Answer:
y=3x-4 is the slope-intercept form of the equation of a line. It is in the form y=mx+b.
m is the slope (often called "rise over run") and b is the y-intercept (the point where x=0).
The y-intercept is the point (0,-4).
We need one other point. This is where finding easy calculations pays off. How about where x=2, y=(3)(2)-4 = 2.
That's the point (2,2).

Salutations!
Insert brackets to make this calculation right 4x2+5-3
The brackets should be inserted outside 2+5. If you add brackets outside teh rest of the numbers the calculation would not make sense.
4 × (2 + 5) - 3
Hope I helped (:
have a great day!
A. 12*x + 2*y = 90
6*x + 2*y = 60
To write system of equation you just need to sum all solo and ensemble acts and make it equal to how much they will last for.
B. Here we can multiply second equation with negative 1 and add it to first equation.
6x = 30
x = 5
now we replace x in any of 2 equations to get y.
30+2y = 60
2y = 30
y=15
Solo acts are 5 minutes long and ensemble acts are 15 minutes long
Answer:
$162
Step-by-step explanation:
5r=20 10p=100 14t=42
100+42+20=162
5r+10p+14t=$162
