Answer:
y = 2x + 15
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 2 , then
y = 2x + c ← is the partial equation
to find c substitute (- 4, 7 ) into the partial equation
7 = - 8 + c ⇒ c = 7 + 8 = 15
y = 2x + 15 ← equation of line
4 shelves of consecutive even numbers
x , x + 2, x + 4, x + 6
5 ft = 60 inches
x + (x + 2) + (x + 4) + (x + 6) = 60....combine like terms
4x + 12 = 60
4x = 60 - 12
4x = 48
x = 48/4
x = 12 <==== one 12 inches
x + 2 = 12 + 2 = 14 <== one is 14 inches
x + 4 = 12 + 4 = 16 <== one is 16 inches
x + 6 = 12 + 6 = 18 <== one is 18 inches

<span>There are 318 fiction books in the class library. The number of non fiction book is 47 less than double the number of fictions book. About how many non fiction books are there in the class library?
Let the number of non fiction books me 'NF'.
Let 'F' be fiction
Double means '2', therefore:
2F - 47 = non fiction (NF)
2(318) - 47 = non fiction
As you can see brackets indicate multiplication, therefore you will be multiplying 318 and 2
636 - 47 = non fiction (NF)
Subtract 47 from 636
589 = nonfiction (NF)
There are 589 non fiction books in the library.
Hope I helped (:
Have a great day!</span>
Answer:
B
Step-by-step explanation:
x(2y - 3) ← multiply each term in the parenthesis by x
= 2xy - 3x
What angle measures? There are many problems in that.
