Solve the system by substitution. And show your work
-9y-10=x
5x+6y=-11
Answer:
x = -1, y = -1
( -1 , -1 )
Step-by-step explanation:
plug in -9y - 10 for x
5 ( -9y - 10) + 6y = -11
-45y - 50 + 6y = -11
-39y - 50 = -11
-39y = 39
y = -1
then plug in
-9(-1) - 10 = x
9 - 10 = x
x = -1

Answer:
The equation of the exponential function will be:
[tex]y\:=\:10\cdot \left(\frac{1}{5}\right)^x[/tex]Step-by-step explanation:
The general exponential function is defined as
y = abˣ
Here,
a is the initial value and b is the growth factorFrom the table, it is clear that the y-intercept is (0, 10). Note that the y-intercept can be determined by setting x=0 and solving for y.
here
at x=0, y=10
so a = 10
If we check the y-values, it is clear that every next value of y can be obtained by multiplying the previous y-value by 1/5.
In other words, the common multiplier = b = 1/5
Thus, the equation becomes
[tex]y\:=\:10\cdot \left(\frac{1}{5}\right)^x[/tex]
Thus, the equation of the exponential function will be:
[tex]y\:=\:10\cdot \left(\frac{1}{5}\right)^x[/tex]graph of y = −4x − 1?
Answer:
Explanation: Since the equation is linear/straight in the form y=mx+c , you can determine the slope/gradient ( m ) and y-intercept ( c ). To graph this equation, you'll need to find 2 points on the line and join them together. We know one of the points is (0, 1) as the y-intercept is 1.

The total land area of Russia is about 20,000,000 km^2, or 2 x 10^7 km^2.
The total land area of Puerto Rico is about 10,000 km^2, or 2 x 10^2 km^2.
About how many times larger is Russia than Puerto Rico?
A. 2 x 10^-3 times
B. 19,990,000 times
C. 200 times
D. 2 x 10^3 times
Answer:
Im not sure but i think its 200 times
Step-by-step explanation:
Russia is 2 × 10³ times larger than Puerto Rico.
What is Exponentiation?Exponentiation is a method of writing numbers, especially larger numbers, as the power of some number. A number can be written in the exponent form as aᵇ, where 'a' is called the base and 'b' is called the power or exponent.
Total land area of Russia = 20,000,000 km² = 2 × 10⁷ km²
Total land area of Puerto Rico = 10,000 km² = 10⁴ km²
Let X be the number of times that Russia is larger than Puerto Rico.
Then we can write,
Total land area of Russia = X × Total land area of Puerto Rico
2 × 10⁷ km² = X × 10⁴ km²
X = 2 × 10⁷ km² / 10⁴ km²
X = 2 × 10⁷ × 10⁻⁴
X = 2 × 10³
Hence, about 2 × 10³ times larger is Russia than Puerto Rico.

Find the sum of the interior angle measure of a regular polygon with 20 sides
Answer:
3240°
Step-by-step explanation:
Using the formula:
sum of interior angle = (n - 2) * 180 (where n is the number of sides)
sum of interior angle = (20 - 2) * 180
sum of interior angle = 18 * 180
sum of interior angle = 3240° ANS

Answer:
The answer is D-16
Step-by-step explanation:
Since we have x on one side, and 49 degrees on the other, both angles are the same, so we subtract 1 from 49 to get 48, so that 3x has to equal 48. So we just divide 48 by 3 to get 16, so x = 16.

The sixth term of an arithmetic sequence is 3 2 , and the twelfth term is 5 2 . What is the common difference of the arithmetic sequence? The common difference is .
The sequence has a common difference, and the common difference of the arithmetic sequence is 10/3
How to determine the common difference?The given parameters are:
T6 = 32
T12 = 52
The nth term of an arithmetic progression is:
Tn = a + (n - 1) * d
So, we have:
T6 = a + 5d = 32
T12 = a + 11d = 52
Subtract both equations
a - a + 11d - 5d = 52 - 32
Evaluate
6d = 20
Divide both sides by 6
d = 10/3
Hence, the common difference is 10/3

liquid is being poured at a rate of 15 gallons per minute. How fast is it being poured in liters per hour? Use the fact that one gallon is approximately 3.785 liters, and do not round your answer.
Answer:
3,406.5 litres/hr
Step-by-step explanation:
The liquid is being poured at a rate of 15 gallons per minute.
1 minute = 1/60 hour
Thus, the rate can be written as:
15 gallons pet 1/60 hour
We are told that one gallon is approximately 3.785 liters.
Thus;
15 gallons = 15 × 3.785 litres = 56.775 litres.
Thus, the rate is;
56.775 litres per 1/60 hour
We want to find in litres/hr.
By proportion, we have it as;
(56.775 ÷ 1/60)/1 = 56.775 × 60 = 3,406.5 litres/hr
Which of the following is the best definition for the word "proportion"

Answer:
Convert to decimals:
1.5 and 0.75
Then, set up a proportion
1.5/0.75=x/1
proportion x/y=x/y
since the 3/4 and 1 are the same topic ( the room) we put them together.
Solve: 1.5/0.75=x
x=2
So 2 gallons
