Answer:
(3,12)
Step-by-step explanation:
y = 3x + 3
y = 6x -6
x = 3
y = 12
= (3,12)
Answer:
All you have to do, is find an x that if used in both equations, both equal the same y.
3 x 3 + 3 = 12
6 x 3 - 6 = 12
So, the only thing here is (3, 12)

A house cost $185,500 in 2000. By the year 2015, the value was $132,000. What was the growth
rate as a percent for that 15-year period?
Answer:
their was no growth rate it lost 53,500 in those 15 years at a rate of about 3,566 a year
Step-by-step explanation:
The growth rate is the percentage increase and it is the increase with respect to the original thus growth rate will be 28.84%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
The cost in 2000 is $185500
Cost in 2015 is $132000
Change or increase = (185500 - 132000)
% increase = change/original
% increase = (185500 - 132000)/185500 = 28.84%
Hence "The growth rate is the percentage increase and it is the increase with respect to the original thus growth rate will be 28.84%".

FIND THE VERTEX AND GRAPH THE PARABOLA OF
F(x) = -2X^2 - 8X + 3
(minus 2x squared minus 8x plus 3)
════════ ∘◦❁◦∘ ════════
Answer : (-2,11)════════════════════
Known thaty = -2x² - 8x + 3
════════════════════
Way to do + explanation#First, find the x coordinate first by using the formula of -b/2a
x = -b/2a = -(-8)/2(-2) = 8/-4 = -2
#After getting the x, find the y
y = -2(-2)² - 8(-2) + 3
y = -2×4 +16 + 3
y = -8 + 16 + 3
y = 11
So the vertex is
(-2,11)
════════════════════
Answer:
the vertex is (-2, 11)
Step-by-step explanation:
F(x) = -2X^2 - 8X + 3 can be rewritten as -2(x^2 + 4x) + 3.
We complete the square of x^2 + 4x, obtaining x^2 + 4x + 4 - 4 = (x + 2)^2 - 4
and then we substitute this last result into F(x) = -2(x^2 + 4x) + 3:
F(x) = -2[ (x + 2)^2 - 4 ] + 3, which simplifies to:
F(x) = -2(x + 2)^2 + 8 + 3, or F(x) = -2(x + 2)^2 + 11
Comparing this to the vertex equation (x + h)^2 + k, we see that h must be -2 and k must be 11.
Thus, the vertex is (-2, 11).

6) Pardeep has a rectangular sheet of paper of size 44cm x 20cm. He rolled it
along its breadth and a cylinder is formed. Find volume of the cylinder.
Answer:
[tex]V=1398.4\ cm^3[/tex]
Step-by-step explanation:
Given that,
Pardeep has a rectangular sheet of paper of size 44cm x 20cm. He rolled it along its breadth and a cylinder is formed.
When he rolled it along its breadth, 20 is equal to circumference i.e.
20 = 2πr
r is radius of base of cylinder
r = 3.18 cm
44 cm will be height of the cylinder.
The volume of the cylinder is given by :
[tex]V=\pi r^2 h\\\\V=\dfrac{22}{7}\times (3.18)^2 \times 44\\\\V=1398.4\ cm^3[/tex]
So, the volume of the cylinder is [tex]1398.4\ cm^3[/tex].
Solve the equation by factoring. Tasha is planning an expansion of a square flower garden in a city park. If each side of the original garden is increased by 7 m, the new total area of the garden will be 144 m^2m 2. Find the length of each side of the original garden.
Answer:
Step-by-step explanation:
Area of enlarged garden will be 144 sq meters. Each side will be √144 = 12 meters.
Side of original garden = 12-7 = 5 meters l.

Equality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityAlgebra I
Terms/CoefficientsCoordinates (x, y)Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
4x - 3y = -20
-x - 8y = 5
Step 2: Rewrite Systems
-x - 8y = 5
[Addition Property of Equality] Add 8y on both sides: -x = 8y + 5[Division Property of Equality] Divide -1 on both sides: x = -8y - 5Step 3: Redefine Systems
4x - 3y = -20
x = -8y - 5
Step 4: Solve for y
Substitution
Substitute in x: 4(-8y - 5) - 3y = -20[Distributive Property] Distribute 4: -32y - 20 - 3y = -20Combine like terms: -35y - 20 = -20[Addition Property of Equality] Add 20 on both sides: -35y = 0[Division Property of Equality] Divide -35 on both sides: y = 0Step 5: Solve for x
Define original equation: -x - 8y = 5Substitute in y: -x - 8(0) = 5Multiply: -x = 5[Division Property of Equality] Divide -1 on both sides: x = -5Answer:
x = -5
y = 0
Step-by-step explanation:
4x-3y=-20
-x-8y=5 then x = 8y-5
substitute for x
4(8y-5)-3y = -20
32y-20-3y = -20
29y = 0
y = 0
4x-0 = -20
x = -5
Ram obtains 40% of the marks in a paper of 200 marks. Shyam is ahead of Ram by 25% of Ram' s marks, while Bhuvan is ahead of Shyam by one month of his own marks. How many marks does Bhuvan get?
Answer:
First, we start with:
"Ram obtains 40% of the marks in a paper of 200 marks"
In this case, 200 marks represent the 100%
Then how much is the 40%?
we have the relations:
40% = X
100% = 200 marks
Now we can take the quotient of both equations:
(40%/100%) = X/200marks
(40%/100%)*200marks = X = 80 marks
So Ram obtained 80 marks.
Now we have:
"Shyam is ahead of Ram by 25% of Ram's marks"
Now the 100% is the number of marks that Ram has, this is:
100% = 80 marks
And Shyam has 25% more than that, then we have:
125% = X
Same as before, we take the quotient of both equations:
(125%/100%) = X/80 marks
1.25*80 marks = 100 marks.
Shyam has 100 marks.
The last part is (this is not written correctly, it says "one month", it should be "one-ninth")
"while Bhuvan is ahead of Shyam by one-ninth of his own marks."
if his own marks are X, we have the equation
X = 100 + (1/9)*X
X - 1/9*X = 100
X*(8/9) = 100
X = (9/8)*100 = 112.5
So Bhuvan has 112.5 marks

find the value of x
Answer:
x = 20
Step-by-step explanation:
Each side would be 60. 60/3 would be 20. So x = 20
Answer:
x = 20
Step-by-step explanation:
Looking at the image you've posted here. We can see this triangle is equilateral. That also means 3x is 60°, as are the other two angles. All you really have to do is dividing both sides of the equation by 3 to get x to equal 20.
