Answer 1

Answer: $y=x\n\n\Downarrow S_(OX\ for\ y < 0)\n\ny=|x|\n\n\Downarrow T_{\vec{a}=[0;-3]}\n\ny=|x|-3$

$y=x\n\nfor\ x=0\to y=0\to(0;\ 0)\n\nfor\ x=2\to y=2\to(2;\ 2)\n\n\nlook\ at\ the\ picture$

Step-by-step explanation:

Solve for x and y simultaneously:
X-2y=3
4xsquared-5xy+6y=3

Answers

x - 2y = 3
4x^2 - 5xy + 6y = 3
lets solve for x the first and substitute in the second:
x = 3 + 2y
4(3 + 2y)^2 - 5(3 + 2y)y + 6y = 3
4(9 + 12y + 4y^2) - 15y - 10y^2 = 3
36 + 48y +16y^2 - 15y - 10y^2 = 3
6y^2 + 33y + 33 = 0
we can solve using the general quadratic formula:
y = (-33 +- √(33^2 - 4*6*33))/12
y = (-33 +- √(297))/12
so there are 2 solutions for y:
y1 = (-33 + √(297))/12
y2 = (-33 - √(297))/12
pick one and then substitute the y value in the first equation to find x

x = 3 + 2y

4(3+2y)^2 - 5(3+2y)y + 6y = 3
4(4y^2 + 12y + 9) - 5(3y + 2y^2) + 6y - 3 = 0
16y^2 + 48y + 36 - 15y - 10y^2 + 6y - 3 = 0
6y^2 + 39y + 33 = 0
6y^2 + 6y + 33y + 33 = 0
6y(y+1) + 33(y+1) = 0
(y+1)(6y+33) = 0
y = -1, -11/2

x = 3 + 2y
x = 3 + 2(-1)
x = 3 + 2(-11/2)
x = 1, -8

What is the LCD between these fractions 4/9 and 2/3

Answers

The least common multiple that is divisible by both a and b is the smallest positive integer. The LCD between these two fractions 4/9 and 2/3 is 9.

What is LCM?

The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.

The LCD of two fractions is the LCM of the denominator of the fractions.

Since the denominator of the two fractions is 3 and 9. Therefore, the LCM of the two denominators are,

LCM = 9

Hence, the LCD between these two fractions 4/9 and 2/3 is 9.

Answer: Least common denominator = 9

Step-by-step explanation:

The LCD is the lowest multiple of the denominators

9 is a multiple of 1 × 9 or 3 × 3. So since 3 is the denominator of 2/3, 9 is the LCD.

2/3 is equivalent to 6/9.

A concert charges $24.50 per daily adult ticket and $13.75 per child’s ticket. A group of 90 people paid $1560.00 for tickets. Write a system of equations that could be used to find x, the number of adult tickets purchased, and y, the number of children's tickets purchased?I know the answer i just need to know how to solve it. Thanks :)

Answers

x=adults
y=childern

x+y=90
24.50x+13.75y=1560

so
mutliply the first equation by -13.75 and add to second equaiton

-13.75x-13.75y=-1237.5
24.50x+13.75y=1560 +
10.75x+0y=323

10.75x=322.5
divide both sides by 10.75
x=30

x=30
sub back

x+y=90
30+y=90
minus 30 both sides
y=60

x=30
y=60

Which of these numbers is between 1 and 5/6?
A. 6/7
B. 4/5
C. 4/7
D. 11/6

Answers

The number that lies between the points 1 and 5/6 is 4/5

What is a fraction in math?

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.

Given here: The proper fraction 5/6=0.83

Now 4/5=0.8

6/7=0.85

11/6=1.83

4/7=0.57

Thus 4/5 must lie between 5/6 & 1

Hence, The correct option is B) 1/5 as no other option lies in the required interval.
