Answer:
The constant of variation is k=5
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
[tex]y=k\cdot x[/tex]
Where k is the constant of proportionality.
We know R varies directly with S. Their relationship is:
[tex]R=k\cdot S[/tex]
We also have when S=16, R=80. Thus:
[tex]80=k\cdot 16[/tex]
Solving for k:
[tex]k=80/16=5[/tex]
The constant of variation is k=5

From Get Engaged! Part 1, if you thought that the monthly payment is the most important factor for Juan to consider, then you are correct. He should still consider the amount of interest that he will be paying, but if he can only pay a certain amount each month, he is not able to pick a payment plan based only on interest.
How can Juan compare the amount of interest of the two plans he has been presented with? Juan will need to multiply … _______________________________.
Great work! In order to find out how much Juan will pay in interst for each plan (3 years versus 5 years), we have to start by finding out how many months are in 3 years and 5 years. Since there are 12 months in one year, you can multiply 12 x 3 and 12 x 5.
PLAN 1: In the first plan, Juan pays $456 for 36 months. 456 x 36 = $16,416. The cost of the car is $15,000. In order to find the interest, we have to find the difference between the total amount that Juan would pay and the cost of the car: 16,416 - 15,000 = $1,416 in interest.
PLAN 2: In the second plan, Juan pays $289 for 60 months. 289 x 60 = $17,340. The cost of the car is $15,000. In order to find the interest, we have to find the difference between the total amount that Juan would pay and the cost of the car: 17,340 - 15,000 = $2,340 in interest.1) What is the benefit to paying a higher monthly payment for less time?
1) What is the benefit to paying a higher monthly payment for less time?
2) What is the benefit to paying a lower monthly payment for longer?
Answer: $450 i think. hope this
aking additional principal payments will shorten the length of your mortgage term and allow you to build equity faster. Because your balance is being paid down faster, you'll have fewer total payments to make, in-turn leading to more savings.
and the 2) because your monthly payments are lower on a loan with a longer repayment term, this gives you more wiggle room in your budget. You may need this extra cash to put towards other important goals.

Philip is going on a 400 mile road trip with three friends. He can travel 18 miles for every gallon of gas used. Gas costs $3.59 per gallon. If Philip and his friends want to split the cost of gas evenly, how much should each person pay?
Answer:
well divide the price of the gas by the three friends and you'll get your answer.
Answer:
$19.94 approx
Step-by-step explanation:
Divide 18 into 400, then take that number and multiply by 3.59. Take that answer and divide it by 4 since it's him +3 to get 19.94
what is the slope of the equation y=5/4x-7/4
Answer: x-intercept = 7/5 = 1.40000
y-intercept = -7/4 = -1.75000
Step-by-step explanation: Solve 4y-5x+7 = 0
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 4y-5x+7 = 0 and calculate its properties
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -1.750 and for x=2.000, the value of y is 0.750. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 0.750 - (-1.750) = 2.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 2.500/2.000 = 1.250

Figure 3

144 what is the angle measure in degrees for thr missing variable x in figure
The value of the angle x is equal to 98°.
Given that the figure attached below.
To find the angle x, follows sum steps as:
Draw one parallel line between the given parallel lines with intersect the point x.
By linear sum,
Angle 1 on below parallel line is 180° - 144° = 36°.
Angle 2 is equal to angle 1, that is, angle 2 is equal to 36°.
Angle 3 on centre parallel line is equal to 62°.
So, the angle x is calculated as:
x = Angel 2 + Angle 3
x = 36° + 62°
x = 98°
Hence, the required angle is equal to 98°.

What is the equation of the line that passes through the point (4, -8) and has a
slope of -1/2?
PLEASE HURRY !!
Answer:
y= -1/2x-6
Step-by-step explanation:
Write an equation in standard form of the line that passes through (4,−1) and has the slope m=3.
Answer :
m = 3
Point = (4,-1)
x1 = 4
y1 = -1
Formula =
y - y1 = m (x-x1)
y - (-1) = 3 (x -4)
y + 1 = 3x -12
y - 3x + 1 + 12 = 0
y - 3x + 13 = 0
The line = y - 3x + 13 = 0 or -3x + y + 13 = 0

y=3x-13 is the equation in standard form of the line that passes through (4,−1) and has the slope m=3.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
m=3
We need to find slope intercept form, for this we should know the y intercept with slope m =3 and point (4,-1)
-1=3(4)+b
-1=12+b
-1-12=b
b=-13
y intercept is -13
Hence, y=3x-13 is the equation in standard form of the line that passes through (4,−1) and has the slope m=3.

Is number 1 = 90 ?
Yes you are correct. The diagonals of any kite are perpendicular.
This can be proven by showing that triangle KGH is congruent to triangle KJH through the SSS congruence theorem. From there you break up the triangles focusing on triangle JRK and triangle GRK, now using the SAS rule to conclude that angle JRK = angle GRK. Since those are a linear pair, those angles must be right angles.
Side note: A kite is defined to be any quadrilateral in which it has two pairs of adjacent congruent sides. Not all four sides are the same length though (otherwise we would have a rhombus).
What is the equation of the line that passes through the point (-5, 2) and has a

Answer:
y - 2 = 4/5(x + 5)
Step-by-step explanation:
Well, the equation format your question is asking for is Point-slope form which is represented by:
[tex]y - y^{1} = m (x - x^{1})[/tex]
[tex]y^{1}[/tex] = y in point
[tex]x^{1}[/tex] = x in point
m = slope
Now, we have to input our values into our equation.
y - 2 = 4/5(x + 5)

Answer:
44 degrees
Step-by-step explanation:
Triangles ABC and DBC are congruent (as said in the question), that would make the corresponding parts of the two triangles congruent.
Answer:
Angle D = 44° (degrees)
Step-by-step explanation:
given that ∆ABC is congruent to ∆DBC, AB = 10, and Angle A = 44°. Angle D must be 44° as well since you can tell that angle abc is 88° and is not a right angle, and due to the corresponding parts. You can also think about these triangle as angles since angle abc = angle dbc. The other angles can be calculated using the triangle sum theorem since both triangles share side bc so angle acb and dcb are right angles(90°)
therefore 180-(44+90) = 46° which the measure of angles abc and dcb.
This measure would only make it true because of triangle congruency.

.3y + 3 (1 - y - y = 6
Answer:
sorry it's too long
Step-by-step explanation:
Simplifying
3y + 3(1 + -1y) + -1y = 6
3y + (1 * 3 + -1y * 3) + -1y = 6
3y + (3 + -3y) + -1y = 6
Reorder the terms:
3 + 3y + -3y + -1y = 6
Combine like terms: 3y + -3y = 0
3 + 0 + -1y = 6
3 + -1y = 6
Solving
3 + -1y = 6
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + -1y = 6 + -3
Combine like terms: 3 + -3 = 0
0 + -1y = 6 + -3
-1y = 6 + -3
Combine like terms: 6 + -3 = 3
-1y = 3
Divide each side by '-1'.
y = -3
Simplifying
y = -3
