Answer:

Step-by-step explanation:

2x+3+5x-15

I can start off by combining like terms (2x and 5x with 3 and -15)

2x+5x+3-15

and my new equation will be 7x-12. Since they are not like terms (15 does not have x so I can't continue solving), 7x-15 will be my final answer.

Answer:

Group and add the x coefficients (factoring)

Add the other numbers: 3 and -15

2x + 3 + 5x – 15 = 2x + 5x + 3 – 15 = 7x - 12

When a graph line is vertical, it indicates that the relation is?

Sliva [168]

Answer:

When a vertical line is placed across the plot of this relation, it intersects the graph more than once for some values of x. If a graph shows two or more intersections with a vertical line, then an input (x-coordinate) can have more than one output (y-coordinate), and y is not a function of x.

judy has a piece of wood that is 4 5/8 feet long. she cuts off 3 feet 6 inches of the wood for a project. how much wood, in feet

Svet_ta [14]

there are 12 inches in 1 foot, so 6 inches is really just half a foot, thus 3'6" is really just 3.5' or 3½ feet.

now, let's convert those mixed fractions to improper fractions and then subtract, bearing in mind our LCD will be 8.

$\bf \stackrel{mixed}{4\frac{5}{8}}\implies \cfrac{4\cdot 8+5}{8}\implies \stackrel{improper}{\cfrac{45}{8}}~\hfill \stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{45}{8}-\cfrac{7}{2}\implies \stackrel{\textit{using the LCD of 8}}{\cfrac{(1)45~~-~~(4)7}{8}}\implies \cfrac{45-28}{8}\implies \cfrac{17}{8}\implies 2\frac{1}{8}$
