What value of n makes 4n +20 = 4? *
Step-by-step explanation:
Answer:-[tex]\sf{4n+20=4}[/tex]
[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.

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

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
h-(-2.22)=-7.851 solve for h
Answer:
[tex]\boxed {h = -10.071}[/tex]
Step-by-step explanation:
Solve for the value of [tex]h[/tex]:
[tex]h - (-2.22) = -7.851[/tex]
The opposite of [tex]-2.22[/tex] would be [tex]2.22[/tex]:
[tex]h - (-2.22) = -7.851[/tex]
[tex]h + 2.22 = -7.851[/tex]
-Subtract both side by [tex]2.22[/tex]:
[tex]h + 2.22 - 2.22 = -7.851 - 2.22[/tex]
[tex]\boxed {h = -10.071}[/tex]
So, the value of [tex]h[/tex] is [tex]-10.071[/tex].

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 prime factorization of 36?
22 × 9
2 × 32
22 × 32
3 × 13
Answer:
2 x 2 x 3 x 3
Step-by-step explanation:
Answer:
a composite number is written as a product of all of its prime factors, we have the prime factorization of the number. For example, the number 36 can be written as a product of primes as: 36 = 2² x 3². The expression 2² x 3² is said to be the prime factorization of 36.

Answer:
2.25 miles
Step-by-step explanation:
If she can walk 3/4 of a mile in 20 minutes you need to multiply 3/4 by 3 because 20 times 3 is 60 and there is 60 minutes in a hour
Write the equation of a line ( slope intercept form y = mx + b)
Answer:
y=1/4x-1

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
You are planning a road trip and you are preparing the songs you will be listening on the Road. You start by downloading 5 songs for $7.50 on one day and 8 songs for $12 the following day.
How much do 2 songs cost?
Answer:
$3.00
Step-by-step explanation:
7.50/5 = 1.5
12/8 = 1.5
Since each song costs $1.50 each, multiply the cost by the number of songs.
1.50(2) = 3
$3.00

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).
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.
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].
