A line that passes trough the point (7,3) with slope of -1 ( answer plesse I need help )

Answers

Answer:

Slope-Intercept Form:

The equation of a line in slope-intercept form is y=mx+b. Since we know that the slope is -1, the equation so far is y=-x+b. To find the value of b, substitute in the given point.

3=-7+b

Add 7 to both sides.

10=b

The equation of the line is slope intercept form is y=-x-10.

Point-Slope Form:

The equation of a line in point-slope form is y-y1=m(x-x1). Substituting in the given point and slope, the equation is y-3=-(x-7).

Hope this helps! :)

Answer:

y= -x + 10

Step-by-step explanation:

3 = -1(7) + b

3 = -7 + b

10 = b

Since the slope is -1, that means it's just -x

So y = -x + 10

Answer:

x = 115°

Step-by-step explanation:

The two angles are vertical, so x = 115°

Vertical Angles:

Vertical Angles are two angles formed by the intersection of two lines. Angles that are non-adjacent to each other are congruent in degrees.

We can see that 115° and x° are formed by the intersection of two lines, and they are non-adjacent (don't share a common side) which makes them congruent in degrees.

x = 115°

Answer:

1. 120 min

2. 25 cm

3. $6.84

Step-by-step explanation:

1. 120 words : 3min

multiply each side by 40 because 120 words times 4 is 4800 words

4800 words : 120min

2.   2 : 1 = length : width

multiply each side by 25 because 2 times 25 is 50 cm

50 cm : 25 cm

3. $1.14 : 100 grams

multiply each side by 6 because 100 grams times 6 is 600 grams

$6.84 : 600 grams

The equation
N(t) = 400/1 + 39e−0.7t models the number of people N in a town who have heard a rumor after t days.

How many people started the rumor?

Answers

Functions can be represented as equations, and equations can be represented as functions.

The number of people that started the rumor is 10

The function is represented as:

[tex]\mathbf{N(t) = \frac{400}{1 + 39e^{-0.7t}}}[/tex]

To calculate the number of people that started the rumor, we simply set t to 0.

So, we have:

[tex]\mathbf{N(0) = \frac{400}{1 + 39e^{-0.7 \times 0}}}[/tex]

Evaluate the exponent of e

[tex]\mathbf{N(0) = \frac{400}{1 + 39e^{0}}}[/tex]

Express e^0 as 1

[tex]\mathbf{N(0) = \frac{400}{1 + 39\times 1}}[/tex]

Multiply 39 and 1

[tex]\mathbf{N(0) = \frac{400}{1 + 39}}[/tex]

Add 1 and 39

[tex]\mathbf{N(0) = \frac{400}{40}}[/tex]

Divide 400 by 40

[tex]\mathbf{N(0) = 10}[/tex]

When t = 0, N(t) = 10

This means that 10 people started the rumor.

Hence, the number of people that started the rumor is 10

express the function graphed on the axes below as piecewise function

for x<-4
for x>2

Answers

Answer:

<--------o           o------------->

         -4           2

Step-by-step explanation:

Because the sign in the inequalities is only greater than/ less than (not equal to), we know that there is an open dot on x=-4 and on x=2.

From there, we shade the area on the graph that is true to the function.  So, we can test points.

First we will test x=-5

-5<-4  --> this is true, so we will shade to the left of x=-4

Now test x=0

0<-4  --> this is false

0>2  --> this is also false, so the area between the two open dots will not be shaded

Now test x=3

3>2  --> this is true, so we will shade to the right of x=3

Aaliyah is deciding between two parking garages. Garage A charges an initial fee of $8 to park plus $2 per hour. Garage B charges an initial fee of $4 to park plus $3 per hour. Let AA represent the amount Garage A would charge if Aaliyah parks for tt hours, and let BB represent the amount Garage B would charge if Aaliyah parks for tt hours. Graph each function and determine the interval of hours parked, t,t, for which Garage A is cheaper than Garage B.

Answers

The interval of hours for which Garage A is cheaper than Garage B is t > 4.

Let A represent the amount Garage A would charge if Aaliyah parks for t hours, and let B represent the amount Garage B would charge if Aaliyah parks for t hours.

Garage A charges an initial fee of $8 to park plus $2 per hour. Hence:

A = 2t + 8  

Garage B charges an initial fee of $4 to park plus $3 per hour. Hence:

A = 3t + 4

For Garage A to be cheaper than Garage B:

2t + 8 < 3t + 4

8 - 4 < 3t - 2t

4 < t

t > 4

The interval of hours for which Garage A is cheaper than Garage B is t > 4.

Answers

Answer: 24 in, 41 in

Step-by-step explanation:

Set shorter piece is x in, and another longer one is y.

1. x + y = 65

2. y = 2x - 7

plug in the second equation into y of the first equation, we get:

x + (2x - 7) = 65

x + 2x - 7 = 65

    3x - 7 = 65  (Add 7 to the both side)

          3x = 72     (Divide 3 to both side)

            x = 24 in

Plug x in the second equations to slove y.

y = 2x - 7

y = 2(24) - 7

y = 41 in

Wisdom means the ability to choose from what is available to us and then use it for our own benefit. Today, the world has started talking about the value based education. What does it mean? In simple terms it means two things. First, it accepts that current education has badly let down. Secondly, it lays stress on values, and hence wisdom, instead of mere knowledge. How do we acquire this value based education? The answer becomes simple if we need education. We need education only to make us live better and more joyously. Once we know this we must add only those things in education which achieve this aim. The dictum that a healthy mind can exist only in a healthy body is a time tested one. Schools, thus become sources of healthy bodies too. This can best be achieved by yoga because games are beyond our financial capabilities. Yoga is very beneficial.
