What is the equation of a line that is parallel to 2x + 3y = 3 and passes through the point (3, -4)?
Enter your answer as a slope intercept equation (y=mx+b) in the box.
Answer:
y = - [tex]\frac{2}{3}[/tex] x - 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
given
2x + 3y = 3 ( subtract 2x from both sides )
3y = - 2x + 3 ( divide through by 3 )
y = - [tex]\frac{2}{3}[/tex] x + 1 ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
• Parallel lines have equal slopes , then
y = - [tex]\frac{2}{3}[/tex] x + b ← is the partial equation
to find b substitute (3, - 4 ) into the partial equation
- 4 = - 2 + b ⇒ b = - 4 + 2 = - 2
y = - [tex]\frac{2}{3}[/tex] x - 2 ← equation of parallel line
If I get $147.00 every two weeks for child support? In a year how much would that equal up to?
Answer:
Step-by-step explanation:
52 weeks in a year
Divide 52 by 2 = 26 weeks
26 weeks x 147 dollars = 3822 dollars
Thus the answer is 3822 dollars yearly
Answer:$3,528
Step-by-step explanation:
since there are 4 weeks in a month that would mean you would have to multiply 147 by two and that would = to $294.00/month so then you would have to multiply that by 12 so then that would = to $3,528.00 a year.

perimeter of a rectangle is 36 cm . If the length of the rectangle is 12 cm . Find its area.
Answer: 72 cm
Step-by-step explanation:
So since we know its length is 12 cm, that leaves us with finding the width. You could do that by adding the two length's together to get 24, then subtract that from the perimeter to get 12. The widths being added together must equal 12 and be the same, so we can divide by 2 to get 6 cm as the width. Then multiply 6 times 12 to get 72
Answer: A=72 cm²
Step-by-step explanation:
Let the width of the rectangle be x
Hence, P=36 cm l=12 cm
P=2(l+x)
P=2l+2x
P-2l=2x
Divide both parts of the equation by 2
Thus,
[tex]\displaystyle\\x=\frac{P-2l}{2} \\\\x=\frac{36-2(12)}{2}\\\\x=\frac{36-24}{2} \\\\x=\frac{12}{2} \\\\x=6 cm\\\\[/tex]
Area A=l*x
A=12*6
A=72 cm²
Find the values of X and Y. State which theorem(s) you used.
Using alternating and corresponding angle theorem, the value of x and y are (8, 146), (86, 94) and (21, 29.5) respectively
Alternate and Corresponding Angle TheoremAlternate angle theorem states that when two parallel lines are cut by a transversal, then the resulting alternate interior angles or alternate exterior angles are congruent. Corresponding and Alternate angles are the most fundamental angles formed when two parallel lines are intersected by a transversal line.
5)
3x = 5x - 64
Reason: Alternate angles are equal
5x + 3x = 64
8x = 64
x = 8
y + 5x - 6 = 180
Reason: Angles on a straight line are equal to 180
y + 5(8) - 6 = 180
y + 40 - 6 = 180
y + 34 = 180
y = 146
6) x = 86
Reason: Alternating angles are equal to one another
y + 86 = 180
Reason = 94
7) 2y = 59
Reason: Vertical angles are equal
y = 59 / 2
y = 29.5
2y = 3x - 4
Reason: Alternate angles are equal
2(29.5) = 3x - 4
59 = 3x - 4
3x = 59 + 4
3x = 63
x = 21

Sample Response: The points on the number line do represent additive inverses. 3 and −3 are a zero pair, and when added they equal zero. The two numbers are the same distance from zero but in opposite directions. The following are reasons why 3 and −3 are additive inverses. Check all of the conditions you included in your response.
When two numbers added together result in 0, this is known as additive inverse. Using this notion, points on a number line are used to depict additive inverse.
Explain the term additive inverse?To get a result equal to 0, add the original number and the additive inverse by simply switching the sign of the integer. On the basis of negation of a original number, the characteristics of additive inverse are listed below. For instance, if x is the starting number, then -x is x's additive inverse.The dotted points with the numbers 3 and -3 are the places on the number line.
To determine whether the points show an additive inverse:
Points 1 and 2 add up to 0.
3 + (-3) = (3 - 3) = 0
When two numbers added together result in 0, this is known as additive inverse.
Using this notion, points on a number line are used to depict additive inverse.

What exactly is a monthly payment?A monthly payment is a payment made every month to pay off loans or advances. It's similar to EMI.
Mary takes out a loan for $6,000 at a simple interest rate of 12% to be paid back in 36 monthly installments.
The total payback = P× r/100 × T + P
Here P = $6,000 , r = 12, and T = 3 years
The total payback = 6,000 × 12/100 × 3 + 6,000
The total payback = 6,000 × 0.12 × 3 + 6,000
The total payback = $8,160
The total payback of the borrowings will be $8,160 over a three-year period. The monthly payment for this will be,

m∠3 + m∠4 + m∠5 = 180°
m∠5 + m∠6 =180°
m∠2 + m∠3 = m∠6
m∠2 + m∠3 + m∠5 = 180°
The statements that are always true regarding the diagram of interior and exterior angles of a triangle include the following:
C. m∠5 + m∠6 =180°.
D. m∠2 + m∠3 = m∠6.
E. m∠2 + m∠3 + m∠5 = 180°.
What is the Linear Pair Postulate?The Linear Pair Postulate states that the measure of two (2) angles would add up to 180° provided that they both form a linear pair. This ultimately implies that, the measure of the sum of two (2) adjacent angles would be equal to 180º when two (2) parallel lines are cut through by a transversal:
m∠5 + m∠6 =180°.
What is the exterior angle property?The exterior angle property can be defined as a theorem which states that the measure of an exterior angle in a triangle is equal in magnitude to the sum of the measures of the two remote or opposite interior angles of that triangle:
m∠2 + m∠3 = m∠6.
In conclusion, the sum of all the angles formed by a triangle is equal to 180º:
