write the slope intercept form of the equation of each line

Answers

Answer:

Y= - 1/5x-4

Step-by-step explanation:

slope intercept form: y=mx+b

Slope formula: rise/run

(5,-5) AND (0,-4)

-5+-4= -1

5+0= 5 AKA - [tex]\frac{1}{5}[/tex] or -1/5

The m in y=mx+b is the slope, the equation above is the sloe formula meaning -1/5 is the slope. The b is the y, when it is at 0. The y at 0 for this equation is -4. Thus, when plugging in the equation, y=-1/5x-4

Lamont’s grandmother started a stamp collection in 1914 (year 1) and added the same number of stamps to the collection each year. When Lamont’s mother received the collection in 1954, there were 203 stamps in the collection. Lamont’s mother continued to add the same number of stamps to the collection each year. When Lamont received the collection in 1990, there were 383 stamps in the collection. If Lamont continued to add the same number of stamps each year, how many stamps were in the collection at the end of 2000 (year 86)?

A. 204

B. 293

C. 433

D. 663

Answers

Answer: C. 433

Step-by-step explanation:

Linear equation: y=mx+c, where m= constant rate of change, c=initial value of yor y-intercept.

Let x = number of years after 1914.

y= Number of stamps after x years.

In 1954 (year 40), there were 203 stamps in the collection.

i.e. 203=40m+c (i) [rate of change in number of stamps is constant]

In 1990 (year 76), there were 383 stamps in the collection.

i.e. 383=76m+c (ii)

Subtract (i) from (ii)

180= 36m

[tex]\Rightarrow\ m=5[/tex] i.e. 5 stamps added per year.

from (i), [tex]203=40(5)+c\Rightarrow\ c=203-200=3[/tex] [Initially he has 3 stamps]

Stamps in 2000(year 86) = m(86)+c= 5(86)+3

= 430+3

= 433

Hence, correct option is C. 433

Answers

Answer:

AB ≈ 8.86 cm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin41° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{13.5}[/tex] ( multiply both sides by 13.5 )

13.5 × sin41° = AB , then

AB ≈ 8,86 cm ( to 3 significant figures )

Answer:

8.87

Step-by-step explanation:

use the sin law for right triagles sin(θ)= opposite/hypotenuse so

sin(41)=(AB)/13.5

13.5×sin(41)=AB

8.87=AB

Shawn designs a rectangular garden as shown below. He will design both rock sections to have the same width (x).

The area in, square feet, of Shawn’s garden is found be calculating 15(2x + 7). Shawn incorrectly says the area can also be found using the expression 30x + 7.

Describe the error in Shawn’s expression. As part of your explanation, find the difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression.

Answers

Answer:

a) Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7

b) The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as

98 square feet

Step-by-step explanation:

The area in, square feet, of Shawn’s garden is found be calculating 15(2x + 7). Shawn incorrectly says the area can also be found using the expression 30x + 7.

The correct area =

15(2x + 7).

= 30x + 105 square feet

The error in Shawn’s expression is

= 15(2x + 7)

= 30x + 7 square feet

Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7

The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as

30x + 105 square feet - 30x + 7 square feet

= 30x + 105 - (30x + 7)

= 30x - 30x + 105 - 7

= 98 square feet

Conver Mixed Number to an Improper Fraction
15 and 7/10

Answers

Answer:157/10

Step-by-step explanation:

Make 15 into an improper fraction (every number is a fraction over 1) so multiply the numerator(15) and the denominator(1) by 10 to get 150/10 then add 150/10 to 7/10 to get 157/10

Answer:

[tex]\frac{157}{10}[/tex]

Step-by-step explanation:

Step 1

Multiply the denominator by the whole number

10 × 15 = 150

Step 2

Add the answer from Step 1 to the numerator

150 + 7 = 157

Step 3

Write answer from Step 2 over the denominator [tex]\frac{157}{10}[/tex]

A quadrilateral has three angles that measure 88°, 82°, and 55°. Find the unknown angle measure.

Answers

135 hope this helps :))

Answer: 135° is the unknown angle measure.

Step-by-step explanation: We know a quadrilateral has 4 angles and measure a total of 360°.

To find the unknown angle simply add all the 3 angles and then subtract them from 360°.

Follow the steps:

88° + 82° + 55° = 225°. (Added the 3 angles)

360° - 225° = 135°. (Subtract the sum of the 3 angles from 360 degrees)

A glass vase factory recently produced 4 vases that were chipped and 16

Answers

Answer:

Step-by-step explanation:

4 / 20 = 1/5 or 20% chance that vase will be chipped

Set up a proportion or find 20% of 10.

[tex]\frac{1}{5} = \frac{x}{10}[/tex] x = 2 (ten is on denominator because it's the total amount of vases)

Work out the value of d.

May someone help me pleaseeee

Answers

Answer:

c=2, d=16

Step-by-step explanation:

The value of c is 2 and value of d is 16 when f(x) = 2x + c, g(x) = cx + 7 and fg(x) = 4x + d

What is a function?

A relation is a function if it has only One y-value for each x-value.

Given,

f(x) = 2x + c...(1)

g(x) = cx + 7..(2)

fg(x) = 4x + d..(3)

We need to find the values of c and d

fg(x) = 2(cx+7) + c

Apply distributive property

fg(x) =2cx+14+c...*

Now compare * with equation 3

2cx=4x

2c=4

Divide both sides by 2

c=2

and 14+c=d

Substitute c in above equation

14+2=d

d=16

Hence, the value of c is 2 and value of d is 16 when f(x) = 2x + c, g(x) = cx + 7 and fg(x) = 4x + d
