Look up the unit circle or type it into your calculator
Answer:
100
Step-by-step explanation:
5x4=20
20x5=100
Simplifying
3x + 4 = 7 + -2x
Reorder the terms:
4 + 3x = 7 + -2x
Solving
4 + 3x = 7 + -2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x' to each side of the equation.
4 + 3x + 2x = 7 + -2x + 2x
Combine like terms: 3x + 2x = 5x
4 + 5x = 7 + -2x + 2x
Combine like terms: -2x + 2x = 0
4 + 5x = 7 + 0
4 + 5x = 7
Add '-4' to each side of the equation.
4 + -4 + 5x = 7 + -4
Combine like terms: 4 + -4 = 0
0 + 5x = 7 + -4
5x = 7 + -4
Combine like terms: 7 + -4 = 3
5x = 3
Divide each side by '5'.
x = 0.6
Answer: x = 0.6
Answer:
a) y=2x+4 b) 2 c) 6 d) Sorry, you'll have to do that buy it's not too difficult! ^u^
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
1a) Well, if you add the y to both sides, you would get y=2x+4
1b) Since the main form is y=mx+b with m being the slope, the slope in y=2x+4 must be 2
1c) 6, because if x is 1, 2(1)+4=6
1d) I'm afraid you'll have to do that, just substitute in different numbers for x
