how to solve 1.2x+1.4y=2.7 and 0.4x-0.3y=0.9 in substitution
Answers
Answer:
x=0.8712, y=1.1818
Step-by-step explanation:
1.2x+1.4y=2.7 --(1)
0.4x-0.3y=0.9--(2)
1.2x=2.7-1.4y
x=(2.7-1.4y) / 1.2 --(3)
substitute (3) in (2)
[tex]0.4(2.7-1.4y) / 1.2 -0.3y=0.9[/tex]
[tex](1.8 - 0.56y) \frac{1}{3} - 0.3y = 0.9[/tex]
times both sides with 1/3
[tex] \frac{1}{3} (1.08 - 0.56y( \frac{1}{3} ) - 0.3y = 0.9)[/tex]
1.08-0.3=0.56y+0.1y
0.78=0.66y
y=1.1818
substitute y in (3)
x=2.7-1.4(1.1818) /1.2
x=0.8712

Daria bought
a skein of alpaca yarn for $47.50, a skein

yarn for $16.50, and a pair of knitting
needles for $3.86. How much did she
spend in all? Describe how you calculated
your answer
Answers
The total amount Daria spent on all her purchases is $100
In order to determine the total amount Daria spent on all her purchases, the cost of each item has to be added together.
Addition is a mathematical operation that can be used to determine the total sum of two or more values. other basic mathematical operations are subtraction, multiplication and division.
Total amount spent = cost of a skein of alpaca yarn + cost of a skein
of angora yarn + cost of a skein of wool yarn + cost of a pair of knitting
needles
$47.50 + $32.14 + $16.50 + $3.86 = $100

Answers
Answer:
steps below
Step-by-step explanation:
1) f(x) = (-3ax⁴ + ax² +x) / (2x⁴ + x³ - ax² + 8x) ... degree of the denominator = degree of the numerator (-3a) / 2 = 5 / 4
-12a = 10
a = - 5/6
2) 3-n > n+ 10 ... degree of the denominator < degree of the numerator
2n < -7
n < - 3.5
The largest inter value is -4
3) f(x) = (x²+3x-4) / (2x²+7x-10)
f(2) = (2²+3*2-4) / (2*2²+7*2-10) = 6 / 12 = 1/2
x->∞ : divide x² both numerator and denominator, any number/ x -> 0
f(x) = (1 + 3/x - 4/x²) / (2 + 7/x - 10/x) = (1 + 0 - 0) / (2 + 0 - 0) = 1/2

The coordinates of point J are (-7, 2), and the midpoint of JK is at L (3, 5). What are the coordinates of point K?
Answers
The required coordinate of the point K is (13, 8).
Given that,
The coordinates of point J are (-7, 2), and the midpoint of JK is at L (3, 5), the coordinates of point K is to be determined.
Coordinate, is represented as the values on x-axis and y-axis of the graph.
here,
The coordinate of the midpoint (x, y) is given as,
x = (x₁ + x₂)/2 ; y = (y₁ + y₂)/2
Substitute the value in the above equation,
3 = (-7 + x₂)/2 ; 5 = (2 + y₂)/2
x₂ = 13 ; y₂ = 8
Thus, the required coordinate of point K is (13, 8).

In 2010, the population of a city was 168,000. From 2010 to 2015, the population grew by 7%. From 2015 to 2020, it fell by 6%. How much did the population decrease from 2015 to 2020, to the nearest 100 people?
Answers
Answer:
169,000 people
Step-by-step explanation:
increase from 2010-2015:
168000/100 = 1680 = 1%
1680 x 7 = 11,760 people
population at 2015 = 168000+11760 = 179,760
decrease from 2015-2020:
179760/100 = 1797.6 = 1%
1797.6 x 6 = 10,785.6 people
population at 2020 = 179760-10787.6 = 168,974.4 people
rounded to the nearest 100 = 169,000 people

How much force is needed to push a 10kg ball to an acceleration of 0.8 m/s2?
Answers
Answer:
Mass of the object (m)= 10kg
Acceleration of the object (a)= 2m/s^2
Force acting on the object (F)= ?
Solution
F = m × a
F = 10 × 2
F= 20N
The force acting on the object is 20N.
Step-by-step explanation:
8N of force is needed to push a 10kg ball to an acceleration of 0.8 m/s²
What is Force?Force is an influence that can change the motion of an object.
Given,
Mass of the object (m)= 10kg
Acceleration of the object (a)= 0.8m/s²
We need to find Force acting on the object (F)= ?
Force=Mass ×Acceleration
F = m × a
Plug in the values of mass and acceleration
F =10 × 0.8
F= 8N
Hence, The force acting on the object is 8N.
