercept)
y=1x+b
Plug in one of your points into the equation:
4=1(0)+b
4=0+b
4=b
Final Answer: y=x+4

If I got a 60 on a test , and I have a 92 in that class , what will my grade be ? (please answer i am stressing so much I might get gray hairs)
Answer:
There's no way to answer this question 100% accurately, because we don't know your teacher's grading scale, or how much tests and quizzes are weighted for your grade in the class. That being said, one test shouldn't bring your grade down too much. As the year goes on, and more assignments are put in the gradebook, it will even out. If you get a 100 percent on 3 tests, and a 60 percent on one test, it evens out to a 90 percent.
If you need more help, type in "Rogerhub grade calculator." It's a website that is very helpful in calculating your grade for the year. Hope this helps! :)
What is the slope of the line that passes through
the points (-1,3) and (5, 7)?
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
For this situation we will use this equation:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
This lets us find the slope from a set of points (m being the slope of course), with each one representing a coordinate from our set. (e.g. 7 could be [tex]y_{2}[/tex])
First let's define which coordinates will represent each:
(-1,3): [tex]x_{1} ,y_{1}[/tex]
(5,7): [tex]x_{2} ,y_{2}[/tex]
Now that we have this, we can fill in our coordinates: [tex]m = \frac{7-3}{5-(-1)}[/tex]
Next we simplify: [tex]m = \frac{4}{5+1}[/tex] (double negative = positive)
And simplify some more: [tex]m = \frac{4}{6}[/tex]
Finally, we find the GCF (greatest common factor) of 4 and 6, which is 2, and divide by that to further simplify the fraction: [tex]m = \frac{2}{3}[/tex]
Therefore, the slope of the line that passes through the points (-1,3) and (5,7) is [tex]\frac{2}{3}[/tex].

Which of the following linear equations is in standard form? A. 3x + 2y = 3 B. 2y = 3x - 2
C. y = 3x - 2 D. 3x + 2y - 2 = 0
Answer: A
Step-by-step explanation: The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).
Basic math equations and calculations play an important role in many jobs tasks. If you were working at a grocery store and your cash register was not automatically calculating the 20% off sale on someone's cereal--how would you solve this issue from the options listed below? If the cereal was normally $2.88, I would... 1 point Take $2.88 and times it by 80 for a sale price of $2.30. Subtract $0.20 for a sale price total of $2.68. Divide 20 from $2.88 for a sale price total of $0.15.
Given :
Price of cereal without off, C = $2.88 .
Percentage off, P = 20% .
To Find :
Price after applying 20% off.
Solution :
Final price = Initial price - 20 % of initial price
[tex]F = 2.88 - 2.88\times \dfrac{20}{100}\\\\F=2.88-0.576\\\\F=\$ 2.304[/tex]
Therefore, final price after sale is $2.304 .
Hence, this is the required solution.
Solve 5x − 2(2x − 1) = 6
Answer: x = 8
Step-by-step explanation:
The answer begins with the distributive property, multiplying positive 2 times the elements in parenthesis.
5x - (2)(2x - 1) = 6
5x - 4x - 2 = 6
1x = 6 + 2
x = 8

The following are trinomial EXCEPT.
A. x+7 B. 5x²+2x-7
C. 7x³+2x+5 D. 7x⁴+3x-9

If you travel 1000 feet in 5 minutes, what is your speed per minutes?
Answer: 200 feet
Step-by-step explanation:
1000feet/5feet= 200feet
Answer:
200 feet per minute
Step-by-step explanation:
Speed = Distance/Time
Since you want to find the "per minute", you would just divide the total distance by the number of minutes:
1000 feet / 5 minutes = 200 feet per minute
Find the answer for x.
Answer:
x=25
Step-by-step explanation:
since this is a triangle you would add up all the measure of this and set it equal to 180. 90 is the side with the box. so it would be 2x+15+x+90=180 then solve for x and you would get your answer.

write the equation of the line parallel to 2x - 3y = 0 and passes through the point (5, 4).
Answer:
2x - 3y = 2Step-by-step explanation:
Parallel lines have same slope
Given line, in slope intercept form
2x - 3y = 03y = 2xy = 2/3xParallel line is
y = 2/3x + bUsing point (5, 4) to find b
4 = 2/3*5 + bb = 12/3 - 10/3b = 2/3y = 2/3x + 2/3 in slope-intercept form or
2x - 3y = 2 in standard form

[tex]\sf{4n=4-20}[/tex]
[tex]\sf{4n= -16}[/tex]
[tex]\sf{n=\dfrac{-16}{4}}[/tex]
[tex]\sf{n = -4}[/tex]
Hope it helps :)
Answer:
-4
Step-by-step explanation:
To solve, you need to isolate the number with the variable (in this case, 4n). To do that, get rid of the 20 on the left side. To do THAT, do the opposite which is subtract; do it to both sides. This leaves you with 4n= -16.
Now, to get rid of the 4 and be left with just the n, do the opposite of what is given. In this case, n is multiplied by 4 so divide by 4 on both sides to isolate n. This gives you the answer of -4.
Hope it helps!

Marcus has to add -3mn^3 and -5mn^3 to complete the polynomial.
Marcus is rewriting a polynomial by combining like terms
What is polynomial?Polynomial equation is equation of independent variables.
Here, questions seems to be incomplete.
In polynomial, it can be of maximum endless number of term or minimum 1 term. Marcus can add any number or repeat any number. And if he revised the old number than the number could be -3mn^3 and -5mn^3.
Thus, Marcus has to add -3mn^3 and -5mn^3 to complete the polynomial.

What is the equation of a line that passes through the point (9, −3) and is parallel to the line whose equation is 2x−3y=6?
Enter your answer in the box
Answer:
y = 2/3x - 9
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
Point (9, - 3)
2x - 3y = -6
Step 2: Rewrite given equation
-3y = -2x - 6
y = 2/3x + 2
So our m = 2/3 (Parallel lines have the same slope but different y-intercepts)
Step 3: Find y-int of parallel line
y = 2/3x + b
-3 = 2/3(9) + b
-3 = 6 + b
b = -9
Step 4: Write parallel line equation
y = 2/3x - 9
Solve:

x = 35
-10x = -100
x = 10
Solving a linear equation: Your hourly wage is $9.75 per hour plus
$0.80 for each unit you produce. How many units
must you produce in 1 hour so that your hourly wage
is $19.35?
Answer:
You must produce 12 units
Step-by-step explanation:
19.35 - 9.75=9.60
9.6/0.8=12
Answer:
the answer is 12 units
Step-by-step explanation:
u get 9.75 an hour and 0.80 for every unit so subtract 9.75 from 19.35 and u get 9.60 now divide that by 0.80 and u get 12 units
Which ratio is different from the others? > 8 to 15 ,15:8 ,8:15 8/15
