Evaluate the function when x= -3,0 and 1. Show work H(x) = 2.5x + 7

Answers

Answer 1

Answer:

H(-3)= -0.5

H(0)= 7

H(1)= 9.5

Step-by-step explanation:

For H(-3)

Substitute all of the x into -3

H(-3)=2.5(-3)+7

2.5 times -3 is -7.5

-7.5+7 is -0.5

So the answer for H(-3) is -0.3

For H(0)

Substitute all of the x into 0

H(0)=2.5(0)+7

2.5 times 0 is 0

0+7 is 7

So the answer for H(0) is 7

For H(1)

Substitute all of the x into 1

2.5(1)+7

2.5 times 1 is 2.5

2.5+7 is 9.5

So the answer for H(1) is 9.5

Hope this helps!

Ms. Dirr is selling her car to her sister. The original price of the car was $24,179 and
each year the car decreasing (goes down) by $3000. Write a function rule where C =
value of the car and y = number of years
O C = 3000 - 24179y
O C = 24179 - 3000y
O C = 3000 + 24179y
OC - 24179 + 3000y

Answers

Answer: 24,179 - 3000y

Step-by-step explanation: Each year the car goes down by 3000 since you said it was decreasing, so y represents the year and you eould out it next to the 3000 to represent that 3000 is being decreased every year.

Two numbers are co-prime if they have no common factors (other than
1). By drawing Venn diagrams or otherwise, decide whether each pair of
numbers is co- prime.
a) 105 and 429 b) 63 and 715 C) 121 and 175 d) 455 and 693

Answers

Answer:

See below.

Step-by-step explanation:

a)

105/3 = 35

35/5 = 7

7/7 = 1

429/3 = 143

143/11 = 13

13/13 = 1

105 = 3 * 5 * 7

429 = 3 * 11 * 13

Not co-prime

For the other parts of the problem, do the same I did above. Find the prime factorizations of both numbers, and see if they have any prime factors in common.

What is the rate of return when 35 shares of Stock A, purchased for $20/share, are sold for $815? The commission on the sale is $6. Rate of Return = [?] % Give your answer as a percent rounded to the nearest tenth​

Answers

Cost price:-

[tex]\\ \sf\longmapsto 35\times 20[/tex]

[tex]\\ \sf\longmapsto 700[/tex]

Commision=$6Total sold price=815+6=823$

Now

Return=823-700=123

Rate of return

[tex]\\ \sf\longmapsto \dfrac{123}{700}\times 100[/tex]

[tex]\\ \sf\longmapsto \dfrac{123}{7}[/tex]

[tex]\\ \sf\longmapsto 17.5\%[/tex]

The rate of return on the stock will be equal to 17.3%.

What is the Percentage?

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the given information in the question,

Total number of stocks = 35

Purchase price of each stock = $20

Then, the price of 35 stocks will be,

35 × $20 = $700

The selling price of all stocks = $815

Also, the commission for selling is $6.

So, the extra money earned will be,

815 - 700 + 6 = 115 + 6

= $121

So, the rate of return from the original price will be,

= 121/700 × 100

= 12100/700

= 17.3%

x over 32 = 3 over 16

Answers

Answer:

7/32 = 3/16

Step-by-step explanation:

Answer:

x=6

Step-by-step explanation:

We simplify the equation to the form, which is simple to understand

x/32=3/16

Simplifying:

+ 0.03125x=3/16

Simplifying:

+ 0.03125x=0.1875

We move all terms containing x to the left and all other terms to the right.

+ 0.03125x=0.1875

We simplify left and right side of the equation.

+ 0.03125x=0.1875

We divide both sides of the equation by 0.03125 to get x
