Answer
2
Step-by-step explanation:
x+y=-7+2x
Reorder the terms:
y = -7+ 2x
Solving
y = -7 + 2
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.Simplifying
y = 7 + 2x
Factor: x^2 - 4x - 21

Answer:
log(35)/log(7)
Step-by-step explanation:
The change of base formula is ...
[tex]\log_b(a)=\dfrac{\log(a)}{\log(b)}[/tex]
You have b=7, a=35, so the rewrite is ...
[tex]\log_7(35)=\boxed{\dfrac{\log(35)}{\log(7)}}[/tex]
If 420 = 120%, what would 100% equal?
Answer:
350
Step-by-step explanation:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
120% = 120/100 = 120 ÷ 100 = 1.2
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 120% of what number = 420?
120% × ? = 420
? =
420 ÷ 120% =
420 ÷ (120 ÷ 100) =
(100 × 420) ÷ 120 =
42,000 ÷ 120 =
350
ProofHow do we check the result?If 120% × 350 = 420 =>
Divide 420 by 350...
... And see if we get as a result: 120%
Note:Multiply a number by the fraction 100/100,
... and its value doesn't change.
100/100 = 100 ÷ 100 = 1
n/100 = n%, any number.

In ΔMNO, n = 85 inches, o = 10 inches and ∠M=56°. Find the length of m, to the nearest inch.
Answer:
80
Step-by-step explanation:
Delta math math
The length of m in triangle MNO is approximately 80 inches.
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.
In ΔMNO, n = 85 inches, o = 10 inches, and ∠M=56°.
In this case, we are given the lengths of sides n and o and the measure of angle M. We can use the law of cosines to solve for the length of side m:
⇒ m² = n² + o² - 2 × n × o × cos(∠M)
We are given that n = 85 inches, o = 10 inches, and ∠M = 56°. We can use these values to solve for m:
⇒ m² = 85² + 10² - 2 × 85 × 10 × cos (56°)
We can use a calculator or look up the value of cos 56° to find that it is approximately 0.6. Plugging this value into the formula above gives us:
⇒ m = 79.8397 ≈ 80 inches
Therefore, the length of m in triangle MNO is approximately 80 inches to the nearest inch.

A straight line passes through 0 and (2, 6)
Circle the equation of the line
[1 mark]
Answer:
y = 3x
Step-by-step explanation:
To find out what the equation is here, divide the y coordinate by the x coordinate of the point given (2, 6). Here divide 6 by 2. That would equal 3. That means that the y coordinate is 3 times as much as the x coordinate. As a result we can make the equation y = 3x out of what we now know.

Question
Set up and solve a system of equations to solve the problem.
A jar contains n nickels and d dimes. There are 20 coins in the jar, and the total value of
the coins is $1.30. How many nickels and how many dimes are in the jar?
The jar contains
nickels and
dimes.
9514 1404 393
Answer:
14 nickels6 dimesStep-by-step explanation:
The system of equations can be written ...
n + d = 20 . . . . . . . . coins in the jar
5n +10d = 130 . . . . . value in cents
_____
Using the first equation, we can write an expression for n:
n = 20 -d
We can substitute this into the second equation:
5(20 -d) +10d = 130
100 +5d = 130 . . . . . . simplify
5d = 30 . . . . . . . . . . . . subtract 100
d = 6 . . . . . . . . . . . . divide by 5
n = 20-d = 14
The jar contains 14 nickels and 6 dimes.
