Solve the equation systems or set the values x = 1.8 and y = -0.9 on the equation and check the equality.
A.
6x - 5y = 15
L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3
R = 15
L ≈ R
x + 2y = 0
L = 1.8 + 2(-0.9) = 1.8 - 1.8 = 0
L = R
B.
4x + 5y = 8
L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7
R = 8
L ≠ R
C.
x - 2y = 4
L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6
R = 4
L ≈ R
4x + 5y = 8
L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7
R = 8
L ≠ R
D.
6x - 5y = 15
L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3
R = 15
L ≈ R
x - 2y = 4
L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6
R = 4
L ≈ R
We have two probability solutions: A and D.
But I think, Your answer is A.
ANSWER :
1. 2ab + c^2
2. (a + b)^2 or (a^2 + 2ab + b^2)
3. 2ab
EXPLANATION :
Recall that the area of a triangle is 1/2 base x height.
and the area of a square is the square of its side.
From the problem, we have 4 congruent triangles.
The area of four triangles is :
The area of the square is :
Then the total area will be :
It is equivalent to the area of the whole square in which the side is (a + b)
So that's :
Since both expressions are equal, we can equate them :
Fourty-three and seventy-eight hundreths. Hope this help :)
Answer: y = 32,000(1.08)^c
Step-by-step explanation:
Given that the initial population
P = 32000
t = 1 year
R = 8%
Y = 34,560
To predict y the number of people living in town after x years
t = x
Y = P(1 + 8%)^t
Y = 32000( 1.08)^x
The point slope form of line is y+4 = -4( x+3)
<h3>What is point slope of form?</h3>
The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point.
Given:
m=4
We know the general form is
y - b = -4(x - a)
So, from the graph attached below
b= -4, a= -3
So, y-(-4)= -4(x-(-3))
y+4 = -4( x+3)
Hence, point slope form of line is y+4 = -4( x+3).
