Answer:

Step-by-step explanation:

line parallel to given line has same slope i.e.,-5

eq. of line through (3,1) with slope -5 is

y-1=-5(x-3)

y-1=-5x+15

y=-5x+15+1

or y=-5x+16

Answer:

Equation of a line is y = mx + c

where

m = gradient

c = y intercept

y = -5x + 3

Comparing this equation with the above formula

m = - 5

Since the lines are parallel their gradients are also the same.

So gradient of the parallel line is also 5

That's m = -5

Equation of the parallel line using point

(3, 1) and gradient m = -5 is

y - 1 = -5(x - 3)

y - 1 = -5x + 15

y = -5x + 15 + 1

Final answer is

y = -5x + 16

Hope this helps.

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. If Hugh bought

DiKsa [7]

So first you want to find the price of all the magazines he bought which is 3.95 x 3 = 11.85.
then you are going to find out how much money he had left to spend on books which is 47.65-11.85=35.80

then you want to find how many books he bought with that money so you would take 35.80/8.95= 4

so he bought 4 books

suppose Tomas buys a total of 30 baseball and football cards in week 5 . how many of each would he have to buy to keep the same

Charra [1.4K]

Answer:

18 baseball cards
12 football cards

Step-by-step explanation:

The only relationship shown in the table is in week 1, where the ratio of baseball to football cards is ...

baseball : football = 9 : 6

In week 1, the total of these numbers is 15. You want the total in week 5 to be 30, double the total in week 1. So, Thomas needs to purchase double the numbers he purchased in week 1:

18 baseball cards
12 football cards

This table came from another question you posted, a question with no content other than the table. The blue numbers are blanks in the original table that have been filled in so as to keep the same 3:2 proportion in each week. They appear to have no bearing on this question.

What is the correct way to write this fraction as a percent? A. 20% B. 25% C. 40% D. 70%

Dimas [21]

20% as a fraction is 1/5

25% is 1/4

40% is 2/5

and 70% is 7/10

Depending on what your fraction is, you can find the answer in the fraction itself-

20%, you can take 20, 5 times to get to 100. Hence 1/5.

25 can go into 100 4 times (1/4)

40 is just 20 twice, so its 2/5.

Take 10 7 times and get 7/10.

Hope this helps a bit :)

Generally what do the elements in a group have in common with each other?

Tatiana [17]

They have the same number of valence electrons which, in general, gives them similar oxidation numbers and other similar chemical and physical properties. The similarities are most pronounced in the groups at either side of the standard periodic table, and are least pronounced for the transition and rare earth elements.
