Answer:
11.6
Step-by-step explanation:
Hopefully you want it solved, because that's what I'm about to do!
In order to solve this, you need to insert the value of t (which is 4.2) into the equation.
w(t) = 3 (4.2) - 1
Now that 4.2 is in the place of t, you solve it like you would any equation. Starting with multiplying 3 and 4.2 to get 12.6, and then subtracting one from that to get 11.6
Hope this helps!
Y=(1/4)x
take the number and multiply it by 1/4
Answer:
If you're multiplying them: 34x * 30x = 1020x^2
If you're adding them: 34x + 30x = 64x
If you're subtracting them: 34x - 30x = 4x
Step-by-step explanation:
Since y = x - 2, replace the y in 8x + 13y = 2 with x - 2:
8x + 13(x - 2) = 2
Simplify the equation by multiplying 13 by (x - 2):
8x + 13x - 26 = 2
Add 26 on each side:
8x + 13x = 28
Add like terms:
21x = 28
Divide by 21 on each side:
x = 28/21
Simplify the fraction:
x = 4/3
Now that we have solved for x we can now use it to plug into one of the equations to solve for y. Plug in 4/3 for x in y = x - 2:
y = (4/3) - 2
Subtract:
y = -2/3
Let's check the work to make sure it is right:
8(4/3) + 13(-2/3) = 2
32/3 + -26/3 = 2
6/3 = 2
2 = 2
As you can see the system of equations has been solved correctly.
To make the equation equal y
x=(y-5)^2
√x=√(y-5)^2
√x=y-5
this is because the 'root' cancels the 'square root'
√x=y-5
√x+5=y
