Answer:

$1800 and $2500

Step-by-step explanation:

Let he invested a total of  $P and$( P+700) in each investment so according to question

9.2*P*1+10.4*(P+700)*1= 42560

19.6P+ 7280= 42560

19.6P = 42560-7280= 35280

P=$ 1800

So, he invested $1800 and $2500 respectively.

WILL GIVE BRAINLIEST! Someone please graph these, I can't graph them.
nadezda [96]

Answer:

see attached image

Step-by-step explanation:

F(x) = 2x + 5 is a linear graph because the exponent on x is 1.  I tell my students that think of graphs having one less turn/corner that the value of the highest exponent.  so since 2x has a exponent of 1, 1-1 =0 so it has no turns or its a straight line.

this has a slope of 2 or 2/1 or up 2 and right 1 from the y intercept which is 5

so mark 5 on the y axis and a from there go up 2 and right 1 and make another point.  Join these points and you have your graph


and


g(x) = (x-5)/2  is its inverse and is found:

F(x) = 2x + 5 write it this way y = 2x + 5

now swap the x and y    x = 2y - 5

solve for y

x = 2y + 5

- 5       -5

x - 5 = 2y

/2        /2

(x-5)/2 = y

it can be written as y = x/2 - 5/2

and graphed the same way as above with a  1/2 slope and -5/2 y intercept

At a store, customers are randomly selected to participate in a survey. On Friday, there were 500 customers at the store. Out of
Svetlanka [38]
Divide the number of people selected by the total number of people.

90/500 = .18

This means that 18% of the customers were selected for the survey.

If the probability is the same on Saturday, then we can multiply the expected customers by our .18

700 x .18 = 126

126 should be selected for the survey on Saturday.
