Answer:
D. y=2x-2
Step-by-step explanation:
The format for the equation of a line is y=mx+b, where m is the slope and b is the y-intercept of the line.
The slope of this line is 2
The y-intercept of this line is -2
Therefore, the equation for this line should look like y=2x-2

f(x) and g(x) are not closed under subtraction because when subtracted, the result will be a polynomial, the correct option is B.
What is Closure Property?According to Closure Property, when something is closed, the output will be same as the input.
The polynomials f(x) and g(x) can be seen in the image.
On subtracting the two polynomials, the output will be a polynomial and so it is closed under subtraction.

Which expression is equivalent to 2^2divided by 2/2^4
Answer: 32
Step-by-step explanation:
The expression that is equivalent to 2^2 divided by 2/2^4 would be calculated as:
= 2^2 ÷ 2/2^4
= 4 ÷ 2/16
= 4 ÷ 1/8
= 4 × 8
= 32
The expression would be equal to 32 based on the above calculation
what is 1 7/8 + 2/8 ???
Answer:
The answer is 2.375.
Step-by-step explanation:
17 / 8 = 2.125.
2 / 8 = 0.25.
2.125 + 0.25 = 2.375.
Solve the Equation
–x + 8 + 3x = x – 6
A. x = –18
B. x = –14
C. x = 2
D. x = 4
Answer:
x= -14
Step-by-step explanation:
-x+3x-x=-8-6
x= -14
-x+8+3x=x-6
the first thing we need to do is move the x's to the left and the numbers to the right
when moving a number from one side to another it's sign is changed
-x+3x-x=-6-8
x=-14
Find the measure of QS.
S9T 10 R 21 F 4x+5 Q
A. 35 B, 20 C. 27 D. 29
Answer:
C. 27
Step-by-step explanation:
((4x + 5) + 10)*10 = (21 + 9)*9 (two secants intersecting)
(4x + 5 + 10)*10 = (30)*9
(4x + 15)*10 = 270
40x + 150 = 270
40x = 270 - 150 (subtraction property of equality)
40x = 120
Divide both sides by 40
40x/40 = 120/40
x = 3
✔️QS = (4x + 5) + 10
Plug in the value of x
QS = 4(3) + 5 + 10
QS = 12 + 5 + 10
QS = 27

The distance between two stars is 9.0 x 10 to the power of -3 light years. A light year is equal to
5.88 x 10 to the power of 12 miles. What is the distance, in miles, between the two stars
Answer:
The distance between the two stars in miles is 5.292 * 10^10 miles
Step-by-step explanation:
Here, we want to make a conversion from light year to miles
To make this conversion, we simply are going to multiply the light year by the miles
Mathematically, we have this as;
9 * 10^-3 * 5.88 * 10^12
= 52.92 * 10^9
= 5.292 * 10^10 miles

Use property of exterior angles:
Exterior angle = sum of non-adjacent interior anglesHere we have:
∠D + ∠E = ∠EFG∠EFG = ∠EFH + ∠HFG = 90° + 42° = 132°So the equation is:
2x + 64° = 132°2x = 132° - 64°2x = 68°x = 68°/2x = 34°If you think it is not 34°, then your question must be asking to find something else (e.g. angle D, which is 68°)

x/5 - g = a for x
how can i find x?
Answer:
X = 5a+5g
Step-by-step explanation:
Adding g on both sides gives:
X/5 = a+g
Now dividing 5 on both sides gives us the value of x which is:
X = 5(a+g)
Hence X=5(a+g) or X=5a+5g( multiplying by 5 gives us 5a and 5g)
How can exponential growth be used to make predictions?
PLEASE! 10 POINTS! For what number A does the equation 3Ax - 24 = 5x - 9 + x have no solutions for x?
Answer:
3Ax-6x = 15
3x(A-2)=15
If A were 2, the left side of the equation would be 0 and it wouldn't equal 15 no matter what the value of x is. So A is 2

In 1995, the population of a town was 33,500. It is decreasing at a rate of 2.5% per decade.
a. Identify whether the function is a growth or decay function.
b. Write the function, f(n), that expresses the population of the town after (n) decades.
c. What is the population in the year 2025 to the nearest hundred?
Answer:
See belowStep-by-step explanation:
Initial date = 1995Initial population = 33500Decrease rate = 2.5% per 10 yearsa. It is a decay function as number of population is decreasing over time
b. f(n) = 33500*((100 - 2.5)/100)^n = 33500*(0.975)^n
c. In year 2025, n = (2025 - 1995)/10 = 3
f(3) = 33500*(0.975)^3 = 31100 rounded up
1.Encuentra la ecuación de la circunferencia que tiene como ecuación ordinaria (x-4)² + (y+5)²= 25 2- encuentra la ecuación general de la circunferencia que tiene como ecuación ordinaria (x+1)² + (y+9)²=49
Responder:
1) x² + y²-8x + 10y + 16 = 0
2) x² + y² + x + 18y + 33 = 0
Explicación paso a paso:
A partir de la pregunta, debemos expresar la ecuación en la forma estándar de un círculo expresado como;
x² + y² + 2gx + 2fy + c = 0 donde;
(-g, -f) es el centro.
1) Para la ecuación (x-4) ² + (y + 5) ² = 25
Expande el paréntesis;
(x-4) ² + (y + 5) ² = 25
x²-8x + 16 + y² + 10x + 25 = 25
x²-8x + 16 + y² + 10y + 25-25 = 0
Recopile términos similares;
x² + y²-8x + 10y + 16 + 0 = 0
x² + y²-8x + 10y + 16 = 0
Por lo tanto, la ecuación requerida es x² + y²-8x + 10y + 16 = 0
2) Para la expresión (x + 1) ² + (y + 9) ² = 49
x² + x + 1 + y² + 18y + 81 = 49
x² + x + 1 + y² + 18y + 81-49 = 0
Recopile términos similares;
x² + y² + x + 18y + 82-49 = 0
x² + y² + x + 18y + 33 = 0
Por tanto, la ecuación requerida es x² + y² + x + 18y + 33 = 0

2/3x=8 X=12
3/2x=6 X=4
Step-by-step explanation:
Answer:
a. x = 12
b. x = 4
Step-by-step explanation:

Multiply both sides by 3;
[tex]\frac{2x}{3} *3=8*3\\\\2x=24[/tex]
Divide both sides by 2;
x = 12
b. [tex]\frac{3x}{2}=6[/tex]
Multiply both sides by 2;
[tex]\frac{3x}{2}*2=6*2\\\\3x=12[/tex]
Divide both sides by 3;
x = 4
Solve the following system of equations:
-2x + y = 1
-4x + y = -1
A: (3, 1)
B: (-1, 3)
C: (-1, -3)
D: (1, 3)
Answer:
x=1,y=3
correct answer is (1,3)
Step-by-step explanation:
We can quickly eliminate y by subtracting one equation from the other
(-2x+y=1)-(-4x+y=-1)
2x=2
x=1
plug x=1 into equation 1
-2(1)+y=1
y=1+2=3

Use elimination to solve the system.
2x + 3y = 1
5x – 4y = 14
help would be appreciated :)
Answer:
x = 2, y = -1
Step-by-step explanation:
To solve this with elimination, we first multiply the first equation by -2.5
Our new equations are:
-5x - 7.5y = -2.5
5x – 4y = 14
After adding these two equations together, the x cancels out and we have:
-11.5y = 11.5
Divide both sides by -11.5
y = -1
Plugging this value into y in one of the equations we have:
2x + 3y = 1
2x + 3(-1) = 1
2x - 3 = 1
Add 3 to both sides
2x = 4
Divide both sides by 2
x = 2
What is CD??
A.7
B.10
C.13
D.21
Answer:
13
Step-by-step explanation:
Is there more info to this problem? I'm assuming both triangles are congruent. If so then you can assume that BC = CD
If that's the case then set them equal to each other to solve for x then plug x back into the side for CD to get the value
6x-5 = 4x+1
2x = 6
x = 3
Plug into CD 4(3) +1
