Write the equation of the line described:
18. Slope 2, y-intercept is -4
(Show answer in slope-intercept form.)
Answers
y = 2x - 4
Step-by-step explanation:
Slope = 2, y-intercept = -4
The equation of the line is y = 2x - 4
Slope-intercept Form: y = mx + b where m = slope and b = y-intercept
Therefore, the equation of the line is y = 2x - 4

Answers
Hey there! I'm happy to help!
A quadrilateral is any polygon (enclosed shape) with four sides. Let's see what each of these shapes are.
Scalene right triangle - the prefix tri- means three (tricycle, tripod, triple, etc.), and all triangles have three sides, so this is not a quadrilateral.Obtuse scalene triangle - once again a triangle, so not a quadrilateral.Isosceles right triangle - would you look at that, another triangle! Not a quadrilateral.Hexagon - a hexagon is a six-sided polygon (hex=six), so this is not a quadrilateral.Pentagon - a pentagon is a five-sided polygon (pent=five, like Pentatonix!). Not a quadrilateralRight trapezoid - a trapezoid is a quadrilateral with at least one pair of parallel sides!Venn diagram - a Venn diagram is a compare and contrast chart made of two overlapping circles (ZERO sides), so this is not a quadrilateral.So, the only shape on your list that is a quadrilateral is 6. right trapezoid.

Last month, a printing company printed $56,000.00 worth of books. This month, they printed $63,000.00 worth of books. What is the percent increase in their printing?
Answers
Explanation:
56000 • x% = 63000
56000 • x/100 = 63000
56000x = 6,300,000
x = 6,300,000/56,000
x = 112.5%
x - 100 = 112.5% - 100% = 12.5%

Exercise "position and instantaneous velocity"
(Full development)
Answers
(A) The blue line has a slope of 5/2, red has slope 4/4 = 1, and purple has slope 3/9 = 1/3.
To find the slope, take any two points (a, b) and (c, d) on the line, then
slope = (d - b)/(c - a)
i.e. the ratio between the changes in the y and x coordinates.
(B) Each line has equation
• blue: y = 5/2 x
• red: y = x
• purple: y = 1/3 x
This follows from the general equation for a line with slope m and y-intercept b,
y = mx + b
or from the more general equation for a line with slope m passing through a point (a, b),
y - b = m (x - a)
(C) Consider the blue line. If you take units into account, its slope is
(5 units of distance)/(2 units of time) = 5/2 (units of distance/time)
which means, per unit time, some object travels a 5/2 units of distance, and this is the definition of speed.
(D) The competitor with the blue line, Mary, would win the race because their speed is the highest (5/2 > 1 > 1/3).
(E) Average velocity is defined as
v (ave) = ∆d/∆t = (change in distance)/(change in time)
At time 0, no one has moved yet. At time 4,
• Mary has covered a distance of 5/2 × 4 = 10, giving her an average velocity of (10 - 0)/(4 - 0) = 5/2
• Mike has covered a distance of 4, so his average velocity is (4 - 0)/(4 - 0) = 1
• Sam has covered a distance of 1/3 × 4 = 4/3, so his average velocity is (4/3 - 0)/(4 - 0) = 1/3
It's not a coincidence that the average velocities are the same as the slopes, because each racer travels at a constant speed.
(F) The racers' instantaneous velocities are the same as their respective average velocities, again because they are each moving at a constant speed.

2. Not Divisible
3. Divisible
4. Divisible
5. Divisible
6. Not Divisible
7. Divisible
Step-by-step explanation:
Question 2. Is 629,257 divisible by 5?
- Numbers that are divisible by 5 should end with either 5 or 0.
- The ending term of [629,257] is 7, which is neither 5 nor 0. Therefore, it is not divisible.
Question 3. Is 3,791,916 divisible by 2?
- Numbers that are divisible by 2 should end with an even number or 0, which include 0, 2, 4, 6, 8.
- The ending term of [3,791,916] is 6, which is an even number. Therefore, it is divisible.
Question 4. Is 63,726,125 divisible by 5?
- Numbers that are divisible by 5 should end with either 5 or 0.
- The ending term of [63,726,125] is 5. Therefore, it is divisible.
Question 5. Is 486,342 divisible by 3?
- In numbers that are divisible by 3, the sum of all digits is a multiple of 3.
- The sum of all digits of [486,342] is [4 + 8 + 6 + 3 + 4 + 2 = 27].
- 27 / 3 = 9
- Since the sum of all digits is divisible by 3, then 486,342 is divisible by 3.
Question 6. Is 474,493 divisible by 10?
- Numbers that are divisible by 10 should end with 0.
- The ending term of [474,493] is 3, which is not 0. Therefore, it is not divisible.
Question 7. Is 53,017,587 divisible by 9?
- In numbers that are divisible by 9, the sum of all digits is a multiple of 9.
- The sum of all digits of [53,017,587] is [5 + 3 + 0 + 1 + 7 + 5 + 8 + 7 = 36].
- 36 / 9 = 4
- Since the sum of all digits is divisible by 9, then 53,017,587 is divisible by 9.

Answer:
C
Step-by-step explanation:
this is a "translation" - a shift of the object without changing its shadow and size.
this shift is described by a "vector" - in 2D space by the x and y distances to move.
we have here (1, 0) - so, we move every point one unit to the right (positive x direction) and 0 units up/down.
therefore, C is the right answer (the x coordinates of the points are increased by 1, the y coordinate are unchanged).

Solve the following proportion for y
y/9=13/11
Round your answer to the nearest tenth.
y=?
Answers
Answer:
y = 10.6
Step-by-step explanation:
We can solve using cross products
y 13
---- = ----
9 11
y*11 = 9*13
11y =117
Divide each side by 11
11y/11 =117/11
y=10.63636
To the nearest tenth
y = 10.6
The value of y using the proportion relation y/9 = 13/11 is 117/11.
Given Relation:
y/9 = 13/11
As, the proportion is the condition where two ratios are equivalent.
Now, solving the equation y/9 = 13/11 for y
First, cross multiply the equation
11y = 117
Now, divide both side by 11 gives
11y /11 = 117/ 11
y= 117 /11
As, there no common factor of 117 and 11.
Thus, the simplified value is 117.11
