Help me please I need the answer ASAP

Mathematics
1 answer:
ozzi3 years ago
8 0

a

10.95x + 2.50, but for eight books so 10.95 x 8 + 2.50 = 90.10

b

12.50x + 4.50, but for six books so 12.50 x 6 + 4.50 = 79.50

c

To do this, we can set them both equal to each other and if x is a whole number of books, then they do pay the same amount. If x is a decimal, then they don't pay the same amount.

10.95x + 2.50 = 12.50x + 4.50

2.50 - 4.50 = 12.50x - 10.95x

-2 = 1.55x

This can never be a whole number, so therefore members and non-members can never pay the same amount for an order of x books.

I really need help on this question! Thank you!
KIM [24]

Answer:

A

Step-by-step explanation:

We know the following:

OE=5\\\\FG=4\\\\EF=8\\\\

so the segment EF is equal to

EF=EG+GO+OF\\\\

and here we can do a trick :)

EF=(EG+GO)+GO+(OF+OG)-2GO\\\\

you see it's the same

EF=EO-GO+FG\\\\

now we plug the values given

8=5-GO+4\\\\8=9-GO\\\\GO=9-8\\\\GO=1

so it's option A

A line passes through the point -10,9 and has a slope of 1/2. Write an equation in slope-intercept form for this line
vitfil [10]

Answer:

Step-by-step explanation:

The slope intercept form of an equation of a line is y = mx + b, where m is the slope and b is the y-intercept (the value of y when x=0).

Since the slope is (1/2), we can write:

y = (1/2)x + b

We want a value of b such that it forces the line to go through point (-10,9).  Enter that point in the equation and solve for b:

y = (1/2)x + b

9 = (1/2)*(-10) + b

9 = -5 + b

b = 14

The eqyuation of a line with a slope of (1/2) and goes through point (-10,9) is:

y = (1/2)x + 14

See attachment.

Svet_ta [14]

Answer:

150^o

Step-by-step explanation:

<u>Step 1:  Distribute the plus</u>

<u />(x + 15)^o + (135 - x)^o

x + 15 + 135 - x

<u>Step 2:  Combine like terms</u>

<u />x + 15 + 135 - x

(x - x)^o + (15 + 135)^o

0 + 150^o

150^o

Answer:  150^o
