Answer:

CRT = 18

TRV = 72

V = 18

Step-by-step explanation:

CRT = 90 - C = 90 - 72 = 18

TRV = 90 - CRT = 90 - 18 = 72

V = 90 - C = 90 - 72 = 18

Which equation is not a linear equation? Question options: a) –4v + 2w = 7 b) x4= y c) x = -5 d) 2x + 3y = 5

Semmy [17]

Answer: Option b

$x^4= y$

Step-by-step explanation:

Linear equations have the following form:

$a_1x^n + a_2y^m + a_3w^s + a_4v^h = b$

Where the exponents n, m, s and h are always 0 or 1

To know which equations are nonlinear, identify among the options given, those that have exponents other than 1 or 0

Note that in option b) the exponent of the variable x is $n = 4$ therefore the equation is nonlinear

Finally the answer is the option b

Solve system by subsubstitution?<br> 14x-2y=46<br> -7x+y=-23

e-lub [12.9K]

$14x-2y=46 \\
-7x+y=-23 \\ \\
\hbox{solve the 2nd equation for y:} \\
-7x+y=-23 \\
y=7x-23 \\ \\
\hbox{substitute 7x-23 for y in the 1st equation:} \\
14x-2(7x-23)=46 \\
14x-14x+46=46 \\
14x-14x=46-46 \\
0=0 \\ \\
\boxed{\hbox{infinitely many solutions}}$

Atherine has $54. She plans to spend more than $20 of the money for a painting canvas. The rest will go toward paints. Each tube

horsena [70]

I think that she could buy 3 tubes of paint because that's $25.50 and that gives you 28.50 for the canvas.
