Answer:
$25.57
Step-by-step explanation:
First, you have to multiply $5.29 by 2 because she wants to spend $5.29 on 2 pairs of socks.
5.29 * 2 = $10.58
Then you want to add $10.58 and $14.99 together.
$10.58 + $14.99 = $25.57
Answer:
Linear-1,2,3,6
Nin-Linear-4,5
Step-by-step explanation:
A linear equation is an equation in which the highest power of the variable is 1.
Out of the given equations, the following are linear.
1) ![5x_1 + x_2 - 7x_3 = 4](https://tex.z-dn.net/?f=5x_1%20%2B%20x_2%20-%207x_3%20%3D%204)
2) ![5x_1 + 4.6x_2 + 12x_3 = -5](https://tex.z-dn.net/?f=5x_1%20%2B%204.6x_2%20%2B%2012x_3%20%3D%20-5)
3) ![3x_1 - x_3 = -5x_2 + 7](https://tex.z-dn.net/?f=3x_1%20-%20x_3%20%3D%20-5x_2%20%2B%207)
6) ![6x_1 - 4x_2 + x_3 = 0](https://tex.z-dn.net/?f=6x_1%20-%204x_2%20%2B%20x_3%20%3D%200)
These equations on the other hand are nonlinear.
4) ![3x_1x_2 + x_3 = 5](https://tex.z-dn.net/?f=3x_1x_2%20%2B%20x_3%20%3D%205)
5) ![4x_1^3 + x_2 = 5](https://tex.z-dn.net/?f=4x_1%5E3%20%2B%20x_2%20%3D%205)
No 4 contains a term which is the product of two variables therefore it is not linear.
No 5 contains a term whose highest power is 3. Such an equation is a Cubic Equation.
Answer:
see explanation
Step-by-step explanation:
Using the Pythagorean identity
sin²θ + cos²θ = 1 ( divide terms by sin²θ )
+
=
, that is
1 + cot²θ = cosec²θ ← as required
Answer:
Ok to make this easier for us we should switch these equations into y=mx+b so that it's easier for us to identify the slope and y-intercept:
to switch into y=mx+b form do this:
3x-y=5
-y=5-3x
y=-5+3x
y=3x+(-5)
2y-15x=8
2y=8+15x
y=4+7 1/2x
y=7 1/2x+4
THe slope of any line in y=mx+b form is m. Therefore in this equation:
y=3x+(-5) 3 is the slope
The y intercept of any line is the +b:
y=7 1/2x+4 -therefore 4 in this equation is our y intercept.
Now we can construct our equation in y=mx+b then into standard form (Ax+By=C)
since 3 is our slope and 4 is our y intercept the equatuon is :
y=3x+4
NOw all we need to do is move this into standard form:
y=3x+4
-3x+y=4
-3x+y=4 is your final answer
-hope this helped
