write the equation for this line in slope intercept form

Answers

Answer:

y = [tex]\frac{3}{2}[/tex]x + 2

Step-by-step explanation:

Slope-intercept form is y = mx + b with m as the slope and b as the y-intercept.

The y-intercept is the point where the line intersects the y- axis.

y = mx + 2

The equation to find slope is [tex]\frac{y1-y2}{x1-x2}[/tex]       Two points from the line: (0,2) (4,8)

[tex]\frac{8-2}{4-0}[/tex] = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]

y = [tex]\frac{3}{2}[/tex]x + 2

Parvinder wants to save $500 for a trip. Which inequality shows the least amount she must save each month for 6 months to accomplish this?

A 6x 500 B 6x > 500 C 6x => 500 D x => 500 + 6

Answers

Answer:

The correct answer is C. 6x = 500.

Step-by-step explanation:

In this expression, the "x" represents how many dollars he needs to save every month. Or in other words, the amount of money he earns a month multiplied by the amount of months should equal 500 in order for Parvinder to be able to go on his trip.

Therefore, the correct answer is C. 6x = 500.

The amount of time it takes a water pump to empty a tank varies directly as the capacity of the tank. If it takes a water pump 2.5 hours to empty a tank containing 60,000 gallons of water, how long does it take the same pump to empty a tank containing 108,000 gallons of water?

Answers

Answer: 4.5 hours

Step-by-step explanation: i used cross multiplication.

2.5/x=60,000/108,000

60,000x=270,000

divide 270,000 by 60,000

x=4.5

An equation is formed when two equal expressions. The time the same pump will take to empty a tank containing 108,000 gallons of water is 4.5 hours.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that the amount of time it takes a water pump to empty a tank varies directly with the capacity of the tank. Therefore, the relationship can be written as,

V ∝ T

V = kT

Substituting the volume and time in the equation,

60,000 gallons = 2.5 hours × k

Solving the equation for k,

k = 60,000 gallons / 2.5 hours

k = 24,000 gallons per hour

Now, the equation for the relationship can be written as,

V = 24,000 gallons per hour × T

Now, the time the same pump will take to empty a tank containing 108,000 gallons of water is,

V = 24,000 gallons per hour × T

108,000 gallons = 24,000 gallons per hour × T

108,000 gallons / 24,000 gallons per hour = T

T = 4.5 hours

Hence, the time the same pump will take to empty a tank containing 108,000 gallons of water is 4.5 hours.

Answers

Given:

The graph of an inequality.

To find:

The inequality for the given graph.

Solution:

From the given graph it is clear that the related line is a vertical line parallel to the y-axis at a distance of 7 units from the left of y-axis. It intersect the x-axis at x=-7.

So, the related equation for boundary line is

[tex]x=-7[/tex]

The shaded region is on the left side of the boundary line. it means, the value of x which are less than -7 are included in the solution set.

The boundary line is a solid line. It means -7 is also included in the solution set.

The value of x is less than or equal to -7. So, the inequality for shaded region is

[tex]x\leq -7[/tex]

Therefore, the correct option is B.

Find sin theta if cot theta = -2 and cos theta < 0

Answers

cot(θ) = cos(θ)/sin(θ)

So if both cot(θ) and cos(θ) are negative, that means sin(θ) must be positive.

Recall that

cot²(θ) + 1 = csc²(θ) = 1/sin²(θ)

so that

sin²(θ) = 1/(cot²(θ) + 1)

sin(θ) = 1 / √(cot²(θ) + 1)

Plug in cot(θ) = -2 and solve for sin(θ) :

sin(θ) = 1 / √((-2)² + 1)

sin(θ) = 1/√(5)

How to find the set of ordered pairs?

Here we know that the sloth travels about 7 feet every minute, then we can define the speed as:

S = 7 ft/min

Now remember the relation:

distance = speed*time

Then the proportional relation is:

D = 7*t

The ordered pairs are of the form (t, D)

if t = 1.

D = 7*1 = 7

if t = 2

D = 7*2 = 14

if t = 3

D = 7*3 = 21

if t = 4

D = 7*4 = 28

Then the 4 ordered pairs are (1, 7), (2, 14), (3, 21), (4, 28).

the midpoint of AB is M (4,0). if the coordinates of A are (3, 1), what are the coordinates of B?

Answers

The coordinates of point B are (5, -1) if the midpoint of AB is M(4, 0) and the coordinates of A are (3, 1).

Let the coordinates of point B are (x, y).

According to the give question.

The midpoint of AB is M(4, 0).

The coordinates of A are (3, 1).

Therefore, the coordinates of points B are given by

(4, 0)  = ( (3 + x)/2,  (1 + y)/2)

⇒ (3 + x)/2 = 4, and (1 + y)/2  = 0

⇒ 3 + x = 8 and 1 + y = 0

⇒ x = 8 - 3   and   y = -1

⇒ x = 5 and y = -1

Hence, the coordinates of point B are (5, -1) if the midpoint of AB is M(4, 0) and the coordinates of A are (3, 1).

Which ordered pair is a solution of the equation y=5x? (-2, 10) (-5, 25) (-3, 15) (-2, 10)

Answers

One of the solutions of the given equation y = 5x is (2,10)

The solution of an equation means if we substitute the value of this solution into the equation, it will produce the correct equality from the left side to the right side.

If the solution has 2 variables, for example x and y, and the solution is (a,b) means that if we replace x with a and y with b, the equality is correct.

The given equation is: y = 5x

For option (-2,10), substitute x = -2 and y = 10 into the equation:

10 = 5 . (-2)

10 = -10 (False)

Hence (-2,10) is not a solution.

For option (-5, 25), substitute x = -5 and y = 25 into the equation:

25 = 5 . (-5)

25 = -25 (False)

Hence (-5, 25) is not a solution.

For option (-3, 15), substitute x = -3 and y = 15 into the equation:

15 = 5 . (-3)

15 = -15 (False)

Hence (-3, 15) is not a solution.

There is no options in the problem that gives the correct equality. Looks like there is a typo.

Example of a solution of the given equation is (2,10), since if we substitute x = 2 and y = 10 into the equation:

10 = 5 . (2)

10 = 10 (True)

Hence (2, 10) is a solution.

Use the definition of congruence to decide whether the two figures are congruent
Someone help please

Answers

Answer:

These two figures are not congruent.

Step-by-step explanation:

The definition of congruence is, "In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.", now knowing this we next take a look at the figures.

Coordinates (A, E) do not match up with the bottom figures (P, T). The next coordinates (E, D) also don't match up with coordinates (T, S). Coordinates (A, B) and (P, Q) don't match up together either. (B, O), (Q, R), (O, D), or (R, S) also do not match up if you look closely at them. Now you can conclude that although these two figures may look alike at first glance, their points are put in different places showing that they aren't the same in shape and size; meaning they are not congruent.

Two figures are congruent if their dimensions are equal

ABCDE = PQRST therefore, ABCDE ≅ PQRST, by the definition of congruency

Reason:

The coordinates of pentagon ABCDE are;

A(-2, 8), E(4, 8), D(6, 2), C(-2, 2), B(-4, 6)

The coordinates of pentagon PQRST are;

P(-3, 0), T(3, 0), S(5, -6), R(-3, -6), Q(-5, -2)

By performing the vector translation of [tex]\dbinom {1}{8}[/tex], to PQRST, we have;

P(-3 + 1, 0 + 8) = (-2, 8) = Coordinates of A

T(3 + 1, 0 + 8) = (4, 8) = Coordinates of E

S(5 + 1, -6 + 8) = (6, 2) = = Coordinates of D

R(-3 + 1, -6 + 8) = (-2, 2) = = Coordinates of C

Q(-5 + 1, -2 + 8) = (-4, 6) = = Coordinates of B

Given that a translation is a rigid transformation and  that by performing a translation transformation of [tex]\dbinom {1}{8}[/tex], on PQRST gives ABCDE, we have that the dimensions of the pentagon ABCDE = The dimensions of the pentagon PQRST, we have;

ABCDE = PQRST

Therefore;
