The statements that are true about the solution to the system of equations are
y coordinate, of the solution is = (-8) ,
x coordinate, of the solution is = (9) , and
The ordered pair that is solution to the system lies in Quadrant IV .
In the question ,
the system of equations are given as
4x+3y = 12 ...(1)
and 2x +3y = -6 ...(2)
to solve for x and y , we subtract equation (2) from equation(1) .
So , On subtracting , we get
(4x+3y)-(2x+3y)= 12-(-6)
4x+3y-2x-3y = 12+6
4x-2x +3y-3y = 18
2x = 18
x = 18/2
x = 9
Put x=9 in equation [tex](1)[/tex], we get
4(9)+3y=12
36+3y=12
3y = 12-36
3y = -24
y= -24/3
y = -8
Since x coordinate is +9 and y coordinate is -8 ,
so the solution lies in Quadrant IV.
Therefore , The statements that are true about the solution to the system of equations are
y-coordinate, of the solution is = (-8) ,
x-coordinate, of the solution is = (9) , and
The ordered pair that is solution to the system lies in Quadrant IV .

(-1, 0)
Answers
Considering the expression of a line, the slope of the line that passes through the pair of points (3, -4) and (-2,0) is -1.
Linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope of the line can be calculated using:
m= (y₂ - y₁)÷ (x₂ - x₁)
Equation in this caseIn this case, being (x₁, y₁)= (3, -4) and (x₂, y₂)= (-1, 0), the slope m can be calculated as:
m= (0 - (-4))÷ (-1 -3)
m= (0 +4)÷ (-1 -3)
m= 4÷ (-4)
m= -1
Finally, the slope of the line is -1.

solve |2x-6|<0 not urgent. But its for a test
Answers
The inequality expression given as |2x - 6 | < 0 has a solution of x > 3
How to solve the inequality?From the question, the inequality is given as
|2x-6|<0
This gives
|2x - 6 | < 0
Remove the absolute bracket
So, we have the following representation
2x - 6 > 0
Add 6 to all sides of the inequality
So, we have
2x - 6 + 6 > 0 + 6
Evaluate the like terms
So, we have
2x > 6
Divide through by 2
x > 3
Hence, the solution to the expression is x > 3

⇒ BC = 5 miles and AC = 9 miles
We need to find the distance from Jessica's school to her house in miles.
i.e., we need to find AB
Using Pythagoras theorem,
AC² = AB² + BC²
9² = AB² + 5²
AB = √(81 - 25)

The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables.

The equation of the given line in the diagram above is expressed as: b. y = 2/3x.
How to Find the Equation of a Line?For a line that passes through the origin (0, 0) of a graph, the equation that represents the line can be written in slope-intercept form as y = mx, where the slope of the line is represented as m.
The y-intercept of this type of line is zero, that is why we have the equation expressed as y = mx. Where the y-intercept is not equal to zero, the equation of the line would be expressed as y = mx + b, where b is the y-intercept and m is the slope of the line.
Find the slope of the line using two points on the line, (0, 0) and (3, 2):
Slope of the line (m) = (2 - 0)/(3 - 0)
Slope of the line (m) = 2/3.
To write the equation of the line, substitute m = 2/3 into y = mx:
y = 2/3x.

For the equation |2-2x| = 14, find all values of x which makes the equation true
Answers
Answer:
x=-6,8
Step-by-step explanation:
First, let's observe our equation, there is an absolute value (|x|) that means 'x' will have two answers most likely positive and negative.
First we will take off the lines.
now we have
2-2x=14
next minus 2 out of both side of the equation
2 - 2 -2x = 14- 2
-2x =12
now we will divide -2 from both side of the equation
[tex] \frac{ - 2x = 12}{ - 2} [/tex]
we will cancel out - 2
[tex]\frac{x = - 6}{1} [/tex]
x= -6
We aren't done yet since this is an absolute value we have to convert the sum of the equation ( 14) to negatives now which will be in this case (-14)
your new equation will look like this
2-2x= -14
next minus 2 out of both side of the equation
2 - 2 -2x = -14- 2
-2x = - 16
now we will divide -2 from both side of the equation
[tex] \frac{ - 2x = - 16}{ - 2} [/tex]
we will cancel out - 2
[tex] \frac{x = 8}{1} [/tex]
x = 8
Check:x = -6
2 - 2x = 14
2 - 2(-6) = 14.
2 + 12 = 14✓.
x= 8
2 - 2x = -14
2 - 2 (8) = -14
2 - 16 = -14✓

On Bennett’s 5th birthday, his uncle invested $2,000 in a CD account that was locked into a 3.2% interest rate, compounded daily. How much will Bennett have in the account when he turns 18?
Answers
The amount Bennet will have when he turns 18 will be equal to $3020.
Compound interest is the type of interest charged by banks or institutions on individuals in which the amount after 1 year becomes the principle for the next year. It can be calculated daily, monthly or yearly etc. The formula for compound interest compounded daily will be
A = P(1 + r/n) ^nt, where A is the amount, P is the principle, which is equal to $2000, r is rate of interest which is 3.2% or 0.032, n is compounding frequency which is equal to 365 and t is the time which is equal to 13 years. Now, the amount will be
A = 2000(1 + 0.032/365) ^365×13
A = 2000(1.51)
A = $3020 which is the required amount.
