At the market, 5 light bulbs cost $9. How much do 7 light bulbs cost?
Rudiy27
Hello!

To solve this, find the cost of a single light bulb first, by dividing 9 / 5.

9 / 5 ==> 1.80

One light bulb is $1.80

Now, multiply 1.80 by 7.

1.80 * 7 = 12.6

7 light bulbs cost $12.6

Hope this helps! ☺♥

astra-53 [7]

Answer:

b. 3

Step-by-step explanation:

find equation of g(x):

(-16-(-10))/(-3-(-1))=-6/-2=3

apply a point

-16=3(-3)+n

-16=-9+n

n=-7

g(x)=3x-7

boyakko [2]

Answer:

y=x+2

Step-by-step explanation:

Given, m = 1

Eqn of st line is y = mx + c

y = 1*x + c

y= x + c ........eqn (i)

since, the line passes through the point (4,2)

4 = 2 + c

c = 4 - 2

c = 2

Now, Putting the value of c = 2 in eqn (i)

y = x + 2 is req eqn of line
