(2x+3y)+(7x-3y) First, group like terms together, so (2x+7x) + (3y-3y). Then simplify within the parentheses. 2x+7x = 9x and 3y-3y = 0, so you have 9x, which cannot be simplified any further. The answer is 9x.

Hello! Could you please help with these? It was due quite a long time ago. I have a D in this class and need to get my grades up

Digiron [165]

Answer:

16. $y=7x$

17. $y=0.5x$

18. $y=3x$

19. $y=2x$

Step-by-step explanation:

Equation is $y=kx$ where k is a constant of proportionality.

16.

$\frac{y}{x}=\frac{10.5}{1.5}=\frac{14}{2}=\frac{24.5}{3.5}=\frac{35}{5}=7$

So, equation is $y=7x$

17.

$\frac{y}{x}=\frac{1}{2}=\frac{2}{4}=\frac{2.5}{5}=\frac{3.5}{7}=\frac{1}{2}=0.5$

Equation is $y=0.5x$

18.

$\frac{y}{x}=\frac{6}{2}=\frac{9}{3}=\frac{15}{5}=\frac{18}{6}=3$

Equation is $y=3x$

19.

$\frac{y}{x}=\frac{4}{2}=\frac{8}{4}=\frac{14}{7}=\frac{18}{9}=2$

Equation is $y=2x$

If m <1= 36 what is the measure of its complement?

Vlada [557]

If A represents an angle, its complement is 90-A.

If m<1 = 36, then its complement is 90-36 (degrees), or 54 (degrees).
