(7,2) and has a slope of

1?

Answers

Answer:

(y+2)= -3(x-7)

Step-by-step explanation:

We can use the slope-intercept formula to write this equation. The slope-intercept form of a linear equation is:  

y = m x + b

 Where  m  is the slope and  b  is the y-intercept value.

We can substitute the slope into the formula giving:

y = − 3 x + b

Next, we can substitute the values from the points in the problem for  x  and  y  and solve for  b :

− 2 = ( − 3x 7 ) + b  

− 2 =  − 21 + b

21 − 2 = 21  − 21 + b

 19 = 0 + b

19 = b

We can now substitute the slope from the problem and the value for  b  we calculated into the formula to write the equation.

y = − 3 x + 19

Another process is to use the point-slope formula. The point-slope formula states:

 ( y − y 1 ) = m ( x − x 1 )

 Where  m  is the slope and  ( x 1 , y1 )  is a point the line passes through.

Substituting the slope and values from the points in the problem gives:

(y − − 2 ) = − 3 (x-7)

( y + 2 ) =  − 3 ( x − 7 )

1. Let the side length of each small square on the grid represent 1 unit. Draw two different triangles, e. Ach with base 5 1/2 units and area 19 1/4 units2. 2. Why does each of your triangles have area 1914 units2?

Answers

Answer:

Step-by-step explanation:

Given that:

Each small square on a grid represents 1 unit

Base of triangle = 5 1/2 units = 11/2

Area of triangle = 19 1/4 unit² = 77/4

The Area, A of a triangle is obtained thus :

77/4 = 1/2 * 11/2 * h

77/4 = 11/4 * h

h = 77/4 ÷ 11/4

h = 77/4 * 4 /11

h = 7 units

Use the Pythagorean theorem to obtain the function​ D(x) for the length of the diagonal of a double square of width x.

Answers

Answer:

[tex]D(x)= x\sqrt{2}[/tex]

Step-by-step explanation:

Given

[tex]Side = x[/tex]

Required

Represent the diagonal as a function

Using Pythagoras theorem, the diagonal is:

[tex]D^2= Side^2 + Side^2[/tex]

Substitute x for Side

[tex]D^2= x^2 + x^2[/tex]

[tex]D^2= 2x^2[/tex]

Take the square root of both sides

[tex]D= \sqrt{2x^2[/tex]

Split

[tex]D= \sqrt{2} * \sqrt{x^2[/tex]

[tex]D= \sqrt{2} * x[/tex]

[tex]D= x\sqrt{2}[/tex]

Express as a function.

[tex]D(x)= x\sqrt{2}[/tex]

A postcard has a perimeter of 20 inches. Its area is 21 square inches. What are the dimensions of the postcard?

Answers

Answer:

Length = 3 inches

Width = 7 Inches

Step-by-step explanation:

The shape of a postcard = Rectangle

L = Length

W = Width

A postcard has a perimeter of 20 inches.

Formula for perimeter of a rectangle = 2L + 2W

Hence:

2L + 2W = 20.... Equation 1

Its area is 21 square inches.

The formula for Area of a rectangle = LW

Hence:

LW = 21

L = 21/W

We substitute 21/W for L in Equation 1

2L + 2W = 20.... Equation 1

2(21/W) + 2W = 20

42/W + 2W = 20

Multiply both sides by W

42 + 2W² = 20W

2W² - 20W + 42 = 0

2W - 14W - 6W + 42 = 0

(2W - 6)( W - 7) = 0

2W - 6 = 0

2W = 6

W = 6/2 = 3

W - 7 = 0

W = 7 inches

Solving for L

L = 21/W

W = 7

L = 21/7

L = 3 inches

The dimensions of the postcard are:

Length = 3 inches

Width = 7 Inches

The area of the flower bed is equal to 6 square feet.


The area of the flower bed is smaller than 6 square feet.

Answer is D, the area of the flower bed is smaller than 6 feet.

6 times 6/8 will be 36/8, which is also 4 4/8. That’s smaller than 6 feet, so your answer is D

If you can help me with Slope Intercept plz help me

Answers

Answer:

y = 6/5x - 2 (or y = 1.2x - 2)

Step-by-step explanation:

To find the slope-intercept form ( = mx + b) you need to rearrange the equation of the line:

Step 1 - Add 18x to both sides

15y = 18x - 30

Step 2 - Divide both sides by 15.

y = 6/5x - 2

solve the right triangle (45-45-90)

Answers

Answer:

[tex]HI=HJ=\sqrt{30}[/tex]units

[tex]\angle I=45^{\circ}[/tex]

Step-by-step explanation:

We are given that

[tex]\angle J=45^{\circ}[/tex]

[tex]JI=2\sqrt{15}[/tex]units

We know that

[tex]sin\theta=\frac{Perpendicular\;side}{hypotenuse}[/tex]

Using the formula

[tex]sin45=\frac{HI}{2\sqrt{15}}[/tex]

[tex]\frac{1}{\sqrt{2}}\times 2\sqrt{15}=HI[/tex]

Where [tex]sin45^{\circ}=\frac{1}{\sqrt{2}}[/tex]

[tex]\frac{2\sqrt{15}\times \sqrt{2}}{\sqrt{2}\times \sqrt{2}}=HI[/tex]

By using rationalization

[tex]HI=\sqrt{30}[/tex] units

[tex]Cos45=\frac{HJ}{2\sqrt{15}}[/tex]

Using the formula

[tex]cos\theta=\frac{base}{hypotenuse}[/tex]

[tex]\frac{1}{\sqrt{2}}\times 2\sqrt{15}=HJ[/tex]

[tex]\frac{2\sqrt{15}\times \sqrt{2}}{\sqrt{2}\times \sqrt{2}}=HJ[/tex]

[tex]HJ=\sqrt{30}[/tex] units

When two sides are equal then angle made by two equal sides are equal

Therefore,

[tex]\angle J=\angle I=45^{\circ}[/tex]

A spaceship to the moon covered the 386,400 km in 72 hours. What was the average speed?

Answers

Answer:

289300 miles/72 hours * 1.60934 km/mile* 1 hour/3600 seconds = 1.48 km/second. Answer 6: To get average speed, we divide the total distance by the total time it takes to travel that distance. If we assume the distance to the moon is 238,900 miles then we divide by 72 hours to get roughly 3318 mph.

The measures of the angles of a triangle are shown in the figure below. Solve for x.

Answers

Answer:

Step-by-step explanation:

x=180-59-41

x=80

Answer: 80°

Step-by-step explanation:

The sum of all angles in a triangle is always 180°

so 59° + 41° + x ° = 180°

or x = 180 - 41 - 59 = 80

abdel purchased a candy bar for $1.47 and ice cream for $3.48. How much change did he receive if he paid a ten-dollar bill.

Answers

1.47+3.48=4.95
10-4.95=5.05
Answer:
$5.05 is the change Abdel will receive if paid by a ten dollar bill.


Candy bar price plus ice cream price = the total amount / $3.48 + $1.47 = $4.95
Ten dollar bill subtracted by the total amount = the change / $10 - $4.95 = $5.05

Can the measure of an exterior angle of a triangle ever exceed 180°? Explain your reasoning.​

Yes I believe so because the interiors of a triangle always add up to 180 degrees meaning the outside mustn't follow this same rule hop this helps!

Step-by-step explanation:

Answer:

Lets assume you have a triangle ABC with a straight horizontal line at the bottom say line segment CD. In order for the exterior angle to be greater than 180 it must be a exceed rad Pi which mean it is impossible for an exterior angle to exceed the 180 rule

June was thinking of a number. June subtracts 5.6 from the number and gets an answer of 76.9. Form an equation with x from the information.

Answers

Answer: x - 5.6 = 76.9

Step-by-step explanation:

The number June thought of would give a result of 76.9 if 5.6 were subtracted from it.

Assume that number is x.

If you subtract 5.6 from x, you would get 76.9.

Equation is therefore:

x - 5.6 = 76.9

Solving for x would make x:

x - 5.6 = 76.9

x = 76.9 + 5.6

x = 82.5

Answers

Answer:

1. 23.8

2. 7.7

Step-by-step explanation:

for the first blank

use sin because x is opposite and 25 is hypotenuse

set up an equation:

sin(72)= (x/25)

multiply both sides by 25:

25(sin(72))= (x/25)25

25(sin(72))= x

multiply 25 by sin(72):

23.8 = x

for the second blank

use cos because x is adjacent and 25 us hypotenuse

set up an equation:

cos(72)= (x/25)

multiply both sides by 25:

25(cos(72))= (x/25)25

25(cos(72))= x

multiply 25 by cos(72):

7.7= x
